母猪终身繁殖性能现状、影响因素及改善措施OA
Current Status,Influencing Factors and Improvement Measures of Lifetime Reproductive Performance of Sows
随着畜牧业集约化发展程度的不断提升,母猪生产的单一指标如每头母猪每年提供的断奶仔猪数或母猪的生产寿命已经不能满足全面反映猪群繁殖性能的需求,因此提出母猪终身繁殖性能(LRP)的概念,以全面概括并充分利用母猪的繁殖潜力,并通过最大限度地提高所有母猪的 LRP,从而降低养殖场的生产成本.本文将从母猪 LRP 现状、影响因素及改善措施 3 个方面进行综述,旨在为提高母猪繁殖效率及促进畜牧业可持续发展提供参考.
With the continuous improvement of the degree of intensification in animal husbandry,single indica-tors of sow production,such as the number of weaned piglets provided by each sow per year or the production life of sows,can no longer meet the demand for comprehensively reflecting the reproductive performance of pig herds.Therefore,the concept of sow lifetime reproductive performance(LRP)is proposed to comprehen-sively summarize and fully utilize the reproductive potential of sows,thereby reducing the production costs of pig farms by maximizing the LRP of all sows.This article conducts a review from three aspects:the current status of LRP in sows,influencing factors and improvement measures,aiming to provide references for enhan-cing the reproductive efficiency of sows and promoting the sustainable development of animal husbandry.[Chi-nese Journal of Animal Nutrition,2026,38(5):3209-3229]
