摘  要：
为研究不同能量和可消化赖氨酸水平对PIC肥育猪生产性能的影响,试验1于2014年12月30日至2015年1月24日进行,选取127日龄PIC肥育猪40头,均重为78 kg左右,随机均分为A、B、C、D 4组,饲粮可消化赖氨酸水平均为0.70%,代谢能水平分别为12.51、12.64、12.76和12.89 MJ/kg,粗蛋白质、钙和有效磷水平分别为15.0%、0.61%和0.17%;试验2于2015年1月16日至2月10日进行,选取123日龄PIC肥育猪40头,均重为74 kg左右,随机均分为E、F、G、H 4组,饲粮可消化赖氨酸水平均为0.85%,代谢能水平分别为12.51、12.64、12.76和12.89 MJ/kg,粗蛋白质、钙和有效磷水平分别为16.0%、0.61%和0.17%。预试期均为3 d,试验期均为26 d。结果表明,在试验1中,A组猪的平均日增重比其余3组分别提高22.09%(P<0.05)、7.14%(P>0.05)和14.13%(P>0.05);在试验2中,H组猪的平均日增重比其余3组分别高出8.25%(P>0.05)、8.25%(P>0.05)和2.94%(P>0.05)。分别以可消化赖氨酸和代谢能水平作为单因子进行综合考虑,75~100 kg体重阶段PIC肥育猪最适宜的可消化赖氨酸和代谢能水平分别为0.85%和12.76 MJ/kg。

摘  要：
To study the effect of ME and digestible lysine levels on growth performance of PIC finishing pig.Experiment 1 was proceeded from Dec 30,2014 to Jan 24,2015,40 PIC finishing pigs(127 d) weighted 78 kg were selected andrandomly divided into four groups(group A,B,C and D),the ME levels of the four diets were12.51,12.64,12.76,12.89 MJ/kg respectively,and the digestible lysine(0.70%),CP(15.0%),Ca(0.61%) and P(0.17%)levels were the same.Experiment 2 was proceeded from Jan 16,2015 to Feb 10,2015,40 PIC finishing pigs(123 d)weighted 74 kg were selected andrandomly divided into four groups(group E,F,G and H),the ME levelsof the four diets were 12.51,12.64,12.76,12.89 MJ/kg respectively,and the digestible lysine(0.85%),CP(16.0%),Ca(0.61%)and P(0.17%) levels were the same.The preliminary and formal trial period were last for 3 d and 26 d both.The results showed that in trial 1,the ADG in group A was greater than that in the other groups by 22.09%(P<0.05),7.14%(P>0.05) and 14.13%(P>0.05) respectively.In trial 2,the ADG in group H was greater than that in the other groups by 8.25%(P >0.05),8.25%(P >0.05) and 2.94%(P >0.05) respectively.While the digestible lysine and ME level were considered as single factor,0.85% and 12.76 MJ/kg were the best for PIC finishing pig in 75 ~100 kg BW stage respectively.
