First, control the public opinion In order for the sow to have a breeding condition, it is necessary for the sows to have more productive abortions, and to produce a good one, so that the breeding condition for preparing thin and not fat must be too thin, the nutrition is insufficient, the fetus is not well developed, the piglets have poor post-natal vitality, and the quality is poor; Obesity, easy birth, or fewer litters. The sow breeding sensation maintained at 5?7 became the most appropriate, and the itch during the entire pregnancy remained at 6?8 as the best. Therefore, according to the sow's body condition, the amount of concentrate feed is increased or decreased so that it has a breeding condition. Second, strengthen feeding management to ensure the quality of breeding The amount of breeding is directly related to the number and strength of piglets. In order to ensure high yields of multiple sows, sows born after being weaned can receive 200 mg of VE in the sow diet. When the sows are close to the species, they are chopped with half a catty of leeks and fed into the feed each day. A few days before the sow’s estrus, 1000 units of chorionic gonadotropin can also be injected intramuscularly. For sows with poor estrus, aphrodisiac can be used: Angelica 20 grams, Rehmannia 30 grams, Cistanche, Epimedium each 35 grams, 15 grams of white peony root, Yang from stone 30 grams, Motherwort 40 grams, Jianshui seasoning The aphrodisiac effect is particularly good. When mating a sow, it should be done 24 to 48 hours after the sow has started estrus. Within one month after sow mating, more fish meal or bean cake can be fed, and VE80 mg can be added to the diet, which is extremely beneficial to the development of the embryo.
