摘  要：
为研究不同日粮对德系西门塔尔杂交后代牛生长性能及经济效益的影响,选择18头体重相近的德系西门塔尔杂交牛,随机分成2组,每组3个重复,每个重复3头,分别饲喂2种日粮(带穗青贮玉米组与普通青贮玉米秸秆组)。青贮玉米秸秆指标测定结果显示:带穗青贮玉米组中秸秆粗纤维、酸性洗涤纤维含量显著低于普通青贮玉米秸秆组(P<0.05),而水分、粗蛋白质、中性洗涤纤维及酸性洗涤木质素含量两组间差异均不显著(P>0.05)。饲喂试验结果显示:带穗青贮玉米秸秆组肉牛的饲草消耗总量显著高于普通青贮玉米秸秆组(P<0.05),两组肉牛的初始重、末重、全期增重与平均日增重差异均不显著(P>0.05);试验期饲喂带穗青贮玉米组头均纯收益高于普通青贮玉米组,且头均日纯收益较普通青贮玉米秸秆组高近30%。综上,利用带穗青贮玉米饲喂肉牛增重效果与经济效益更佳。

摘  要：
The objectives of this trial were to study the effects of different dies on growth performance and economic benefit of German hybrid Simmental. Eighteen German hybrid Simmental were randomly assigned to 2 groups with 3 replicates per group of3 cataloes per replicate each group and were fed with different diets(whole corn silage group & corn straw silage group).The results showed that whole corn silage had apparently lower(P <0.05)contents of CF,ADF,compared with corn straw silage,but the contents of water, CP,NDF,ADL had no significant difference in two groups(P >0.05).Compared with corn straw silage group, the whole corn silage group had higher(P < 0.05)herbage intake, but there were no significant differences in the initial weight, final weight, total weight gain and ADG(P >0.05).In the experimental period, the whole corn silage group had higher average income each head(about 30%).In conclusion, feeding German hybrid Simmental with whole corn silage had higher weight gain and economic benefit.
