Sow breeding is the most important process in the sustainable development of the farm. However, if the sows do not fit in, even the white-breeding is the biggest waste on the farm. In order to solve this problem, I will now share with you some of the methods and experiences that I personally explored during the practice of raising pigs.
1. The insects were fed with levamisole to feed the sows, with 16 tablets per head. Once a day for 5 days.
2. Reduce half of the obese sows (this is the condition of the majority of farmers raising sows). All sows were fed more green feed.
3. Feed more feed to the lean sows to increase nutrition and improve sensation.
4. Bring the estrus's sows to the boar and let the boar crawl and tease them and promote their estrus.
5. Embolization with 10 mg per head of intramuscular injection of tweezers (Compound Epimedium injection).
6. Intramuscular injection with ovulation 3 injection during estrus increases litter size.
7. Sow the sow to sports grounds for more than 4 hours every day.
8. Add red clay or loess or cinder to the corner or playground of pigsty to increase the sow's absorption of iron and other trace elements.
9. Night light, light can stimulate ovarian activity.
10. After the estrus of the sow, use the method of compounding (ie, using the same boar for 8 to 12 hours apart) for more than two times.
So the above method is to let the sows heat up. Using these 10 measures, sows that are not estrus difficult to match, all can be equipped with a variety of breeds, producing a long and lively piglets. These methods have been applied in many farms.
