Desempenho produtivo e rendimento de carcaça de frangos de corte de dois criadores integrados da Higest no ano de 2023

Abstract

This work, which culminated studies, was developed within the scope of the Bachelor's Degree in Animal Science and Technology at the Faculty of Veterinary Medicine. The internship took place in two production units of integrated breeders of the company Higest Moçambique Limitada, in the districts of Matutuíne and Katembe in the province of Maputo and lasted 3 months. During this period, several poultry management activities were carried out, from cleaning the facilities to monitoring the health and performance of the birds, including the collection of sample data. The chicks used were 1-day-old, unsexed chicks of the Ross 308 line, and the productive performance was evaluated based on several parameters, including the productive efficiency index, which was 266, 237 and 447 for pavilions A, B and C, respectively. In the case study, the research consisted of a retrospective analysis of the 7 cycles produced in 2023. The birds were raised in three pavilions, with pavilion A belonging to the Matutuíne breeder and pavilions B and C belonging to the Katembe breeder. The pavilions presented different structural and management conditions, such as heating system, types of feeders and drinkers. From the analysis carried out at 28 days, the results showed that the live weight of the birds in pavilions A, B and C was 1358.87 g, 1267.64 g and 1569.47 g, respectively; the feed conversion (FCR) was 1.67, 1.57 and 1.53 for pavilions A, B and C, respectively; the viability (V) was 93.7% in pavilion A, 96.45% in pavilion B and 97.35% in pavilion C; the accumulated feed intake (CR) was 2374.34 g in pavilion A, 2132.71 g in pavilion B and 2289.82 g in pavilion C; and the productive efficiency index (PEI) was 282, 300 and 317 for pavilions A, B and C, respectively. On the other hand, the carcass yield (CR) was 77.6% in pavilion A, 76.91% in pavilion B and 97.35% in pavilion C. The comparison between the pavilions did not reveal statistically significant differences (p> 0.05) in the evaluated indicators, indicating a similar performance among the breeders.(TRADUÇAO NOSSA)
