高寒牧区育肥牛饲料配方筛选试验及效益分析

[目的]高寒牧区肉牛育肥对饲料的要求与其他地区存在着明显的差异,环境因素、气候条件、饲草料现状都是制约肉牛育肥产业发展的瓶颈。因此选择适宜的饲料配方对高寒牧区肉牛育肥产业的发展显得极为重要。[方法]本饲料配方筛选试验通过组间对比选择,筛选出适宜高寒牧区肉牛育肥的试验配方。在实际应用中取得了较好的效果。[结果]表明:筛选出适合本地育肥牛的1号料和3号料,饲喂1号料的A组比饲喂2号料的B组和4号料的D组,头均日增重高84g和142g(P0.01)差异极显著,头均多获利81.80元和147.18元;饲喂3号饲料的C组比饲喂2号料的B组和4号料的D组,头均日增重高64g和122g(P0.01)差异极显著。[结论]头均多获69元和133.84元。

Feed Formula Screening Test and Benefit Analysis of Fattening Cattle in Alpine Pastoral Areas

[Objective]The feed requirement for the fattening of beef cattle in alpine pastoral areas was significantly different with other regions. The environment factors, weather conditions and current feed straw conditions were the bottleneck to restrict the development of beef cattle fattening industry. So it was very important to screen the appropriate feed formulas for beef cattle fattening industry in alpine pastoral areas. [Method]The screening tests on feed formula were carried by the contrast between groups, which got better effects in practical application. [Result] The result showed that the first and third feed formula was fit for the local fattening cattle. The average daily weight gain per cattle in group A fed the first for- mula was 84 g and 142 g higher than that in group B fed the second formula and group D with the fourth formula, and the average earning profit per cattle was 81.80 and 147. 18 RMB. The difference was extremely significant. The average daily weight gain per cattle in group C fed the third formula was 64 g and 122 g higher than that in group B fed the second formula and group D with the fourth formula. The differ ence was also extremely significant. [Conclusion]The average earning profit per cattle was 69 and 133.84 RMB.
