不同饲草青贮料对肉牛育肥效果及经济效益分析

Analysis on Fattening Effect and Economic Benefit of Different Forage Silage to Beef Cattle

为了探讨不同饲草青贮料对西门塔尔牛育肥效果,选择月龄、体重相近的西门塔尔牛,随机分为3组,按照18∶82的精粗比混合饲喂,A组粗料为全株青贮玉米,B组为高丹草,C组为甜高粱。结果表明,各处理末重、干物质采食量无显著差异,A组日增重显著高于B、C组,料重比显著低于B、C组。各处理间A组经济效益最高,日毛利为16.61元/天·头,A组养殖效益分别比B、C组高20.48%、27.80%。综上所述,青贮玉米处理组较高丹草和甜高粱育肥肉牛日增重最高,经济效益最好。

In order to investigate the Fattening effects of different forage silage on Simmental cattle,Simmental cattle with similar age and body weight were randomly divided into 3 groups and fed with 18:82 ratio of concentrate to forage.The roughage of group A was whole silage corn,group B was sorghum-sudangrass hybrid,and group C was sweet sorghum,The results showed that the final weight and dry matter intake of each treatment had no significant difference,the daily gain of group A was significantly higher than that of group B and C,and the feed to weight ratio of group A was significantly lower than that of group B and C.Among all treatments,group A had the highest economic benefit,with daily gross profit of 16.61 yuan/day for head.The breeding benefit of group A was 20.48%and 27.80%higher than that of group B and C,respectively.In conclusion,the daily gain and economic benefit of fattening beef cattle in silage corn treatment group were the highest.
