Influência do consumo de ração pré alojamento e distância de transporte até a granja no desempenho de frangos de corte

Abstract

One of the key points for the zootechnical development of broiler chickens is the weight gain on the first week of life, where the bird could gain up to 4.5 times its first day weight, and this factor will influence positively all other zootechnical indexes like food conversion, daily weight gain and mortality. The objective of this homework was to study if there is influence of pre-housing feed consumption of broiler chickens, during transport until arrival at the farm, zootechnical performance e broiler chickens mortality. The birds received commercial feed at the hatchery and the batches were housed from March to May 2023 and from November 2023 to January 2024. Weighing and consumption assessments were carried out, evaluating the zootechnical performances of food conversion (FC), daily weight gain (DWG) and production efficiency index (PEI). Regarding accommodation distances, properties were chosen using 3 different distance radiuses (short, medium, long), with each property receiving a repetition without a diet and a repetition with a diet, under the condition of structure and management. For the FC, DWG and PEI parameters, data from more than 130 slaughteres Ross batches were used, corresponding to 2.509.500 housed birds. The experimental delimitation utilized was the entirely casual in factorial scheme 2 x 3 the with Tukey Test and using the statistical package SAS. Results were found with a statistical difference in fed batches on the chick weight on housing, on the jowl, liver and residual egg yolk. Zootechnical differences were not found. More studies exploring other aspects of premature nutrition are necessary to advance this topic that involves economical aspects and animal welfare.
