Article Synopsis
  • The study investigates the efficacy of processed egg yolk, specifically through ultracentrifugation and sonication, as a cryoprotectant in the freezing of swine semen.
  • Twenty-seven semen samples were tested using two methods: high-speed centrifugation and sonication, with a control group using regular egg yolk lactose.
  • Results showed that samples processed with centrifugation displayed improved motility and better preservation of cell structure compared to those treated only with sonication.

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.
