Prikhodko M. Estimation of productivity and technological properties of milk of newly developed livestock breeds and types in the north-eastern region of Ukraine

The object of researches is Forming of genetic potential of productivity and high-quality indexes of milk at the animal accrued breeds of cattle, which conduct in the conditions of north-eastern region of Ukraine. The purpose of researches is the Complex study of productivity and technological properties of milk of cows of the Ukrainian brown milk breed and Sumy intrabreed type of the Ukrainian black-pied milk breed. The methods of researches are zootechnicss, physical, mathematical, biological, microbiological analysis, economic, statistical. Results of researches: 1. For a theory - complex research of productivity and technological properties of milk is First conducted, accrued to Ukrainian brown milk and Sumy intrabreed type of Ukrainian cherno-ryaboy milk breeds in relation to the paternal and linear belonging. First definite technological correlations of basic components in milk of cows; high-quality composition of fats and albumens of milk is explored. 2. For practice - the Got results can be used for the improvement of productivity and technological properties of milk of the Ukrainian brown milk breed and Sumy intrabreed type of Ukrainian cherno-ryaboy milk breeds which divorce in the north-eastern region of Ukraine.
