How to use boars scientifically? Matters needing attention in boar breeding

The quality of boars is related to the development of the whole herd.

In order to give full play to the reproductive performance of breeding boars and improve the reproductive rate, we must pay attention to the rational utilization of boars.

This paper introduces how to make scientific use of boars and matters needing attention in boar breeding for reference.

1, the frequency of using boar depends on age. Under normal circumstances, 1~2-year-old young boars are still in the period of continuous growth and development, and it is appropriate to breed 3~4 times a week.

Adult boars aged 2-5 years have basically completed their physical development. Under the condition of good nutrition, you can use 1~2 times a day, 1 time in winter and 1 time in summer, but after continuous breeding, you should rest for 2 days a week.

Husband pigs over 6 years old can use/kloc-0 every/~ 2 days according to their physical condition and sexual desire.

2. According to the nutrition, the frequency of using boars should be reasonably used according to the nutritional status and feed conditions of boars in the breeding season.

In other words, boars with good nutritional status can be used several times, while boars with poor nutritional status should not only use less, but also feed more nutritious feed.

3, the number of times of use of artificial sperm collection boars Adult boars can collect sperm for 4 days a week. If they have good nutritional status and strong sexual desire, they can collect sperm 1~2 times a day, and boars can collect sperm 2~3 times a week.

If it is the first time for boars to collect sperm, or if they don't collect sperm for a long time, they should first check their sperm vitality, density and quality. For boars with unqualified semen quality, it is necessary to strengthen feeding management and use them only after the sperm quality is qualified by microscopic examination.

4. Matters needing attention in boar feeding should be carried out before feeding 1 hour or 2 hours after feeding. It is best to have a special site, and the ground should be flat and not slippery, which is convenient for breeding.

Boars mate for a long time, ranging from 3 to 25 minutes, so there must be no interference during mating; After each mating, let the boar move freely for more than ten minutes, then rush back to the pen and give it some warm water to drink.
