Inclusão do resíduo da acerola em reações para codornas de corte

Abstract

This experiment aims to evaluate the level of inclusion of acerola residue in meat quails diet on performance, carcass yield, intestinal biometrics and economic viability of birds. The experiment was conducted in the cotton production industry of the Academic Unit Center of Agricultural Sciences UFAL. We used 400 European quails, not sexed, a day old, distributed in a completely randomized design with four levels of inclusion (0.0, 3.0, 6.0, 9.0 and 12.0%) residue acerola, with eight replicates and 10 birds per experimental unit. The birds were fed a diet based on corn and soybean meal, supplemented with vitamins and minerals, isocaloric and isoproteic presenting in its composition in 2900 kcal / kg metabolizable energy, and 22% crude protein, formulated according to the recommended nutritional requirements by Rostagno et al. (2011). There were no statistically significant differences (P> 0.05) for productive performance. As for carcass characteristics, significant differences were observed (P <0.05) in absolute and relative weights of liver and gizzard of birds at 35 days of age. The results observed at 42 days of age had no significant effect (P> 0.05) in the absolute and relative weight of the carcass yield of birds. the inclusion of up to 12% of the residue of acerola in quails feed is possible.
