摘要
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

这项工作的目的是评估在饲养场的性能包括合生元与莫能菌素钠质的，胴体品质和肉质安格斯杂交母牛的效果一个完全随机区组设计与64动物分布在四个处理进行：控制，没有补充饮食;补充合生元的饮食;与莫能菌素钠质的饮食;与合生元与莫能菌素钠质饮食与莫能菌素钠质与合生元的饮食和莫能菌素钠质的饮食增加日增重和总增重，除了改善动物饲料和生物效率相比，控制与合生元treatmentThe饮食，钠质与莫能菌素，并用合生元和苏打莫能降低干物质摄取量，并在肉增加肋圆角重量（noix）和总脂质浓度与合生元饮食促进相比，控制在安格斯杂交小母牛的饮食treatmentThe列入合生元的，有或无钠质莫能菌素，肉的剪切力的降低，提高了育肥动物性能和肉的一些物理化学特性
