Caracterización morfométrica y clasificación de los espermatozoides de vicuña (Vicugna vicugna) usando el sistema ISAS® CASA-Morph
(Spermova, 2021)
he aim of the study was to determine the morphological and morphometric characteristics of
the vicuña sperm (Vicugna vicugna), looking for possible subpopulations in its structure. Semen
was collected by electroejaculation ...
Perceptions of animal welfare on livestock: evidence from college agronomy students in Costa Rica
(Animals, 2024)
This article focuses on students dedicated to the study of agronomy. To identify
the general perception of students about animal welfare in production systems, four categories were
developed and presented through a survey. ...
Relationship between fertility traits and kinematics in clusters of boar ejaculates
(Biology, 2021)
Swine reproduction efficiency is determined by the fertility potential of the sow
and sperm quality. The objective of this study is to compare boar sperm motility and kinematic
features to evaluate their relationships ...
Effect of an energy supplementation, weaning and oestrous synchronisation on ovarian activity and ovulation in early postpartum primiparous Bos indicus cows raised in the tropics of Costa Rica
(Animal Production Science, 2016)
To evaluate the effect of an energy supplementation, 26 postpartum Bos indicus cows were assigned either
to receive an energy diet supplementation (n = 11, SSD) or no supplementation (n = 15, NSSD). Cows in the SSD ...
Detrimental effects of non-functional spermatozoa on the freezability of functional spermatozoa from boar ejaculate
(PLOS One, 2012)
In the present study, the impact of non-functional spermatozoa on the cryopreservation success of functional boar
spermatozoa was evaluated. Fifteen sperm-rich ejaculate fractions collected from five fertile boars were ...
Morfometría y subpoblaciones de espermatozoides de llama (Lama glama) usando el sistema ISAS® CASA-Morph
(Revistas de Investigación y Veterinaria del Perú (RIVEP), 2021)
El objetivo del estudio fue determinar la existencia de subpoblaciones espermáticas
según la morfometría de los espermatozoides de llama, utilizando un sistema CASA Morph. Se colectó semen de cuatro llamas Q’ara de 4-6 ...
Condiciones óptimas del análisis CASA-Mot del semen de verraco: efecto de la tasa de fotogramas para diferentes cámaras y campos de recuento espermático
(2021)
El objetivo del estudio fue determinar el efecto de la tasa de fotogramas sobre
diferentes profundidades de cámara de recuento espermático en semen de verraco y
analizar la distribución de los espermatozoides en los ...
Kinematic sub-populations in bull spermatozoa: a comparison of classical and bayesian approaches
(Biology 2020, 2020-06-26)
The ejaculate is heterogenous and sperm sub-populations with different kinematic patterns
can be identified in various species. Nevertheless, although these sub-populations are statistically
well defined, the statistical ...
Morphometry and subpopulation structure of Holstein bull spermatozoa: Variations in ejaculates and cryopreservation straws
(2016)
Sperm quality is evaluated for the calculation of sperm dosage in artificial reproductive programs. The most common parameter
used is motility, but morphology has a higher potential as a predictor of genetic quality. ...
Kinematic and morphometric assessment of fresh semen, before, during and after mating period in brahman bulls
(Animals, 2024)
The objective of the present study was to determine the effects that the reproductive season
has on the motility, kinematics, morphology, and sperm morphometry of Brahman bulls evaluated
with a commercial CASA system. ...
