What about the poor quality of boar sperm?

As a kind of meat product with the largest annual consumption in our country, the breeding area of pork in our country is very large. When raising pigs, although the management of sows and young pigs is very important. However, we can not ignore the breeding of boars, often because of management problems lead to poor quality of boar sperm, affecting the pregnancy rate of mating. So what about the poor quality of boar sperm? The following editor will give you a brief introduction, let's have a look!

1. Feed

Improper feed feeding is one of the main reasons for the poor sperm quality of boars. When we raise boars, it is best to buy special materials for boars on the market for feeding. Because the nutrition of boar special material is very comprehensive, it is also very beneficial to the growth of boars. It should be fed at least twice a day, usually in the morning and evening. In summer, because of the high temperature and drought, it is necessary to feed by wet mixing. Increase the food intake of boars and balance the nutrition level of feed. After about 30 minutes of feeding, the trough should be cleaned in time to avoid fermentation deterioration of the residual feed.

2. Drinking water

Drinking water is also very important for the growth of boars. When feeding drinking water, we can't feed cold water at once. The amount of drinking water and water temperature should be controlled according to the changes of seasons. For example, in summer, because the temperature is very high, the boar's demand for drinking water will increase greatly, so the water outlet speed of the drinking fountain should be kept at least about two litres per minute. The water temperature should not be too high. If the water temperature exceeds 30 degrees, it will certainly have an impact on the amount of drinking water of boars. And it is very likely to cause a series of problems such as reduced food intake and constipation.

3. Physique

In addition to the eating and drinking water of boars, we should also pay attention to controlling the body condition of boars. Boar weight and sperm quality is also closely related, not too fat and too thin, body important to maintain about 180kg. For adult boars, in order to prevent overweight, feed restriction should be done well and feed should be fed according to the fatness of boars. Then in the cooler morning and evening, it is necessary to urge the boar to exercise more to ensure the boar's physical strength. Enhance the libido of boars, so as to improve the sperm quality and motility of boars.

4. Semen collection and breeding

After the body weight of boars has reached the breeding standard, semen collection and breeding will be carried out. When collecting semen, we still have to control the number of semen collection according to the age and body condition of the boar. For example, if it is an adult boar, the number of semen collection is about twice a week. If it is a boar on back, it will be about once, and it will be picked every week. Be sure to control the amount and frequency of semen collection, and never collect too much semen or over-breed to avoid harming boars.
