Effect of different rationale compositions on the performance of certain attributes on the Vencov, Hubbard and Croiler breeds

Abstract

An experiment was conducted to evaluate the impact of different rationale on the performance of certain attributes of Vencov, Hubbard and Croiler breeds. The average feed intake, body weight, weight gain, feed conversion efficiency, weight gain at slaughter and dressing weight was evaluated. The average feed intake were 2.18, 2.02 and 2.03 kg/bird, in the treatments (Ist, IInd and IIIrd) and it was 1.89, 1.76 and 2.57 kg/bird in the breeds (Vencov, Hubbard and Croilers) respectively. The average body weight was 1.07, 1.15 and 1.08 kg/bird, in the treatments and it was 1.10, 1.09 and 1.08 kg/bird in the breeds, respectively. The average body weight gain was 1.02, 1.09 and 1.04 kg/bird in the treatments and 1.06, 1.05 and 1.04 kg/bird, in the breeds respectively. The average feed conversion efficiency was statistically significant in the treatments. The differences in the average feed conversion efficiency among the groups B1, B2 and B3 were also very high (p
