Sperm Characteristics in Cryopreserved Buffalo Bull Semen and Field Fertility
Semen quality and its relationship to fertility are major concern in animal production. The aim of this study was to assess the relationship between frozen thawed sperm characteristics and fertility following in vivo fertility through Artificial Insemination(AI). Semen samples were collected from four buffalo bulls. Semen volume and sperm concentration appeared to be significantly different (P0...
متن کاملPlasmalogen in ram semen, and its role in sperm metabolism.
Whole semen can be stored successfully under both aerobic and anaerobic conditions, owing to the presence of glycolysable carbohydrate in the seminal plasma. However, if mammalian spermatozoa are separated from the seminal plasma by centrifuging and washing, they can maintain their motility only in the presence of oxygen. From this it has been inferred that when spermatozoa are deprived of fruc...
متن کاملEffect on fertility of sperm motility in pooled Duroc semen
Sperm with reduced motility has reduced fertilizing capacity. If low-motile Duroc sperm is mixed with high-motile sperm, the fertilizing capacity of that dose is equal to semen doses exclusively containing high-motile Duroc sperm. With doses that only contained low-motile sperm, the number of total born piglets per litter dropped by minimum 0.5. Duroc boars were selected on the basis of the per...
