【摘要】：本文旨在应用Meta分析方法研究10~25 kg仔猪赖氨酸(Lys)需要量及其影响因素。本研究检索了1990年至2016年期间发表的有关仔猪Lys需要量的研究,根据文献筛选标准共17篇文献被纳入研究。用二次曲线(QC)模型、线性平台(LP)模型和曲线平台(CLP)模型估计了标准回肠可消化赖氨酸(SID Lys)需要量。结果表明:LP模型估计得到的SID Lys需要量较低,而QC和CLP模型的估计值较高且基本一致。其中,饲粮SID Lys含量变化不影响仔猪的平均日采食量(ADFI)(PQC=0.828 0,Plinear=0.584 4);以平均日增重(ADG)和料重比(F/G)为因变量,SID Lys含量为自变量,用QC模型估计得出10~25 kg仔猪饲粮SID Lys需要量分别为1.280%(P0.000 1)和1.260%(P0.000 1)。饲粮类型以及遗传背景等因素影响SID Lys需要量。其中,玉米-豆粕饲粮和非玉米-豆粕饲粮的SID Lys需要量分别为1.307%(P=0.005 0)和1.138%(P=0.000 1);中国地方猪种和瘦肉型猪种的SID Lys需要量分别为1.060%(P=0.001 2)和1.334%(P=0.004 3)。综上,为满足10~25 kg仔猪达到最佳生长性能,饲粮SID Lys需要量为1.230%~1.280%,同时应考虑饲粮类型以及猪的遗传背景等因素
[Abstract]:The purpose of this study was to study the Lys-Lys-lysine requirement of 10 ~ 25kg piglets and its influencing factors by using the Meta analysis method, and to retrieve the studies on the Lys requirements of piglets published from 1990 to 2016. According to the criteria of literature selection, 17 articles were included in the study. The standard ileum digestible lysine lysine (Sid Lys) requirement is estimated by the linear platform (LP) model and the curve platform (CP) model. The results show that the SID Lys requirement estimated by the SID / LP model is lower than that by the QC and CLP models. The change of dietary SID Lys content had no effect on the average daily feed intake (ADFI) of piglets. The average daily gain (ADG) and feed / weight ratio (F / G) were taken as dependent variables, and the content of Sid Lys was taken as independent variable, and the average daily gain (ADG) and feed / weight ratio (F / G) were taken as independent variables. By using QC model, the dietary SID Lys requirements of 10 ~ 25 kg piglets were estimated to be 1.280%(P0.000 _ 1) and 1.260%(P0.000 _ (1), respectively. Dietary type and genetic background were used to influence the SID Lys requirements. The SID Lys requirements of corn-soybean meal diet and non-corn-soybean meal diet were 1.307%(P=0.005 0 and 1.138%(P=0.000 1, respectively, and the SID Lys requirements of local Chinese and lean pig breeds were 1.060%(P=0.001 2 and 1.334%(P=0.004 3, respectively. The dietary SID Lys requirement was 1.230% and 1.280%, and the dietary type and genetic background of pigs should be taken into account.
