Small Tail Han Sheep Overwintering Feed Reserve
In order to ensure safe wintering for the Tail Friesian sheep, sufficient forage must be stocked. The amount of stored forage material varies from place to place. The exact method should mainly be based on the shepherding amount of various sheep, the composition of the ration of each sheep, and the length of the feeding period. The quality of the feed should be determined, and 10% more room should be set aside than actual needs to prevent feed shortage due to special circumstances such as bad weather, lack of grazing and other reasons, which can result in prolonged feeding period, as well as forage quality. . Pasture reserves For sheep, regardless of physiological characteristics or economic accounting, grasses are more important than concentrates. There are mainly pastures, weeds, crop stalks, and leaves. Forage should be timely harvested to ensure quality, such as soybean meal should be in the budding period - early flowering period, the camptotheca herbage should be timely harvested in the heading period, delayed harvest protein content decreased, crude fiber content increased, the quality decreased. During the process of drying, transporting and stacking hay and straw, attention should be paid to the preservation of leaf volume. Grass and leaves have 1-1.5 times more protein and minerals than stems, 10-15 times more carotene, and 50-100% less cellulose, and 40% higher digestibility. The color of hay and straw is an important basis for judging its quality. The greener the color, the higher the quality. If it is yellow or orange, the quality is significantly reduced. After harvesting and drying, the pasture and straw must be transported to the storage grassyard for storage. In the field and on the roadside for a long period of time, the wind, sun, and rain, the oxidative decomposition of nutrients, the quality is poor, and even mildew can not be fed. Small Tail Han sheep have large individuals and fast growth, and the ewes produce more lambs, so they have large feed intake. Adult male and female ewes can be bred at 2.5 kg per day, 2 kg of rams, 1.5 kg of ewes, and 30 kg of lambs for three months to calculate forage stocks. If grazing conditions exist, grazing herbivores should be subtracted. Succulent feed reserves The winter sheep's juicy feed consists mainly of silage, roots, tuber feeds, and melons. The common characteristics of these feeds are their high nutritional value, good palatability, high digestibility, and long shelf life. Solve the shortage of vitamin feed in the winter subtilis period, increase the activity and production performance of the sheep. Some also contain more dry matter and energy, which can replace roughage and concentrate feed, and reduce the amount of forage and concentrate feeds, such as 4 kg of silage or 2 kg of semi-dry silage equivalent to 1 kg of hay, 3-4 Kilograms of sweet potatoes can replace 1 kg of fine material. The type of vitamin that is relatively easy to lack in winter for small tailed sheep is VA, and carotene in feed can be converted to VA. The main varieties of succulent feeds containing higher carotene include silage grass, silage corn, corn stalk silage, carrot, sweet potato, pumpkin, beet, and Gannan. Succulent feed reserves, adult male and female ewes daily by 1.5 kilograms, bred ram, fattening sheep by 1 kg up and down, breast-feeding lamb 3 months lactation period calculated by 25 kg, to meet the needs. Concentrate Reserve Sheep's concentrate feed mainly includes energy feed and protein supplements. The energy feed is characterized by high energy content of crude fiber, good palatability, high digestibility, crude fiber content above 18%, and digestive energy at 2,500 kcal. The above is mainly used to supplement the deficiency of the energy level of the diet. The main varieties are cereals and their processing by-products. The varieties include corn, barley, wheat, oats, buckwheat, millet, sorghum, rice, wheat bran, rice bran and so on. Among them, corn is the first choice for planting, high yield, high energy content, and contains a certain amount of cryptoxanthin, which can be converted into VA. The amount of energy feed supplement depends on the quality of roughage and the sheep's production level. When the quality of forage grass and silage is good, it can be fed less; when the quality of straw feed or pasture is poor, it should be fed more. The ram breeding period, ewes should be fed more during the late pregnancy and lactation. In addition to protein supplements with good palatability, high digestibility, and high energy content, protein content in dry matter is above 20%. The main products include legume seeds and oil cakes, which include soybeans, black beans, peas, beans, bean cakes, peanut cakes, and cottonseed cakes. Among them, the cottonseed cake (粕) contains gossypol toxin, should pay attention to virus-free feeding and limited feeding. Protein supplements are mainly used to balance the deficiency of protein levels in rations. When the content of leguminous herbage in the diet is high, they should be less or no supplements. When grasses or straw are used as roughage, they should be in accordance with the nutritional needs of various types of sheep. With protein supplements to balance the deficiency of dietary protein. Small Tail Han sheep concentrate stockpiles, species of rams by 1.4 kg per day, 0.7 kg breeding ewes, bred rams 0.8 kg, bred ewes 0.5 kg, fattening sheep 0.8 kg, lambs 3 months breastfeeding total 10 kg calculation Yes, among them, cereals such as corn, barley, millet, etc. should account for 50-60%, feeds such as wheat bran and rice bran should account for 15-20%, and protein supplements should account for 30%. In addition to storing and storing self-produced feed, if it is necessary to purchase from outside, in order to reduce the occupation of pressure and prevent the long-term storage and oxidation of cake bran feed, temporary purchase can be made in advance.
