How to improve the reproductive ability of sows

In the process of pig breeding, farmers attach great importance to sows, and the reproductive capacity of sows determines the production efficiency and profits of the farm. If the production capacity of pigs is not good, it will result in profits and losses of the farm. So the reproductive capacity of sows is particularly important. Of course, the production capacity of sows can also be directly affected by genetic factors, so how can we improve the reproductive capacity of sows? Next Shuai Shuai will tell you about it!

First, to ensure the semen quality of boars

If you want to breed successfully, you must first improve the semen quality of boars, extract the semen of boars, and choose high-quality fresh semen for breeding. Semen must not be taken for too long, that is, it can be used immediately. Large-scale commercial farms can mix semen of the same breed, which can greatly improve the reproductive capacity of sows.

Second, do a good job in the feeding and management of reserve sows

The management of the reserve sow must be in place, especially the feed, if the sow is fed more than a week before conception, it will be of great help to the estrus of the sow during mating, and it can also promote ovulation. The weight of the first conception of the reserve sow determines whether it can continuously produce high yield and prolong the life span. The delayed mating time of reserve sows can increase the litter size and the pregnancy rate, so the effect of feed on it is very helpful. Adding a large amount of sows a week in advance can make it easier to mate.

III. Nutritional regulation of sows

Sows should not only pay attention to the management of feed, but also pay attention to the matching of nutrition before reproduction. the nutritional demand of sows during lactation is very high, and they can continue to increase before weaning. Regulating nutritional balance after weaning can help them to better estrus and ovulate more, and then control their feed quantity four weeks after successful pregnancy. The nutrition of sows in the late stage of pregnancy and during lactation should mainly be feed rich in high-energy protein.

IV. Reasonably eliminate sows with low reproductive capacity

Because the reproductive capacity of sows directly affects the benefit and profit of the farm, we should reduce the breeding cost as much as possible, and we can evaluate the production performance of sows before reproduction. if its production performance is very low, it can be eliminated directly, which can ensure that the pregnancy rate and the number of sperm are not wasted, and save some special feed costs and other extra costs for sows. A lot of cultivation costs are saved.

Strengthening the health care and management of sows

Sows must ensure that there are no diseases before breeding, and ensure the health of sows, so that they can avoid fetal death due to their own diseases in the later stage, and the big and small ones may not be protected. This is a very great loss to the pig farm, and some diseases are still contagious, so we must do a good job in pre-breeding inspection, sanitary management and ventilation of the pig house. Only in this way can we avoid the growth of germs and bacteria and reduce a variety of possible factors and conditions.

VI. Prevention and treatment of uterine inflammation

For the reproduction of sows, hysteritis is also a very influential disease that causes infertility, which basically occurs most frequently in summer, so it still has something to do with the health care of sows. In addition, if you have hysteritis after delivery, you must first treat it, and then wait for it to recover before you can continue the next breeding. You must pay attention to hygiene during each pregnancy. Otherwise, it is very easy to infect sows with uterine inflammation.

The above is how to improve the reproductive capacity of sows, see here we all know what to do and where the problems are, in fact, most of them are not done well in the health care of sows, leading to a series of problems.
