title: Characteristics according to productive and genetic characteristics of brown Swiss high-yielding cows
abstract: The most important economically useful signs are presented with an analysis of the genetic structure of 24 brown Swiss cows, milked in the Druzhba breeding farm to record milk productivity from 10 000 kg to 12 100 kg of milk for 305 days of lactation. The record holders, compared with the mothers and cows of the herd, were more precocious, superior in live weight, milk yield, milk fat yield, and productive longevity. Maximum lactation was shown after 2-6 calving (on average 3.5) – 0.6 later than
