The objective of grading up is to produce progenies having 50 to 75% of exotic blood followed by inter-breeding and selection to fix desired characters in new breeds containing exotic inheritance between 3/8 and 5/8. Simple grading-up involves mating animals of two breeds (one to be improved and the other to do the improving). The native breeds of many species of livestock have very low genetic potential for production. 1. Increased reproductive failures, fewer offspring.
