The key technologies for forage, feed preparation and feeding of mutton sheep
As typical herbivores of the genus Ox, most of the sheep were grazing in the past. Now, in order to protect the ecological environment, it is recommended to feed in captivity. In the northern county of our city, the scale of sheep is large. In the early spring season when grass is lacking, the feed supply is dominated by hay and compound feed. The forage, feed preparation and feeding methods of mutton sheep affect the economic benefits of raising sheep. The key technologies in this area are briefly described below.
First, use ideal forage and feed
The ideal forage is grass, clover, potato leaves, peanut stalks, etc.: Concentrates are corn, bran, bean cake and black beans. After weaning, the sheep feed 0.4 kg of concentrate, 2-2.5 kg of hay, 2 kg of silage, and 0.5 kg of feed for roots every day; we should allow them to eat more grass in the summer, reduce the amount of hay, and then reduce the amount of concentrate; supply bone meal and salt every year. Feeding amounts accounted for 2% and 1% of the concentrate.
Second, hay drying and feeding
1. Drying in the field: Suitable for seasons or areas where there is less rainfall. After the pasture is harvested, pave the ground or pile it into small piles for drying.
2. Dry grass on the stand: When there is more rain in summer and autumn season, grass stands can be used to dry the grass. When the sun is dried, the pasture is loosely piled into a conical or ridge shape, and the thickness is 70-80 cm and it is 20-30 cm from the ground. Ventilation, grass racks must have rain protection facilities; general drying time is 1-3 weeks.
3, brown hay modulation: suitable for the rainy season, the pasture will be dried to a water content of about 50%, layered code åž›, åž› 3-5 meters high. During the stacking process, salt (0.5% to 1%) of the total amount of forage grass is added in layers (for moisture protection), and compacted layer by layer to increase the temperature by using forage grass to evaporate part of the water. After 1-2 months, turn it over and let it air dry.
4. Feeding: High-quality hay is suitable for whole-strain feeding or crushing followed by feeding with concentrates.
Third, the treatment of straw feed
1. Crushing method: Straw crushing can improve palatability and reduce waste. Can be mixed with concentrates.
2. Fermentation method: Using microorganisms to decompose cellulose in straw through fermentation to improve nutrient content of straw and increase crude protein content.
3, ammoniation method: the use of liquid nitrogen, uranium ammonium, ammonium bicarbonate and ammonia, under the conditions of the straw ammoniated.
4. Silage method: Corn stalks that have just been harvested for corn ear are suitable for silage. The silage method is similar to the ammoniation method.
Four, root block feed modulation and feeding
Rootstock refers to roots, tubers or fruits. This type of feed is characterized by its high moisture content, soft texture, rich sugar content, easy digestion, good palatability, and vitamins. It is an important feed for winter feeding. After harvesting rhizome feed, it is generally used for indoor storage or cellaring. Before storage, it can be air dried to remove surface moisture. Roots and stems should be washed before mixing and mixed soil. Avoid using the whole rootstock to feed sheep, so as to avoid esophageal obstruction.
Fifth, the preparation and feeding of concentrate feed
The concentrate feed mainly refers to food, cake, and animal protein feed. Its processing method is mainly used for feed supplementation after crushing. The refined feed requires a variety of food and cakes. Do not feed too much, otherwise the sheep will get sick easily.
