Abstract
To evaluate the effect of substituting corn with barley grain on growth performance and eco-nomic benefits of cattle,twenty Simmental cattle with similiar weight were randomly divided into four groups and were fed corn-based diet(no supplied barley),1/3 barley-based diet,2/3 barley-based diet and barley-based diet.The experiment lasted for 54 days,with 7 days for adaption and 47 days for experiment.The results showed that the concentration of vomitoxin and aflatoxin in the diet decreased with the increase of substituted barley.The practice of substituting corn with different rations of barley didn't influence the growth performance and dry matter intake of cattle,but the average daily gain was shown in the order of corn-based diet(1.62 kg/d)＞barley-based diet(1.52 kg/d)＞1/3 barley-based diet(1.34 kg/d)＞2/3 bar-ley-based diet(1.32 kg/d).Fecal separator showed barley-based diet had highest digestibility,followed by corn-based diet,2/3 barley-based diet and 1/3 barley-based diet.The economic benefits ranked corn-based diet(44.02),barley-based diet(40.87),2/3 barley-based diet(33.93)and 1/3 barley-based diet(33.86).In summary,whole barley replacement is more effective than partial replacement,and it is recommended to feed fattening cattle with barley-based diet.关键词
