中小规模猪场母猪繁殖力低原因及提升措施

Causes and Improvement Measures of Low Fertility of Sows in Small and Medium-sized Pig Farms

繁殖力是母猪窝产仔数、产活仔数和泌乳能力的综合体现,也是猪场规模化壮大的基础。对于中小规模猪场,每头母猪年提供的断奶仔猪数数量越多,猪群分摊的养殖成本则越低,猪场的养殖效益才可增加,母猪繁殖力的提高是养猪效益提升的重要途径。该文首先从环境因素、管理因素、个体因素和营养因素4个方面分析中小规模猪场母猪繁殖力低的原因,然后提出环境控制、强化管理、择优选育、营养调控有针对性的策略来提升母猪繁殖力,为改善和提高母猪生产性能提供理论指导。

Fertility is a comprehensive reflection of litter size,live birth size and lactation capacity of sows,and it is also the basis for the scale and growth of pig farms.For small and medium-sized pig farms,the more the number of weaned piglets provided per sow year,the lower the breeding cost shared by the pig herd,and the breeding efficiency of the pig farm can be increased.An important way to improve the efficiency of pigs.This paper firstly analyzes the reasons for the low fertility of sows in small and medium-sized pig farms from four aspects:environmental factors,management factors,individual factors and nutritional factors,and then proposes targeted strategies for environmental control,intensive management,selective breeding,and nutritional regulation.Improve the fertility of sows and provide theoretical guidance for improving and improving the production performance of sows.
