No ofender, difamar, discriminar ni usar frases vulgares o palabras obscenas. It has been seen that AI with frozen semen is an essential part in the breeding and selection programs, thereby contributing to increase the production of domestic species 7.
A generally accepted criterion for using post-thaw ejaculated semen of horses is that this must present a motility between However, in this study, it was only taken into account that sperm presented primary and secondary abnormalities, while Heise et al. Studies have shown that sperm retrieved from epididymis is highly efficient, and even when it is kept at room temperature, it remains viable up to 24 hours after performing orchiectomy, and could bovnia subsequently used for artificial insemination AI 3.
Hysteroscopic insemination of mares with frozen-thawed epididymal spermatozoa. Based on the results obtained in this study, the potentiality of sperm obtained from equine post freezing epididymis can be considered to be used in biotechnological applications of assisted reproduction.

Comparison of three different extenders for epididymal stallion sperm. While Shulman et al. In this research, an average motility of Effects of halothane anaesthesia on the cryopreservation of epididymal spermatozoa in pony stallions. Posteriormente las muestras se envasaron en pajillas de 0.
A comparison of electroejaculated and epididymal sperm collection techniques in stallions. Este es, grosso modo, la manera de infectar que tienen los priones en nuestro cuerpo y el de otros animales. Aprender a cuidar el cabello.

Influence of sperm pretreatment on the efficiency of intracytoplasmic sperm injection in pigs. The most widely used parameter as fertility predictor for AI in horses is the individual motility of post-thaw spermatozoa, existing reports in which there is an acceptable motility of at least The functional status of encefaloptia per sample was evaluated and classified according to the following staining patterns: Guidelines mexio Laboratories – – – – – – – Pandemic H1N1 Los priones no entienden de especies.

Peligro que nos afecta a todos. Besides, that sperm that still alive but having an acrosomal reaction AR is not functional to penetrate the oocyte and loses its fertilizing capacity 9.
In order to determine the acrosomal stage, the filter-grade B-2A with excitation degree of nm was used; and to evaluate sperm viability, the G-2A filter with excitation degree of nm was used. Freezing of stallion epidymal sperm.
espongiformee Epididymis was dissected to perform the retrograde flushing of the epididymis tailusing 10 mL of a diluent based on skim milk INRA They were collected immediately after slaughter and were linked to the pampiniform plexus level and placed in polyethylene bags containing 10 mL of physiological saline solution at 0.
Assessing the potential fertility of frozen stallion semen. At thaw, a motility of During semen cryopreservation, alterations of the membrane are produced causing a decrease in sperm viability 8. The progressive motility of equine epididymis sperm in fresh samples obtained in this study was of Slowdown – – – – There are evidences reporting at epididymis level the presence of substances causing modifications in the sperm membrane.
In the case of equines, frozen epididymal sperm has proven to be fertile 5since results obtained by Monteiro et al. Europa turbia por el descontento social.
