What happens if a cow becomes sick?
The dairyman, like a parent makes a judgement as to whether or not he can treat the animal on his own, if not he calls a veterinarian. If an animal requires antibiotics then the milk from that animal is not used until the antibiotic is cleared from the animal. The prescription for the medicine lists the time necessary to keep this animal out of the milking herd. The milk is tested for anitbiotic residue as a condition of acceptance by the processing plant.
