Abstract
The prostaglandins (PGs) have been isolated through an acid-ether extraction of ram seminal plasma and thin layer chromatography. The concentration of PGs was analyzed spectrophotometrically A significant increase in the amount of PGE (E1, E2 and E3) was found at the height of the breeding period due to the increased sexual activity of rams. No changes in the concentration of PGA (A1 and A2) and PGB (B1 and B2) were observed. There was no correlation between the concentration of prostaglandins and the volume of the ejaculates, number of or motility of spermatozoa. The addition of PGE2 and PGF2α to the diluted ram semen in amounts comparable to the total amounts of PGs in one ejaculate increased the fertility of rams by more than 15%. Copyright © 1977.
