Dairy cows digest the feed by relying on the fermentation of microorganisms in the rumen. The microorganisms in the rumen need a relatively stable environment. The method of feeding the cockroaches is not conducive to the rumen health of the cows, which is not conducive to digestion. The best way is Feed all kinds of feeds reasonably, and feed should not be fed too much. The specific feeding amount is as follows:
1. Silage. Each cow is fed 20 to 25 kg per day.
2. High quality hay. Cows that eat silage are best fed with high-quality hay (green hay) and no more than 4 kg per cow per day. At present, most areas lack green hay. Therefore, during the grass season, it is necessary to hurry up to dry the hay. Do not let the cows eat all the grass.
3. The root class. Such as carrots, pumpkins, because the moisture content is too high, it is not advisable to feed more, 3 to 5 kg per head per day.
4. Fresh grass. No more than 12 kg per cow per day.
5. Rapeseed cake, cottonseed meal. Do not use more than 10% in dairy feed.
6. Accessories . Such as beer grains, corn residue, bean curd residue, apple pomace, each day should be controlled at about 10 kg.
7. Fine material. According to the ratio of feeding 2.5 kg of milk per kilogram of milk to 1 kg of concentrate, the high yield of milk is more to the concentrate, and less milk is given to the concentrate. However, no matter how high the milk production of the cows, the amount of concentrate can not exceed 12 kg per day, and in the case of large concentrate feeding, the number of feedings is increased to slow the increase of rumen acidity.
