摘　　要：文章旨在探究日粮添加番茄渣对肉牛生长性能,免疫指标和肉品质的影响。试验选择均重(583.69±17.36)kg的健康安格斯肉用公牛144头,随机分为4组,每组6个重复,每个重复6头。对照组饲喂基础日粮,试验组在基础日粮中添加2%、4%和8%的番茄渣。结果显示,8%的番茄渣组肉牛的末重显著提高2.94%(P<0.05),平均日增重显著提高8.94%(P<0.05),8%的番茄渣组肉牛平均日采食量显著提高5.13%(P<0.05);料肉比显著降低3.47%(P<0.05)。8%的番茄渣组肉牛胴体重显著提高(P<0.05);4%和8%的番茄渣组肉牛背最长肌剪切力显著降低(P<0.05),背最长肌总多不饱和脂肪酸(T-PUFA)含量显著提高(P<0.05),4%的番茄渣组肉牛背最长肌总氨基酸(TAA)含量显著提高(P<0.05)。添加4%和8%番茄渣组肉牛血清免疫球蛋白A(IgA)和白细胞介素-6(IL-6)含量显著提高(P<0.05);添加4%番茄渣组肉牛血清白细胞介素-1β(IL-1β)和干扰素-γ(IFN-γ)含量显著提高(P<0.05);添加2%~8%的番茄渣组肉牛血清溶菌酶(LZM)含量显著提高(P<0.05)。结论:添加8%的番茄渣能促进肉牛生长,改善肉质并提高其免疫力。The purpose of this experiment is to investigate the effects of adding tomato residue to the diet on the growth performance,immune indicators,and meat quality of beef cattle.144 healthy Angus beef bulls with an average weight of(583.69±17.36)kg were randomly divided into 4 groups,with 6 replicates in each group.The control group was fed with a basic diet,while the experimental group added 2%,4%,and 8%tomato residue to the basic diet.The results showed that the final weight of beef cattle in the 8%tomato residue group significantly increased by 2.94%(P<0.05),and the average daily weight gain significantly increased by 8.94%(P<0.05).The average daily feed intake of beef cattle in the 8%tomato residue group significantly increased by 5.13%(P<0.05);The feed to meat ratio significantly decreased by 3.47%(P<0.05).The 8%tomato residue group significantly increased the carcass weight of beef cattle(P<0.05);The shear strength of the longest back muscle of beef cattle in the 4%and 8%tomato residue groups was significantly reduced(P<0.05),and the T-PUFA content in the longest back muscle was significantly increased(P<0.05).The TAA content in the longest back muscle of beef cattle in the 4%tomato residue group was significantly increased(P<0.05).The serum IgA and IL-6 levels of beef cattle were significantly increased in the group of adding 4%and 8%tomato residue(P<0.05);Adding 4%tomato residue to beef cattle serum IL-1βAnd IFN-γThe content significantly increased(P<0.05);The addition of 2%~8%tomato residue significantly increased the serum LZM content of beef cattle(P<0.05).Conclusion:Adding 8%tomato pomace can promote beef cattle growth,improve meat quality,and enhance their immunity.
