Almost all feedstuffs needed for house-feeding goats come from artificial preparation and supply throughout the year. Forage fodder stocks are both an important part of the technical support for house-raising sheep, and are the most important components of raising and operating costs under house-fed management methods. Each farmer should combine his own specific production purposes, business models, stockpile investment input capabilities and the actual situation of local feed resources, in accordance with the principle of adapting to local conditions, diverse mixes, balanced seasons, phase supply ingredients requirements, research and development of appropriate reserves of forage materials program. (A) of the sheep's diet, digestive function characteristics and homes sheep feeding the general requirements for forage stock 1, sheep's feed range. Sheep belong to ruminant herbivores and have the most extensive range of forage materials available. According to feeding trials on more than six hundred kinds of plants of goats and sheep, the selective rate of sheep for plants ranks first among all kinds of livestock and poultry, which are as high as 87% and 79% respectively. Natural pastures, shrubs, branches and leaves of agricultural and sideline products, etc. can be used as a sheep's feed, for silage, micro-storage or ammoniated straw also has a good feed utilization and digestibility. In addition, it also has a certain ability to use non-protein nitrogen (such as urea). 2, the sheep's diet, digestive characteristics and general requirements for feed (1) lips and lips, thin teeth, especially the upper lip is flexible and easy to feed, the lower tibial teeth have a certain degree of inclination to feed a very short feed Grass and crush feed. (2) The selective eating habits are mainly based on the appearance of the feed and the odor as the selection conditions, and the different strains of the same plant can be distinguished. Natural plants do not like to eat spiny hairs and waxy lipids, like to eat more protein and less crude fiber forage. In addition, goats and sheep also have different preferences for food selection. Goats generally prefer bushy foliage and short grasses, while sheep prefer broadleaf weeds. (3) Eating grass, drinking clean water, being trampled and contaminated grass will rather hungry than eating. Therefore, it is necessary to store grasses for raising sheep and feed them in a fixed feed trough, so as to avoid waste, drink water in a timely manner, and diligently change the ground. (4) The sheep is a compound stomach (rejuvenation) animal. Due to the digestive action of the rumen microorganisms and the characteristics of the gut, the digestive capacity of the feed is very strong. In particular, the digestibility of crude fiber can reach 50-80%. The proportion of crude fiber in adult sheep's feed should reach 40%, which is suitable for cutting and grinding and processing modulation. The rumen microbial flora of the lactating lamb has not yet formed. The fourth stomach plays a major role. It should be treated like a monogastric animal. It cannot synthesize certain essential amino acids and vitamins. Therefore, the lamb should be fed a high-quality protein diet. And hay containing less crude fiber. (b) Classification and storage of sheep forage materials, processing, preparation, and feeding of forages for keeping sheep, which can be broadly classified as green forage, silage, hay and artichoke feed (including roughage), and concentrate feed (including energy Feed and protein supplements) and other four categories. 2, feed processing modulation method (1) mechanical treatment: including chopped, kneaded, ground, flattened, roast, dry and straw rolled green. (2) Chemical treatment: Including straw alkalization and ammoniation technology. (3) Microbiological treatment: Straw silage and straw micro-storage are common. The following focuses on silage. Silage is filled with fresh feed into a closed silo. After fermentation by microorganisms, it is made into a soft, juicy, fragrant, nutrient-rich and easy-to-store succulent feed for cattle and sheep in winter and spring. It is a good way to store and modulate silage and basically maintains some of the important characteristics of silage. A. Silage is characterized by its soft texture, good odor, and good palatability. All kinds of livestock prefer to eat. Adding silage in livestock rations in winter can not only ensure nutrient supply, but also increase appetite, and because of its pourability, it can overcome the disadvantages of constipation caused by single feeding of gramineous roughage. Silage raw materials are widely sourced and the preparation method is simple. After silage fermentation, feeds with poor palatability and no direct feed can be converted into good feeds. B. There are many common silage materials, but the best is silage corn. C. Silage equipment includes silo and silage. D. Silage brewing method is divided into four steps: harvesting, shortening, filling, sealing cellar harvesting: timely harvesting, gramineous grasses for heading, leguminous pastures for initial flowering or full flowering, corn stalks for milk and stalks Ye Shangqing green period, weeds and other wild plants for the flourishing period. Cut short: In order to facilitate packing, step on food and facilitate the fermentation of lactic acid, and feeding, the silage material must be cut short. The degree of shortening should be different according to the type of raw materials and the feeding target. In the process of shortening, attention should be paid to the water content. The moisture content of silage raw materials is generally controlled at 70-75%, and that of semi-dry silage is 50-60%. Loading: Select fine weather, the best 2 days after storage, filling should pay attention to compaction. Cellar Sealing: The cellar must be tightly sealed, airtight, and water-proof. The raw material should be 50 cm above the cellar. The plastic film should be placed on top of the raw material, and 50 cm thick soil should be covered to seal the cellar. E, open cellar use. One month after fermentation can be used to open the cellar, the use of attention should be paid attention to: cellar mouth best scaffolding shading, to prevent the sun and rain, causing feed mold failure; to avoid feeding the soil mixed into the layer by layer by paragraph Dig up; often check the moldy feed, each time the amount taken depends on the amount of feed, with the use of access, take the material after the cover material surface, so as not to freeze or fall into the soil to cause waste; the amount of feed should not be too much at the beginning, Should not be a single feeding, pregnant mothers and animals should not be fed, so as not to cause miscarriage. F, silage quality appraisal. Good silage should be of a color close to the color of the raw material, and the smell is acid and aroma. It is very tight in the silo, and it is loose on the hand.
