Synbiotics and sodic monensin on performance and meat quality of Angus crossbred heifers on feedlot
The objective of this work was to evaluate the effect of inclusion of synbiotics and sodic monensin on the performance, carcass characteristics, and meat quality of Angus crossbred heifers on feedlot. A completely randomized block design was carried out with 64 animals distributed in four treatments: control, a diet without supplementation; a diet supplemented with synbiotics; a diet with sodic monensin; and a diet with synbiotics and sodic monensin. The diet with sodic monensin and the diet with synbiotics and sodic monensin increased the average daily gain and total live weight gain, besides improving the feed and biological efficiency of animals compared to control treatment. The diet with synbiotics, with sodic monensin, and with synbiotics and sodic monensin decreased dry matter intake, and increased the rib fillet weight (noix) and the total lipid concentration in the meat. The diet with synbiotics facilitated the reduction of meat shear force compared to control treatment. The inclusion of synbiotics, with or without sodic monensin, in diet of Angus crossbred heifers, improves animal performance on feedlot and some physicochemical characteristics of meat.

O objetivo deste trabalho foi avaliar o efeito da inclusão de simbióticos e de monensina sódica em dietas sobre o desempenho, as características de carcaça e a qualidade da carne de novilhas mestiças Angus em confinamento. Utilizou-se um delineamento inteiramente casualizado, com 64 animais distribuídos em quatro tratamentos: controle, dieta sem suplementação; dieta suplementada com simbióticos; dieta com monensina sódica; e dieta com simbióticos e monensina sódica. A dieta com monensina sódica e a dieta com simbióticos e monensina sódica proporcionaram maior ganho de peso médio diário e ganho de peso vivo total, além de melhorar a eficiência alimentar e biológica dos animais em comparação ao controle. A dieta de simbióticos, a de monensina e a de simbióticos com monensina sódica ocasionaram a redução da ingestão de matéria seca, elevaram o peso do filé da costela e os teores de lipídeos totais na carne. A dieta com simbióticos proporcionou a redução da força de cisalhamento da carne em relação ao controle. A inclusão de simbióticos, com ou sem monensina sódica, na dieta de novilhas mestiças Angus confinadas, beneficia o desempenho animal e algumas características físico‑químicas da carne.
