NUMBER OF OVULATIONS PER ESTROUS CYCLE IN ANDINA AND PERU GUINEA PIG (Cavia porcellus) BREEDS
Descripción del Articulo
The aim of the study was to determine the average number of ovulating follicles inthe Andina and Peru guinea pigs breeds in order to know if the difference in litter sizebetween the two breeds is partly due to the number of ovulations. Fifteen animals of 10weeks of age per breed were used. The day o...

NUMBER OF OVULATIONS PER ESTROUS CYCLE IN ANDINA AND PERU GUINEA PIG (Cavia porcellus) BREEDSNÚMERO DE OVULACIONES POR CICLO ESTRUAL EN CUYES (Cavia porcellus) ANDINA Y PERÚ.Araníbar, EduardoEchevarría C., LuisaCuyPerúAndinaovariocuerpo lúteo.guinea pigPeruAndinaovarycorpus luteumThe aim of the study was to determine the average number of ovulating follicles inthe Andina and Peru guinea pigs breeds in order to know if the difference in litter sizebetween the two breeds is partly due to the number of ovulations. Fifteen animals of 10weeks of age per breed were used. The day of ovulation was considered as day 0 of theestrous cycle and was determined through vaginal cytology and absence of the vaginalmembrane. In day 8 of the estrous cycle vaginal cytology was done to verify that the female was in diestrus and then animals were slaughtered to obtain the ovaries. Thesewere fixed with buffered formalin and histological sections of ovaries were stained withhematoxylin eosin. The samples were observed in optical microscope and corpus lutea(CL) were counted. The Andina breed had 3.6 ± 0.9 CL and the Peru breed had 2.8 ± 0.9 CL(p<0.05). The difference in litter size between the two breeds would be partially due to thehigher number of ovulations per estrous cycle in the Andina breed as compared to thePeru breed.El estudio tuvo por objetivo determinar el número promedio de folículos que llegan a ovular en cuyes de las razas Andina y Perú, con el fin de saber si la diferencia en el tamaño de camada entre estas razas se debe, en parte, al número de ovulaciones. Se utilizaron 15 animales de 10 semanas de edad por raza. Se consideró como día 0 del cicloestral el día de la ovulación, el cual se determinó mediante citología vaginal y ausencia de la membrana vaginal. En el día 8 del ciclo estral se realizó citología vaginal para comprobar que los animales estaban en diestro y se sacrificaron para obtener los ovarios. Estos fueron fijados con formol buferado, se hicieron cortes seriados y se colorearon con hematoxilina eosina. Las muestras histológicas se observaron en microscopio ópticopara el conteo de los cuerpos lúteos. En la raza Andina se encontró 3.6 ± 0.9 cuerpos lúteos y en la Perú se encontró 2.8 ± 0.9 cuerpos lúteos (p<0.05). La diferencia en el tamaño de camada entre las dos razas se podría deber, en parte, a que la raza Andina tiene mayor número de ovulaciones por ciclo estral que la raza Perú.Universidad Nacional Mayor de San Marcos, Facultad de Medicina Veterinaria2014-03-31info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://revistasinvestigacion.unmsm.edu.pe/index.php/veterinaria/article/view/846510.15381/rivep.v25i1.8465Revista de Investigaciones Veterinarias del Perú; Vol. 25 Núm. 1 (2014); 29-36Revista de Investigaciones Veterinarias del Perú; Vol. 25 No. 1 (2014); 29-361682-34191609-9117reponame:Revistas - Universidad Nacional Mayor de San Marcosinstname:Universidad Nacional Mayor de San Marcosinstacron:UNMSMspahttps://revistasinvestigacion.unmsm.edu.pe/index.php/veterinaria/article/view/8465/7348Derechos de autor 2014 Eduardo Araníbar, Luisa Echevarría C.https://creativecommons.org/licenses/by-nc-sa/4.0info:eu-repo/semantics/openAccessoai:ojs.csi.unmsm:article/84652020-03-29T12:11:37Z |
