【摘要】：为了研究黄芪多糖缓解肉牛短途运输应激的效果,选择15头(12月龄、体重250kg左右)健康西门塔尔杂交肉牛,随机分至对照组、运输应激组和黄芪多糖处理组中,每组5头牛,黄芪多糖处理组牛给予10g/(d·头)的黄芪多糖,运输应激组和黄芪多糖处理组进行3h的60km/h模拟公路运输。运输前1d及运输后1、7d采集所有试验牛的血样,测定相关生化指标,同时统计肉牛日增重和发病率。结果表明,运输应激组肉牛血清Na+在运输后1d显著升高(P0.05),对照组和黄芪多糖处理组在试验期间各时间点血清Na+、K+、Ca2+和Cl-无显著差异(P0.05);运输应激组在运输后1、7d的Na+/K+-ATP酶活性均极显著低于运输前1d(P0.01),血清SOD活性、GSH-Px活性均显著低于运输前1d(P0.05),运输后1、7d血清MDA含量均显著高于运输前1d(P0.05),对照组和黄芪多糖处理组上述指标在试验期间均无显著变化(P0.05);对照组和黄芪多糖处理组运输后7d平均日增重均极显著高于运输应激组(P0.01),黄芪多糖处理组的呼吸道和消化道发病率均低于运输应激组。综上,黄芪多糖对肉牛短途运输应激防治具有一定的应用价值。
[Abstract]:In order to study the effect of Astragalus Polysaccharides on alleviating the short haul stress of beef cattle, 15 healthy Simmental crossbred beef cattle were selected and randomly divided into control group. In the transport stress group and astragalus polysaccharide treatment group, 5 cows in each group and astragalus polysaccharides treated group cattle were given Astragalus Polysaccharides in 10g/ (D head), and the transport stress group and Astragalus were more than that of Astragalus. The sugar treatment group carried out the 60km/h simulated highway transportation of 3H. Before transportation, 1D and 1,7d after transportation were used to collect all the blood samples of the test cattle and determine the biochemical indexes, and the daily weight gain and incidence of beef cattle were also measured. The results showed that the Na+ of beef serum in the transport stress group increased significantly after transport (P0.05), and the control group and the astragalus polysaccharide treatment group were in the test period. There was no significant difference in serum Na+, K+, Ca2+ and Cl- at the time point (P0.05). The Na+/K+-ATP enzyme activity of 1,7d in the transport stress group was significantly lower than that before transport 1D (P0.01), the activity of SOD and GSH-Px activity were significantly lower than that before transportation. The average daily weight gain of 7D in the control group and astragalus polysaccharide treatment group was significantly higher than that in the transport stress group (P0.01), and the incidence of respiratory and digestive tract in the astragalus polysaccharide treatment group was lower than that in the transport stress group. The value of application.
