What problems should be paid attention to when feeding pigs with distiller's grains?

Distiller's grains are rich in phosphorus and B vitamins, but lack carotene, vitamin D and calcium, and also contain some alcohol. Therefore, distiller's grains are not suitable for feeding a large number of breeding pigs, especially pregnant sows and lactating sows, otherwise there will be abortion, stillbirth, deformity, weak fetus, piglet diarrhea and other phenomena. Distiller's grains are "fire" feed, which is easy to cause constipation. So the feeding amount should not exceed 65438+ 0/3 of the daily diet. When feeding, it is best to match some concentrate such as corn, bran and cake meal to supplement calcium and green feed.
