Background: ATP exogenous (ATPe) has been used successfully in improving motility and fertility for many animal species. However this has not yet been tested on Brycon orbignyamus.
Objective: The objective of this study was to evaluate the use of ATPe for the cryopreservation of sperm from B.
Background: The low molecular weight and high cellular permeability of amides make them suitable for use as penetrative cryoprotectants for sperm cells.
Objective: This study aims to evaluate the effect of dimethylformamide (DMF) and dimethylacetamide (DMA) on sperm cryopreservation of Curimba (Prochilodus lineatus).
Materials And Methods: Semen samples were diluted in media containing cryoprotectants [DMF, DMA and dimethyl sulfoxide (DMSO)].
Background: Automated equipment with customized freezing curves can be used to cryopreserve ram sperm, but none is considered a standard.
Objective: This study compared the post-thawing quality of ram sperm frozen using a conventional freezing curve and two controlled-rate curves.
Materials And Methods: Six ejaculates were collected from four rams (n = 24).
Background: The aim of this study was to analyze the effect of reduced glutathione (GR) and adenosine triphosphate (ATP) in cryopreserved sperm tambaqui, Colossoma macropomum..
Objective: Semen samples were frozen at different concentrations of GR (2, 4, and 6 mM) and ATP (7.
