DocumentFarm Gate Trade Patterns and Trade at Live Poultry Markets Supplying Ha Noi: Results of a Rapid Rural Appraisal
Pro-Poor Livestock Policy Initiative: A Living from Livestock
2007Also available in:
No results found.Several waves of HPAI caused by the H5N1 strain have swept through Viet Nam over the past three years and Vietnamese authorities have plans to restructure the poultry industry. These plans are costly, likely to have negative impacts on smallholder producers and will not necessarily achieve the desired objective of eliminating HPAI from Viet Nam. As an alternative, FAO’s PPLPI aims to assess mechanisms designed to overcome serious incentive problems for product quality improvement, reducing disea se and food safety risks, while increasing smallholder incomes and reducing public expenditure for conventional surveillance and control measures. In particular, we want to explore the potential of the demand side of the poultry market to achieve higher food safety standards, thereby displacing costly and often inefficient government intervention. -
DocumentPoultry Supply Chains and Market Failures in Northern Viet Nam
Pro-Poor Livestock Policy Initiative: A Living from Livestock
2008Also available in:
No results found.Our farm surveys as well as other research in Viet Nam indicate that poultry production is important for the incomes of the rural poor and it is important to recognize that the poor are involved in all stages of the poultry market chain, not just in production. Poultry market channels in northern Viet Nam might be generalized into two or three major avenues: in one small scale farmers produce local chicken and sell to nearby markets or to urban areas through informal channels. In another, medium and large farms sell through formal, regulated channels such as wholesale markets. In a few cases, large companies have built their own slaughterhouses, nearing complete vertical integration. These poultry markets are at a critical juncture. The newer, more formal marketing chains are considered to be easier to regulate, however, if smallholders and / or small-scale traders cannot market local chicken through these channels, they will continue using informal channels due to the high levels of d emand for the local type of chicken in Ha Noi. -
DocumentCommune-level Simulation Model of HPAI H5N1 Poultry Infection and Control in Viet Nam
Pro-Poor Livestock Policy Initiative: A Living from Livestock
2006Also available in:
No results found.This report describes a farm-based disease transmission model that approximates the dynamics of HPAI H5N1 outbreaks in Vietnam poultry farms. During model experimentation the impact of varying different sets of epidemiological parameters on the number of infected farms, the force of infection and on the net reproductive number within a commune were simulated. The average net reproductive number (secondary cases arising from one infected farm in a vaccinated population), Rn, in the most lenient c ontrol scenario was 2.26. Current disease control measures are predicted to significantly reduce disease transmission but do not completely eliminate the possibility for circulation of residual infection (Rn. = 1.05). A disease control optimization process which takes into account the differences in farm structure between geographical regions shows that optimal disease control policies differ, depending on local conditions. However, they also suggest that complete elimination of HPAI H5N1 from d omestic poultry in Vietnam requires high levels of vaccination coverage of S4 backyard farms, levels that are unlikely to be achievable. Therefore, more attention must be paid to early detection of infection and reduced response time.
