Resíduo de bolacha em rações para suínos na fase de terminação

Abstract

The experiment was carried out to evaluate the effects of diets with biscuit residue in feed for pigs in the finishing phase on performance, carcass yield and meat quality. It was used 40 pigs both male and female (LM 6200 x DB 90), with of initial average weight 67, 96 kg, distributed into a design randomized block, consisting of 5 treatments and 4 replicates with 2 pigs per cage in conventional breeding shed, located in Nova Porteirinha-MG city. The evaluation period was 26 days. The treatments consisted of T1= control diet, T2= biscuit residue all diets to be isoprotein, isoenergetic, isocalcium, isophosphoric, isolisyne and isomethionine after correction of the other ingredients. The biscuit residue did not influence the final weight, daily feed intake, daily weight gain, feed conversion, carcass weight, carcass length and analyzed meat quality parameters. However the treatments influenced carcass yield, with diet with 15% biscuit residual providing the best result. It was concluded that for best results of carcass traits, the diet with 15% biscuit residual provided the best results for yield carcass.
