Early weaning technique not only may improve the sow production performance, but also improve the survival rates of piglets. Fodder protein is the main restricted factor of early weaned piglets’ production results. An appropriate protein level is the necessary condition to gua- rantee the health growth of piglets. Different protein level diets have an important influence on production performance of the early weaned piglets. By test results, when the protein level is in 14 percent to 20 percent range, the daily gain and average daily intake are gradually increased. Feed weight ratio and diarrhea rate are gradually reduced. Under the condition of the protein level in 20%, the daily gain and average daily intake achieve the maximum, feed weight ratio and diarrhea rate achieve the minimum. Protein level continues to rise and each index trends to the contrary. Keywords Protein, Early Weaned Piglet, Production Performance 日粮蛋白质水平对早期断奶仔猪生产性能的 影响 杨军峰 山东 新泰 文章引用: 杨军峰. 日粮蛋白质水平对早期断
