Sheep can be grazing all year round. However, once the winter grassland is dry, the nutritional value is significantly reduced. Sheep bred and grazing, and wheatgrass ingested, are difficult to meet the nutritional needs both quantitatively and qualitatively. At the same time, as the weather is cold, the loss of thermal energy in the sheep body increases, resulting in insufficient nutrition for most sheep, slow growth of lambs, thin and weak constitution, low survival rate, poor development of young sheep, and low productivity of adult sheep. In order to change this situation, the most effective way to do a good job of protecting and preventing fetuses is to supplement the sheep in winter and spring. Supplementary feed forage Before the arrival of winter, a certain amount of forage and feed should be stocked. Generally, it is required that each sheep store 300-500 kg of hay and 100-150 kg of concentrate. Feeding time starts from November until the beginning of the second year of May. Feeding of sheep in winter and spring includes soybeans, bean cakes, corn, barley, wheat bran and rice bran. The fine material must be crushed and the bean cake should be soaked and fed. The addition of 30% to 40% of high-quality hay powder in concentrates can increase the utilization of hay, aid digestion and absorption, and also save feed. Silage corn stalks, carrots, foraging sweeteners, etc. are good feed for sheep in winter and spring. In winter and spring, the sheep are supplemented with such good succulent feeds, which can fully supply sheep's sugar and various vitamins, and increase the milk output of the ewes. In particular, pregnant ewes feed three times in the early, middle and late nights, and feed the concentrate, silage, and stalk at the same time in the morning, noon, and evening respectively, which is beneficial to the absorption and utilization of nutrients. Feeding amount and method Adult sheep, usually about 50 kilograms in weight, need to supplement 1.5 to 2 kilograms of hay per head. Supplementary feeding method: After the flock is grazing, it is supplemented with feed, supplement concentrate and chopped root feed, and evenly mixed together, then add salt, stone powder, first sprinkled in the feed tank, and then put the sheep into the circle for feeding. The pregnant ewes replenished 1.5 kg of hay each day, 1.5 kg of silage, and 0.5 kg of concentrate. Nursing ewes feed 0.5 to 0.7 kg of concentrate per day, 1.0 to 1.5 kg of hay, and 20 kg of juicy feed. In addition, urea can be used as a nitrogen-containing additive for supplementing winter grass with insufficient protein content of forage grass. It is best to mix with sugar feedstuffs. Feeding amount is 6-8 grams per day on average, and it is not suitable for feeding to prevent poisoning. .
