[Feeding of milk from cows with diseased udders to calves from the viewpoint of public health].
Milk that cannot be brought to the market is often given to calves. While some authors recommend avoidance of the feeding of such milk, others do not see problems related to their use if this milk is treated and supplemented correctly. When altered milk is fed, the producer of calves is responsible for the risk that the calf could contract a disease and to a lesser extent that the health of the consumer of veal could be endangered. Because the owner of the calves is responsible for the risk associated with the feeding of altered milk, he should be informed on the danger and consequences. The consumer whose wishes control the market wants a product that is free from bacteria and drugs. Therefore, the necessity exists for the implementation of similar withdrawal times for the use of altered milk in calves. Two questions related to public health are asked to the veterinarians:how long the flora of the gastrointestinal tract of the calf remains affected after feeding of altered milk and how long antimicrobials can be detected in the edible tissues of the calves? If these questions are answered, guidelines for the use of mastitis milk could be used.
