Winter and spring cows feed green feed to increase nutrition and save materials
After 45 days of fermentation, the silage stored in the silo becomes a high-quality feed with a soft texture, a sweet and sour flavor, and rich nutritional value. When feeding silage to dairy cows, it's essential to pay attention to several key factors to maximize its benefits, ensure the health of the cows, and improve milk production performance.
**Feeding Quantity**
The amount of silage provided should be based on the weight and milk yield of the cow. Here are some general guidelines:
1. Lactating cows weighing 500 kg with a daily milk yield of 25 kg or more can be fed 25 kg of silage and 5 kg of hay per day. Cows producing over 30 kg of milk daily may require 30 kg of silage and 8 kg of hay.
2. For lactating cows weighing 350–400 kg with a daily milk yield of 20 kg, 20 kg of silage and 5–8 kg of hay is recommended.
3. Cows weighing 350 kg with a daily milk yield of 15–20 kg should receive 15–20 kg of silage and 8–10 kg of hay.
4. Dairy cows with a daily milk yield below 15 kg can be fed 15 kg of silage, along with about 10–12 kg of hay.
**Feeding Method**
1. Start with small amounts and gradually increase to allow the cow to adapt. Sudden large quantities can lead to excessive acidity in the rumen, which may negatively impact digestion and milk production.
2. It’s important to add baking soda to the diet. Silage lowers the pH in the rumen, increasing the risk of acidosis. Adding 1.5% baking soda to the concentrate helps neutralize acidity, promote digestion, and boost milk production.
3. Always mix silage evenly with hay before feeding. If possible, combine silage, hay, and concentrate into a "total mixed ration" for better results and balanced nutrition.
4. Feed silage 3–4 times a day. This encourages more frequent rumination, which helps buffer stomach acid, improves digestion, and increases nutrient absorption. Feeding only twice a day is not ideal and can lead to digestive issues over time.
5. Avoid feeding frozen silage to pregnant cows, as it may cause miscarriage. Always thaw it before offering it to the animals.
By following these feeding practices, farmers can ensure that their dairy cows remain healthy, productive, and well-nourished. Proper management of silage feeding plays a crucial role in maintaining the overall efficiency of dairy farming operations.
