摘要
乳头性状是评估猪繁育能力的重要指标之一。通过乳头性状评估猪繁育能力在提高猪场生产水平、促进猪场经济效益中发挥重要作用。为了探索影响猪乳头性状的主要因素,提高猪繁殖性能,文章从猪的乳头数量、形态与分布、乳腺与乳头的发育、乳头性状的遗传力等方面对猪乳头性状进行了概述;并从猪的品种、杂交与近交、激素、猪乳头性状相关基因等角度归纳了影响猪乳头性状的因素,以期为改良母猪乳头性状、提高母猪繁殖性能、培育拥有优良经济特性的母猪品种(系)提供参考思路。
The trait of nipple is one of the important factors to evaluate the breeding ability of pig. Eralvation of pig reproductive capacity by nipple traits plays an important role in improving the production level and promoting the economic benefits of pig farms. In order to explore the main factors affecting the traits of pig nipple and improve the reproductive performance of pigs, the pig nipple traits were summarized from the number, shape and distribution of pig nipples, the development of breast and nipple, and the heritability of pig nipple traits in this article. And the factors affecting pig nipple traits were summarized from the perspectives of pig breeds, inbreeding and crosses, hormones, and genes related to pig nipple traits. The ideas for improving sow traits, improving their reproductive performance, and breeding sow breeds and strains with excellent economic characteristics were provided by studying these influencing factors.
