After feeding calves with less feed, the breast often has edema. In this case, only a small amount of concentrate can be fed. After 4-5 days postpartum, the cows began to give a small amount of succulent feed. As the breasts became swollen and soft, the amount of succulent feed was gradually increased until it reached the standard dosage (usually 7-15 days). In the second lactation month, the lactation peak of dairy cows can give full play to their lactation capacity. During the milk rising period, they can give more nutritious feed as much as possible, until the amount of milk no longer increases (approximately 10-15 夭). This part gives more feed.

Provide enough water to allow cows to drink freely. Normal cows need to drink 50-70 kilograms a day, and high-yield cows need more than 100 kilograms.

The supply of salt is generally supplied at 5 grams per 100 kg of body weight. In addition, 2 grams of salt is added per 1 kg of milk produced. You can also feed 2% of the mixed concentrate feed into the feed.

Diversification of feedstuffs Feeds for dairy cows are first diversified as much as possible, secondly, they must be quantified regularly, and the gradual change must be made when changing the type and amount of feeds. At the same time, we must also observe the feed intake of cattle.

The milk in the breast must not be squeezed dry within 3-4 days after the management of the calving, so as not to cause postpartum paralysis. On the first day, they were squeezed several times, each time squeezing 1-1.5 kilograms. On the second day, they were squeezed for 1/2 of the total daily volume. On the third day, they were squeezed for 3/4 of the total amount, and they were all squeezed out on the fourth day. Pay attention to the protection of the breast, pay attention to observation, find abnormal changes, and take timely measures. Brushing the cow before milking each time can not only promote blood circulation, make humans and livestock friendly, but also guarantee the quality of milk. In the spring and summer season, cattle are given hoof repairs. Keep the cow bed clean and dry so as not to deform the cow's hoof. In the summer, it is necessary to keep the cowshed cool and avoid cows from acting.
