【摘要】 试验选取５６头２８日龄断奶的杜长大三元杂交仔猪进行饲养对比试验和消化试验，将试验猪随机分成７组，测定棕榈油、豆油、牛油三种类型油脂在早期断奶仔猪中热能、脂肪、油酸、亚油酸、亚麻酸的可消化率。研究添加不同类型的油脂对早期断奶仔猪日粮中主要营养成份消化率及饲养效果的影响。结果表明：牛油在早期断奶仔猪中的热能表观消化率仅为棕榈油和豆油的７４．０７％和７２．４８％．单一添加油脂时，饲养试验和消化试验结果一致表明，棕榈油和豆油二者之间的试验结果无明显差异，但它们的效果显著优于牛油，饲喂棕榈油和豆油日粮的仔猪，其日增重比饲喂含牛油日粮的仔猪分别提高１７．３４％和２０．８９％．添加复合油脂时以２％豆油＋２％棕榈油组合最佳，仔猪日增重比棕榈油组提高２１．９７％，比豆油组提高１８．３８％．更多还原

【Abstract】 crossing(Duroc×Landrace×Yorkshire) piglets weaned at 28 days were selected for experiment on feed and digestion. They were divided into 7 groups so as to determine their digestibility of thermal energy fat, Oleic acid, lnferior-Oleic acid, flax Oleic acid Contained in Palmitic oil, soybean oil, and beef oil. The aim of this experiment lies in studying the effect of adding different oils to the early weaned piglets’ration nutribion and on the feeding efficiency. The result showed: the apparent digestibility of the thermal energy of beef oil only accounted for 74.07% of that of palnitic oil and 72.48% of that of soybean oil. When single oil was added the feeding and digestion experiments showed no considerable difference between adding palmitic oil and adding soybean oil, but their efficienly was much prior to that of adding beef oil. The daily gain of those piglets fed with ration Containing palmitic oil and soybean oil was 17.34% and 20.89% higher respectively than those fed with ration containing beef oil. Fed with compound oils the group fed with ration containing 2% palmitic oil + 2% soynbean oil showed the best efficiency.Their daily gain increased 21.97% higher than that of the group fed with ration containing palmitic oil and 18.38% higher than that of the soybean oil group.更多还原
