Perspectives of the ACIAR-funded research projects in Northern Lao PDR

Authors: Bethanie Clark, Brianne Pepper, Amanda Bouassi
Edited by Prof Peter Windsor

Bethanie, Brianne and Amanda are fourth year Animal and Veterinary Bioscience students from the University of Sydney School of Veterinary Science. They were awarded New Colombo Plan Scholarships to travel to Laos in February 2018 and work in the ACIAR funded projects ‘Development of a biosecure market-driven beef production system’ (ACIAR AH/2012/068) and ‘Enhancing transboundary livestock disease risk management in Lao PDR’ (ACIAR/2012/067) in northern Laos. Their visit was aligned with their final year Honours Projects, requiring them to be based in Luang Prabang for 4 weeks.

Prior to their trip, they each conducted preliminary research on the topics they had chosen; Amanda on nutrition and the use of urea molasses blocks; Brianne on current biosecurity and animal disease status, prevention and treatment practices of smallholder farmers; and Bethanie on the effects of Neospora caninum and Leptospira interrogans on reproductive performance in buffalo. This work provided insights into the status of the agricultural sector in the country although did not prepare them for the actual experiences obtained in the villages and the  current farming practices utilised in Laos. They visited villages close to Luang Prabang (LPB) for two days, helped take faecal samples from calves and vaccinating recently purchased cattle against Foot and Mouth Disease. It was amazing to see how simple farming practices were and how improvising with the limited local resources enabled progress, including the use of bamboo to form a bleeding pole, fencing and a crush. From conducting both field and office work, the students s experienced the various challenges of working in a developing country.

Highlights included visiting the Laos Buffalo Dairy near LPB, A trip to Xayaburi province, and participating in the Projects Midterm Review Meeting. The Laos Buffalo Dairy was recently established by Suzie Martin, an Australian who wanted to improve the future livelihoods of buffalo farmers through participation in her business. The production system is unique as it involves ‘renting’ buffalo from local villages during late pregnancy and lactation and then returning them to the farmers when lactation ceased and they are pregnant again. The buffalo milk is utilised to make cheeses, yoghurt and ice-cream products that are sold locally to customers and also to local hotels and restaurants. Students from local universities may work at this farm and are taught basic biosecurity practices and how to work in a western kitchen. These skills are crucial for Lao PDR as biosecurity is rarely practiced in this country due to the very limited knowledge of farmers and advisors.

The students also travelled to Xayaburi province for two days for the recently initiated  Business Partnership Platform(BPP) DFAT-funded project on ‘Urea molasses blocks to improve large ruminant productivity and profitability for smallholder farmers in Lao PDR’. They visited one of the project farms and witnessed the positive interaction between the project staff and the farmers, highlighting the importance of having good relationships with farmers when conducting field Livestock research in Laos. Amanda was able to observe the implementation of the urea molasses blocks trial, noting that the blocks were offered to small groups of cattle (eg three cattle per block and one buffalo per block) as previous research identified that changes in growth rate were less obvious when too many animals has access to a block. The students were fortunate to attend the annual elephant festival in Xayaburi. At the festival, locals and tourists celebrated the national animal of Laos, the elephant and this festival gave the students an incredible insight into the culture and traditions of the local people, with about 70 elephants in attendance, traditional Laotian music, food and a martial arts performance by the local youth of Xayaburi.

In their third week in Laos, the students attended the Projects Midterm Review Meeting in Luang Prabang, where the previous achievements of the project and future initiatives were discussed. This meeting enabled the students to see the bigger picture of the considerable work that they were contributing to during their month in Laos. During dinner with the meeting attendees from Australia and Laos, the students learned of the value of applied research in developing countries, how travelling can be part of a career, and the impacts that ACIAR-funded research has made around the world.

In the final week Bethanie and Amanda returned to the Buffalo Dairy and also visited Pik Yai and Khokman villages in Luang Prabang province, with the local Laos team, collecting blood samples from buffalo and completing a risk factor surveys with the farmers. The blood samples will be tested for antibodies to Neospora caninum, Leptospira interrogans and bovine viral diarrhoea (BVD pestivirus) as all 3 potential pathogens have recently been identified in buffalo in Laos (this work is for Bethanie’s Hons project).

Progressing research for control of Toxocara mortality in calves in Laos, January 2018

Ms Geri Pearson, DVM final year student, edited by Prof Em Peter Windsor

An important part of the current MLR research projects in Laos includes educating farmers on internal parasites causing mortalities in calves, particularly Toxocara vitulorum. This roundworm species is found in the small intestines of bovines where the adult worms lay eggs excreted in the faeces. Ingestion of the hatched larvae from the environment allows migration of the larvae throughout the respiratory tract, liver, kidneys and other organs and finally the small intestines. Lactogenic transmission (via milk) to calves occurs with larvae remaining in the small intestine into maturity. Migrating larvae can cause serious damage to organs of adult cattle resulting in ill-thrift, weight loss and poor production however the biggest losses occur in infected calves with high mortality rates common. The hot and humid conditions of South East Asia are highly suitable to infections with Toxocara vitulorum and the parasite is endemic in Lao cattle and buffalo, causing serious economic problems for farmers.

Due to the typical lack of cattle handling facilities found on Laos farms it is very difficult for farmers to administer parasite control. During the February 2016 visit, the Australian company 4 Season Company Pty Ltd donated 400 fenbendazole medicated molasses blocks (MMBs) for trials in Laos, providing an easy route of administration for anthelmintic control and nutritional supplementation to improve herd body condition scores. Preliminary trials on the use of these MMBs conducted by University of Sydney AVBSc student Tereza Nemanic showed very positive results during research on these blocks and  larger trials have recently commenced  with five farmers in Luang Prabang province.

A recent follow up trip was conducted in January 2018 to collect faecal samples from calves and assess body condition to determine the efficacy of these MMBs. Faecal egg counts (FEC) of these samples will be conducted at the Lao Department of Livestock and Fisheries laboratory in Luang Prabang. Faecal collections will continue into February to allow assessments of FEC at 1, 14, 28 and 56 day intervals and help determine the potential efficacy of this approach if applied a larger scale. This research work has received a boost recently with support from DFAT through a successful application by 4 Seasons & the MLR team for a Business Partnership Platform (AUBPP) grant examining the potential for multiple applications of molasses blocks in Laos and potentially the broader Mekong and southeast Asian region.

Correspondence with farmers during the recent visits indicate they are very pleased with the results as the health and body condition score of their herds continues to improve. Further information on this and other MLR projects aimed  at improving large ruminant efficacy and regional food security can be found on the Mekong Livestock Research Blog:

Additional research on parasitic control has also recently been conducted by Dr Sonevilay Nampanya and PhD students Ms Luisa Olmo and Ms Nichola Calvani who all recently presented at the 26th International Conference of the World Association for the Advancement of Veterinary Parasitology (WAAVP) in Kuala Lumpur, Malaysia in September 2017.

Perseverance and Patience on the MAD journey

Isabel MacPhillamy

The MLR team has recently begun the transition from paper-based surveys to the use of mobile acquired data (MAD) surveys using the e-platform CommCare. This blog highlights recent experiences from this journey in Cambodia.


Figure 1. Collecting field data in Cambodia is often laborious as it frequently occurs during times of multiple activities, such as weighing & vaccinating cattle involved in the project.

As the new project officer for the MLR team, an important task was to begin the transition of our work to the use of the more efficient data entry and management platform CommCare. The team has been investigating this transition and new technologies for the last year or so, with one of our PhD students, Nichola Calvani, being able to attend a CommCare workshop earlier in the year. In August at the Crawford Fund Conference in Canberra, the role and responsibilities we have as researchers when using this data collected from smallholders, and how we can start to ‘give back’ to the farmers in real time, was emphasised. In the past in some of our project activities it has taken months for data sets to be entered into the computer and analysed, often due to the multiple commitments of many of our in-country staff collaborators. We hope that the shift to CommCare will greatly decrease the time any of us need to spend in entering and cleaning data, allowing us to spend more time on other important activities, such as extension advice on improving health & productivity!

Peter Windsor and I first trialled the platform in August at an OIE SEACFMD regional coordinators meeting in Pakse in southern Laos. We were able to efficiently conduct a Biosecurity Practices survey with the attendees, with most able to complete the survey on a hand-held tablet during coffee and lunch breaks. The system was considered very user friendly by all involved and allowed us to promptly conduct an analysis of the data.

We then hoped to implement the new technology in our longitudinal cattle survey in Cambodia. This is a large and extensive survey involving 16 locations and up to 2000 cattle and buffalo. The team was preparing for the fourth data collection so we were hoping to incorporate this data into the CommCare app in the expectation that we could begin to give real time feedback to farmers. Letting farmers know whether their cattle are gaining or losing weight since the last collection period is likely to be highly motivational. After a few team discussions and some ad-hoc research, we decided to contract the app developer, the Australian company AgImpact. Their team did a fantastic job developing the app and were always available on the other end of Skype message if anything was needed. I headed over to Cambodia in October for four weeks of training, fine-tuning and deploying the app. Our Cambodian team collaborators quickly saw the advantages of the technology and enthusiastically adopted MAD because of the time saving benefits.

Day One of deployment highlighted how important it is to involve whoever is collecting the data with the development of your CommCare app. Unfortunately for our team, due to timing issues, this wasn’t possible and there were moments in those initial deployment days were I had to ‘let go’ of how I thought things should happen and let the team work out how to make the app work best for them. The team face numerous challenges when weighing and vaccinating the cattle due to the limited facilities, with some farmers still hesitant to either vaccinate or weigh their pregnant cattle. Also, setting up the temporary cattle crush at either one or two locations per village in the tropical heat is a challenge. By the end of the first week the team seemed to be incorporating the app in a way that worked well for them and the challenges they faced. They had also expressed interest in learning more about the app development so that they could start to incorporate this new technology into their other roles outside the project.

During the four weeks I spent in Cambodia in October-November, I was fortunate to experience the three day ‘Bon Om Touk’ or water festival. This is festival celebrates the end of the rainy season and reversal of the flow of the Tonle Sap River into and from the mighty Mekong River in Phnom Penh. Boat racing is a feature and I caught the last day of the boat racing and was amazed at the huge numbers of people crowding along the river bank! I also got to enjoy a little side trip to the Angkor Wat temples one afternoon after the vaccination activities in Siem Reap. The experience was just as magical as it was 10 years ago when I first visited Cambodia I also visited the land mine museum, a sobering reminder of the challenges that many of our project farmers (and colleagues) experienced in their lifetimes during the devastation of the Pol Pot era. One colleague told me stories of the manual labour he was expected to do as an eight year old, plus the death of family members due to starvation. The horrors that the peaceful Cambodian people had to endure in the 5 year rule of the Khmer Rouge is unfathomable and a reminder of how privileged many of us from western societies have been spared from the struggles of severe civil unrest.

MLR team present recent FMD research at the 2017 GFRA Conference in Korea

Authors: Peter Windsor & Jim Young


The Mekong Research Livestock Team from The University of Sydney School of Veterinary Science presented 4 papers on FMD in Laos, Cambodia & beyond, at the 2017 GFRA (Global Foot-and-Mouth Disease Research Alliance) Scientific Meeting held on the 25-27th of October in Incheon near Seoul, Korea.

The team contributed 2 papers to the session on ‘FMD viral ecology & epidemiology’. Firstly, Corissa Miller presented work from her MVPHMgt research project in a paper entitled ‘Risk Factors for endemic and emerging FMD viruses on smallholder farms in Lao PDR’ where she identified that quarantine for 2 weeks of animals entering the village was protective of infection and that farmers using communal grazing had 5.5 times the odds of having FMD in the animals. This was followed by a presentation from the recently completed PhD of Jim Young entitled ‘Investigation of smallholder farmer biosecurity and implications for sustainable FMD control in Cambodia.’ Jim identified the lack of basic biosecurity practices in Cambodian villages from a baseline study of KAP (knowledge, attitudes & practices) of smallholder farmers (n=240) and that cattle incomes were related to region, numbers of calves born, forage area, vaccination and numbers of cattle purchased.

In the next session on socioeconomics of FMD in endemic and non-endemic settings, Sonevilay Nampanya presented a paper on the ‘Socioeconomic impact of the FMD vaccination project implemented in northern and central Lao PDR’. This study examined the changes in livelihoods & income from livestock of smallholders in several provinces in a potential FMD-free zone between 2012 and 2016, when 1.6m doses of vaccine were provided by the Australian STANDZ (Stop Transboundary Animal Disease & Zoonoses) program & the Japanese Trust Fund to the Lao Department of Livestock & Fisheries to administer strategically. Although it was found that only 62% of the susceptible bovine population was vaccinated and no cases of FMD were reported after 2013, this study showed the dramatic differences in mean annual household incomes between regions (>$5000 versus ~$1200), that FMD vaccination was generally well regarded by farmers, and the project may have provided a satisfactory level of protection to suppress the disease from being recognised in the targeted zone. This was followed by Peter Windsor presenting a paper entitled ‘Was biosecurity awareness more important than vaccination of pigs for FMD control in the Philippines?’ that promoted the importance of improving biosecurity practices to ensure FMD control interventions are sustainable. This included recent findings on ways to improve KAP of smallholders in Lao & Cambodian villages & data collected recently from SEACFMD (Southeast Asian & China FMD program) coordinators and OIE (World Animal Health Organisation) delegates on their current biosecurity programs at the householder, village, commercial and national levels. It was concluded that biosecurity practices in FMD endemic countries is generally poor and that public awareness messages on FMD need to be revised & renewed.


There were over 200 attendees at this conference from many parts of the world and it was particularly pleasing to see work conducted in endemic countries in Africa, Asia and the middle east where the FMD virus populations are emerging as increasingly dynamic. It appears that the rapidly changing trading patterns of animals and their products has increased the complexity of managing the disease, particularly because of the challenge of ‘vaccine matching’ to the newly emerging serogroups and their topotypes in the endemic countries. The final session on research gaps was of particular interest where the frustrations of current vaccine efficacy & understanding of virus movement were discussed amongst the many issues raised in the presentations during this conference including the themes introduced by the MLR on biosecurity & the importance of public awareness programs involving all stakeholders in the ruminant & porcine value chains in FMD endemic countries. The MLR team greatly enjoyed this very focused program that shared the latest research on this most enigmatically important threat to global food security.

Presentations from the conference will become available shortly at the GFRA website:

Sharing knowledge and understanding of important livestock parasites and their control at the 26th WAAVP conference in Malaysia, September 2017

 Dr Sonevilay Nampanya, Ms Luisa Olmo and Ms Nichola Calvani

Edited by Prof Peter Windsor & A/Prof Russell Bush


The Mekong Livestock Research (MLR) team has been working on livestock parasites and their control in smallholder large ruminant production systems for many years, progressing our understanding on their prevalence and impact on smallholder livestock health and production. Of the numerous important livestock parasites in the Mekong, the team has particularly focused on Fasciola gigantica (Fascioliasis), Toxocara viturlorum (Toxocariasis), and most recently, the reproductive protozoan parasite Neospora caninum.


Three of our MLR team, Dr Sonevilay Nampanya and PhD students Luisa Olmo and Nichola Calvani, were selected for oral presentations at the 26th World Association for the Advancement of Veterinary Parasitology (WAAVP) conference, Kula Lumpur, Malaysia, Sept 4-8, 2017. This is the largest veterinary parasitology conference in the world, held every two years to provide opportunities for parasitologists and animal health researchers to learn and share their recent findings in parasitology. The three MLR presenting members included:


  1. Dr. Sonevilay Nampanya presenting on the control of SE Asian liver fluke, Fasciola gigantica, by use of the innovative and successful approach of including the flukicide triclabendazole in anthelmintic-medicated molasses blocks (Figure 1). Sonevilay and the other MLR team members were impressed with the depth of information presented at the conference, including information on the parasites of bees, pets, livestock and wildlife. There were also many research topics presented on Fasciola hepatica and developments in drug resistance, although there was very limited information on Fasciola gigantica and large ruminant smallholder production systems. This encourages us to keep working on our current research to fill the gaps in scientific knowledge that can assist smallholder farmers to find more sustainable methods of parasitic control, such as use of improved diagnostics and use of novel approaches to administration of anthelmintics, including medicated block technology.

  1. Ms Luisa Olmo presenting on seroprevalence investigations of the protozoal pathogen Neospora caninum, potentially a major cause of abortion in cattle and buffalo in Lao PDR (Figure 2). Luisa reflected on the occurrence of globally important pathogens causing abortions and reproductive wastage in large ruminants throughout the Mekong. Despite the limited information available, it is suspected that bovine abortion occurs in Laos, particularly as measurements of large ruminant reproductive performance indicate that extended inter-calving intervals of about 15 months in cattle and >20 months in buffalo are occurring. In 2016, Luisa shared cattle and buffalo sera with the College of Veterinary Medicine and Life Sciences at the City University of Hong Kong for analysis for reproductive pathogens, and antibodies against Neospora caninum were found in almost 70% of the buffalo samples. This apicomplexan protozoan parasite can be maintained in cattle and buffalo species through transplacental transfer to the foetus, potentially causing fatal pathology. Cattle and buffalo can also be infected or re-infected by co-rearing of bovines with canines that are shedding the protozoan oocysts in their faeces, resulting in reproductive wastage. When presenting serology work at an international science conference, context is important and Luisa commenced by describing the smallholder farming system in the Mekong where the household is focused on food security, growing rice and cash-crops, with cattle and buffalo husbandry occurring as a subsistence activity. Luisa explained why epidemiological investigations to develop strategies for smallholder farmers to break the parasitic cycle are required. At the conference Luisa was able to meet our collaborator from Hong Kong, Professor Michael Reichel to discuss current and future research prospects. The MLR team are now conducting further serological and epidemiological surveys aimed at determining risk factors for Neosporosis that can inform preventative interventions.

  1. Ms.Nichola Calvani, presenting research findings on improving the diagnosis of Fasciolosis using molecular techniques (Figure 3). Nichola’s paper was titled “scrambled eggs” and describes a sample preparation workflow for the molecular detection of Fasciola spp. eggs in faecal samples that is highly sensitive and capable of detecting a single liver fluke egg. The work was recently published in the journal PLoS Neglected Tropical Diseases, with one of Nichola’s images selected for the September issue cover. The workflow will enable highly sensitive and species-specific detection of Fasciola eggs in faecal samples during MLR PhD work on Fasciolosis in the Mekong, where this parasite has been shown as an important cause of decreased production in large ruminants. As the parasite requires an aquatic snail as an intermediate host, rice paddy’s along the Mekong are areas of high risk to both ruminants and potentially people. Fasciolosis is considered a major zoonotic threat, with 91 million people considered at risk of infection around the world each year. The new diagnostic approach was well-received at the WAAAP in Malaysia and provides an opportunity for the MLR team to contribute capacity building in Laos and Cambodia by improving the technical skills of laboratory staff in our partner countries.


At the 26th WAAP, Sonevilay, Luisa, Nichola took every opportunity available to at the conference to network with other researchers working in their field. Nichola is subsequently in the process of organising a month-long research exchange in Europe next year where she anticipates learn new skills that will directly relate to her work on liver fluke in large ruminants in Cambodia and Laos.


Figure 3. Nichola Calvani and Luisa Olmo at the 26th International Conference of the WAAVP in Kuala Lumpur, Malaysia


All 3 MLR team members successfully delivered their presentations and drew attention to the work of our team, receiving comments and suggestions that may enable improved our research outcomes. They also had the opportunity to discuss and learn from experts on numerous important livestock parasites and gain perspectives on food safety and parasitic contamination from all over the world. The MLR work on improved diagnostic tests and parasite control presented by Sonevilay, Luisa and Nichola is leading to published papers that will document the improved likely knowledge of both liver fluke and Neosporosis epidemiology and control in the Mekong region and beyond, inevitably benefiting the livelihoods of smallholder farmers through improved livestock production efficiency.

The Cambodian champion smallholder farmer raising cattle for business

Prepared by Dr. Suon Sothoeun, Project leader ACIAR project AH/2011/014

The livestock project “Village-Based Biosecurity for Livestock Disease Risk Management in Cambodia, ACIAR, AH/2011/014” commenced in 2015 and continuing until 2018, was developed following the success and recommendations from the project “Best practice health and husbandry of cattle, Cambodia, ACIAR, AH/2005/086”, conducted from 2007 to 2012. A feature of project AH/20005/086 was the high levels of adoption of tropical forage plantations to improve the nutrition of cattle and leading to improved rural livelihoods through time-saved in feeding cattle and improved financial returns when selling cattle with improved condition scores. Both projects received funding from the Australian Centre for International Agricultural Research (ACIAR) through the Australian Ministry for Foreign Affairs and are implemented by the Cambodian General Directorate of Animal Health and Production (GDAHP) in collaboration with The University of Sydney.

In the AH/2011/014 research project, the focus is to extend the research on improvement of animal health and production beyond just cattle and buffalo activities, through interventions that stimulate farmer interest in improved biosecurity for all their livestock species. This project is investigating a whole of village approach to improved animal raising, including nutrition, breeding, husbandry, disease prevention and control, and management of cattle, poultry and pigs, whilst encouraging the farmers to raise the animals commercially.

Previous research has identified the importance of champion farmers in extending the research findings from these projects. Below is the history of a primary school teacher and champion farmer Mr Chhea Ben, who lives in Sen Ouk village, Kus commune, Tramkak district, Takeo province, with his wife, Mrs. Sam Sodany, and their two children. The family have been successfully raising cattle commercially and has earned a reasonable income from this activity every year since 2011. Through income earned from cattle raising , Mr. Chhea Ben’s family has improved their lifestyle. He has also become a ‘famous farmer‘ based on his success in growing forages and raising cattle, including his importation of superior Brahman genetics. This provides an example for other farmers who can observe that successful cattle raising can generate superior incomes, improve living standards and enable rural families to stay in their villages and not have to go to other countries to find work.

In 2003, Mr. Chhea Ben and his family lived in a small wood house. Mr. Chhea Ben’s income was based on his teacher’s salary of 220,000 riels per month (USD 55.00). In addition to his teaching, he engaged in agriculture:

  • owned 1.2 ha of rice paddy;
  • planted 0.4 ha of Taro;
  • raised 3 local breed cows a calf);
  • Had some chickens.


Picture 1. Mr. Chhea Ben, his wife Mrs. Sodany and two children (2008)

In 2008, the ‘Best practice health and husbandry of cattle, Cambodia, ACIAR, AH/2005/086’ project started in Chheng Toung commune in Tramkak district, Takeo province. The project introduced and encouraged farmers to plant forage. The project provided 4 types of forage seed: 1/Brachiaria brizantha–Marandu, 2/Brachiaria hybrid-Mulato 2, 3/Paspalum atratum–Terenos and 4/Stylo 184. This project also provided training on forage cultivation techniques. Mr. Chhea Ben contacted a farmer in the project in Chheng Toung commune in Tramkak district and asked for forage seed to test himself for planting and feeding to his cattle. Knowing the farmer interest on forage cultivation, the project started to visit his house and supported him the establishment of forage. The decision to provide forage seeds and technical advice to this farmer outside the project was made to extend the activities to another place.

In 2008, Mr Chhea Ben planted 0.5ha of forages and raised 10 head local cattle including 7 cows and 3 male calves.

In 2011, Mr Chhea Ben had 8 cattle (changed from local cattle to crossbred cattle) including 7 cows. He started to build a cattle pen (10m x 8m) including a water trough and he put netting around the cattle pen to protect from insects. All the cattle were kept in a pen and provided cut-carry forages 3 times per day from the 0.5ha forage plot. In 2011, the income from cattle raising was 18,271,000 riels (4,456 USD) and Mr Chhea Ben was the 1st winner entitled as the best champion farmer for Cattle Raising during the Annual Farmer conference, organised by the Ministry of Agriculture, Forestry and Fisheries.

Income from cattle raising and forage selling

From 2008 to 2016 Mr. Chhea Ben sold 36 head of cattle (4 head per year) and earned 18,271,000 riels (USD 34,200). He also earned money from leasing his bull for breeding and earned USD 2,250 (300 head). Total income from cattle was USD 36,450. The average annual income was USD 3951. During 5 years from 2012 to 2016, total income from selling forage seedlings was 2,100 USD per year. In 2017, Mr. Chhea Ben had 2 hectare of forage and sold 4 cattle for 5000 USD and earned 4000 USD from selling forage seedlings and grass.

Change from local cattle breed and free-grazing to crossbred cattle, forage feeding, cattle housing, biosecurity and good management.

In the last 10 years from 2008 until 2017, Mr. Chhea Ben and his family have improved their living standard and now have a good reputation in Cambodia. He is a champion cattle farmer, forage seedling distributor, advisor on forage planting to other farmers throughout Cambodia and his farm is good field visit site.

Australian students experience smallholder cattle farmer productivity research and extension in Cambodia

Authors: Holly Harrison, Holly Laurence & Rhiannon Phillips

Editors: Peter Windsor & Isabel MacPhillamy


During June and July 2017, the authors, Rhiannon and the Two Holly‘s, all final year Honours students from the Bachelor of Animal and Veterinary Bioscience degree (BAVBioSci) in The Sydney School of Veterinary Science at The University of Sydney (USYD), travelled to Cambodia to conduct applied research projects within the larger ACIAR-funded project “Village-based biosecurity for livestock disease risk management in Cambodia”. The students were based in the capital city Phnom Penh working with the local partners in the General Directorate of Animal Health and Production (GDAHP) and collaborating with project team members from both the GDAHP and the University of Sydney.


Each student was tasked to prepare a survey that aimed to explore with smallholding farming families, several different aspects of their farm production system. The Honours project topics included: cattle reproductive health; vaccine usage, availability and storage; and gross margin budget analysis of interventions used to improve livestock productivity. Under the guidance of the GDAHP team members, the students travelled to project village sites in the provinces of Takeo and Tbong Khmum, where they met with 12 smallholder farmers and their families, inspecting their livestock-raising facilities and conducting interviews to gather information for their research. This was achieved with the help of a local team GDAHP members Phallaep and Vitou as translators plus USYD PhD student Katherine Ashley who has developed reasonable fluency in Khmer language during her thesis work.


The local farmers were enthusiastic and graciously offered their help, plus samples of their produce, including coconuts, grapefruit, mangosteen and peanuts. Of course this all was well accepted by the hungry students keen to broaden their experience of Khmer cuisine. In addition to appreciation all of the fresh produce, the students thoroughly enjoyed meeting the farming families and learning details of the constraints to smallholder production in Cambodia. It was clearly apparent that livestock have an important socioeconomic role in Cambodian rural livelihoods and cattle in particular have been increasingly important with low return to rice production and other commodities. Forage growing for the feeding of livestock was found to be far more beneficial than the growing of rice and other crops, including cassava and most vegetables.

One of the highlights for the students was being able to interact with the village children and spend time learning about the rural society, culture, education and history in Cambodia. Many of the older farmers experienced the ‘ground zero‘ history of the ‘Pol Pot time‘ during the disastrous genocidal Kampuchean Khmer Rouge (KKR) revolution of 1975-1978. However, there were many smiling faces when the students tested their newly acquired fledgling Khmer language skills and particularly when Holly Harrison gave some of the children Koala toys delivered all the way from Australia!

The research team visited two businesses that supplied veterinary medicines and vaccinations to smallholder farmers and their information enabled Holly Laurence to assess the availability of these products within Cambodian rural communities as part of her research. Much needs to be done to ensure a satisfactory ‘cold chain‘ can be developed in rural Cambodia that can deliver efficacious livestock vaccination, particularly for endemic Foot-and-Mouth Disease. Rhiannon was fortunate to be able to stay on for a week and attend a cattle reproduction workshop for 25 participants, hosted by the GDAHP courtesy of HE Dr Sen Sovann and in-country ACIAR project leader Dr Suon Sothoeun. The workshop was conducted by the Australian team of Professor Peter Windsor, Bega Veterinary Practitioner Peter Alexander, and USYD PhD student Luisa Olmo who is examining cattle reproductive health. The first day addressed reproductive anatomy and physiology, measurement of reproductive outcomes, and work on understanding constraints to reproductive efficiency. The second day was practical training at the Tamao Breeding Station in Takeo where participants were trained in clinical examination, body conditions scoring and pregnancy testing. The next day the research team visited the Sen Ouk village project site in Takeo for a project meeting with a grateful and enthusiastic group of farmers involved in the distribution of forage seedlings to improve cattle nutrition.


This reproduction workshop was for Provincial and District officers working in animal health and production, encountering the challenges of working with farmers expecting cows to regularly deliver calves from low condition score Haryana and Indigenous crossbred cattle in rural Cambodia. Previous work by the USYD-GDAHP research team established that Cambodian cattle have a mean inter-calving interval of 20months (in Australian beef cattle the target is 12months). This low reproductive efficiency is considered mainly due to endemic nutritional anoestrous in Cambodian cattle provided with poor nutrient availability from the largely ‘cut and carry‘ feeding system in widespread use, particularly in the wet season. Rhiannon presented her preliminary findings for a draft calving calendar that encourages alignment of calving with seasonal availability of a rising plane of nutrition when energy demands of lactating cattle are 2.5x those of dry (non-pregnant) cattle. The calendar was very well received and useful feedback was provided, enabling Rhiannon and the team to progress her work and understanding. As some attendees have commenced artificial insemination activities in response to demand for better quality cattle, future training is planned that will address problems of advanced reproductive technology in cattle.


In conclusions, the BAVBioSci Hons students, supported by New Colombo Plan mobility grant funding, enjoyed learning about the Cambodian smallholder productions system and participating in research that is improving the livelihoods of the rural poor in this most interesting of countries. They also appreciated the rich culture and history of the Khmer population, both during their work and in ‘down-time‘, visiting many historic locations, including the spectacular temples of Angkor Wat and the strangely dark and sobering monuments of the KKR killing fields. Like many visitors to Cambodia, these contrasting experiences are challenging and informative, although unlike most tourists, the Hons students gained much deeper insights into rural Cambodian life that enabled them to connect and communicate with famers for a much richer experience of Cambodia.
