Evaluation of reproductive indicators in black-and-white cows

The article studies the reproductive parameters of black-and-white cows. The animals were divided into groups with light and heavy bodies. The lowest live weight at birth and the live weight of the offspring at the first hotel was in cows with light calving. It was found that in cows with light calving, such indicators as the duration of their own embryogenesis, the duration of the service period, the interbody period, and the value of the coefficient of reproductive ability were significantly lower than in cows with heavy calving.
