中文摘要：试验旨在研究日粮中添加菊粉对断奶羔羊生长性能、屠宰性能、器官指数、肉品质的影响。选取24只60日龄体况相似的雷州山羊羔羊,并随机分成4组:对照组(基础日粮,C组)、试验Ⅰ组(基础日粮+0.1%菊粉)、试验Ⅱ组(基础日粮+0.3%菊粉)、试验Ⅲ组(基础日粮+0.5%菊粉),每组6个重复,每个重复1只羊。预试期7 d和正式期40 d。试验结果显示:①与C组相比,试验Ⅱ、Ⅲ组料重比(FCR)显著降低(P<0.05);试验Ⅱ组的平均日增重(ADG)和平均日采食量(ADFI)均显著增加(P<0.05)。②试验Ⅱ组胴体重量和试验Ⅲ组屠宰率相比于C组显著升高(P<0.05);试验Ⅰ、Ⅱ、Ⅲ组GR值相比C组显著升高(P<0.05),但Ⅰ、Ⅱ、Ⅲ组间GR值差异不显著(P>0.05)。③试验Ⅲ组脾脏质量显著高于C组(P<0.05),其他各组间器官指数差异均不显著(P>0.05)。④试验Ⅰ、Ⅱ、Ⅲ组剪切力均显著低于C组(P<0.05),试验Ⅰ、Ⅱ、Ⅲ组pH1h之间无显著差异(P>0.05),但Ⅰ、Ⅱ、Ⅲ组pH1h相比较C组差异显著(P<0.05);试验Ⅲ组蒸煮损失显著低于C组(P<0.05);其他各组间羊肉pH24h、亮度(L*)、红度(a*)、黄度(b*)差异均不显著(P>0.05)。综上所述,在日粮中添加菊粉能够提高断奶羔羊生长性能和屠宰性能,降低料重比,脾脏指数呈上升趋势,改善了肉品质。本试验条件下,日粮中菊粉的适宜添加量为0.3%。

外文摘要：The experiments were conducted to study the effects of dietary inulin supplementation on growth performance,slaughter performance,organ index and meat quality of weaned lambs.Thirty 60-day-old Leizhou goat lambs with similar body condition were randomly divided into 4 groups:control group(basic diet),trial groupⅠ(basic diet+0.1%inulin),trial groupⅡ(basic diet+0.3%inulin)and trial groupⅢ(basic diet+0.5%inulin)with 6 replicates per group and 1 sheep per replicate.The pre-test period lasted for 7 days and the formal period for 40 days.The test results showed as follows:①compared with group C,the ratio of feed to gain(FCR)in test groupsⅡandⅢwas significantly decreased(P<0.05);The average daily gain(ADG)and average daily feed intake(ADFI)in trial groupⅡwere significantly increased(P<0.05).②The carcass weight of trial groupⅡand slaughter rate of trial groupⅢwere significantly increased compared with group C(P<0.05);the GR value of trial groupsⅠ,ⅡandⅢwas significantly higher than that of group C(P<0.05),but there was no significant difference in GR value among groupsⅠ,ⅡandⅢ(P>0.05).③Spleen mass in test groupⅢwas significantly higher than that in group C(P<0.05),but no significant difference was found in organ index among other groups(P>0.05).④The shear force of test groupsⅠ,ⅡandⅢwas significantly lower than that of group C(P<0.05),and there was no significant difference in pH1h of test groupsⅠ,ⅡandⅢ(P>0.05),but there was a significant difference compared with group C(P<0.05).The cooking loss in test groupⅢwas significantly lower than that in group C(P<0.05).There were no significant differences in pH24h,brightness L*,redness a*and yellowness b*among other groups(P>0.05).In conclusion,adding inulin to the diet can improve the growth performance and slaughter performance of weaned lambs,reduce the feed to gain ratio,increase the spleen index and improve the meat quality.Under the conditions of this experiment,the appropriate dosage of inulin in the diet was 0.3%.
