Desempenho produtivo de codornas de corte alimentadas com farinha de casca de sururu em substituição ao calcário calcítico.

Abstract

This research proposed to evaluate the utilization of the flour of the sururu bark as an alternative source of calcium on the productive performance of cut quails. Four hundred one-day, unsexed European quails housed in galvanized wire battery cages were used. The light program adopted was 24 hours of light per day, using fluorescent lamps of 40 w. The experimental design was completely randomized, consisting of 5 treatments and 8 replicates, with 10 birds per experimental unit. The experimental rations were formulated with corn and soybean meal, following the nutritional recommendations for the breeding and rearing phases of Japanese quail, recommended by Rostagno et al. (2011). The treatments consisted of T1 - basal diet with 100% calcitic limestone; the others were replaced by flour of the sururu bark at levels 25, 50, 75 and 100%. The variables analyzed were feed intake, weight gain and feed conversion in the period from 1 to 35 days of age. There were no significant statistical differences (P> 0.05) for the indices of productive performance. The use of the flour of the sururu bark did not jeopardize the performance of the quail in the period of one to 35 days of age, so the flour of the sururu bark becomes an alternative to replace the total calcitic limestone.
