Valoración microscópica de la calidad del semen de cuy.

Abstract

This work had the objective of compiling information concerning the microscopic evaluation of guinea pig (Cavia porcellus) semen. An extensive search of scientific publications was carried out in different educational platforms such as Scielo, Spermova, Lantindex, Austin Journal of Veterinary Science & Animal Husbandry. etc, where it was found that the study variables commonly used in seminal evaluation are: sperm concentration (millions/ml), individual motility (%), mass motility (%), vitality (%), normal morphology (%) and sperm morphometry (μm). For each study variable, results from different investigations were analyzed and averaged; the information obtained came from publications no older than five years and for the analysis and presentation of the results, programs such as Microsoft Word and Excel were used. Sperm concentration presented an average value of 105.15 ± 21.64 X 106; individual motility with 62.06 ± 2.88%, which is considered a good quality semen according to the literature; mass motility with 65.16 ± 3.84%, presented an apparent but moderate mass motility; sperm vitality with 77.17 ± 2.95%, a value qualified as optimal; normal sperm morphology with 93.10±10% and the remaining 7.90% corresponds to spermatozoa with abnormal morphology; In the sperm morphometry variable we have the cephalic length with 8.32 ± 0.28 μm; cephalic width with 7.38 ± 0.28 μm and flagellum length 89.69 ± 2.75 μm, concluding the microscopic evaluation is a study that include different variables, these variables were affected by factors such as race, age, semen extraction method, stress and feeding. Therefore, it is recommended to consider the importance of the above-mentioned factors when carrying out a seminal evaluation study.
