Вміст фосфоліпідів у спермі бугаїв за дії L-карнітину
The changes in the composition of phospholipids in the semen of bulls for the actions of different doses of L-carnitine in their diet were investigated. In bulls semen there were identified that phospholipids fractions of lizophosphatydylholin, sphingomyelin, phosphatidylinositol, fosfatydyl-serine, phosphatidylcholine, cardiolipin, phosphatidylethanolamine and phosphatidic acid. Adding to feed of L-carnitine causes a change in the ratio between different fractions of phospholipids. The probable increase in the relative content of phosphatidylcholine and phosphatidylethanolamine was established. The content of lizophosphatidylholin in semen of research bulls for the entire study period was significantly decreased, which is probably associated with a decrease in intensity of free radical oxidation of phospholipids. L-carnitine has a positive effect on the metabolism of spermatozoa, stabilizing their structure and increasing the protective capabilities of sperm.
