Several sheep feed processing technology

In order to improve the palatability and nutritional value of roughage, the following technologies can be used to treat roughage. 1. Pasture silage technology. Silage refers to the feed that green feed is stored in a closed container and fermented by lactic acid bacteria. Temporary silage crypts may be selected from high-dry topography, hard soil, sunny reach, low groundwater level, well-drained water, and closer to the sheep house. The walls of the permanent silo are to be built with bricks or stones, or they can be built on the ground, with the inner walls being as smooth as possible. Silage method: The silage material is as short as about 3 cm. This length is convenient for compaction and access. When using a silage cutter, short raw materials can be sprayed directly into the pit. Compress the short raw materials and press them tightly, paying special attention to the corners and pits. It is generally used for manual stepping. The faster and tighter the cellar, the better. After filling, a layer of dried stalks can be laid on top of it, and a layer of wet soil about 30 cm thick can be cultivated. If it is covered with plastic film, a layer of wet soil shall be pressed on top and the top of the cell shall be sealed. The tighter the state of containment, the better the effect. Within 3 to 5 days after sealing the cellar, attention should be paid to inspection, and it is found that cracks in subsidence should be immediately filled with wet soil. The cellar top is preferably rounded to prevent seepage into the rain. After more than 20 days to open the cellar access. It is best to start from the lee place. Silage is good in palatability, but succulent is easy to cause mild diarrhea. It should be used in combination with hay or stalks. The amount of silage should be increased from little to large. 2. Straw ammoniation technology. Straw rake with a rake to a length of 3 to 4 cm, placed in the cement pool, lay a layer on the use of sprayer spray urea water once again, and compacted layer by layer, until the cement tank up to 30 cm. The top is covered with a plastic film, and the periphery is pressed tightly with soil. It can be taken after 30 days. Straw was blown out one day before feeding to reduce the smell of ammonia. Generally 100 kg of straw use 5 kg of urea and 40-50 kg of fresh water. After ammoniating of straw, the content of crude protein is obviously increased, but the palatability of ammoniated feed is poor, and it must go through a fairly long adaptation process. 3. Roughage fermentation technology. The crude feed (grain flour, straw powder, etc.) plus 10% corn flour and microbial preparations with decomposed crude fiber were thoroughly stirred well, and about 40% of well water or non-chlorinated tap water was mixed. It is advisable to go to the ground until it is in a clump, then place it in a cement pool and seal it after compaction. After about 7 days, the content of crude protein and crude fiber was measured, and then formulated into a mixed feed according to the nutritional requirements of the sheep. 4. Straw emblem storage technology. Straw rakes are used less than 2 cm shorter, add 0.5% to 1.0% corn flour and mix. 1,000 kg of straw used live fermentation of straw (used according to instructions for use) and 2 grams of molasses or brown sugar. Dissolve molasses or brown sugar in 200 ml of water first, and pour the live dried bacteria into sugar water. Let stand for 2 hours at room temperature to fully rejuvenate the bacteria. Then pour the seedlings into 1200 kg of water and mix well (water temperature and temperature). The minimum must not be less than 10°C.) The straw ammoxidation method is used for micro-storage in the cement tank and can be taken out after 20 days. The high-quality micro-storage straw feed is golden yellow, emitting a fruity smell, soft and moist to the touch, especially for cattle and sheep. Its feeding effect is better than ammoniated straw and its cost is low.
