Improving the Efficiency of the Preliminary Electroejaculation Technique Developed for Semen Collection from the Agouti (Dasyprocta leporina)

Journal of Zoo and Wildlife Medicine, 2010
This study tested various combinations of ketamine and xylazine with the objective to improve on the efficiency of the preliminary electroejaculation technique developed for semen collection from the agouti (Dasyprocta leporina). There were two experiments, which were each replicated.

A preliminary technique for electro-ejaculation of agouti (Dasyprocta leporina)

Animal Reproduction Science, 2008
This study focused on the effectiveness of electro-ejaculation of the agouti (Dasyprocta leporina) and analysis of the collected semen. Sexually mature male agouti were anesthetized with ketamine and electro-ejaculated. The means of ejaculation time was 5.48+/-0.31min, ejaculation voltage was 9.33+/-0.69V, ejaculation voltage range was 6-12V, amps was ...

Abdominal aortic branches of red‐rumped agouti (Dasyprocta leporina Linnaeus, 1758)

Anatomia, Histologia, Embryologia, 2023
AbstractUnderstanding the cardiovascular system is fundamental in diagnosing pathologies and interpreting exams, such as contrast radiographs. In this context, the present study describes the collateral abdominal aorta artery branches of red‐rumped agouti. Ten red‐rumped agoutis, six males and four females, were assessed.

Vertebromedullary Topography of the Red‐Rumped Agouti (Dasyprocta leporina Linnaeus, 1758)

The Anatomical Record, 2019
ABSTRACTThe agouti is a wild rodent located almost throughout the Brazilian territory, with great scientific importance and high reproductive potential when farmed. In the clinical routine, clinical and surgical procedures are performed on the nervous system of these animals, such as epidural anesthesia and cerebrospinal fluid (CSF) collection; however,

Post-implantation development of red-rumped agouti (Dasyprocta leporina Linnaeus, 1758)

Animal Reproduction Science, 2017
Fourteen pregnant agouti (Dasyprocta leporina Linnaeus, 1758) females at gestational ages of 30-100days and two at gestational ages of 55-100days, were studied, including 24 embryos/fetuses and two neonates (single offspring from two females). Females were euthanized and embryos/fetuses were examined, measured, and photographed.

Perimortality in a Captive Reared Agouti (Dasyprocta leporina).

Wildlife Biology in Practice, 2015
Perinatal mortality has been reported in cattle, swine, goats, sheep and rabbits; however, there have been no documented reports on this phenomenon in agouti (Dasyprocta leporina). The agouti is a Neotropical polytocous rodent, hunted for its meat. This study reports on an incident of perinatal mortalities in a captive reared agouti from the wildlife ...

Spermatozoal morphologies and fructose and citric acid concentrations in agouti (Dasyprocta leporina) semen

Animal Reproduction Science, 2008
This study was conducted to identify the levels of fructose and citric acid, and sperm morphologies in agouti (Dasyprocta leporina) semen. These parameters may be important in identifying highly fertile semen from the agouti. The objectives were: (1) to investigate spermatozoal abnormalities in agouti semen and (2) to determine the concentrations of ...

Comparison among different cryoprotectants for cryopreservation of epididymal sperm from agouti (Dasyprocta leporina)

Cryobiology, 2015
We verify the effects of different cryoprotectants on the cryopreservation of agouti (Dasyprocta leporina) epididymal sperm. We used 16 pairs of testes-epididymis complexes of sexually mature animals. We immediately evaluated epididymal sperm obtained by retrograde flushing for concentration, motility, vigor, viability, osmotic response, and morphology.

Quinolizidine Alkaloids in Ormosia arborea Seeds Inhibit Predation But Not Hoarding by Agoutis (Dasyprocta leporina)

Journal of Chemical Ecology, 2003
Quinolizidine alkaloids (QAs) are secondary compounds found in seeds of many species of plants, possibly protecting them against pathogens and seed predators. QAs were isolated from Ormosia arborea seeds and bioassayed against red-rumped agoutis (Dasyprocta leporina, Rodentia: Caviomorpha) to verify if they inhibit seed predation and food hoarding ...

The Gross and Micro Anatomy of the Accessory Sex Glands of the Male Agouti (Dasyprocta leporina)

Anatomia, Histologia, Embryologia, 2009
SummaryThis study was a follow up to the study on the gross anatomy of the male agouti (Dasyprocta leporina) reproductive system. The seminal vesicles of the agouti are lobulated structures. The mean diameter of the large lumen is 883.6 ± 76.83 μm. The mucosa (24.1 ± 0.92 μm), which is lined by pseudo‐stratified columnar epithelium is thrown into folds,
