Several kinds of feed that should not be fed and should not be fed more to sows
1. Although distiller's grains is rich in crude protein and crude fat (especially the crude protein content in dry distillers' grains reaches 2% to 25%), it lacks carotene, vitamin D and calcium, and contains a certain concentration of alcohol. Therefore, it is not suitable to feed a large number of pregnant sows and lactating sows, otherwise it is easy to lead to miscarriage, stillbirth and weak litter. Even if you give birth to piglets, it is easy to have diarrhea.
2. Powder residue is a by-product of making powder or noodles from raw materials such as peas, red beans or potatoes, which contains little crude protein and starch, and the quality is poor. Feeding in large quantities with powder residue often causes weight loss and less milk in sows, and it is also easy to cause sows to have diarrhea. Long-term feeding will make sows give birth to stillbirths and deformed piglets, resulting in stunted piglets and prone to skin diseases. Therefore, powder residue should not be used to feed sows, such as a small amount of feed, it must also be matched with protein feed, green feed and calcium.
3. Sugar residue is a by-product of sugar industry, which has sweet taste and contains sugar, starch and protein. Can be used to feed growing pigs. However, pregnant sows can not be fed with sugar dregs, because the sugar dregs contain 55% potassium salt, which has a strong irritation to the gastrointestinal mucosa of pigs, has a strong diarrhea, and is easy to cause diarrhea.
4. Corn and sorghum are mainly fed to sows for a long time, which will reduce the conception rate of sows, give birth to stillbirths, weak piglets, and even hairless piglets. Therefore, the diet based on corn and sorghum should be mixed with all kinds of green feed, wild high-quality hay meal, fish meal and other feeds with more riboflavin. There is a lack of green feed in winter and spring, so corn, bean cake and other feed can be fermented and fed to sows. In addition, it should be recooked and fed as dry feed, and the diet should be mixed with alfalfa powder, peanut cake, bran and other feeds with more pantothenic acid.
5, carbohydrates such as excessive supply of carbohydrates, sows deposit a lot of body fat, so that sows are too fat, low libido, not easy to estrus, repeated infertility, prone to dystocia, stillbirth and less litter, and so on. The results showed that when the metabolic energy of sows increased from 25.1 MJ to 29.3 MJ per day, the litter size of sows would be reduced by 1.9. Therefore, it is not suitable to feed sows with high carbohydrate diets.
