ABSTRACT The objective was to evaluate the addition of antibiotic growth promoters to free-choice mineral supplement on ingestive behavior, mineral intake, and growth performance of grazing bulls. Sixty Nellore bulls [initial body weight (BW) of 219±17.8 kg and 15±2 months of age] were divided in 12 marandu grass paddocks. The treatments were: mineral supplement (control), mineral supplement + virginiamycin (VIRG), mineral supplement + lasalocid sodium (LASA) and mineral supplement + salinomycin sodium (SALI). Mineral supplements were formulated with target intake […]

This trial was carried out in Luiziana, Northwest of Paraná, from June to October 2000. Twenty-four animals with 223 kg of initial body weight and nine months old, from two different genetic groups, ½ Red Angus ½ Nellore (15) and ½ Marchigiana ½ Nellore (9), were used. Animal performance was evaluated, under grazing conditions of Coastcross (Cynodon dactylon (L.) Pers) and three types of supplementation: grazing Oat + Ryegrass pasture (OR) for four hours/day; 1.2% of body weight (BW) supplement […]
