In the pig farming industry, the reproductive capacity of sows is directly related to the economic benefits of the farm. If sow breeding is not in place, the sow will give birth to piglets, or the survival rate of the piglets will be very low. So how can we raise sows to be more productive? 1. Increase the number of piglets born by sows 1. Reproductive system conditioning Starting from gilts, by using conditioning agents containing Chinese herbs such as angelica , motherwort , and gynostemma pentaphyllum and probiotics, the development of the reproductive system is promoted, the ovulation volume and follicle quality are increased, and it is used during pregnancy to protect the fetus. 2. Nutritional supplements Sows consume a lot of energy when they are in estrus and ovulate, so they need adequate nutrition to ensure egg cell development and ovulation. Start supplementing nutrition half a month before mating, using nutritional supplements rich in multiple vitamins, trace elements, and amino acids to meet the nutritional needs of sows. 3. Hormone use Appropriate use of hormone drugs can promote ovulation, enhance corpus luteum function, and improve conception rate and embryo survival rate. However, hormone drugs should not be used frequently to avoid side effects. 2. Precautions for increasing litter size 1. Breeding time Choose to breed sows when they are in estrus, especially for reserve sows. It is not suitable to breed them when they are in estrus for the first time at 6 months of age. It is recommended to breed them when they are in estrus for the second time at 7 months of age or in estrus for the third time at 8 months of age. Gilts are bred on the third and fourth days of estrus, and sows are bred within 16-32 hours after estrus, at least twice. 2. Sow fatness Pay attention to the fatness of the sow. Being too thin or too fat will affect reproductive performance. The weight of sows should be controlled between 220 and 270 kilograms. If you are too thin, you can use nutritional supplements. If you are too fat, you need to control your food intake and increase your exercise. Through the above methods and precautions, the number of piglets born by sows can be effectively increased, thereby improving the economic benefits of the farm. I hope these suggestions will be helpful to my friends who raise pigs.
