Causes of dead sperm in Duroc boars

1. Not often used

Usually Duroc boars that have been idle for a relatively long time will show a large number of aged and dead sperm in their semen, so when you choose this Duroc boar as a breeding boar, do not leave it idle for a long time. When it serves as a breeding boar, sperm testing needs to be carried out two weeks in advance.

2. Malnutrition

If a Duroc boar is in a state of nutritional deficiency, at this time a large number of sperm in its semen will die, and using any medication has no effect.

Generally, the feed used for feeding needs to be rich in vitamin E and vitamin A, and also contains mineral components; only this can ensure the nutrition of the Duroc boar.

3. Mixing in harmful substances

During the process of ejaculation and semen collection, it must be noted that urine or other harmful substances must not be mixed in. Therefore, these two steps must be carried out with special care, and operation in a sterile environment is generally required, so that no foreign matter will be mixed in.

4. Unhealthy

Usually Duroc boars will have some diseases, such as inflammation of the reproductive organs. At this time, the acidic substances in the semen of the Duroc boar will increase, which will reduce the sperm survival rate, and there will also be a certain degree of contagiousness. At this time, isolation should be carried out for disinfection and treatment.

5. Caused by weather

If high temperature and high humidity continue, it is very easy to cause the scrotal temperature regulation of the Duroc boar to go out of control, and it will also trigger febrile diseases, causing high fever, which may also cause sperm death.
