Inclusão do resíduo de goiaba na alimentação de codornas de corte

Abstract

The objective was to evaluate the effects of the inclusion of guava residue in the diet of beef quails on productive performance and economic viability. A total of 250 one-day-old European quails, non-sexed, housed in battery-type galvanized wire cages were used. The light program adopted was continuous through artificial heating using 40-watt incandescent lamps and a heater. The design used was completely randomized, with 5 treatments and 5 replications, with 10 birds per experimental unit. The experimental diets were formulated based on corn and soybean meal, following the nutritional recommendations for the rearing and rearing phases of Japanese quails, recommended by Rostagno et al. (2011). The treatments consisted of: 4 levels of inclusion (0.0; 3.0; 6.0; 9.0 and 12.0%) of guava residue. To evaluate the productive performance: The rations supplied, the leftovers and the quails, were weighed, weekly. The economic analysis was performed as a function of the variations in live weight, feed consumption and feed costs, which occurred between the levels evaluated. The weekly values of feed intake, weight gain and feed conversion were not influenced (P>0.05) by the different levels of inclusion of guava pulp residue. The 3% level showed the highest financial return. It is possible to include guava pulp residue in the diet of meat quails at a level of 3%, without compromising production performance, obtaining greater economic viability.
