摘　　要：为研究不同比例棉籽粕、玉米酒精糟(DDGS)和味精渣替代豆粕对鲁西牛生长性能、血清指标及经济效益的影响,选择体况良好、体重(250±20)kg的鲁西牛36头,随机分为3组,每组12头。对照组饲喂基础饲粮,5%和10%豆粕替代组分别采用棉籽粕、DDGS和味精渣混合替代精料补充料中5%豆粕和10%豆粕。预试期15 d,正试期60 d。结果表明:不同处理组肉牛的干物质采食量(DMI)和日增重(ADG)无显著差异(P>0.05),但5%豆粕替代组的料重比显著低于对照组(P<0.05);对照组的干物质表观消化率(DMD)最高(82.28%),10%豆粕替代组的蛋白质表观消化率(CPD)最高(64.68%);5%和10%豆粕替代组的谷丙转氨酶(ALT)和谷草转氨酶(AST)含量较对照组显著降低(P<0.05);不同处理组肉牛血清的免疫、抗氧化和激素指标无显著差异(P>0.05);5%豆粕替代组的每头牛每天毛利润比对照组和10%豆粕替代组分别高0.54元/d和0.68元/d。综上可知,采用棉籽粕、DDGS、味精渣替代精料补充料中5%的豆粕可降低肉牛料重比,增加经济效益。To study the effects of different proportions of cottonseed meal,corn alcohol residue and monosodium glutamate residue replacing soybean meal on growth performance,serum indexes and economic benefits of Luxi cattle.Thirty-six Luxi cattle with good body condition and similar body weight of(250±20) kg were randomly divided into 3 groups with 12 cows per group.Cattle in the control group were fed a basal diet,and those in 5% and 10% soybean meal replacement group were fed a mixture of cottonseed meal,DDGS and MSG residue to replace 5% and 10% soybean meal in concentrate supplement,respectively.The pre-trial period lasted for 15 days and the experimental period lasted for 60 days.The results showed that dry matter intake(DMI) and daily gain(ADG) of beef cattle in different treatment groups had no significant difference(P> 0.05),but the feed to gain ratio of 5% soybean meal replacement group was significantly lower than that of control group(P < 0.05);The apparent digestibility of dry matter(DMD) in the control group was the highest(82.28%),and the apparent digestibility of protein(CPD) in the 10% soybean meal replacement group was the highest(64.68%).The contents of alanine aminotransferase(ALT) and aspartate aminotransferase(AST) in5% and 10% soybean meal replacement groups were significantly lower than those in control group(P <0.05);There were no significant differences in immune,antioxidant and hormone indexes in beef serum among different treatment groups(P > 0.05);The gross profit per head per day in 5% soybean meal replacement group was 0.54,0.68 yuan/d higher than that in control group and 10% soybean meal replacement group,respectively.In conclusion,replacing 5% soybean meal in concentrate supplement with cottonseed meal,DDGS and MSG residue could reduce feed to gain ratio,increase economic benefit.
