Here's why:
* Maternal Instinct: Cows have a strong maternal instinct, but it's primarily directed towards their own offspring. Introducing a strange calf can trigger aggression and potentially lead to the cow harming the calf.
* Scent: Cows identify their calves through scent. A foreign calf will smell different and the cow will likely reject it.
* Lactation: A cow's milk production is regulated by her calf's suckling. A cow who is not the calf's mother will not produce milk for it.
If you're facing a situation where a calf needs a mother:
1. Contact a veterinarian or experienced livestock professional immediately. They can assess the situation and guide you on the best course of action.
2. Consider alternative solutions: In cases where a cow has lost her calf, a foster cow (another recently calved cow) or a bottle-feeding program may be more suitable and safer options.
Safety First: It's crucial to prioritize the safety of both the cow and the calf. Attempting to force a cow to accept a foreign calf is highly risky and can lead to serious injuries or even death.
