Dairy productivity and the reproductive functions of cows after feeding of protected choline by it
The cows of Black and White Holstein breed (early lactation) were divided into 2 groups: control (group 1) and experimental (n=35). We used protected form of choline at 1.0 g per kg of milk in the experimental groupe. The experimental data on testing 1 g/kg of milk dose using greater num- ber of animals (n=35) showed an increase in the milk production on 7%. We recommend supplying 1 g protected choline per kg of milk of cows in period after calving.
