摘  要：
旨在探讨精氨酸(Arg)或N-氨甲酰谷氨酸(NCG)对35 d哺乳期母獭兔繁殖性能及断奶幼兔生长性能和机体抗氧化能力的影响。选取哺乳期母兔45只,随机分为5组:基础日粮组(对照组)、基础日粮+0.3%Arg组(试验Ⅰ组)、基础日粮+0.6%Arg组(试验Ⅱ组)、基础日粮+0.03%NCG组(试验Ⅲ组)、基础日粮+0.06%NCG组(试验Ⅳ组),试验期35 d;选取35 d断奶体重相近健康幼兔100只,分为5个组,饲喂日粮和母兔组一致,试验期21 d。结果表明:试验Ⅱ、Ⅳ组母兔体重出现不同程度增长,再次受胎率Ⅱ组最好;哺乳仔兔21 d、35 d个体重,试验Ⅱ、Ⅳ组显著高于对照组(P<0.05)。断奶幼兔试验中,各试验组末重、日增重均显著高于对照组(P<0.05);试验Ⅱ、Ⅲ组的日采食量显著高于对照组(P<0.05),但料重比无差异,试验Ⅰ、Ⅳ组日采食量、料重比均显著低于对照组(P<0.05)。与对照组相比,哺乳35 d的各试验组仔兔血清抗氧化指标无显著差异(P>0.05);而断奶幼兔在试验21 d时,试验Ⅲ、Ⅳ组血清SOD活力均显著高于对照组(P<0.05)。结论:日粮添加精氨酸或NCG能维持母兔体重,提高哺乳仔兔个体重,并能提高断奶后幼兔个体重、平均日增重及降低料重比,且NCG能提高断奶后幼兔的抗氧化能力。

摘  要：
This study was conducted to investigate the effects of arginine or N-carbamylglutamate(NCG) on production performance of lactation doe and growth performance,antioxidant ability of weaning rabbit.A total of 45 lactation does with similar weights were randomly divided into 5 groups.The control group was fed with basal diet,experiment group Ⅰ to Ⅳ were fed basal diet with 0.3%,0.6% Arg and 0.03%,0.06% NCG,respectively.The experiment lasted for 35 d.While,the 35 d weaned rabbits,with similar weights were randomly divided into 5 groups.The experiment diets were the same with the doe treatments.The experiment lasted for 21 d.The results showed that does' weights were significantly increased in group Ⅱ and Ⅳ.The rate of pregnancy again in group Ⅱ was the best.On 21 d and 35 d,the body weight of lactating rabbits in group Ⅱ and Ⅳ was significantly higher than that in control group(P<0.05).In weaned young rabbit experiment,the finial weight and the average daily gain(ADG) of young rabbit in each treatment group were significantly higher than that in control group(P<0.05).The average daily feed intake(ADFI) in the group Ⅱ and Ⅲ was significantly higher than that in the control group(P<0.05),but there was no significant difference in the ratio of feed to gain(F/G).And ADFI and F/G in group Ⅰ and Ⅳ were significantly low when compared with control group(P<0.05).However,no significant differences were observed in serum antioxidant ability of 35 d lactation rabbit between treatment and control group.After weaning 21 days,compared with control group,SOD activities of young rabbit serum in group Ⅲ and Ⅳ were significantly increased(P< 0.05).In conclusions,adding arginine or NCG can maintain does body weights,improve lactation rabbit body weights.At the same time,it can also improve weaning rabbit ADG and body weight at 56 d and decrease F/G.Even more,NCG can increase anti-oxidant capacity of weaned rabbits.
