摘要
将90头28 d断奶的"杜×长×大"三元杂交仔猪,随机分成3组,每组3个重复,每个重复10头,研究外源核苷酸混合物对断奶仔猪生长性能和抗氧化功能的影响。2个试验组在对照组的基础上分别添加0.15%、0.25%的核苷酸混合物。发现在基础日粮中添加0.25%的核苷酸有提高仔猪日增重、日采食量和降低料重比的趋势,显著降低了仔猪腹泻频率(P<0.05);有提高仔猪第14 dSOD、T-AOC和CAT活性的作用(P<0.05),显著降低了仔猪第7 d和第14 d仔猪血清中MDA含量(P<0.05)。结果表明,在断奶仔猪日粮中添加0.25%的核苷酸混合物有提高仔猪生长性能的趋势,并可显著提高仔猪的抗氧化功能。
90 piglets (Duroc x Landrace x Large white) weaned at 28^th day were used to study the effect of exogenous nucleotides compound on the growth performance and antioxidant function in weaned piglets. The piglets were allotted randomly into three groups, each group had 3 replicates of 10 piglets. The experimental groups were fed with the basal diet supplemented with 0.15% and 0.25% exogenous nucleotides compound respectively. Compared to the control group, there was a tendency to increase average daily gain, daily feed intake and decrease feed conversion efficiency by 0.25% exogenous nucleotides compound supplementation in diet( P 〉 0.05 ) , diarrhea frequency was significantly decreased ( P 〈 0.05 ). SOD, T - AOC and CAT activity at 14^th day were significantly increased(P 〈0.05) ,content of MDA at 7^th and 14^th day were significantly decreased ( P 〈 0.05 ). The result indicated that could increase growth performance and improve the antioxidant function significantly by 0.25% the addition of 0.25% exogenous nucleotides compoud supplementation indict.
