Costs of biosecurity measures in Brazilian laying hens farms in response to policies against Avian Influenza, Newcastle Disease and Salmonellosis

Abstract

SUMMARY The objective of this study was to estimate costs for egg production and for implementation of biosecurity measures described by Normative Instructions No. 56/2007, No. 59/2009, No. 36/2012 and No. 10/2013 on production costs in these establishments. To attend the “National Avian Health Program” and the “National Plan for the Prevention of Avian Influenza and Control and Prevention of Newcastle Disease”, the Brazilian Ministry of Agriculture published a series of legal acts to establish the “Procedures for Register, Inspection and Control of Breeding and Commercial Avian Establishments” intensifying the measures for prevention of high economic impact illnesses in avian flocks of the country. The adaptations comprise items of structure and biosecurity procedures that aim to increase the level of isolation of the birds to maintain them with the best health status as possible. These adaptations can result in more expenses and dedication from the producers. Thus, production costs were obtained through personal interviews with 10 voluntary commercial farmers of laying hens in Limeira region, Sao Paulo State, Brazil, between June and July, 2013. The result of this study suggests that the implementation of biosecurity measures has relatively low costs when compared to the possible risks of diseases outbreaks and the consequent economic losses that justify the adoption of these practices.

Demanda por ovos produzidos em sistemas livres de gaiolas: motivação, estratégias e estruturas de governança

“…A empresa não espera que os fornecedores atuais sejam capazes de suprir a demanda de ovos produzidos em sistemas livres de gaiolas após a transição total da empresa, porém há a expectativa de que esses fornecedores também mudem seus sistemas para se adequar à nova demanda. Por outro lado, Lagatta & Gameiro (2017) entrevistaram 28 estabelecimentos produtores de ovos do interior do estado de São Paulo e todos os proprietários afirmaram que não adequariam suas instalações às normas de bem-estar estabelecidas na Diretiva n o 74, de 1999, da União Europeia, a menos que se estabelecesse algum tipo de bônus sobre a venda do produto.…”

Individual, household and environmental factors associated with arboviruses in rural human populations, Brazil

“…Few studies describe factors associated with arboviruses in sylvatic and rural areas of Brazil. Most information regarding risk comes from studies performed in large cities (Lagatta & Gameiro, 2017;Saba et al, 2014;Tauro et al, 2019), such as the capital of Bahia state, Salvador, where the lifestyle and habits are completely different than those of people in the current study.…”
