Effect of various levels of catalase antioxidant in semen extenders on lipid peroxidation and semen quality after the freeze-thawing bull semen
The objective of this study was to evaluate effect of different concentrations of catalase in two extenders on motility, viability and lipid peroxidation bull spermatozoa during semen freezing process. Thirty ejaculates collected from ten Holstein bulls were pooled and evaluated at 37 °C. Pool ejaculated was split into two main experimental groups, 1 and 2. In experiment 1, specimen was dilute...
متن کاملCAFFEINE AS A SEMEN ADDITIVE TO IMPROVE MURRAH BUFFALO (Bubalus bubalis) SEMEN CRYOPRESERVATION
Caffeine was incorporated in egg yolk tris glycerol extender (EYTG) at the time of dilution of Murrah semen at a concentration of 1.0, 3.0 or 5.0 mM. The samples were subsequently frozen. The post thaw progressive motility and live sperm per cent improved signifi cantly (P<0.05) with addition of 1.0 (70.0±0.99 and 88.80±0.84) and 3.0 mΜ (65.83±0.88 and 86.16±0.96%) caffeine to the extender befo...
متن کاملProtective role of glutathione in buck semen cryopreservation
The aim of this study was to determine the effect of low levels of glutathione on post-thawed buck sperm quality. In this experiment, different concentrations of glutathione [0 (LG-0), 0.5 (LG-0.5), 1 (LG-1), 1.5 (LG-1.5), and 2 (LG-2) mM] were added in a soybean lecithin-based extender. A total of 16 ejaculates from four bucks were collected and pooled. Each pooled sample was divided into five...
متن کاملSeminal Plasma Heparin Binding Proteins Improve Semen Quality by Reducing Oxidative Stress during Cryopreservation of Cattle Bull Semen
Heparin binding proteins (HBPs) are produced by accessory glands. These are secreted into the seminal fluid, bind to the spermatozoa at the time of ejaculation, favour capacitation, acrosome reaction, and alter the immune system response toward the sperm. The present study was conducted with an objective to assess the effect of purified seminal plasma-HBPs (SP-HBPs) on cross bred cattle bull sp...
متن کاملHigh dilution rate of bull semen affects cryopreservation outcomes: kinematic and flowcytometric parameters
BACKGROUND: Semen cryopreservation might be influenced by sperm concentration. OBJECTIVES: This study was conducted to investigate three different semen concentrations [100 (C100), 50 (C50), and 25 (C25) × 106 spermatozoa/mL] on freezability of bull semen. METHODS: On each collection day, four ejaculates were collected (a total of 24 ejaculates from four bulls), pooled and divided to three equ...
