Abstract:

The experiment was aimed to study the effect of compound preparations of negative ion and Chinese medicine on indexes of growth performance,nutrient apparent digestibility and blood biochemical of Yanbian Yellow cattle.Twelve thirty-month Yanbian Yellow cattle with body weights of (351±20) kg were selected and divided into control and test groups randomly.The cattler in control group were fed the basal diet,and in test group were fed the basal diet added with 20 mg/kg compound negative ion and Chinese medicine.The experimental period was 100 d,including preliminary trial period for 10 d and trial period for 90 d.During the experimental period,feed consumption and residue were recorded accurately.The cattle were weighed at the end of the preliminary trial and before slaughter.At the end of the test,the blood samples were colleted without feeding to measure the routine biochemical indexes.The nutrients apparent digestibility of cattle were measured using total collection method at day 90 of the test.The results showed that,compared with the control group,the ADG,FCR and the apparent digestibilities of CP,EE and CF of the cattle in test group increased significantly (P<0.05),while the apparent digestibilities of DM,crude ash,Ca and P had no significant change (P>0.05).The blood WBC and LYM count,LYM% increased signicantly (P<0.05),but other indexes in blood had no significant difference(P>0.05).In conclusion,adding compound preparations of negative ion and Chinese medicine could improve the growth performance,nutrient absorption and immunity of Yanbian Yellow cattle in the latter finishing period.

Key words: compound preparations of negative ion and Chinese medicine; Yanbian Yellow cattle; growth performance; nutrient apparent digestibility; blood biochemical index
