Genomewide association of male reproductive traits in Aksaray Malakli dogs

Tuncer, Pürhan Barbaros | Büyükleblebici Serhat

Male reproductive parameters are often used for the functional examination and evaluation of predicted genetic values for future aspects. However, these traits are relatively reliable until the measurable effects are expressed on desired traits. Therefore, we aimed to associate the single nucleotide polymorphism (SNP) geno type of the investigated characteristics and reproductive loci. A total of 46 male dogs aredividedintothreeagegroups(I≤3years,n = 19; II 4–6 years; n = 19, and III ≥7years,n = 8). The testis, scrotum and body weight, libido sexualis and ejaculation time for each fraction were monitored as functional traits, while the pH, fractional semen volume, motility, concentration, and abnormal and dead spermatozoa rate were recorded as spermatological traits. The A...

Comparison of Cryoprotective Effects of Lycopene and Cysteamine in Different Cryoprotectants on Bull Semen and Fertility Results

Tuncer, P. B. | Büyükleblebici, S. | Büyükleblebici, O.

The objectives of this study were to compare glycerol and ethylene glycol at different concentrations as cryoprotectants and lycopene or cysteamine (with/without) as antioxidants in Tris extender for bull semen. Twenty-four ejaculates were obtained from three bulls. Each ejaculate was split into four equal aliquots and diluted using both of the Tris extenders with glycerol (5% or 7%) or ethylene glycol (3% or 5%). After that, each extenders were split into three equal aliquots and added using both of the cysteamine 5 mM or lycopene 500 lg/ ml, and control (without additives). The addition of 7% glycerol with cysteamine, 5% ethylene glycol with cysteamine and 3% ethylene glycol with cysteamine groups gave the lowest CASA motility than the other groups. However, 7% glycerol and 7% glycerol ...

P.B. Tuncer, M.N. Bucak, S. Büyükleblebici, F. Kuzugüden, S. Sarıözkan, U. Taşdemir, H. Kinet

The aim of the present study was to determinate the effects of different doses of glycerol and ethylene glycol in Tris extender containing the Trehalose or cystein on post-thawed bull sperm motility and motion charecteristics following cryopreservation.
