ABSTRACT - The present study evaluated the efects of supplementing VM in grazing cattle during the rearing phase on performance and carcass quality of beef cattle in the fnishing phase. Two experiments with a randomized block design were conducted in consecutive years to contrast two post-weaning supplementation strategies using VM at 45 mg/100 kg body weight (BW). In the frst year, treatments were protein supplement in the dry season and mineral supplement in the rainy season versus the addition of VM both in the protein and mineral supplements. In the second year, was contrasted with protein supplement in the dry season and protein-energy supplement in the rainy season. Performance, carcass traits, and carcass quality were evaluated at the end of both phases. In Year 1, adding VM in mineral supplement increased fnal backfat thickness (P=0.05), backfat gain (P=0.06), fnal rump fat thickness (P=0.02), and rump fat gain (P=0.01). In the fnishing phase, VM-treated cattle had a greater dry matter intake (P=0.03) and tended to show a greater backfat thickness than non-treated cattle (P=0.07). In Year 2, no VM efects were observed on post-weaning phase performance and carcass traits. However, cattle-fed VM during the post-weaning phase tended to show a lower feed conversion ratio (P=0.09) and had a signifcantly higher gross feed efciency (P=0.03) than non-treated cattle at slaughter. Virginiamycin supplementation during rearing on pasture improves performance and carcass fattening in the growth phase and has a residual efect in the fnishing phase that may refect greater backfat thickness and gross feed efciency.

Foi avaliada a eficiência do polietilenoglicol (PEG) e do Co-EDTA na estimativa dos principais parâmetros que caracterizam a cinética da fase líquida do rúmen em bovinos leiteiros. Não foram observadas diferenças significativas (P>0,05) entre os indicadores para estimativas de volume ruminal (l), taxa de passagem (l/h), tempo de retenção (h), taxa de fluxo (l/h) e taxa de reciclagem (ciclos/d). Entretanto, o Co-EDTA mostrou ser o indicador mais estável e preciso. Na impossibilidade de realização da espectrofotometria (metodologia de análise do Co-EDTA), o PEG surge como alternativa barata e que fornece resultados satisfatórios, desde que, seja respeitada a minuciosidade da técnica turbidimétrica. |
