摘要: 【目的】研究健脾消导中药复方对6月龄西门塔尔牛×本地黄牛杂交犊牛(西杂牛)生长性能、瘤胃发酵参数和血清生化指标的影响。【方法】选取体重为193 kg±20 kg的西杂牛28头,随机均分为对照组和试验组。对照组饲喂基础饲粮,试验组在基础饲粮中添加0.5%健脾消导中药复方,预试期7 d后连续饲喂90 d,于第91天晨饲前称重并采集瘤胃液和血液,测定瘤胃液短链脂肪酸和血清生理生化指标。【结果】与对照组相比,试验组平均日增重(ADG)显著增加(P<0.05),料重比(F/G)降低;瘤胃液pH、乙酸、丙酸、丁酸、总短链脂肪酸含量及乙酸/丙酸比值均无显著差异(P>0.05);血清总胆固醇(CHO)含量升高;总胆红素(TBIL)、直接胆红素(DBIL)、谷丙转氨酶(ALT)和丙二醛(MDA)含量均显著降低(P<0.05);免疫球蛋白A(IgA)、免疫球蛋白G(IgG)、胃泌素(GAS)、三碘甲状腺原氨酸(T3)、还原型谷胱甘肽(GSH)含量均显著升高(P<0.05);胃动素(MTL)和生长激素(GH)含量虽有升高但均差异不显著(P>0.05)。【结论】在6月龄西杂牛的饲粮中添加健脾消导中药复方可以调节激素分泌、促进草料消化吸收、增强抗氧化能力、提高机体免疫力,进而提升西杂牛的生长性能。

Abstract: 【Objective】 The purpose of this experiment was to find out the effects of Jianpi Xiaodao Chinese herbal compound on the growth performance,rumen fermentation parameters and serum biochemical indexes of 6-month-old Simmental cattle×local yellow cattle (Simmental crossbred cattle).【Method】 28 Simmental crossbred cattles weighing 193 kg±20 kg were selected and randomly divided into control group and experimental group respectively.The control group was fed with basal diet,and the experimental group was fed with basal diet supplemented with 0.5% Jianpi Xiaodao Chinese herbal compound.After 7 d of pretrial period,cattles were fed for 90 d.Rumen fluid and blood were collected before morning feeding on 91 d,and rumen short-chain fatty acids and blood physiological and biochemical indexes were measured.【Result】 Compared with control group,in the experimental group,the average daily gain weight (ADG) was significantly increased (P<0.05),the feed-to-gain ratio (F/G) was decreased,there were no significant differences in rumen fluid pH and contents of acetic acid,propionic acid,butyric acid,total short-chain fatty acid and ratio of acetic acid to propionic acid (P>0.05),the content of serum total cholesterol (CHO) was significantly higher,the contents of total bilirubin (TBIL),direct bilirubin (DBIL), alanine aminotransferase (ALT) and malondialdehyde (MDA) were significantly decreased (P<0.05),the contents of immunoglobulin A (IgA),immunoglobulin G (IgG),gastrin (GAS),triiodothyronine (T3) and reduced glutathione (GSH) were significantly increased (P<0.05). The contents of motilin (MTL) and growth hormone (GH) were increased but there was no significant difference (P>0.05).【Conclusion】 The supplementation of Jianpi Xiaodao Chinese herbal compound in the diet of 6-month-old Simmental crossbred cattle could regulate hormone secretion,promote forage digestion and absorption,enhance antioxidant capacity,improve body immunity,and then improve the growth performance.
