摘要: 【目的】研究不同比例孜然秸秆替代小麦秸秆对羔羊生长性能、屠宰性能和血浆生化指标的影响,旨在提高新疆、甘肃等地区孜然秸秆的利用率。【方法】采用单因素设计,选择体重相近的健康雄性羔羊27只,随机分为3组,用孜然秸秆分别替代0(对照组)、30%(CS1组)、60%(CS2组)小麦秸秆,饲粮其余组分相同。每组9只羔羊,单栏饲喂,预饲期15 d,正试期60 d。试验期间测定羔羊生长性能,试验结束后采血并屠宰,测定屠宰性能和血浆生化指标。【结果】①CS1和CS2组羔羊平均日采食量(ADFI)均显著高于对照组(P<0.05)。羔羊初重、末重、平均日增重(ADG)和料重比(F/G)在各组间均无显著差异(P>0.05)。②羔羊屠宰率、宰前活重、胴体重和眼肌面积在各组间均无显著差异(P>0.05)。CS1组羔羊心脏重量显著高于对照组(P<0.05)。羔羊肝脏、脾脏、肺脏和肾脏的重量及指数在各组间均无显著差异(P>0.05)。③羔羊血浆葡萄糖(GLU)、甘油三酯(TG)、总胆固醇(TC)、总蛋白(TP)、球蛋白(GLB)、白蛋白(ALB)、生长激素(GH)和胰岛素样生长因子-1(IGF-1)浓度在各组间均无显著差异(P>0.05)。④羔羊血浆谷胱甘肽过氧化物酶(GSH-Px)和超氧化物歧化酶(SOD)活性、丙二醛(MDA)含量及总抗氧化能力(T-AOC)在各组间均无显著差异(P>0.05)。【结论】孜然秸秆替代部分小麦秸秆能够提高羔羊采食量,对生长发育、屠宰性能、血浆生化指标及免疫和抗氧化功能均无负作用,可推广应用。

Abstract: 【Objective】 The experiment was designed to study the effects of different ratios of cumin straw replacing wheat straw on growth performance, slaughter performance and plasma biochemical parameters in lambs, in order to improve the utilization of cumin straw in Xinjiang, Gansu and other regions.【Method】 Using a one-factor design, twenty-seven healthy male lambs with similar body weight were selected and randomly divided into three groups:0 (control group), 30% (CS1 group) and 60% (CS2 group) of wheat straw were replaced with cumin straw respectively, and the rest components of the ration were the same.Nine lambs per group were fed individually, with 15 d of pre-test period and 60 d formal test period.During the experiment, the growth performance was measured. And after the trial period, the lambs were slaughtered after blood collection to determine the slaughter performance and plasma biochemical parameters.【Result】 ①The average daily feed intake (ADFI) of lambs in CS1 and CS2 groups were significantly higher than that of control group (P<0.05).There were no significant differences in the initial weight, final weight, average daily gain (ADG) and feed-to-weight ratio (F/G) among three groups of test lambs (P>0.05).②Slaughtering rate, live weight before slaughtering, carcass weight and eye muscle area were not significantly different among three groups (P>0.05).Heart weight of lambs in CS1 group was significantly higher than that in control group (P<0.05).There were no significant differences in weights and indices of liver, spleen, lung and kidney among three groups (P>0.05).③ No significant differences existed in the concentrations of plasma glucose(GLU), triglyceride(TG), total cholesterol(TC), total protein(TP), globulin(GLB), albumin(ALB), growth hormone(GH) and insulin-like growth factor-1(IGF-1) among three groups of test lambs (P>0.05).④ There were no significant differences in the parameters of plasma glutathione peroxidase(GSH-Px), superoxide dismutase(SOD), malondialdehyde (MDA) and total antioxidant capacity (T-AOC) among three groups of test lambs (P>0.05).【Conclusion】 Cumin straw replacing some of wheat straw could increase ADFI of lambs, with no adverse effects on growth, slaughter performance, plasma biochemical parameters, immune and antioxidant function.Cumin straw could be popularized and used in sheep production.
