Effect of Oxytocin, Cloprostenol or Buserelin in Semen Doses on Sow Fertility

The adjuvant effect of oxytocin on GnRH analogue buserelin.

The mucosa of the nasal cavity has relatively high premeability for peptides. Because of the digestive peptidase activity of the gut, the nasal pathway is currently the route of choice for nonparenteral administration of many peptides including gonadotropin releasing hormone analogues (GnRH-a) . Nevertheless, the transmucosal route of administration may have some problems. Variations exist from...

Influence of postpartum cloprostenol injection on sow and litter performance

nything that compromises sow milk yield would be expected to have a negative impact on piglet performance. Periparturient hypogalactia syndrome has been associated with endometritis.1 Most sow herds have some incidence of endometritis, with reported incidences ranging from 1.1%–37.2% for different herds.2 Recent interest has focused on the postpartum administration of prostaglandin F2α (PGF2α) ...

Effect 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...
