The nutritional requirements of pregnant ewes will change with different feeding methods at different stages.

Pregnant ewes have different nutritional needs at different stages, so they should be fed reasonably at different stages:

Sheep

1. The first month of pregnancy is the critical period for the growth and development of sheep embryos. After the ewes have reached satiety in grazing, they should also be properly fed concentrate according to the nutritional status of ewes.

Second, two months of pregnancy, gradually increase the feeding amount of concentrate of ewes, which is soaked in warm water for 6-8 hours, soaked in warm water for 6-8 hours, fed with 40% corn, 20% barley, 10% wheat, 10% soybean cake, 5% bran and 1% salt, and fed 2-3 times a day. Each ewe is fed 50 grams of 100 grams each time, and the feeding amount of young ewes should be increased appropriately.

Third, 3 months of pregnancy, properly control the total volume of forage grass fed to ewes, supplement forage and concentrate, should be fed less frequently, in case too much one-time feeding oppresses sheep embryos.

Fourth, four months of pregnancy, the amount of concentrate feed is twice that of the early pregnancy, and more feed such as tender forage and carrots are fed, and potato, distiller's grains and undetoxified cottonseed cake and rapeseed cake are prohibited. Feed with mildew spoilage, overcooling or overheating and excessive acidity is prohibited, so as not to cause abortion, dystocia and postpartum diseases in ewes.

5. One month before delivery, properly control the amount of coarse feed of ewes, try to feed the sheep with soft, green and juicy feed, and increase the amount of wheat bran in concentrate to facilitate bowels.

6. 10 days before delivery, reduce the amount of feed according to the digestion and appetite of ewes. 2-3 days before delivery, ewes' breasts are swollen, accompanied by subabdominal edema. Feed intake should be reduced by 1/2 to 1/3, so as to prevent excessive or thick milk in the early stage of delivery, causing mastitis, milk return and lamb dysentery. A week before delivery, the breast of the thin ewe is withered. In addition to reducing the amount of coarse feed, we should also appropriately increase protein-rich milk feed such as hemp cake, soybean cake, soybean milk and soybean dregs, as well as green and succulent laxative feed, so as to prevent ewes from postpartum milk deficiency.
