Analysis was done for age at first calving (AFC), number of services per conception (NSPC), days open (DOPN), gestation period (GP), and calving interval (CI). The results revealed that the AFC, NSPC, DOPN, and CI of crossbred cows (MO×HO) were significantly lower than those of pure HO cows. GP was numerica… Show more
