Description

Premixed Feed for Improving Boar Reproductive Performance

technical field

The invention relates to a feed, in particular to a premixed feed for improving the reproductive performance of boars.

Background technique

With the continuous improvement of the scale of pig breeding, the number of boars in pig farms has an increasing demand. For the group, the impact of boars is far greater than that of sows, because it has more offspring than sows. Under normal inbreeding conditions, one adult boar can be paired with 30-40 sows in one year. If artificial insemination is used, one boar can mate with hundreds of sows and breed thousands of piglets a year. If the quality of boar semen is not good, it will not only cause infertility in sows, but also directly affect the quality of offspring. The offspring piglets are weak and their vitality is reduced, resulting in a gradual decline in the quality of the herd. How to ensure the rational use of breeding boars and ensure the quality and quantity of boar semen is an important guarantee for improving the economic benefits of intensive pig farms, and has a very important impact on the performance of the entire pig production.

In the current large-scale breeding, the activity place of boars is greatly restricted and the task of mating is quite heavy. Therefore, to improve the fecundity of boars largely depends on the quality of the diets fed: balanced nutrients, reasonable Raw material matching, high-quality raw materials. However, with the continuous expansion of large-scale pig farms and the maturity of artificial insemination technology, the quality of boar semen has a greater impact on the pig industry, and it is imminent to develop a premix that improves the performance of boars.
