After lactating cows, the amount of milk increased rapidly after delivery, peaked at 7 weeks to 9 weeks, but dry matter intake peaked at 10 weeks to 12 weeks. In the early stages of lactation, milk production and dry matter intake of lactating cattle cannot be balanced. Therefore, in this period, the most important thing is to regulate the feed formula of dairy cows reasonably. Basically, it starts to increase the concentrate feed in the late period of dry milk, and then replaces it with feeds with higher nutritional value after delivery, increasing the amount every 2 days to 3 days. the amount. However, feeding too much concentrated feed causes a drastic drop in the pH of the first stomach of the lactating cow, causing a metabolic disorder called "rumoric acidosis," resulting in loss of appetite and hooves. Starting from the fourth month after delivery, it is necessary to properly adjust the feeding of concentrate feed according to the reduction of milk volume, and it should not be too much or too little. If the feeding amount is too much, the cow will be over-fed, increasing the chance of getting sick after the next delivery, reducing the milk production capacity, and affecting the breeding. Therefore, we should avoid the practice of making cows fat when the milk volume begins to drop and returning the cows to thin again during the dry period. Conversely, feeding too little causes the cow to be very thin and it is difficult to recover. Therefore, during this period, it is necessary to pay attention to the rational adjustment of feed concentrates so that the cows can reach the optimum level during the next peak of lactation.
