摘要
该试验选择健康状况良好、体重接近的仔猪240头,研究净能—可消化氨基酸平衡日粮对断奶仔猪的生产性能和氮排放的影响。结果表明,蛋白水平18%和20%,氨基酸水平相同的日粮对仔猪的日均耗料量和日均增重均没有影响(P>0.05);与对照组相比,净能—可消化氨基酸平衡日粮可显著提高蛋白消化率,同时显著降低粪便中氮的含量(P<0.01)。
This experiment selected 240 heads of weaned piglets which were in good health and had similar body weight,and studied the effects of low-protein and amino acid balanced ration on growth performance and nitrogen excretion of weanling pigs.The results showed that Dietary protein content had no effect on daily gain and feed conversion ratio(P>0.05),in both standard(20%)and low-protein(18%)diets.Compared with control group,Low protein amino acid balanced diet can improve the digestibility of crude protein(P<0.01)while reducing the nitrogen content in feces(P<0.01).
