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.
