Problems solved by technology

[0005] The applicant has learned through visiting hundreds of large-scale intensive pig farms across the country that at present most pig farms lack a deep understanding of the nutritional technology of breeding boars, and some pig farms use pregnant sow feed to feed breeding boars; Although the farm uses boar feed, the ratio of nutritional components is not scientific enough, especially the content of nutrients that are closely related to the quality of boar semen is not enough and the ratio is improper, so the improvement of boar semen quality is not large, and cannot Solve the problem of declining semen quality of boars

Abstract

The invention relates to nutrient premix improving semen quality of service boars. The nutrient premix comprises L-carnitine, organic chromium, N- carbamylglutamate, vitamin E and carotene, and defatted rice bran is used as a carrier. The nutrient premix is reasonable and innovative in formula and conforms to growth, development and physiological characteristics of boars; after application, semen quality of the boars can be remarkably improved, ejaculation of the boars is increased, sperm mobility is improved, sperm density is increased, and teratospermia rate is decreased. In addition, the nutrient premix is low in cost and complies with actual production of a pig farm.

Description

technical field [0001] The invention relates to the technical field of pig feed nutrition, in particular to a nutritional premix for improving the quality of boar semen. Background technique [0002] Boars play an important role in pig reproduction. One boar can breed thousands or even tens of thousands of offspring a year, which has a great impact on production levels. As the saying goes, "A good sow makes a good litter; a good boar makes a good slope." It can be seen that boars play an important role in the breeding process of pig herds. The routine ratio of breeding boars and sows raised in intensive pig farms is as follows: ① Natural mating, boar: sow = 20-30; ② Artificial insemination, boar: sow = 100-200. It can be seen that the mating task of breeding boars is very heavy. The purpose of raising boars is to make the boars have good semen quality and mating ability, so that the sows can obtain high conception rate and litter size, and complete the mating task.
