How do sows give birth to many babies

Raising pigs is what many farmers are doing. the number of births is directly related to everyone's income. Generally speaking, they want to have as many babies as possible. But the general farmers do not know how to improve the litter yield, the following pro-agricultural network to teach you some methods conducive to improving the litter yield of sows, to solve some of our problems.

1. Selection of high quality varieties

This is one of the cores of the whole process, and the normal breeding yield of pigs with high litter size will be relatively high. It is recommended to choose relatively docile sows, the number of nipples is better, the latter part of the pig is relatively large, this kind of pig is easy to be prolific. It is suggested that according to the actual local breeds, the sows with the largest litter size in China should be Taihu sows. The initial production can reach more than 12 heads, and the number of offspring produced in the later stage can be doubled.

2. Feeding and management

The feeding of high-quality sows is very important to the yield, when to feed what, how much to feed all need to pay attention. In the early stage of breeding, you need to feed more things that help to increase production, preferably with raw materials, such as potatoes, sweet potatoes and so on, which help sows ovulate in the later stage. Half a month before each mating, we should properly feed some high-quality concentrate feed containing a variety of trace elements. During pregnancy, in order to ensure the survival rate of the cub, it is necessary to feed some high-energy protein feed to ensure the nutritional supply.

3. Selection of mating time

Sow breeding time is also fastidious, the early sow suitable breeding age needs to be about 8 months old, too small is not conducive to production. The number of ovulation in sows increases according to the number of estrus, and each oestrus is generally 1-2 more than the previous one. It is recommended to breed at least during the second estrus, which will last about three times. The ovulation of sows is concentrated within 1-2 days after estrus, and the maximum ovulation is about a day and a half later, which is the best time for both quantity and vitality.

4. Postpartum nursing

Postpartum care is also a very important thing, nursing good late output can continue to increase. The nutrition after production should first keep up, and the intake of all necessary elements must be adequate for half a month, so that the production site of sows can be better restored or even further developed. At this time, the feed is finer and more hydrated, which helps sows to absorb quickly. Finally, disinfection must be paid attention to, whether it is a sow or a pigsty.

Pig breeders all want to increase the number of sows to give birth, which is normal, but the later fertility should not be destroyed for the sake of a single birth, and the yield should be increased step by step through management means. some of the yield survival rate caused by drugs is a big problem. I hope you can still improve the science.
