Effect of Trehalose Supplementation to Semen Extender on Quality of Cryopreserved Stallion Semen

Freezing stallion semen with the new Cáceres extender improves post thaw sperm quality and diminishes stallion-to-stallion variability.

Ejaculates from 7 stallions were split and simultaneously frozen in three different extenders, INRA 96 egg yolk glycerol, Ghent and the newly developed extender Caceres. After thawing, samples were evaluated for motility (CASA system) sperm membrane integrity and early membrane changes (YoPro-1/Eth staining), acrosome integrity (FICT-PNA), and mitochondrial membrane potential (JC-1) (flow cytom...

The Effect of L-Carnitine, Hypotaurine, and Taurine Supplementation on the Quality of Cryopreserved Chicken Semen

The objective of this study was to investigate the effect of L-carnitine (LC), hypotaurine (HT), and taurine (T) on the quality of frozen-thawed chicken semen. Pooled semen samples were divided into seven aliquots (control, 1 mM LC, 5 mM LC, 1 mM HT, 10 mM HT, 1 mM T, and 10 mM T) and subjected to cryopreservation. Postthaw sperm motility was determined by IVOS system and sperm characteristics ...

Effect of platelet activating factor (PAF) supplementation in semen extender on viability and ATP content of cryopreserved canine spermatozoa.

The aim of this study was to investigate the effect of platelet activating factor (PAF) on the quality characteristics of cryopreserved canine spermatozoa. Cryopreserved semen of 5 mixed-breed dogs was treated with different concentrations of exogenous PAF (1 x 10(-3) M, 1 x 10(-4) M, 1 x 10(-5) M and 1 x 10(-6) M) and examined at different time intervals (0, 30, 60 and 120 min). Cryopreserved ...

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...
