The interrelation between the higher nervous activity type of the Kholmogory breed cows and their milk productivity

The presented work is the result of studying the influence of the nervous type of the Kholmogory breed cows on their milk productivity in a free stall housing system. These studies clearly demonstrate the advisability of selecting cows regarding their types of higher nervous activity. The average milk yield of animals with a balanced, strong and mobile type of higher nervous activity was 21% higher than in other animals which will make it possible to form more productive herds and increase milk production.
