The Effect of Season on Semen Characteristics and Freezability in Bos indicus and Bos taurus Bulls in the Southeastern Region of Brazil
(Wiley-Blackwell Publishing, Inc, 2009-08-01)
The objectives of this study were to evaluate the effects of season in southeast of Brazil comparing genotypes on semen characteristics, freezability and peripheral plasma concentrations of testosterone. Ejaculates of five ...
Proteomic profile of sex-sorted bull sperm evaluated by SWATH-MS analysis
(2018-11-01)
The identification of distinct proteins present on the membrane of spermatozoa with X and Y chromosomes allows the development of immuno-sexing techniques. The aim of this study, therefore, was to use mass spectrometry to ...
Genetic parameters for scrotal circumference, breeding soundness examination and sperm defects in young Nellore bulls
(2013-10-01)
A total of 51,161 records of scrotal circumference measurements at 18 mo of age (SCI 8) and 17,648 records of sperm defects and breeding soundness of Nellore bulls (mean age of 22.5 mo), raised under extensive conditions, ...
Flow cytometry sex sorting affects bull sperm longevity and compromises their capacity to bind to oviductal cells
(Elsevier B.V., 2018-01-01)
This study assessed the effect of flow cytometry sexing on sperm longevity and the capacity of sperm to bind to oviductal cells. Each ejaculate from four bulls was divided into two fractions: the first was immediately ...

Effect of refrigeration systems upon frozen bull sperm viability assessed by computer-assisted sperm analysis and fluorescent probes
(Universidade Estadual de Londrina (UEL), 2012-01-01)
Sperm cryopreservation success depends upon the maintenance of spermatozoa fertility potential. Sperm cells must preserve both integrity and functionality of several cell structures. The stabilization phase must allow the ...
