Antibiotics are off-limits from birth for organic cows. Organic dairy farming believes that fresh air, sunshine, an organic diet, and holistic care are best to keep cows in tip-top health. That said, organic rules require that a sick cow or calf receive the care they need. If an animal becomes ill, natural and alternative methods are often used for treatment. If organic-approved treatments aren’t successful, farmers can use antibiotics or prescribed synthetic medicine to help the animal return to good health. Milk from cows treated with antibiotics cannot be used for any organic product.
