Furthermore,among cows that failed

Furthermore,among cows that failed to express estrus,FTAL pregnancy rates when using sex-sorted semen at the delayed time (36%) were comparable (p=0.9) to those achieved using conventional semen at the standard time (Treatment 1;37% ). These results indicate that delaying AL of nonestrous cows by 20 h from the standard FTAL improves pregnancy rates when sex-sorted semen is used with FTAL
