Preservation diluents of boar sperm


The statistical model used was. Motility of sperm cell is essential to reach the site of fertilization and to penetrate through the oocyte to form zygote. Semen extenders are used to create multiple insemination doses from a single ejaculate and contain buffers and nutrients suitable for storage of spermatozoa. Survivability of the sperm cells was taken as the average percentage number of motile spermatozoa in each extender recorded during 24 hour storage duration. The percentage of sperm that survived increased as the percentage of the test ingredients honey, sugarcane, tomato, pineapple in each extender was increased from 1. Ejaculates were visually separated into sperm-rich and sperm-poor fractions, but only the sperm-rich fractions used in storage experiments were assessed for volume, progressive motility, sperm concentration, and live spermatozoa using standard laboratory methods. Structural and functional integrity of the sperm outer membrane plasmalemma is essential for sperm metabolism, capacitation, ova binding and acrosome reaction.

Transportation costs to place pigs in new breeding units in other regions of the world are high, risk of disease transmission remains a threat, and health regulations for import or export are difficult and involved.
