First, choose the ideal forage and feed
The ideal forages include alfalfa, clover, and potato leaves, and the concentrates include corn, bran, bean cake, and black beans. After weaning, the sheep will replenish 0.4 kg of concentrate, 22.5 kg of hay, 2 kg of silage, and 0.5 kg of roots. In summer, they should eat more grass, reduce hay first, then reduce the concentrate; replenish bone powder and salt all year round. The feed amount is 2% and 1% of the concentrate.
Second, hay drying and feeding
1. Dry in the field: Suitable for seasons or areas with less rain. After the pasture is harvested, the ground is flattened or piled up into small piles for drying.
2, drying grass on the shelf: When there is more rain in summer and autumn, grass can be used to dry grass. When drying, the grass will be loosely piled into a conical or ridge shape, 70-80 cm thick, 20-30 cm away from the ground, and kept around. Ventilation, the top of the grass frame should have anti-rain facilities; the general drying time is 1-3 weeks.
3, brown hay modulation: suitable for the rainy season, the grass is air-dried to about 50% water content, layered åž›, åž› high 3-5 meters. When palletizing, layered salt (0.5%-1%) of the total amount of forage (for moisture protection), and tightly layered, using the forage fermentation to warm up and evaporate part of the water. After 1-2 months, turn it over and let it dry naturally.
4, feeding: high-quality hay is suitable for the whole plant feeding or crushing and feeding with the concentrate.
Third, the treatment of straw feed
1. Crushing method: After straw smashing, it can improve palatability and reduce waste. Can be mixed with concentrate.
2. Fermentation method: the microorganisms in the straw are decomposed by fermentation by microorganisms to improve the nutrient content of the straw and increase the crude protein content.
3. Ammonia method: The ammonia is treated with liquid nitrogen, uranium ammonium, ammonium bicarbonate and ammonia water under ammoniat conditions under sealed conditions.
4. Silage method: The corn stalks that have just harvested the ear of corn are suitable for silage, and the silage method is similar to the operation of the ammoniation method.
Fourth, the preparation and feeding of rhizome feed
Rhizome feed refers to roots, tubers or melons. The feed is characterized by high moisture content, soft texture, rich sugar, easy digestion, good palatability and rich in vitamins. It is an important feed for winter feeding. After the roots are harvested, they are generally stored or stored indoors, and can be air-dried before storage to remove surface moisture. Roots and shoots should be washed and mixed before feeding. Avoid feeding the whole roots with roots to avoid obstruction of the esophagus.
5. and feeding of
The concentrate feed mainly refers to grain, cake and animal protein feed. The processing method is mainly used for supplementation by pulverization. The concentrate feed is made of various foods and cakes. Do not feed too much, otherwise the sheep are easy to get sick.
