复合酸化剂对断奶仔猪生产性能的影响

为研究复合酸化剂对断奶仔猪生产性能的影响,此次试验选取了40头28±2日龄杜×长×大三元杂交断奶仔猪,并将它们随机分成4个处理组。这4个处理组均饲喂基础日粮,其中,试验1、2、3组分别添加0.1%复合酸化剂、0.2%复合酸化剂、0.3%复合酸化剂,对照组不做任何处理。试验结果表明,在30d试验期内,试验组仔猪比对照组仔猪平均日增重分别提高了5.9%、13%、10.24%,其中基础日粮中添加0.2%复合添加剂的试验组与对照组日增重差异显著(P<0.05);料肉比分别下降了7%、10.21%、8.13%;并且试验组的仔猪腹泻率较之对照组有明显的下降。试验发现,日粮中添加复合酸化剂能显著改善断奶仔猪生产性能,复合酸化剂添加量为0.2%时,仔猪的生产性能最佳。

Effects of Compound Acidifier on Performance of Weaned Piglets

To investigate the effects of compound acidifier on performance of early weaned piglets,a total of 40 crossbred(Duroc×Landrace×Yorkshire)piglets weaned at 28±2 days of age were randomly allocated into 4 treatments:Control,Compound acidifier 0.1%,0.2% and 0.3%.The results showed that:Compound acidifier 0.1%,0.2%,0.3% increased average daily gain(ADG) by 5.9%,13%,10.24% respectively,besides Compound acidifier 0.2% significantly increased F/G(P0.05).Compound acidifier 0.1%,0.2%,0.3% decreased feed conversion rate by 7%,10.21%,8.13% respectively.Compared with the Control group,the diarrhea rate of the early weaned piglets decreased sharply.According to the trial,when compound acidifier was added into the diet,the performance of piglets improved a lot,and the proper amount of compound acidifier in the diet of weaned piglets may be 0.2%.
