摘要:

本试验旨在探究负离子中药复合制剂对育肥后期延边黄牛生长性能、养分表观消化率及血液生化指标的影响。试验选取30月龄左右的延边黄牛公牛12头,体重平均为(351±20) kg,完全随机分为对照组和试验组,每组6头。其中对照组饲喂育肥后期基础日粮,试验组饲喂育肥后期基础日粮添加20 mg/kg负离子中药复合制剂。预饲期10 d,正试期90 d。试验期间,每天记录试验牛的采食量及剩余量,并在预饲期结束和屠宰前空腹称重;试验结束时空腹采血,测定血液常规生化指标;在试验第90天时采用全收粪法测定牛的表观消化率。结果显示,与对照组相比,试验组牛平均日增重(ADG)、饲料转化率(FCR)及粗蛋白质、粗脂肪、粗纤维的表观消化率,均显著高于对照组(P<0.05),干物质(DM)、粗灰分、钙、磷的表观消化率无显著变化(P>0.05);负离子中药复合制剂可以显著提高牛血液中白细胞(WBC)、淋巴细胞数(LYM)及淋巴细胞百分比(P<0.05),对血液中其他成分无显著影响(P>0.05)。综上所述,在育肥后期添加20 mg/kg负离子中药复合制剂可以显著提高延边黄牛的生长性能及对营养物质的吸收利用,并有助于延边黄牛免疫能力的提高。

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.
