Effects of Differing Gentamicin Concentrations in Semen Extender on Spermatozoa Motility and Velocity in Fresh and Cooled Stallion Semen

An analysis of Selected Aspects of Sperm Quality in Fresh and Cooled-Storage Stallion Semen

This review summarises the most significant findings related to the issue of the quantitative and qualitative indicators of stallion ejaculates, its processing when producing chilled insemination doses and the possibility of influencing the individual steps of the entire process. Artificial insemination, with cooled-storage semen, is increasingly used in horse breeding because it offers many ad...

Extender and centrifugation effects on the motility patterns of slow-cooled stallion spermatozoa.

Slow-cooled stallion spermatozoa, with and without seminal plasma removed by centrifugation, were diluted in Kenney's extender (KE) containing nonfat dry skim milk with glucose and antibiotics or in KE supplemented by adding a modified high-potassium Tyrode's medium (KMT). Four ejaculates from each of four stallions were collected and divided factorially across these four treatments. Percentage...

Effects of In Vitro Zinc Sulphate Additive to The Semen Extender on Water Buffalo (Bubalusbubalis) Spermatozoa before and after Freezing

Effects of Extender and Storage Time on Motility and Ultrastructure of Cooled-Preserved Boar Spermatozoa

Artificial insemination (AI) using fresh diluted semen is used worldwide in the porcine industry. Viability of spermatozoa in diluted semen depends on several factors, such as the interaction with the type of extender and storage duration. The aim of this study was to evaluate the effects of extenders and storage time on the motility and ultrastructure of cooled-preserved boar spermatozoa. Seme...

Improving the Post-thaw Viability of Cryopreserved Stallion Spermatozoa

The present study was to improve the success for the cryopreservation of stallion spermatozoa, especially as the costs of using low post-thaw motility or sub-optimal fertility deters owners and breeders from using frozen semen. The aim was to develop a freezing extender/process that supports cell survivability throughout the freezing. Eleven stallions were collected and frozen in INRA 96 with t...
