Fresh, juicy and protein rich feed

Most of the sheep-raising areas in China have long cold winters and grassy days of about 150 days. Although grazing occurs in early spring and winter, dry grasses have low nutritional value, coupled with severe cold, low grazing and grass production, and high body heat energy consumption. The ewes are in gestation and lactation, and grazing alone cannot meet the nutritional needs of the sheep. It is necessary to grasp the characteristics of the nutritional needs of the mutton sheep at the growth stage, and to ensure a sufficient quantity and a reasonable proportion of the required protein, energy and other nutrients, in order to exert the maximum heritability of the growth of the meat sheep and improve the carcass quality. The feeds used by mutton sheep include green fresh feed, silage, dry roughage, concentrate feed, juicy feed, animal feed, and inorganic salt feed. (A) The green feed has many types of green feed, including wild weeds, shrub shoots that can be utilized, various fruit trees and tree leaves, and cultivated legumes, gramineous grasses, planted corn, and legumes. Straw, seedlings, leaves, etc. The leguminous green feed contains high protein content, such as about 20% of crude protein contained in dry matter, and 1.5 times higher than protein contained in corn and 1 times higher than protein contained in oats. It is the main herbage for sheep's body protein. Gramine green feed contains carbohydrates in addition to protein. Green feed is a major source of vitamins and inorganic salts needed for mutton sheep. It contains more vitamin C, vitamin E, vitamin K and inorganic salts. For the development of mutton sheep, we must pay attention to the cultivation of pasture and the improvement of grassland work to increase the nutritional value and utilization of green feed. Cultivated forage should be based on legumes and grasses. Legumes include grasses, red clover, white clover, grass rhinoceros, red bean grass, wild peas, and Lespedeza. Grazing grasses include bromegrass, Elymus herba, Leymus chinensis, water grass, Sudan grass, ryegrass grass, and Timothy grass, etc. For details, see the “High-yield Cultivation of Forage Grass” and “Grass Improvement Use” of the Golden Shield. Although legume forages have high nutritional value, the fermentable carbohydrates in the grass produce a lot of gas in the rumen of the sheep, which can easily cause rumen expansion. Therefore, in the improvement of pasture, legume forages should be mixed with grasses such as Gramineae and Compositae. (2) Silage silage is chopped and compacted in green succulent feed and sealed in silages, silage towers or plastic bags. The smell produced after lactic acid fermentation is sweet, sweet, soft, juicy, nutritious and easy to use. The preserved feed is an excellent green and juicy feed for winter mutton sheep. For details, see the Gold Shield version of Feed Silage Technology. There are many silage materials, such as crop stalks, especially barley and green corn stalks, which are the raw materials used to make silage. In addition, soybean meal, peanut meal, sweet potato soup, grass weeds, various leaves, vegetable leaves, etc. can be used as raw materials for silage. Leguminous grasses can be mixed with grasses, but legumes should not exceed 30%. (3) Dried roughage Dry green feed is used to preserve the nutritional components of green feed instead of green feed. Green hay and leaves are the best quality feed for the subtilis season. They mainly refer to the green leaves of pasture, weeds, crop leaves, fruit leaves, and tender shoots of arbors and shrubs such as willow, buckwheat, and hedgehog. The content of nutrients in green hay and concentrate feed is relatively balanced, especially the protein of leguminous hay is relatively complete, with more vitamins and inorganic substances. Rugao contains 18 to 25 mg of vitamin K per kilogram. Crude hay includes all kinds of crop straws and stems and leaves, such as straw, wheat straw, and corn stalks. There are gluten, peanut pods, sweet potato pods, weeds, rough hay and so on. This kind of feed contains less nutrients than hay, contains more essential elements, and contains less heat energy. (4) Fine feed concentrates mainly refer to the seeds of grass crops and legumes, such as corn, barley, sorghum, and oats, and beans such as soybeans, peas, and beans. In addition, there are by-products of agricultural product processing such as bran, rice bran, cottonseed cakes, and bean cakes. The concentrate feed has the characteristics of high digestible nutrient content, small volume, low water content, low crude content, and high digestibility. Concentrate feed is an essential feed for meat sheep, especially for winter and spring grass shortage. There are many types of concentrates and contain different nutrients. For example, corn contains 70% starch and has high energy, but it contains less protein, especially tryptophan deficiency. Therefore, if you feed only corn, the sheep will be stunted. The protein content of legumes was 1 to 2 times higher than that of cereal crops, and the content of nitrogen-free extracts was lower than that of grass seeds. If the two types of concentrate feeds are fed together, their nutritional components can complement each other. When using soybeans to feed sheep, there is a problem to note that soybeans contain an anti-enzyme substance that inhibits trypsin action and can reduce the digestibility of protein in the diet. Therefore, the soybeans should be boiled first and the inhibitors should be destroyed before feeding to increase the utilization of the protein. (5) Juicy bait Juicy feed refers to carrots, sweet radishes, sweet potatoes, cassava, potatoes and other root feeds and squash, pumpkin, and other melons. Succulent feed is characterized by high moisture content, low dry matter content, low crude fiber content, high vitamin content, crisp texture, and high digestibility. Such as carrots, sweet potatoes, cassava contains more carotenoids, pumpkins contain more riboflavin, this type of feed is an indispensable feed for meat sheep in winter and spring. (6) Animal feeds Animal feedstuffs include skimmed milk, whey, blood meal, meat residue, meat meal, fish meal, and cocoon. Animal feed is a protein feed. In addition to dairy products, other types of proteins contain 55% to 84%, which is not only high in content but also of good quality. This type of feed contains few carbohydrates and is almost free of crude fiber. Such as fishmeal calcium 5.44%, phosphorus 3.44%, high vitamin content. Both ewes and fattening sheep that are lactating require large amounts of animal protein feed. (seven) inorganic salt and vitamin feed inorganic salt and vitamin feed salt, chalk, gypsum, shell powder, eggshell powder, bone meal, trace elements and vitamins. This kind of feed contains no protein, no heat energy, only contains inorganic salts and vitamins; as an additive, except for salt, it is rarely fed alone, and it is best mixed with the use of concentrate feed.
