This work was carried out to study the daily average gain (DAG) of steers grazing Brachiaria brizantha cv. Marandu, supplemented, from July to December, with two levels of three different supplements. Fifty-four Nellore steers (9 for each treatment) aged approximately 20 months and initial average live weight of 370 kg were used. The experimental treatments were: AMI – supplement rich in starch (based on corn), OLE – supplement rich in fat (based on whole cottonseed) and A+O – supplement combination […]

The objective of this work was to evaluate the performance and carcass characteristics of cattle fed high concentrate diets containing 15, 21 or 27% of sugarcane bagasse in the dry matter. Twenty-four Nellore steers with 279 kg of shrunk body weight and 24 months of age, two per pen, were fed for 98 days. No significant effects were observed for average daily gain (mean =1.461 kg) and feed efficiency among the treatments. It was observed a linear effect between dry […]
