1. Ensure feed quality. High-quality silage is greenish green or yellow-brown. The smell is savory and the texture is soft and moist. The veins and villi on the stems and leaves can be seen. Poor quality sticks together, indicating that more water; some loose, dry, hard texture, indicating less water. When you use silage, you must use high-quality feeds. Black or dark brown in color, odor in acid, even musty, rot, and deterioration should be discarded immediately. Do not feed dairy cows.
2. Scientific access to feed. When taking silage, it must start from the end of the silo, according to a certain thickness, layered from top to bottom, to prevent mixing of the soil, should not be dig from a hole. It is advisable to take the amount of each day for feeding one day. After the silage is taken out, the silo pool opening must be closed immediately to prevent the silage from deteriorating due to contact with air.
3. Grasp the amount of feed. Silage has a certain sour taste, and some cows may not be accustomed to the initial feeding. They should follow the principle of gradual and gradual progress. The hay can be placed on the upper layer and the silage on the lower layer can be fed on an empty stomach to allow it to gradually adapt. In general, calves are fed silage after weaning. The daily feeding amount of silage for adult dairy cows is preferably 20-25 kilograms, and the range for post-weaning calves is 5-15 kilograms.
4. Pay attention to scientific collocation. Although silage is a kind of high-quality roughage, it must be scientifically matched with the fine material according to the actual needs of the cow during feeding to increase feed utilization. Dairy cattle concentrates and silage (water content) feeding ratio is reasonable in the range of 1:3 to 1:3.5. If silage acidity is large, 5% to 10% baking soda or 1% to 2% lime water can be added to the feed, rinsed and fed to reduce acidity, improve palatability, and promote digestion and absorption.
