摘要
试验选用体重30kg左右的杜长大三元杂交猪64头,分为4个处理,每个处理4个重复,每个重复4头猪,分别饲喂含共轭亚油酸(CLA)0%,0.25%,0.5%,0.75%的日粮。试验期为60d。试验结果表明:各试验组猪的日增重、料肉比与对照组相比差异均不显著(P>0.05);添加共轭亚油酸0.5%组与对照组的背膘厚差异显著(P<0.05);随着CLA添加水平的提高,生长猪血液中总胆固醇(CHO)含量、低密度脂蛋白(LDL)含量显著降低(P<0.05),而血液中高密度脂蛋白(HDL)含量、上清液胆固醇含量和HDL与LDL比值差异不显著(P>0.05)。
To study effects of conjugated linoleic acid on the performance and the content of blood fat in growing pig,64 Duroc×Landrace×Large pigs with body weight 30 kg were randomly divided into 4 treatment groups,which had the same feeding condition and nutritional level and each group included 4 replicates,each with 4 pigs;The trial period was 60 days.Each group was fed basal diet contained 0 %,0.25 %,0.5 % and 0.75 % conjuguted linoleic acid （CLA）respectively. The results indicated that：There were no significant differences between treatments and the control group in average daily gain （ADG） and the ratio of feed to gain F/G （P 〉 0.05 ）.With the increasing level of CLA the content of cholesterol （CHO） and low density lipoprotein （LDL） of growing pigs in blood were significantly decreased （P 〈 0.05）.There were no differences in the contents of high density lipoprotein （HDL） and cholesterol in supernatant fluid and the value of HDL/LDL（P 〉 0.05）.
