At present, the dairy industry in Dali Prefecture is rapidly developing, and the number of dairy farmers and specialized households is increasing. Practice has proved that if we want to raise our cattle well and raise the economic benefits of raising cattle, we must allow the cattle to eat green fodder in addition to summer and autumn. Doing a good job of silage work is the best way to solve this problem. Entering July is the golden season for feed silage. In the past silage work, some farmers had unclear or poorly understood the technical aspects of the silage process, resulting in the unsuccessful production of silage, resulting in greater losses. To this end, the silage technology is introduced as follows:
1. Making Silage Silage is to cut the crop stalk (corn stalk, etc.) in fresh green and green, properly dry, until the water disappears to about 70-80%, cut into pieces of 3-4 or so long, each 100 kg add 2% (ie 2 kg) of salt, mix well and fill in a closed silo. During the filling process, pay attention to each layer of compacted layer, each layer is about 20? If the air in the silo is discharged, if you feel that there is more water in the process of stirring, you can add bran feed to mix water so that the water is not too much. After the feed is completely filled in the silage vessel, it is sealed with a plastic film. If the silo is too large, the membrane is tightly sealed with mud. After more than one month of microbial fermentation, the resulting feed is silage. This feed basically retains the original green, juicy, nutrient-rich characteristics of green feed. The main advantages of silage include: (1) The source of silage materials is abundant, and crop straws (such as corn stalks, etc.), various weeds, grasses, sweet potatoes, leaves, etc., can all be silaged. (2) Silage is rich in nutrients. During the production, the whole straw (including stems, stems, and leaves) can be used for silage, and the green and leaves of the straw can be preserved. Therefore, most (85% or more) of the nutrients in the crop stalk can be preserved, and the loss of crude protein and carotene is also small (usually green feed loses 30% to 40% of nutrients after drying, and almost all of the vitamin is lost). (3) Because silage is soft and juicy, smells sweet and sour, has good palatability and is suitable for feeding cows. Dairy cows also like to eat; and they can promote the secretion of digestive glands and have a good effect on improving the digestibility of feeds. . (4) The silage production method is simple, low-cost, not subject to weather and season restrictions, and the nutritional value of forage grass can be preserved for a long time (years) without change. It can meet the needs of dairy cows to feed the green and green feed in winter and spring (or year-round). (5) Silage can make full use of the rich forage resources in the region, especially feeding large amount of corn silage silage to beef cattle, which can greatly reduce the waste of corn stalks.
2. Use of Silage The silage fermentation can be used for about one month. Production generally only requires sensory evaluation. Once the silo is opened, it should be taken every day. When it is used, the cellar should be opened in sections and used in sections. Each section should be taken from the top to the bottom. The rectangular cellar should not be fully exposed, and it should be used horizontally to avoid waste. And silage deterioration. When using in a segment, do not pry holes. After the collection, covers such as plastic film and straw curtain should be timely covered. If it is raining during use, it should be covered with plastic cloth to prevent rain.
1. Check the quality, color, aroma, taste and texture before feeding. High-quality silage corn stalks should be: yellow-green color, soft and juicy, savory and acidic, good palatability, and with a strong wine flavor.
2. When feeding, the silo can only be opened one by one. Open the cellar in sections and take it layer by layer. Cover it well after it is taken to prevent sun exposure, rain and secondary fermentation, and avoid loss of nutrients, quality degradation or mildew. Deterioration. If you find abnormalities can not be used.
3. When silage corn stalks are started to be fed, the number of silage corn stalks must be gradually increased. When feeding is stopped, the feeding amount should be gradually reduced so that the cows have an adaptation process. Prevent sudden changes in feed, causing the appetite of dairy cows to decline.
4. Silage is a good feed for dairy cows, but it cannot be fed for a long period of time alone. This not only makes it difficult to ensure the demand for nutrients from dairy cows, but it also causes diarrhea due to large amounts of feeding, especially for pregnant gravid animals, not to feed silage alone. .
5. The amount of silage used can generally be used as the sole roughage. Usually cows 12-20kg. High-yielding dairy cows are required to properly add quality hay.
