摘要:

仔猪早期断奶已成为规模化养殖生产中采取的一项重要手段。早期断奶技术可提高母猪生产性能,也有利于提高仔猪的成活率。饲粮蛋白质是制约早期断奶仔猪生产成绩的主要因素。仔猪适宜的蛋白质水平是保证仔猪健康生长的必要条件。日粮蛋白水平对早期断奶仔猪生产性能有重要影响。由试验结果可知,日粮蛋白质水平在14%~20%的范围内,平均日增重、平均日采食量都逐渐增加,料重比与腹泻率都逐渐降低。在蛋白质为20%条件下,平均日增重与平均日采食量达到最大,料重比与腹泻率都达到最小。蛋白质水平继续升高各指标趋势相反。

Early weaning of piglets has already become an important means of intensive and mass breeding production. 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 guarantee 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.
