Abstract

The article analyzes milk productivity, milk composition, and the characteristics of lactation in Montbéliard breed cows of various productivity traits. According to the results, the milk productivity of Montbéliard breed cows belonging to group I (milk-meat orientation) in lactation III was 5251.3, which is 705.0 kg or 15.5% (P<0.01), milk fat yield 27.8 kg or 15.0% (P<0.01), protein yield 26.7 kg or 16.3% (P<0,05), 4% milk content 695.1 kg or 15.0% (P<0.001), and milk yield coefficient 141.9 kg or 18.1% (P<0.001) higher than their peers in group II (meat-milk orientation). It was also established that the milk yield per 100 kg of live weight in dairy-meat-oriented cows, i.e., the milk yield coefficient, was 141.9 kg (18.1%) higher than in dairy-meat-oriented cows (Group II).

The cows in all groups maintained good milk yields until the 4th month of lactation, after which a steady decrease in this indicator was observed. The results obtained showed that during the lactation period, dairy-meat-oriented cows, along with high milk productivity, also possessed the property of uniform lactation.
