Dairy cows rely on the fermentation of microorganisms in their rumen to digest feed. These microbes require a stable and balanced environment to function properly. Feeding practices that are irregular or unbalanced, such as feeding cockroaches (which is not a common or recommended practice), can disrupt this environment, leading to poor digestion and health issues. To ensure optimal rumen function and overall cow health, it's essential to feed a variety of forages and concentrates in a balanced manner, avoiding overfeeding.
Here is a recommended feeding plan:
1. **Silage** – Each cow should receive 20 to 25 kg per day. Silage is an excellent source of energy and fiber, but must be of good quality to avoid digestive problems.
2. **High-quality hay** – Cows that are fed silage should also have access to high-quality green hay, up to 4 kg per day. However, many regions lack fresh hay, so during the grazing season, it’s important to dry and store hay properly. Avoid letting cows eat all the grass at once to maintain a balanced diet.
3. **Root vegetables** – Such as carrots and pumpkins, which have high moisture content. These should be limited to 3 to 5 kg per cow per day to prevent digestive upset.
4. **Fresh grass** – No more than 12 kg per cow per day. Fresh grass is nutritious, but excessive amounts can lead to bloating or other digestive issues.
5. **Rapeseed cake and cottonseed meal** – These protein sources should not exceed 10% of the total feed ration to avoid toxicity or imbalances.
6. **By-products** – Such as beer grains, corn residue, soybean meal, and apple pomace, should be limited to around 10 kg per cow daily. These can be useful supplements when used appropriately.
7. **Concentrates** – The amount of concentrate should be based on milk production. For every kilogram of milk produced, provide 2.5 kg of concentrate. High-yielding cows may need more, but never exceed 12 kg per day. When feeding large amounts of concentrate, increase the number of meals throughout the day to reduce the risk of rumen acidosis.
A well-balanced feeding program not only supports milk production but also ensures the long-term health and productivity of your dairy herd. Always monitor the cows’ behavior, weight, and milk output to adjust the feeding strategy as needed.
