Farmer constraints on implementing Good Animal Husbandry Practices in Vietnam: case study on household pig production


Many studies have identified factors that influence the adoption of new technologies and management practices in livestock production to improve productivity, animal health and protect the environment. However, few studies have attempted to clarify the constraints faced by farmers in implementing these new management practices. This study identified 10 constraints on implementing good management practices designed to improve the health and productivity of pig production, ensure the health of workers, reduce environmental pollution and allow customers to trace the origins of their products, collectively known as Good Animal Husbandry Practices. Low output price and lack of capital were identified as the key constraints faced by 42.8% and 28.3% of farmers, respectively. Furthermore, specialized production was found to mitigate these two constraints in terms of income contribution, whereas access to credit was found to exacerbate them. Lack of knowledge was the only constraint perceived to be more severe by non-VietGAHP farmers than by their VietGAHP counterparts. Based on the above results for both VietGAHP and non-VietGAHP farmers, these constraints need to be addressed by improving financial situations through formal credit and focusing on specialized pig-producing households. For the non-VietGAHP group, delivery of information on new management practices through the government extension services should be implemented.
