摘　　要：文章旨在探究马齿苋提取物对家兔生长性能、脂质代谢及养殖效益的影响。试验选取200只健康、体重为(0.64±0.01)kg的30日龄断奶仔兔,随机分为4组,分别为对照组(饲喂基础日粮),低剂量组(基础日粮+100 mg/kg马齿苋提取物)、中剂量组(基础日粮+300 mg/kg马齿苋提取物)、高剂量组(基础日粮+500 mg/kg马齿苋提取物),每组5个重复,每个重复10只家兔,预饲验3 d,正试期42 d。结果表明:(1)日粮添加100、300、500 mg/kg马齿苋提取物后,家兔的终末体重(FBW)、平均日增重(ADG)显著高于对照组(P<0.05),料重比(F/G)均显著低于对照组(P<0.05),平均日采食量无明显差异(P>0.05)。(2)日粮添加300、500 mg/kg马齿苋提取物后,家兔血清中血清总胆固醇(TC)和甘油三酯(TG)含量显著低于对照组(P<0.05),高密度脂蛋白胆固醇(HDL-C)的含量显著高于对照组(P<0.05),添加500 mg/kg马齿苋提取物后,家兔血清中低密度脂蛋白胆固醇(LDL-C)水平显著降低(P<0.05)。(3)日粮添加100、300、500 mg/kg马齿苋提取物后,增重成本显著下降,毛利润显著升高(P<0.05)。且添加量在300 mg/kg时效果最佳。To investigate the effects of Portulaca oleracea extract on the growth performance,lipid metabolism,and economic benefits of rabbit farming,this experiment selected 200 healthy 30 days old weaned rabbits with a body weight of(0.64±0.01)kg.They were randomly divided into four groups:a control group(fed a basic diet),a low-dose group(basic diet+100 mg/kg of Portulaca oleracea extract),a medium-dose group(basic diet+300 mg/kg of Portulaca oleracea extract),and a high-dose group(basic diet+500 mg/kg of Portulaca oleracea extract),with five replicates per group and ten rabbits per replicate.After a pre-trial period of three days,the formal trial lasted for 42 days.The results demonstrated that:1)Rabbits supplemented with 100 mg/kg,300 mg/kg and 500 mg/kg of Portulaca oleracea extract showed a significant increase in final body weight(FBW)and average daily gain(ADG)compared to the control group(P<0.05),the feed-to-gain ratio(F/G)compared to the control group significant reduce(P<0.05),with no significant differences observed in the average daily feed intake(P>0.05).2)Dietary inclusion of 300 mg/kg and 500 mg/kg of Portulaca oleracea extract resulted in significantly lower serum total cholesterol(TC)and triglycerides(TG)levels,and significantly higher HDL-cholesterol(HDL-C)content in rabbits compared to the control group(P<0.05).Moreover,the addition of 500 mg/kg Portulaca oleracea extract significantly reduced serum LDL-cholesterol(LDL-C)levels(P<0.05).3)The addition of 100 mg/kg,300 mg/kg,and 500 mg/kg Portulaca oleracea extract significantly decreased the cost of weight gain and significantly increased the gross profit(P<0.05).The most effective inclusion level was found to be 300 mg/kg.
