【摘要】：为了探究棉花秸秆对育肥羊生长性能和血清生化指标的影响,为其在反刍动物中利用提供基础研究资料,试验采用单因素随机设计,将体重、年龄相近的卡拉库尔羊羔羊72只随机分为6组,对照组饲喂不含棉源的基础日粮,试验1,2,3,4,5组分别添加3%、12%、18%、27%和39%棉花秸秆,各组能量、蛋白质含量基本不变,测定羊只体重指标、血清生化指标等。结果表明:从试验全期看,试验1,3组(添加3%、18%棉花秸秆)卡拉库尔羊日增重显著高于对照组(P0.05),试验2,4,5组均低于对照组;日粮中添加≥27%棉花秸秆(试验4,5组)可使血清中丙氨酸氨基转移酶、天门冬氨酸氨基转移酶活性、尿素氮和三酰甘油含量增加,总蛋白和白蛋白含量下降,血清中钙含量降低而磷增加,钙磷比例失调,从而影响育肥效果。
[Abstract]:In order to investigate the effect of cotton straw on growth performance and serum biochemical index of fattening sheep and to provide basic research data for its use in ruminants, the experiment adopted a single factor random design to determine the weight of the sheep. 72 lambs of the same age were randomly divided into 6 groups. The control group was fed a basal diet without cotton source. The control group was fed with the basal diet without cotton source. In experiment 1, the weight of sheep was measured by adding 32% and 18% cotton straw, respectively. The energy and protein contents of each group were basically unchanged, and the body weight index of the sheep was measured. Serum biochemical indexes. The results showed that the daily gain of Karakuer sheep was significantly higher than that of the control group (P0.05), and that of the control group was lower than that of the control group (P < 0.05), and that of the control group was lower than that of the control group (P < 0.05). Dietary supplementation of cotton straw 鈮，
