Biological and productive features of black-motley cows with various milking techniques

The research was carried out at an enterprise in the Sverdlovsk region. Two groups of black-motley cows were formed: the first including cows of free stall housing with a robotic milking system; the second having tied cows that were milked into the milk pipeline. It was found that udder measurements of animals of the first group had greater values than those of the second group.
