The effect of seminal plasma on the quality of coated ram frozen-thawed spermatozoa
Authors
Abstract:
Two experiments were designed to examine the effects of crude seminal plasma (CSP) exposure ofejaculated and epididymal spermatozoa before freezing. Experiment 1, two consecutive ejaculates werecollected (n=4) within 5 min, the second one was carried out in a tube containing Fiser extender (coatedspermatozoa); by centrifugation, seminal plasma was removed from coated ejaculates. The pellets were split into three parts and 0, 50 and 100% CSP (v/v) was added and they were frozen. Samples were thawed and incubated at 37°C for 6 h. The highest progressive motility (10.41%) and the highest hypo-osmotic responses (12.62%) were found for the coated spermatozoa without CSP at 6 (P

Ram seminal plasma increases the fertility of frozen-thawed ram spermatozoa deposited into the cervix. The aim of the current study was to compare the effect of ram seminal plasma to that of bull seminal plasma, dog prostatic fluid, protein-free TALP TrilEq (Triladyl with 0.5 mt of Equex STM paste added to each 100 mt) and heat-treated skim milk on longevity and percentages of progressively mot...

cement is an essential ingredient in the concrete buildings. for production of cement considerable amount of fossil fuel and electrical energy is consumed. on the other hand for generating one tone of portland cement, nearly one ton of carbon dioxide is released. it shows that 7 percent of the total released carbon dioxide in the world relates to the cement industry. considering ecological issu...

Re-suspension of frozen-thawed ram sperm with ovine and bovine whole seminal plasma (SP) is beneficial for its post-thawing viability. However, neither the influence of SP incubation duration nor the re-suspension with equine SP has been tested. In the first experiment, frozen-thawed ram sperm were incubated with SP from bovine (BSP), equine (ESP) or ovine (OSP) or without SP (-SP) for short (5...

در این پژوهش به بررسی اثر افزایش ترافیک بر روی تعداد تصادفات پرداخته شده است. به این منظور 30 تقاطع در شهر تهران بطور تصادفی انتخاب گردید و تعداد تصادفات ماهیانه در این تقاطعات در طول سالهای 89-90 از سازمان کنترل ترافیک شهر تهران استخراج گردید و با استفاده از مدل داده های تابلویی و نرم افزار eviews مدل خطی و درجه دوم تخمین زده شد و در نهایت این نتیجه حاصل شد که تقاطعات پر ترافیک تر تعداد تصادفا...
