Abstract

Antimicrobials are a core aspect of most livestock production systems, especially in LMLMs countries. They underpin
efficient use of scarce feed resources and stabilize returns on capital and labor inputs. AMU plays a role in
generating robust animals, yet AMU in livestock is linked to antimicrobial resistance (AMR) changes across society
and within the environment. The reduction of AMU in livestock is a broad strategy. It assumes that AMU is at an
inappropriate level and one that can be reduced with no consequences, change, or investment. Yet it is known that
this is not the case from a practical point of view. There are different alternatives to antimicrobials such as
immunology, management, and biosecurity. However, the implication of those alternatives’ strategies requires the
cost (capital, variable, and labor) as well as require the evaluation of related impacts (disease, performance in
production, AMR). The Vietnamese Platform for Antimicrobial Reduction in Chicken Production project implemented
during 2016- 2019 is one of the first large-scale interventions focused on AMU reduction implemented in Southeast
Asian animal production systems. The project targeted small-scale poultry farms in the Mekong Delta region of
Vietnam using a “randomized before-and-after controlled study”. It aimed to provide farmers with a locally adapted
support service (farmer training plan, advisory visits, biosecurity, and antimicrobial replacement) to help them
reduce their reliance on antimicrobials. Using a partial budget analysis framework in comparison to two scenarios
(status-quo and alternative), the net benefit of applying intervention strategies at the farm level varied from -2.74
USD to -44.83 USD per production cycle. At the project level, the analysis showed that the achievement of
antimicrobial resistance reduction benefit under the current knowledge and technologies require the investment of
at least 40,304 USD per 102 enrolled farms during three years project. The results highlight the reduction in farm
profits and therefore recommend the policies on financial support, legislation, and information as the potential
solution to facilitate the application of intervention strategies reducing antimicrobial use.
