Choice of the exotic breeds to be used in breeding programme usually depends upon the purpose of crossbreeding. In case of dairy cattle, selection of exotic breeds depends upon its milk production, early maturity, and compatibility with local breeds. Because crossbreeding dilutes the gene pool of the indigenous breed, the exotic breed should provide clear advantages over the performance of the native dam breed. In beef cattle, even though body weight is mostly considered to be a trait of economic importance for breeding objective, size of the exotic breed to be used in crossbreeding programme should not be too. | A Science Roadmap for Food and Agriculture Prepared by the Association of Public and Land-grant Universities A P L U Experiment Station Committee on Organization and Policy ESCOP Science and Technology Committee November 2010 About this Publication To reference this publication please use the following citation Association of Public and Land-grant Universities Experiment Station Committee on Organization and Policy Science and Technology Committee A Science Roadmap for Food and Agriculture November 2010.
