摘  要：
将90头平均体重为(32.0±1.5)kg的杜长大三元杂交猪随机分为5个组,每组3个重复,每重复6头猪;1组为对照组(粗蛋白质水平17.47%、可消化赖氨酸水平0.80%),2～5组为试验组,采用2×2因子设计,粗蛋白质水平为15.46%和13.49%与可消化赖氨酸水平为0.80%和0.85%。试验期50d。结果:(1)日粮粗蛋白质水平15.46%、可消化赖氨酸水平0.80%,对猪的生长性能无影响(P>0.05),尿氮排出量显著降低;当可消化赖氨酸水平增至0.85%时,猪的日增重显著提高(P<0.05),尿氮、粪氮排出量显著降低。(2)日粮粗蛋白质水平13.49%、可消化赖氨酸水平0.80%,对猪的生产性能无影响,尿氮、粪氮及总氮排出量显著降低;当可消化赖氨酸水平增至0.85%时,影响猪的生长。结论:日粮粗蛋白质水平降低4个百分点,可消化赖氨酸水平保持0.80%不变,对生长猪生长性能无影响,氮排泄量显著降低。

摘  要：
90 DLY cross bred pigs(32.0±1.5 kg) were randomly allocated into 5 groups,3 replicates per group,6 pigs in each replicate to investigate the effects of dietary protein and lysine on growth performance and nitrogen excretion in growing pigs.2×2 factors were designed.Control group was fed with diet of 17.47% crude protein(CP) and 0.80% digestible Lys(Dly).4 treatment groups was fed with diet of 15.46%,13.49% CP and 0.80%,0.85% Dly,respectively.The test duration was lasted for 50 days.The results showed that the treatment fed with diet of 15.46% CP and 0.80% Dly has not effect on the growth performance in growing pigs in comparison with others(P>0.05),but compared to the control,urinary nitrogen was significant decreased(P<0.05).The treatment fed with diet of 0.85% Dly,ADG are increased significantly(P<0.05) and feces nitrogen and,urinary nitrogen are decreased significantly(P<0.05) in comparison with others.The treatment fed with diet of 13.49% CP and 0.80% Dly has not effect on the growth performance in growing pigs(P>0.05) compared to the others,urinary and feces nitrogen and total nitrogen was significant decreased(P<0.05) compared to the control.The treatment fed with diet of 13.49% CP and 0.85% Dly has effect on the growth performance in growing pigs.The results indicate that diet of 13.49% CP and 0.80% Dly has not effect on the growth performance in growing pigs(P>0.05) but at the same time nitrogen excretion is significant decreased in comparison with the diet of 17.47% CP and 0.80% Dly(P<0.05).
