A: Under normal circumstances, if the cow is not sick, do not use antibiotics. If you do not use antibiotics, it is best to use injection rather than oral. Because cows are polygastric animals, when taken orally, antibiotics kill some of the beneficial microorganisms in the rumen of dairy cows, causing an imbalance in the microbial community in the rumen of dairy cows. Prior to the establishment of rumen microflora in the rumen microflora, it is possible to feed some antibiotics in order to prevent disease and promote growth. When the calf is 7 to 8 months old, do not feed it again. In addition, the number of antibiotics given to cows should be as small as possible. Because cows are timid and very sensitive, injections can have an effect on milk production. Vaccination also affects milk production in dairy cows, especially in hot summer days. Therefore, joint vaccines should be used as much as possible. If the cow's disease is not very serious, it is best to wait until the end of production before treatment, so as not to affect the milk production. At the same time, in the two months after the cows have stopped production, we must strengthen feeding and management, strive to reconcile the cows during the discontinued period, so that the dairy cows can be put into the next round of production with a healthy body condition.
