中草药对仔猪生长性能和血清生化参数的影响

Effects of Chinese herbal formula on growth performance and serum biochemical parameters in weaned piglets

试验选用21日龄断奶的三元杂交(杜洛克×长白×大约克)仔猪60头,按完全区组设计分为3组,处理1饲喂添加0.2%中草药复方添加剂日粮,处理2饲喂添加0.02%硫酸粘杆菌素日粮,处理3饲喂基础日粮.饲喂一定时间后考察仔猪生长性能、腹泻指数、血清生化参数和器官指数等指标的变化.结果表明,中草药复方添加剂能提高仔猪ADG,降低F/G(P<0.05),防治断奶仔猪腹泻效果强于硫酸粘杆菌素(P<0.05);该添加剂还能提高血清TP、ALB和TCHO含量以及GOT、GPT、AMY和LPS活性,降低GLU和TG含量以及CK活性.上述结果提示,本试验所用中草药复方添加剂能够缓解仔猪断奶应激,增强机体抵抗力,促进生长.

The experiment was conducted to determine the effects of dietary additive of Chinese herbal formula on the growth performance, diarrhea index, serum biochemical parameters and peptic index in early-weaned piglets. Sixty piglets weaned at 21 days of age were randomly assigned to 3 treatment groups, representing supplementation with 0 or 2g/kg of the herbal formula or 0.2g/kg of colistin to maize- and soybean meal-based diets（ n = 20 per group）. Dietary supplementation with the formula could increase weight gain and feed efficiency（ P 〈 0.05 ）, and effectively prevent piglets from diarrhea（ P 〈 0.05 ）. Such functions of the formula were equal to or stronger than those of colistin＇ s. On day 7, the concentration of TG in the formula group was significantly lower than that in the supplement-free group（ P 〈 0.05） ; On day 14, the activity of GOT in the formula group was significantly higher than those in the colistin group（ P 〈 0.05）, and the activity of CK was lower（ P 〈 0.05）than those in the colistin group and the supplement-free group ; On day 28, the activity of AMY in the formula group was significantly higher than those in the colistin group and the supplement-free group, and of CK significantly lower than that in the colistin group （ P 〈 0.05）. Collectively, these findings indicate that the herbal formula is safe and effective in preventing the weaning-associated intestinal dysfunction and improving the growth performance in piglets.
