The proper selection of males for reproduction is crucial to enhance the efficiency and producitivy of the flock. Generally the rams are assumed to be reproductive efficient, and nevertheless, recent studies show that approximately 18% of the rams show physical and/or physiological problems. The identification of those defficiencies is therefore important to discard those rams for reproduction. MSD has developed a drawer to place the ram in, and keep it immobilized in order to collect a semen sample. The quality of the semen sample can be assessed on farm with a microscope and then, farmers can decide upon the results achieved wether to keep the ram for reproduction, or not.
