乳香酸在乳仔猪生产中应用效果研究

On the Application Effects of Lactic Acid in the Production of Piglets

采用６９头哺乳仔猪，研究了日粮中添加乳香酸对生长性能的影响，并与进口同类产品作了比较。结果表明：哺乳仔猪日粮中添加乳香酸后，２１、４２日龄个体重比对照仔猪分别提高９６４％和１２０９％；０～２１、２１～４２和０～４２日龄日增重各比对照提高１１６８％、１５０６％和１３５６％；仔猪腹泻头次大为减少（２∶１２），料重比改善１３１％，比较经济效益增加１６２８％。结果还表明，乳香酸在哺乳仔猪的效果要优于同类进口产品德卡肥。

The effects of lactic acid on the piglets′ performance were studied with 69 piglets fed the ration containing lactic acid. The results showed that the body weight of the piglets at day age of 21 and 42 was improved by 9.64% and 12.09% , the daily weight gain of the piglets at day age of 0～21, 21～42 and 0～42 was increased respectivelly by 11.68%, 15.06% and 13.56% comparing with the control groups after feeding the ration including lactic acid. However the numbers of diarrhoea were decreased greatly (2∶12), the feed conversion rate was improved by 13.1%, and economic efficiency was improved by 16.28%. So the effects of lactic acid for the piglets were better than those of the similar imported products.
