The enzyme preparation influence on the milk productivity of the simmental breed cows in the conditions of Yakutia

The influence of the enzyme preparation (Lesnov’s ferment) on the milch cow milk productivity is studied. The use of Lesnov’s ferment allowed to optimize and to balance the rations of feeding, and increased their biological value. It facilitated the milk productivity increase and the milk chemical composition improvement of the Simmental breed cows in the conditions of Yakutia.
