Can a cow kick backwards

Cows theoretically can become stuck on their back when rolling or if knocked down. If the cow is weak, badly injured, or becomes stuck in a rut after rolling they might be unable to get back on their feet and can die if unassisted.

Another Answer:No, they are more likely to get stuck on their sides than on their backs, though occasionally it is possible if they somehow roll into a ditch or deep rut and get stuck with their legs up in the air. The only way they could "roll"is if they struggle so hard that they end up in worse condition than when they first started. But more often they'll get stuck with their side in a rut in a ditch or rut in such a way that they cannot get their feet back under them again. This happens if a cow has to lay down to calve and lays down in a spot she shouldn't have laid down in the first place.
