dc.descriptionAndrological evaluation is currently one of the most used means to evaluate whether the pig selected as a semen breeder does not have any morphology, whether its sperm concentration is of good quality and to be able to continue using the semen as artificial insemination. The objective of the work was to andrologically evaluate the breeding pigs destined for semen production at the López Suarez Parroquia Guare farm. Three breeding pigs of the German Pietrain, Pietrain Plus and Duroc breeds were used. Non-parametric statistics were used for the analysis of this research and the results will be presented in percentages, tables and graphs. The variables evaluated were volume, pH, mass motility, sperm concentration and sperm morphology. The macroscopic variable of semen, appearance and color were similar on days zero, four and seven. The Ph showed variation between days and breeds. Mass motility on days zero and four was very good, unlike on day seven it was good. In sperm morphology there were no numerical differences on day zero, while on days four and seven there were differences between the breeds under study. In the Analysis of the semen quality of the Pietrain Plus, German Pietrain and Duroc breeders, they presented numerical differences between days zero, four and seven as shown in tables four, five and six. The Pietrain plus and Duroc breeds obtained a greater ejaculate volume (300ml) and the German Pietrain breed had a lower ejaculate volume (250ml).es_ES

dc.description.abstractLa evaluación andrológica en la actualidad es uno de los medios más utilizados para poder evaluar si el cerdo seleccionado como reproductor de semen no tiene ninguna morfología, si su concentración espermática está en buena calidad y poder seguir utilizando el semen como inseminación artificial. El objetivo del trabajo fue evaluar andrológicamente a los cerdos reproductores destinados a la producción de semen en la granja López Suarez Parroquia Guare. Se utilizaron tres cerdos reproductores de las razas Pietrain Alemán, Pietrain Plus y Duroc. Para el análisis de esta investigación se utilizó estadística no paramétrica y los resultados se presentarán en porcentajes, tablas y gráficos. Las variables evaluadas fueron volumen, pH, motibilidad masa, concentración espermática y morfología espermática. La variable macroscópica del semen, aspecto y color fueron similares en los días cero, cuatro y siete. El Ph presento variación entre los días y razas. La motilidad masal en los días cero y cuatro fue muy buena a diferencia del dia siete fue buena. En la morfología espermática no hubo diferencias numéricas en le dia cero, mientras que en los cuatro y siete presentaron diferencias entre las razas en estudio. En el Análisis de la calidad seminal de los reproductores Pietrain Plus, Pietrain alemán y Duroc presentaron diferencias numéricas entre los días cero, cuatro y siete como se muestra en las tablas cuatro, cinco y seis. las razas Pietrain plus y Duroc obtuvieron mayor volumen de eyaculado (300ml) y la raza Pietrain alemán fue menor el volumen de eyaculado (250ml).es_ES
