Sex preselection of sٍheep embryo by altering the minerals of maternal nutrition.

Several methods have been conducted for embryo sex preselection, which includes X- and Y- sperm separation, changing the pH of the female reproductive tract, time of mating before or after ovulation, and feeding formula, such as altering the presence of minerals in diet content before breeding may affect the embryo sex preselection ratio. In this study, three food formulas to feed female sheep were created with the cooperation of the Arabian Agricultural Services Company (Arasco). Ewes were fed with modified food formulas for one month before mating with males.
