Abstract
Extenders for spermatozoa are obtained from porcine seminal plasma and are useful in connection with increasing motility and fertility of porcine sperm as well as extending the useful number of treatments of a sperm-containing solution. Additional extenders are selected from the class consisting of a pyruvate and an oxaloacetate. Another extender having a physiochemical effect can be admixed with the oxaloacetate, pyruvate and/or porcine seminal plasma extenders and can have a synergistic effect therewith.
