Effects of storage duration at 5 ºC and type of cryoprotectant on cooled and frozen-thawed ram epididymal spermatozoa
Freezing of ejaculated and epididymal spermatozoa is currently a subject of interest with the purpose of establishing an efficient gene banking model for valuable animals or endangered species. Therefore, the present study evaluated the influence of different storage duration )0, 1.5 and 5 h) at 5 ºC and type of cryoprotectant on freezability of ram epididymal spermatozoa. With increasing the s...
متن کاملEffect of Soybean Based Extenders on Sperm Parameters of Holstein- Friesian Bull During Liquid Storage at 4oC
Animal origin egg yolk extender has been associated with microbial contamination and interference with microscopic examination. Therefore, replacement of such extender with plant origin compound is inevitable without compromising the desired qualities of an ideal extender. In the current experiment, we compared the effect of soy-based extender (25% and 50%) of five adult Holstein-Friesian bulls...
متن کاملEffect of transportation temperature on the quality of cauda epididymal spermatozoa of ram.
The objective of this study was to develop a protocol for ram epididymal sperm preservation that could be applied to wild ruminants for collection and preservation of spermatozoa from dead or hunted animals. Ram testicles collected from abattoirs were used to study the effect of two transportation temperatures viz. ambient temperature (AT) and refrigeration temperature (RT) on the cauda epididy...
متن کاملEvaluation of frozen thawed cauda epididymal sperms and in vitro fertilizing potential of bovine sperm collected from the cauda epididymal
In the present study, the fertilizing potential of semen recovered from slaughtered bulls epididymis was evaluated after cryopreservation, by conventional techniques and flow cytometry methods. The cauda epididymal was dissected and sperm were recovered and evaluated for volume, sperm concentration, and membrane and acrosome integrity using a flow cytometer. Sperm fertility potential was tested...
متن کاملEvaluation of Lasting Effects of Heat Stress on Sperm Profile and Oxidative Status of Ram Semen and Epididymal Sperm
Higher temperatures lead to an increase of testicular metabolism that results in spermatic damage. Oxidative stress is the main factor responsible for testicular damage caused by heat stress. The aim of this study was to evaluate lasting effects of heat stress on ejaculated sperm and immediate or long-term effects of heat stress on epididymal sperm. We observed decrease in motility and mass mot...
