Влияние жвачных процессов на молочную продуктивность коров разных пород

Abstract

The article presents the study results concerning the breed traits of ruminant processes in cows in the first lactation period. It was established that under equal feeding and housing conditions, the Holste in cows have an advantage: the duration of rumination compared with Ukrainian Black Pied and Ukrainian Red Spotted dairy breeds. This is reflected in the level of the average daily milk yield. Among the studied breeds, Holstein cows recorded the highest level of daily milk yield (44,9±4,57 kg): by15.1 kg more (Đ>0,95) compared with the Ukrainian Red Spotted breed and by 13.7 kg more (Đ0,999) recorded by the cows of Ukrainian Red Spotted dairy breed.
