摘要
本试验旨在研究饲粮添加 Ｌ－精氨酸或 Ｎ－氨甲酰谷氨酸（Ｎｃａｒｂａｍｙｌｇｌｕｔａｍａｔｅ，ＮＣＧ）对经产母猪繁殖性能及血液参数的影响。选用 ３～４胎长白 ×约克杂交母猪 １２０头，随机分为 ３组，每组 ４０头母猪，每头母猪为 １个重复，从配种当天到分娩，分别饲喂含 １．７％ Ｌ－丙氨酸（对照组）、０．１％ ＮＣＧ和 １％ Ｌ－精氨酸盐酸盐的饲粮，测定妊娠母猪的繁殖性能和第 ０、３０、６０、９０天母猪静脉血血浆氨基酸、总一氧化氮合酶（ＴＮＯＳ）、诱导型一氧化氮合酶（ｉＮＯＳ）、一氧化氮（ＮＯ）、尿素和氨浓度。结果显示，与对照组相比，１％ Ｌ－精氨酸组窝产活仔数提高了１．１５头（Ｐ＜０．０５），仔猪初生窝重提高了 １．８８ｋｇ（Ｐ＜０．０５），０．１％ ＮＣＧ组窝产活仔数提高了０．５５头，仔猪初生窝重提高了 １．３９ｋｇ（Ｐ＜０．０５），初生个体重提高了 ７０ｇ（Ｐ＞０．０５）；１％ Ｌ－精氨酸组血浆精氨酸和鸟氨酸浓度显著提高（Ｐ＜０．０５），０．１％ ＮＣＧ组妊娠第 ９０天血浆亮氨酸、苯丙氨酸、瓜氨酸和脯氨酸浓度显著提高（Ｐ＜０．０５）；１％ Ｌ－精氨酸组和０．１％ ＮＣＧ组妊娠第 ３０、６０、９０天血浆 ＮＯ浓度和 ０．１％ ＮＣＧ组妊娠第 ９０天血浆 ＴＮＯＳ和 ｉＮＯＳ浓度显著提高（Ｐ＜０．０５），１％ Ｌ－精氨酸组妊娠第９０天血浆 ＴＮＯＳ浓度显著提高（Ｐ＜０．０５）；１％ Ｌ－精氨酸组和 ０．１％ ＮＣＧ组妊娠第 ６０天血浆尿素浓度显著降低（Ｐ＜０．０５）；０．１％ ＮＣＧ组妊娠第 ９０天和 １％ Ｌ－精氨酸组妊娠第 ６０、９０天血浆氨浓度均显著降低（Ｐ＜０．０５）。０．１％ ＮＣＧ组�
The study was conducted to investigate the effects of dietary L-arginine（L-Arg） or N-carbamylglutamate（NCG） on reproductive performance and blood parameters of multiparous sows.One hundred and twenty Yorkshire×Landrace multiparous sows（3 or 4 parities） were selected and randomly assigned into three dietary treatments including the control diet with 1.7% alanine（n=40）,0.1% NCG diet（n=40） and 1% L-Arg diet（n=40）.Parameters of reproductive performance were recorded immediately after farrowing.The concentrations of plasma amino acids,total nitric oxide synthase（TNOS）,inducible nitric oxide synthase（iNOS）,nitrogen monoxide（NO）,urea and ammonia of the sows were determined on d 0,30,60 and 90 of gestation.The results were showed as follows： compared with the control group,1% L-Arg supplementation increased the number of piglets born alive by 1.15（P0.05） and litter birth weight of all piglets born alive by 1.88 kg（P0.05）;0.1% NCG supplementation increased the litter birth weight of all piglets born alive by 1.39 kg（P0.05）.The concentrations of plasma arginine and ornithine of the sows treated with 1% L-Arg and the concentrations of plasma leucine,phenylalanine,citrulline and proline of the sows treated with 0.1% NCG were significantly higher than those of the control group at d 90 of gestation（P0.05）.The sows in 1% L-Arg group and 0.1% NCG group had higher NO concentrations than that of the control group on d 30,60 and 90 of gestation（P0.05）;the concentrations of plasma TNOS and iNOS of the sows in 0.1% NCG group were higher than those of the control group on d 90 of gestation（P0.05）,and plasma TNOS concentration of the sows in 1% L-Arg group was higher than that of the control group on d 90 of gestation（P0.05）.Both the sows in 1% L-Arg group and 0.1% NCG group had lower plasma urea concentrations than that of the control group on d 60 of gestation（P0.05）.Plasma ammonia concentration of the sows in 1% L-Arg group was lower than that of the control gro
