Use of bromass in broiler rations as a different protein source

Abstract

In this study, we aimed to determine the effects of modified vinasse (Bromass) on body weight, body weight gain, feed intake, feed conversion ratio, carcass yield, litter quality, blood serum parameters and broiler performance index. A total of 600 Ross-308 broiler chicks were used in the experiment, and the chickens were divided into the following 4 main groups: control (0 g/kg Bromass), group I (5 g/kg Bromass), group II (30 g/kg Bromass), and group III (60 g/kg Bmmass). Additionally, each of the main groups was divided into 10 subgroups of 15 chickens each. The trial lasted for 42 days. Supplementation with Bromass (5, 30 and 60 g/kg) caused significant (P < 0.05) increases in the average body weight, body weight gain, feed intake, feed conversion ratio, carcass weights, carcass yield and breast yields. Additionally, Bromass supplementation caused more dry litter at a significant level (P<0.05) and significant (P<0.05) decrease in serum cholesterol concentration. The addition of Bromass to the broiler diets resulted in a significant decrease in feed prices (P<0.05) and an important increase (P<0.05) in the broiler performance index values. At the end of the study, we concluded that the addition of Bromass as a different protein source, especially at the 30 g/kg level, caused positive effects and Bromass makes it possible to produce a more profitable broiler.
