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.
