【摘要】：试验旨在研究饲喂发酵棉粕对安格斯肉牛生长性能和血清生化指标的影响。试验选用10月龄健康初始体重[(259.11±22.62)kg]无明显差异的黑安格斯肉牛(公牛)18头,随机分成两组(每组9头),即试验组和对照组。试验组添加6%的发酵棉粕,对照组添加6%的未发酵棉粕。试验期共42 d,预饲期10 d,正饲期32 d。试验结果表明:(1)试验组平均日增重和平均日采食量与对照组相比较有明显的差异(P0.05),相较于对照组,试验组平均日采食量提高了31.51%(P0.05),平均日采食量提高了9.1%(P0.05);对照组与试验组的料重比相比有极显著差异,和对照组相比料重比下降了16.58%(P0.01)。(2)对照组和试验组血清中总蛋白、尿素氮、钙、磷、铁、免疫球蛋白A等含量均差异不显著(P0.05)。血清中总蛋白、葡萄糖及免疫球蛋白G含量,试验组相较于对照组有显著差异,分别提高36.64%(P0.01)、37.5%(P0.01)和36.99%(P0.05)。因此,饲喂发酵棉粕可改善安格斯肉牛的生长性能。
[Abstract]:The purpose of this study was to study the effects of fermented cottonseed meal on growth performance and serum biochemical indexes of Angus Beef cattle.In the experiment, 18 black Angus beef cattle (18 bulls) were randomly divided into two groups (9 in each group, namely the experimental group and the control group). There was no significant difference in the initial body weight of 10 months old (259.11 卤22.62)kg) in the black Angus beef cattle (18 bulls).The experimental group added 6% fermented cottonseed meal and the control group added 6% unfermented cottonseed meal.The trial period was 42 days, the prefeeding period was 10 days and the positive feeding period was 32 days.The results showed that the average daily gain (ADG) and average daily feed intake (ADFI) of the test group were significantly different from those of the control group (P 0.05), compared with the control group.The average daily intake of the test group was increased by 31.51% and the average daily feed intake increased by 9.1% P0.050.The ratio of feed to weight of the control group and the experimental group was significantly different, and the ratio of feed to weight decreased 16.58% P0.01n. 2) the total protein, urea nitrogen, calcium in the serum of the control group and the experimental group were decreased by 16.58% P0.01N, and the total protein, urea nitrogen and calcium in the serum of the control group and the experimental group were decreased by 16.58% and 16.58% respectively.There was no significant difference in P, Fe and immunoglobulin A contents.The contents of total protein, glucose and immunoglobulin G in the serum of the test group were significantly higher than those in the control group, and the contents of total protein, glucose and immunoglobulin G in the serum were increased by 36.64 and 36.99, respectively, and the contents of the total protein, glucose and immunoglobulin G were increased by 36.64 and 36.99, respectively.Therefore, feeding fermented cottonseed meal can improve the growth performance of Angus beef cattle.
