种猪生长性状校正公式研究
Research on the Correction Formula for Production Traits of Breeding Swines
摘要
Abstract
This study investigated and analyzed the current correction formulas for pig growth characteristics.Based on five common growth models,new correction formulas for pig weight in relation to age were proposed.Growth data for 2 439 boars were provided by enterprises.The growth curves of the pigs were fitted using a computer,and an analysis of the correction formula coefficients and goodness of fit was conducted.The effectiveness of the correction formulas was assessed,and the target age to reach 100 kg body weight for comparared with the current correction formulas.The experiments revealed that the five new correction formulas significantly outperformed the current correction formulas for correcting to 100 kilograms for pigs with weights in the range of 30 kilograms to 120 kilograms.The formulas proposed in this study exhibit versatility across different target ages,allowing enterprises to choose the most suitable correction formula based on factors such as breeding varieties and regional conditions.The research conducted in this paper can also be extended to the formulation of formulas for weight correction based on backfat thickness.关键词
