Effects of first parity production parameters of French sows on second parity reproductive performance in multi-story pig farms
摘要
Abstract
This study aimed to investigate the effects of key first parity production parameters and second parity mating season on the reproductive performance of French sows in their second parity under a multi-story pig building system,providing a scientific basis for optimizing 28-day batch production and gilt management strategies in such systems.Using reproductive records from 9 223 second parity French sows across four production lines in a large-scale multi-story pig farm in Guangdong,general linear model were em-ployed to analyze the fixed effects of production line,breed,mating season,and first parity production parameters on second parity re-productive traits.Variance analysis revealed that production line,breed,second parity mating season,and first parity weaning-to-mat-ing interval group had highly significant effects on second parity reproductive traits(P＜0.01),while first parity gestation length group and first parity litter size group had significant effects(P＜0.05).In 28-day batch production within multi-story pig buildings,optimizing gilt first mating age,precisely managing first parity gestation length,lactation period,litter size,and weaning-to-mating interval can ef-fectively enhance the second parity reproductive performance of French sows.关键词
