Abstract

- The objective of this trial was to investigate the potential benefits of enzyme and probiotic supplementation on the growth performance, nutrient digestibility, carcass traits, and meat quality of Simmental cattle. Sixty Simmental steers (367.75±4.69 kg) were randomly divided into three groups: control (fed basal diet), BC1 group (fed basal diet and 10 g/d brewer’s yeast and cellulase supplementation per cattle), and BC2 group (fed basal diet and 20 g/d brewer’s yeast and cellulase supplementation per cattle). A 10-d preparation period was followed by a 120-d experimental period. The results showed that the final weight of the BC2 group was greater than that of the control group. Also, feed conversion ratio of the BC2 group was better than that of the control group. Net meat weight increased by 3.86% in the BC2 group compared with the control group. The apparent digestibility of neutral detergent fiber, acid detergent fiber, and crude protein of the BC2 group was greater than that of the control group. Dietary supplementation with brewer’s yeast and cellulase supplementation could improve the growth performance and nutrient digestibility of Simmental cattle

饲粮添加酶和益生菌对西门塔尔肉牛生长性能、营养物质消化率、胴体性状和肉品质的影响

本试验旨在探讨饲粮中添加酶和益生菌对西门塔尔牛生长性能、营养物质消化率、胴体性状和肉品质的潜在益处。选取体重(367.75±4.69 kg)的西芒特阉牛60头，随机分为3组:对照组(饲喂基础饲粮)、BC1组(饲喂基础饲粮，每头牛添加10 g/d啤酒酵母和纤维素酶)和BC2组(饲喂基础饲粮，每头牛添加20 g/d啤酒酵母和纤维素酶)。预试期10 d，正试期120 d。结果表明，BC2组的最终体重大于对照组。同时，BC2组的饲料系数优于对照组。与对照组相比，BC2组净肉重提高了3.86%。BC2组中性洗涤纤维、酸性洗涤纤维和粗蛋白质的表观消化率均大于对照组。饲粮中添加啤酒酵母和纤维素酶可提高西门塔尔牛的生长性能和营养物质消化率
