Butaphosphan and Cyanocobalamin Supplementation in Semen Extender on Chilled Boar Sperm Quality and Life Span

The effect of antioxidant supplementation in semen extenders on semen quality and lipid peroxidation of chilled bull spermatozoa

The aim of this study was to determine the effects of the antioxidants superoxide dismutase (SOD),glutathione peroxidase (GPx) and butylated hydroxytoluene (BHT) on microscopic semen parameters andlipid peroxidation following the freeze-thawing of bull semen. Ejaculates were collected from five Holsteinbulls and pooled at 37°C. The semen samples were diluted with a CEY extender containing addit...

Oxidoreductive capability of boar sperm mitochondria in fresh semen and during their preservation in BTS extender.

The purpose of our study was to determine the effect of dilution and liquid-preservation of boar sperm on oxidoreductive capability of their mitochondria. The semen was diluted with BTS extender produced from water purified by destillation or by reverse osmosis. The spermatozoa were stored over a four-day period at 16-18 degrees C. The function of sperm mitochondria was assessed using the scree...

Effect of antioxidants added to boar semen extender on the semen survival time and sperm chromatin structure.

The aim of the experiment was to determine the effect of potential antioxidants (adenosine, L-cysteine hydrochloride, ascorbic acid, magnesium fumarate and prolactin) supplementing the Biosolwens extender on semen survival time and sperm chromatin structure. The semen motility was examined every day and the susceptibility of sperm chromatin to denaturation was evaluated on collection day and da...

Effect of L-Carnitine Supplementation on Boar Semen Quality

Jacyno E., A. Kołodziej, M. Kamyczek, M. Kawęcka, K. Dziadek, A. Pietruszka: Effect of L-Carnitine Supplementation on Boar Semen Quality. Acta Vet Brno 2007, 76: 595-600. The effect of addition of L-carnitine on boar semen quality was studied in 5 Pietrain boars at age 1.5 2.0 years. The boars received 500 mg of L-carnitine per day for 5 weeks. During this period, their ejaculates were collecte...
