DESEMPENHO E RENDIMENTO DE CARCAÇA DE FRANGO DE CORTE DE CRESCIMENTO LENTO ALIMENTADOS COM FARELO DE PALMA FORRAGEIRA

Abstract

Poultry farming is an internationalized and uniform economic activity without geographical borders, generating a great impact on the Brazilian economy. Numerous studies seek the implementation of foods with lower production cost aiming to reduce feed costs without decreasing performance and carcass yield. The objective of this research was to evaluate the use of forage palm meal in the feeding of slow growing broilers. The experiment was conducted at the Poultry Industry Department of the Federal University of Cariri, from September 18 to December 12, 2018 (slaughtered at 85 days old). We purchased 200 nonsexed chicks of the heavy, one day old red line. From 1 to 27 days of age, all chicks were free to receive initial ration sold at the local trade appropriate for free-range chickens. When the chickens were 27 days old, they were weighed and distributed in a completely randomized design with three treatments (control diet, 5% bran diet, and 10% palm bran diet) and five replications of 10 units each, totaling 50 treatments. birds by treatment. The birds that received diet containing 90% of feed and 10% of forage palm presented lower food intake. However, the feed conversion of these chickens did not differ significantly from commercial feed only. The variables breast, thigh + (plus) thigh, breast and heart showed no statistically significant difference while the carcass, liver and gizzard variables differed by the test. SNK (P <0.05) Palm bran can be used to feed slow growing broilers up to the 10% level.
