| dc.description | Zeal in animals is the part to lead to their reproduction, these estrous cycles occur in certain periods of time depending on the species and even in which area of the planet it is. The canine female fulfills the main objective of the study of this thesis since the estrous cycle of the same is determined and how many times a year they occur and if the place where it is influences through its photoperiod which will give way to allow copulation of the male and carry out the pregnancy. To understand this natural process such as heat we have to know that it consists of several stages of a hormonal order that meet specific and necessary characteristics to carry the creation of a new being as the final objective. For the development of this document, bibliographic information was collected from scientific journals, books, scientific articles, websites and other theses carried out. Similarly, the object of study also focused on the analysis of the reproductive system of the female canine and the functions that each of its structures fulfill, especially those that regulate the estrous cycle. The reproductive cycle is made up of; proestrus, estrus, right-handed and anestrus, which are the stages in which the canine female shows endocrine and behavioral changes until reaching a state of pregnancy. Studies carried out in both Uruguay and Peru have determined that there are changes in the behavior of heat in the female canine, depending on the place, temperature, photoperiod and time of year, data that to date are not conclusive. | es_ES |

| dc.description.abstract | El celo en los animales es la parte para conllevar a la reproducción de los mismos, estos ciclos estrales se dan en periodos de tiempos determinados dependiendo la especie e incluso en que zona del planeta este. La hembra canina cumple como principal objetivo el estudio de esta tesina ya que se determina el ciclo estral del misma y cuantas veces al año se dan y si el lugar en donde se encuentra influye a través de su fotoperiodo la cual dará paso para permitir la copula del macho y efectuar la preñez. Para entender este proceso natural como lo es el celo tenemos que saber que consta de varias etapas de orden hormonal que cumplen características específicas y necesarias para llevar como objetivo final la creación de un nuevo ser. Para el desarrollo del presente documento se recolecto informaciones bibliográficas de revistas científicas, libros, artículos científicos, sitios web y otras tesis realizadas. De igual manera el objeto de estudio también se centró en el análisis del aparato reproductor de la hembra canina y las funciones que cumplen cada una de sus estructuras, especialmente en aquellas que regulan el ciclo estral. El ciclo reproductivo está formado por; proestro, estro, diestro y anestro que son las etapas en las cuales la hembra canina evidencia cambios endocrinos, conductuales hasta alcanzar un estado de preñez. Estudios realizados tanto en Uruguay como Perú han determinado que existen cambios en el comportamiento del celo en la hembra canina, dependiendo del lugar, temperatura, fotoperiodo y época del año, datos que hasta la actualidad no son concluyentes. | es_ES |
