Resíduo da polpa de goiaba em dietas para codornas

Abstract

The objective of this study was to evaluate the inclusion of the guava pulp residue in broiler quail diets on productive performance, carcass yield, and poultry economic viability at 42 days of age. Two hundred and fifty-one unsexed European quail were distributed in a completely randomized experimental design with five inclusion levels (0.0, 3.0, 6.0, 9.0 and 12.0%) of residue of guava, with five replicates and 10 birds per experimental unit. The variables evaluated during the experimental period were: feed intake (FI), weight gain (WG) and feed conversion (FC), carcass yield, noble cuts and edible offal. No significant differences (P> 0.05) were observed for weight gain, feed intake and feed conversion rate during 1 to 42 days of age. The absolute weights and carcass yields, noble cuts (breast, thigh and drumstick), edible offal and abdominal fat of the quails were not influenced (P> 0.05) by the inclusion levels of the guava pulp residue to the diets. The guava pulp residue can be used as an alternative ingredient in European quail diets up to 3% inclusion level without compromising yield performance, poultry carcass yield and economic viability.
