Cattle breeders use oxytocin vaccines for weaning. Oxytocin is a hormone used for weaning. The use of this vaccine is totally wrong and extremely harmful. It can lead to serious diseases in cattle. The oxytocin vaccination is bad for the health of cattle. Humans also suffer from various diseases by consuming the milk obtained from them. Therefore, instead of vaccinating, farmers should first free the calves to drink milk and then wean them.
