摘要
采用荟萃分析方法,通过整合2002—2022年共112篇文献的研究结果,拟合多项式函数、幂函数与Bridges函数3种函数模型来预测中国生长育肥猪的每日消化能摄入量与粗蛋白摄入量,并预测猪的体质量、饲粮消化能摄入量、饲粮粗蛋白摄入量与生长性能指标之间的函数关系。结果表明:3种函数模型均对消化能摄入量、粗蛋白摄入量进行了合理拟合,其中,多项式函数较幂函数与Bridges函数的拟合优度更高。多项式函数与Bridges函数对消化能摄入量的预测值整体上高于美国国家科学研究委员会(National Research Council, NRC)于2012年发布的《猪营养需要》[以下简称NRC(2012)]提供的数值;3种函数对粗蛋白摄入量的预测值整体上低于或接近于NRC(2012)提供的数值。本研究结果有助于制定更符合生长育肥猪营养需要的饲喂计划,为生猪饲料配制提供参考,从而提高饲料利用率、降低生猪饲养成本。
A meta-analysis method was used to integrate the results of 112 literatures from 2002 to 2022.Three functional models(polynomial function,power function and Bridges function)were fitted to estimate the daily digested energy intake(DEI)and crude protein intake(CPI)of Chinese growing-finishing pigs,and to predict the functional relationship between the body mass,dietary DEI and CPI,and growth performance indexes.The results showed that all the three functional models provided a reasonable fit for the DEI and CPI,and the polynomial function had a greater goodness of fit than did the power function and Bridges function.The predicted values of the DEI of the polynomial function and Bridges function were slightly higher than those of the Nutrient Requirements of Swine published by the National Research Council(NRC)in 2012[referred to as NRC(2012)],while the predicted values of the CPI of the three functions were slightly lower than or close to those of NRC(2012).The results of this study can be helpful to develop feeding plans which are more in line with the nutritional requirements of growing-finishing pigs,and to provide reference for the formulation of feed for pigs,so as to improve feed utilization efficiency and reduce the feeding cost of pigs.
