1, we need to see if cows have mastitis first. Breastfeeding can be treated without breast inflammation. When suffering from mastitis, calves should stop breastfeeding, and calves can be artificially breastfed or replaced with other cows. After mastitis is cured, calves can breastfeed with cows. The treatment of mastitis in dairy cows is to squeeze bad milk out of the breast several times a day, then wash the breast with normal saline, and finally infuse the breast with Ding Shuang injection and Lincomycin injection. Dairy cows with serious illness should also be combined with systemic anti-inflammatory treatment.

2. Cows don't have breast inflammation, and their nutrition can keep up. In this case, some Chinese herbal medicines can be used to boil water for cows to drink, such as medulla tetrapanacis, Fructus Passepartout, Semen Vaccariae, leakage reed, corn stigma and so on.

3. Cows are emaciated and malnourished after delivery. In this case, the proportion of feed (soybean meal, bean cake, alfalfa, etc.) in protein. ) to green and juicy feed (fresh grass, carrots, etc. ) can be increased in the diet, and cow mother premix and sheep peptide treasure must be added at the same time. As long as the cows eat comprehensive and balanced nutrition, the lactation of cows will return to normal in a few days.

4. In the case of little milk, calf needs artificial lactation or assisted artificial lactation. Artificial breastfeeding can use fresh milk or calf milk powder, and the milk source must be fresh without deterioration. When feeding, heat it to about 40℃, and then feed it to calves regularly and quantitatively. If there are cows with good lactation performance produced at the same time in the dairy farm, other cows can also be used instead of milk. Before milk replacement, it is necessary to apply some feces and urine of lactating cows to calves, and at the same time apply some essential balm around the nostrils of lactating cows. After several times, the cow will accept the calf that needs to be changed.

5. Calves 10 days old can be fed, and some sweet granular materials can be selected for feeding, and fast-growing premix can also be selected for feeding calves. Generally, calves can learn to eat after calf 15 days old, and then gradually increase the feeding amount of pellet or concentrate. Calves can eat concentrate 150~200 grams every day after 20 days of age.
