This week, New York lawmakers introduced legislation that, if passed, would ban the unnecessary tail docking of dairy cows. The bill was drafted less than a week after animal-rights group Mercy For Animals (MFA) released an undercover investigation into the cruel conditions dairy cows are subjected to at Willet Dairy, the largest dairy farm in New York state. The new legislation was announced on Monday by MFA, and several other animal-rights groups have already applauded the measure. Last September, California banned the tail docking of dairy cows. If the new bill passes, New York will be the second state to outlaw this practice.
