Changes in farmer animal health and biosecurity knowledge, attitudes and practices: Insights from Cambodia and Laos

Livestock agriculture in Cambodia and Laos is severely affected by endemic and exotic transboundary animal diseases, impacting household livelihoods and food and nutritional security. Collaborative animal health and biosecurity projects were conducted in each country between 2015 and 2019 aimed at increasing smallholder livestock production through mainly knowledge-based interventions in large ruminant disease prevention, nutrition, reproduction and marketing access. This study's objectives were to identify baseline animal health and biosecurity knowledge, attitudes and practices (KAP) of farmers, and temporal changes in key attitudes and practices associated with improved knowledge. Data for each country were analysed separately, and a formal between-country comparison was avoided due to major implementation and management differences. Binomial logistic regression without random terms compared the overall knowledge scores between 2015 and 2018 in each country, and binomial logistic regression with random terms was used to investigate possible associations between animal health and biosecurity knowledge scores and attitudes and practices. In Cambodia, the average animal health and biosecurity knowledge score increased from 4.8 (±2.2)/17 in 2015 to 13.0 (±2.8)/17 in 2018 (p < .0001). In Laos, the average scores improved from 7.2 (±2.5)/12 in 2015 to 7.9 (±2.9)/12 in 2018 (p = .0003). Clinical signs of foot-and-mouth disease were accurately reported by 100% of Cambodian and 88% of Lao project farmers, and overall, attitudes and practices improved in both countries over the study period. The belief that vaccination can improve livestock value was associated with increasing knowledge in both countries (Cambodia: OR 1.45, 95% CI 1.24-1.68, p < .0001; Laos: OR 1.43, 95% CI 1.16-1.75, p = .0006) as was the use of the services of village para-veterinarians if they had better training (Cambodia: OR 1.76, 95% CI 1.20-2.58, p = .004; Laos: OR 2.02, 95% CI 1.19-3.41, p = .009). However, the source of livestock information (District veterinary officials) was the only practice associated with knowledge in both Cambodia and Laos. The influence of resource scarcity on farmer decision making and knowledge measures was considered of particular relevance to the findings.

The Impacts of Animal Health Service Providers on Antimicrobial Use Attitudes and Practices: An Examination of Poultry Layer Farmers in Ghana and Kenya

International organizations and governments have argued that animal health service providers can play a vital role in limiting antimicrobial resistance by promoting the prudent use of antimicrobials. However, there is little research on the impact of these service providers on prudent use at the farm level, especially in low- and middle-income countries where enforcement of prudent-use regulations is limited. Here, we use a mixed-methods approach to assess how animal health-seeking practices on layer farms in Ghana (n = 110) and Kenya (n = 76) impact self-reported antimicrobial usage, engagement in prudent administration and withdrawal practices and perceptions of antimicrobial resistance. In general, our results show that the frequency of health-seeking across a range of service providers (veterinarians, agrovets, and feed distributors) does not significantly correlate with prudent or non-prudent use practices or the levels of antimicrobials used. Instead, we find that patterns of antimicrobial use are linked to how much farmers invest in biosecurity (e.g., footbaths) and the following vaccination protocols. Our results emphasize that more research is required to understand the interactions between animal health service providers and farmers regarding antimicrobial use and antimicrobial resistance. Addressing these gaps will be crucial to inform antimicrobial stewardship training, curriculums and, guidelines whose ultimate purpose is to limit the selection and transmission of antimicrobial resistance.

Breaking the chain of zoonoses through biosecurity in livestock

Increases in global travel, trade and urbanisation are leading to greater incidence of zoonotic disease, and livestock are often a key link in the spread of disease to humans. As such, livestock vaccination strategies, as a part of broader biosecurity solutions, are critical to both animal and human health. Importantly, approaches that restrict infectious agents in livestock, not only protects their economic value but should reduce the potential for spill over infections in humans. Biosecurity solutions to livestock health can take a number of different forms and are generally heavily weighted towards prevention of infection rather than treatment. Therefore, vaccination can provide an effective component of a strategic approach, particularly as production economics dictate the use of cost effective solutions. Furthermore, in an evolving global environment there is a need for vaccines that accommodate for lower socioeconomic and rapidly emerging zoonotics.
