Spirulina platensis extract addition to semen extender enhances cryotolerance and fertilizing potentials of buffalo bull spermatozoa

Abstract: The objective of this study was to investigate the effect of Spirulina platensis extract (SPE) addition to the freezing extender on freezability, lipid peroxidation, ultrastructure alterations and fertilizing potentials of frozen-thawed buffalo bull spermatozoa. Semen samples were collected with artificial vagina from five adult fertile bulls and diluted with Tris-base extender containing SPE (1, 5, 10 and 20 μg/mL) or without SPE (control). Diluted semen was cooled to 4 °C throughout one hour and frozen in 0.… Show more

“…Frozen-thawed samples from each group (repeated in triplicated) were placed on glass slides covered with a cover. After the percentage record of linear motile spermatozoa at 200× magnification under a phase contrast microscope in three different microscopic fields for each sample, the final motility ratio of frozen-thawed sperm motility in each group was calculated based on the mean of three successive estimations ( 27 , 55 , 57 ).…”

“…Por otro lado, la cianobacteria espirulina (Arthrospira spp), ha sido utilizada como suplemento en la alimentación de cerdos [77] y en la conservación de células espermáticas de bovino [78], búfalo [79] y carnero [30]; esta alga es rica en vitaminas (A, D, C, E, B12, B1, B2) [77,79], minerales (hierro, calcio, sodio, potasio, magnesio, fosforo y selenio) [77], ácidos grasos poliinsaturados (ácido gamma-linoleico, ácido alfa linoleico) [77], clorofila [79], espirulanos [30], C-Ficocianina [30] y aloficocianina [30].…”

“…Otros autores en 2021 [79] demostraron que una concentración de 10 g mL-1 de extracto de espirulina (Arthrospira platensis) en el medio base Tris, almacenado a -196°C por 24 horas, aumenta la tasa de concepción de becerros, mejora la movilidad después de la descongelación e incrementa concentración de SOD y GSH; así mismo, disminuye la lipoperoxidación y el daño al acrosoma del espermatozoide de búfalo.…”
