Productivity characteristics of Montbeliard breed cows in the conditions of Uzbekistan

Abstract

In recent years, Montbeliard cattle have been imported to France from Uzbekistan in order to strengthen the breeding base of cattle and create high-yielding herds and increase livestock production. However, the productivity characteristics of cattle of this breed have not been studied in our hot climate conditions in special studies depending on various factors. Studies have shown that the level of milk yield of co-breeding Montbeliard cows imported to Uzbekistan depends on the type of production. It was found that the milk yield of lactating cows is 672.5 and 958.5 kg higher than that of dairy and meat-milk cows, respectively, and the level of feed coverage is higher than that of dairy products. It is based on the fact that the milk yield of cows also depends on the biomass index and service life. It was found that cows with a biomass of 531-550 kg, typical of the milk type, produced high milk yields. The level of milk productivity of cows is inextricably linked to the service life. Dairy cows with a service life of 81-90 days are characterized by high milk content, milk fat consumption and 4% milk yield. The selection of cows for the optimal service life is an important factor in the creation of productive dairy herds.
