It is difficult to generalize or average out the weight of all cattle because different breeds have different averages of weights. Small cows, such as Dexter or Jersey can be as small as 270 kg which implies nearly 4 per ton. On the other hand, single animals of breeds such as Charolais or Belgian Blue can reach a ton.
