Evaluation of Different Concentrations of Egg Yolk in Canine Frozen Semen Extender
… concentrations of egg yolk in canine freezing extender void of glycerol, a commonly used cryoprotectant, by examining the motility and morphology throughout the freezing process: initial (baseline after extender added), post-cool (after three hours at 5"C) and post-thaw (after freezing.) …

The combinative effect of soluble suLeA glycan and specialized bovine semen extender, FSRD4+, on bull sperm quality
… of our objectives was to determine if a liquid extender, FSRD4+, could extend the lifespan of sperm by days. Since longevity with minimal sperm damage was an ultimate goal, we also tested the effect on longevity by adding oviduct glycans to medium and extender. Before fertilization and while …

Effect of different disaccharides as energy supplements in tris-egg yolk semen extender on the quality of cryopreserved boer goat spermatozoa
The quality of cryopreserved Boer goat semen may be influenced by the source and concentration of energy supplements in the extender. The aim of the study was to improve the protocols for cryopreservation of Boer goat spermatozoa using different disaccharides concentrations as supplements in tris- …

The Use of Ceftiofur Sodium in the Extension and Cooled Storage of Equine Semen: Its Effects on Motion Characteristics, pH, Osmolality, and Bacterial Growth
During semen collection in the stallion, contamination of the ejaculate occurs secondarily to the normal microflora present on the external genitalia. These bacteria and their metabolites can negatively affect spermatozoal motility and viability during cooled storage. Therefore, the addition of …

Zinc ion fluxes on the pathway to mammalian sperm fertilization competency
… sperm fertilization competency and management of semen storage. Little focus has been placed on other divalent ions, including zinc ion (Zn2+). Further, the ultimate maturation event preparing mammalian spermatozoa for fertilization, sperm capacitation, was first described in 1951, yet its …

Cryopreservation of Domestic Cat Epididymal Spermatozoa
… The objective of this research was to identify a semen extender that contained little to no egg yolk and could still effectively freeze domestic cat epididymal spermatozoa, for the purpose to sort spermatozoa into X and Y, using flow cytometry. In the first experiment we compared a TesT (Tes + …

Effect of Avocado (Persea americana Mill) oil inclusion in the Tris-based extender on the quality of Boer goat semen stored at different temperatures
Semen extenders are chemical mediums used for preserving, and protecting spermatozoa against different shocks while processing, storing and transportation for use in artificial insemination (Raheja et al., 2018). There are challenges with the preservation of goat semen for Artificial Insemination …

Determining the role of nerve growth factor-beta in seminal plasma on bovine reproduction
… physiological mechanisms may become lost. Frozen semen used in artificial insemination is extended to achieve the lowest effective breeding dose and maximize the number of straws acquired per collection. However, this practice also dilutes out the seminal plasma proteins to sub-physiological …
