Vitamin composition specially used for boars, and preparation method of vitamin composition

Abstract

The invention relates to a vitamin composition specially used for boars, and a preparation method of the vitamin composition. The vitamin composition comprises the following components in parts by weight: 10-15 parts of vitamin A, 10-15 parts of vitamin E, 10-20 parts of vitamin C, 10-20 parts of biotin, 10-20 parts of beta-carotene, 5-10 parts of folic acid and 1-5 parts of choline. The vitamin composition is capable of maintaining the normal dark adaptation ability, maintaining the normal vision, promoting the biosynthesis of protein and the differentiation of bone cells, promoting the growth of organisms and the development of bones, promoting the development of egg cells, improving the quality of the egg cells and increasing the number of ovulation, being beneficial to mating, reducing the number of mating omission and the non-pregnant number, improving the vigor and number of sperm cells, increasing the litter size, promoting the oestrus of pigs, shortening the weaning mating interval, reducing the elimination rate of breeding sows, reducing the elimination rate of the boars, improving the fertility and increasing the number of weaned piglets every year.

Description

technical field [0001] The invention belongs to the field of feed additives, in particular to a special vitamin composition for breeding pigs and a preparation method thereof. Background technique [0002] Efficient and profitable pig production depends on a high level of reproductive performance in sows. The factors that affect the reproductive performance of sows include genetics, nutrition, diseases, environment and feeding management. Among them, nutritional factors include energy, protein, mineral elements, vitamins and so on. Vitamins are low-molecular-weight organic compounds that are necessary for animal metabolism and require very little. There are currently 14 types of vitamins that have been identified, which can be divided into fat-soluble vitamins and water-soluble vitamins according to their solubility. Because of its very small proportion in animal feed, its role is often overlooked, especially in the reproductive performance of breeding stock. However, stu...

AI Technical Summary

Problems solved by technology

However, research at home and abroad has found that almost all vitamins have some degree of influence on the reproductive performance of breeding pigs

Lack of vitamins will affect the litter size of sows, prolong the estrus of sows and shorten the time of weaning and mating, affect the elimination rate of breeding pigs; also affect the survival rate of embryos, and indirectly affect the immunity of sows to piglets
