【摘要】：为研究竹酢粉对妊娠后期母羊血液生化、免疫与抗氧化指标及常乳成分的影响,选用初产、妊娠约120 d的健康妊娠后期湖羊10只,随机分为2组,分别饲喂基础日粮(对照组)和基础日粮+2%竹酢粉(试验组),试验期14 d(预饲期7 d和正式试验期7 d)。结果显示:竹酢粉极显著降低了妊娠后期母羊的血小板数量(P001),显著提高了血清谷丙转氨酶(ALT)活性(P005)和显著减低了谷草转氨酶(AST)活性、总胆固醇(TC)浓度(P005),具有提高红细胞数量、血红蛋白和总蛋白(TP)含量趋势;与对照组相比,试验组妊娠后期母羊血清总抗氧化力(T-AOC)显著降低(P005),IgA含量极显著降低(P001),IgM含量则显著升高(P005),IgG含量高于对照组;试验组母羊的乳脂率、乳蛋白率、乳总固形物和乳中尿素氮含量均低于对照组,乳糖则高于对照组,但两组间无显著差异。结果表明,日粮中添加竹酢粉能够改善妊娠后期湖羊的血液指标和提高母羊的免疫性能,但对母羊的常乳成分影响不大。
[Abstract]:In order to study the effects of bamboo powder on blood biochemistry, immune and antioxidation indexes and milk composition of later pregnant ewe, 10 Hu sheep were randomly divided into 2 groups. Basal diet (control group) and basal diet 2% bamboo baking powder (trial group) were fed for 14 days (prefeeding period 7 days and formal trial period 7 d).), respectively. The results showed that bamboo powder significantly decreased the platelet count (P001), increased the (ALT) activity of serum alanine aminotransferase (P005) and significantly decreased the (AST) activity of glutamic oxaloacetic transaminase (AST). The concentration of total cholesterol (TC) (P005) showed a tendency to increase the number of red blood cells, hemoglobin and total protein (TP). Compared with the control group, the serum total antioxidant capacity (T-AOC) was significantly decreased (P005), IgA content was significantly decreased, P001), IgM content was significantly increased (P005), IgG content was higher than that of the control group) in the later trimester of pregnancy. The milk fat percentage, milk protein rate, milk solids and urea nitrogen content in milk of the test group were lower than those of the control group, but lactose was higher than the control group, but there was no significant difference between the two groups. The results showed that the diet supplemented with bamboo powder could improve the blood index and immune performance of ewe, but had little effect on the normal milk composition of ewe.
