Several misunderstandings of breeding sows

Unreasonable nutrition

1. Low energy Some farmers do not know the nutritional requirements of the sows. They are still using the traditional pig-breeding method, adding water to the rice, adding green material to feed, or giving a single concentrate, causing the sows to be too thin and affecting sow reproduction. Force and production level. 2. High energy Some pig farmers raise sows as fat pigs and feed pigs to make sows fat and cause sows to lose their estrus. 3. Inadequate mineral elements and vitamins Some pig farmers neglected the mineral elements calcium, phosphorus, silicon, etc. and vitamins A, D, E, etc. in the compound feed, resulting in some sows producing dead, teratogenic, and weak, severe Postpartum paralysis occurs.

Improper management

Some pig farmers don't feed the pigs in the feed trough and they directly sprinkle the feed on the cement floor to allow the pigs to feed freely. The surface is simple and convenient, and there is enough space for food intake. In fact, this is unscientific. When the pig eats material, the hoofs will step on the feed and bring some dirt and microorganisms. After entering the gastrointestinal tract of the pig, the light will cause malabsorption of nutrients, and the severe ones will cause some gastrointestinal diseases or infectious diseases. . Sometimes when spring and autumn harvests are busy, the feeding of pigs is often not timely, which can lead to prolonged water cuts, which can cause disorders of the gastrointestinal tract function, and may cause pigs to be unquiet and heterophilous.

Overweight and overweight

1. The gilts are too thin or too late to reach the weight of the bred, over-fat estrus, or estrus is not obvious. It is easy to miss the appropriate time for breeding, causing a mismatch, delaying 1 to 2 periods of love, or being accompanied by over-fertilization of the ovary, surrounded by fat around the ovary, limiting the development of egg cells, resulting in less calving. Due to excessive fat, breast milk has a high fat content. If the colostrum is too thick, the piglets can't digest it. When the fetus is finished, it causes a diarrhea. 2. Sows are too thin or over-fat Sows with more lactation and more milk during the feeding process, after weaning, the mother is very thin, it takes a certain time to reach 7-8. Another phenomenon is that sows with few litters, because they don't eat much according to their diets, cause excess nutrients and gradually become full of body fat. After sowlets are weaned, they do not have heat, which affects the timely mating.

Not according to season, number of times

Winter is cold, summer is hot, the same temperature, the amount of heat dissipation in winter, to increase the amount of appropriate materials, increase the energy of feed. In the summer sports field, shade sheds should be provided, and pigs should be given food to eat. The pig houses should be well ventilated. In terms of parity, after gilts are bred, although they are sexually mature, their bodies are not yet mature. Their own growth and development and the fetus' growth and development require nutrition. It is not the same as a sow, and it has a dual task. Therefore, the level of gilts for pregnancy should be higher than that of the sows. The kind of irrespective of fetal times, the effect will not be too good. The sows should be carefully reared, single-column feeding, and the amount of daily feeding adjusted according to the situation. After sow mating, the growth and development of fetuses at the age of pregnancy gradually increased the amount of material, and maintained a suitable 7-80% of the pupa. Sows are fed exclusively to the sow’s full-priced feed to ensure adequate protein, energy, minerals, and vitamins. The sows are fed without the moldy corn and the head of the drum. In addition, feeding sows use a feeding trough to ensure that the feed is clean and hygienic and prevents pigs from entering the feed trough and causing feed waste. And regular feeding will cause the pig to form conditioned reflexes so that it will grow well.
