Matters needing attention before sow breeding

The quality of feeding and management of sows before breeding has a direct impact on estrus and ovulation, so it is necessary to strengthen breeding before breeding to achieve normal reproductive performance and timely breeding. Strive for multiple births and prolificacy. So what should we pay attention to before sow breeding? Let's get to know it.

1. Pay attention to the fat condition of sows after weaning.

If the lactation task of normal sows is too heavy, resulting in serious loss of fat, there will be obvious malnutrition, and loss of fat in sows will lead to non-estrus or delayed estrus. Even if they are in estrus, there will be very little ovulation due to lack of nutrition, and the phenomenon of empty pregnancy is more serious, but if the fat is too fat, it will also lead to less estrus and ovulation in sows, which will seriously affect production performance and breeding benefits. it is generally appropriate to maintain 7-80% of the fat.

2. Pay attention to the health of sows

Attention should be paid to the health of the sow before breeding. If the sow suffers from hysteritis and other diseases, it will also affect its estrus, or have a small number of babies, or even have a miscarriage and weak stillbirth, which will bring huge economic losses to pig farming. Therefore, the immunization work should be completed in order before breeding, and we should also pay attention to pig sperm, which is also more important. if there is a problem with sperm quality, it will not only affect the production performance of sows, but also bring progress and epidemic situation into the herd of pigs. the consequences will be unimaginable.

3. Vulva disinfection

In breeding, must use disinfection drugs to do a good job of disinfection of the vulva of sows, after disinfection and then clean with clean water before breeding. Otherwise, bacteria, viruses and other harmful substances will be brought into the womb of sows, and the damage can not be ignored.

4. don't stress pigs before and after mating.

Do not beat and scold the sow before and after breeding, lest the sow will be frightened and have a stress reaction, which will also have a serious impact on pregnancy, and mating should not be in the case of noisy, round-turning, injection and medication, which will lead to a significant decrease in the number of pigs and return to green if it is serious.
