Unconventional feed capable of improving growth performance of beef cattle

The invention discloses an unconventional feed capable of improving the growth performance of beef cattle, which is characterized in that palm meal, soybean hull, guniting corn bran and manioc waste are mixed to replace part of corn concentrate, and the influence on the growth performance, nutrient digestibility, rumen fermentation and blood biochemical indexes of the beef cattle is researched; results show that the growth performance of the beef cattle is improved and health of the beef cattle is not affected after the four commercial crop byproducts including the palm meal, the soybean hulls, the guniting corn bran and the manioc waste are used for partially replacing the corn concentrate, and the effect is the best by combining 30% of corn, 12.5% of the guniting corn bran, 12.5% of the soybean hulls, 12.5% of the manioc waste and 12.5% of the palm meal. 本发明公开了一种能提高肉牛生长性能的非常规饲料，以棕榈粕、大豆皮、喷浆玉米皮、木薯渣混合替代部分玉米精料，研究对肉牛生长性能、养分消化率、瘤胃发酵及血液生化指标的影响，结果表明选用棕榈粕、大豆皮、喷浆玉米皮、木薯渣四种经济作物副产品部分替代玉米精料后提高了肉牛的生长性能且对肉牛健康无影响，其中，以30％玉米+
