复合酸化剂对断奶仔猪生产性能的影响

摘要

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 aeidifier 0.2% significantly increased F/G (P0.O5).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%.%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。
