Efeito do maneio sanitário sobre o índice de sobrevivência de frangos de corte criados na Empresa Abílio Antunes em Chimoio

Abstract

The present work aimed to evaluate the influence of sanitary management used in intensive of broiler chickens on the survival rate, in the Company Abilio Antunes. In this way, an acclimatised assisted an acclimatised pavilion populated with fifty thousand day-old chicks, cobb 500 strain, genetically modified for rapid growth, in an intensive and automatic water and feed administration system. For the determination of average daily weight gain, a randomly A 10% sample was randomly selected and weighed at the following: 14, 21 and 35 days of life. The sanitary management used in the company was analysed, and temperature, humidity and mortality data were collected and analysed. data of temperature, humidity and daily mortality in the shed. It was observed during the high humidity in the shed, high densities, shortening of the depopulation period and deficient cleaning and disinfection of the equipment and facilities, which despite a good Despite a good vaccination program, it does not save the farm from high mortality rates of 5.2% and low weight of chickens being 1416g at the end of the cycle. However, it can be concluded that the welfare parameters welfare parameters (temperature and relative humidity) associated with the use of too high stocking densities high densities, have conditioned the low growth and high mortality of chickens in this farm.

The treatment applied to the litter, associated with the short fallow period, contributes to the increase in mortality by not enabling the total elimination or the disease cycle. (TRADUÇAO NOSSA)
