Experience and perspectives of cross-breeding in milk cattle husbandry

Abstract

The purpose. On the basis of world experience to show the role of cross-breeding for justification of mercantilely attractive alternatives of crossing in programs of selection of domestic dairy breeds of cattle. Methods. Historical method, use of analytically compared empirical data gained by experimenters worldwide concerning effect of crossing dairy breeds. Results. Recommendations are diven for further improvement by selection method owing to use of crosses of domestic breeds (Ukrainian red-motley and Ukrainian blackmotley milk). Conclusions. Rigid market conditions demand quick search and justification of more efficient programs of selection in cattle husbandry. The availability of crossing genetic differences at dairy breeds, their mating allows to gain genetic improvement of economically important selection tags, development of economically important productive tags of animals of Golshtin breed using method of mating with “contrasting” breeds. The main effect at mating Golshtin breed with series of European breeds is observed to tags of reconstituting and survival rate of calves. One of directions of such development of domestic dairy breeds is searching optimum alternatives of their mating with the following breeds: Monbelyard, Red Swedish, Red Scandinavian, Shvits, and Jersei.
