Presence of sexual dimorphism between Muscovy ducks (Cairina moschata) in the backyard of three communities in Guatemala

In this study, we investigated the sexual dimorphism between males and females of Muscovy ducks freely bred in three different communities in Guatemala. The analysis was based on 14 important morphological features: wing length, rear limb length, dorsal elevation, head length and head width, longitud...

description In this study, we investigated the sexual dimorphism between males and females of Muscovy ducks freely bred in three different communities in Guatemala. The analysis was based on 14 important morphological features: wing length, rear limb length, dorsal elevation, head length and head width, longitudinal and bicostal diameter, eternal back length, rump height, chest perimeters and perimeter of the metatarsal and body weight. A sample consisting of 137 males and 225 females. Males had a higher mass than females but were less robust and legs. The discriminatory analysis revealed that males could not be grouped together, but Camotan's females are different from the rest. Detailed analysis showed that most of the differential variables (abdominal and chest perimeters) were not related to ethnological traits, so the Camotán group can be considered as a mere prototype (associated with selection and artifcial reproduction), not an ecotype (as if what makes ecotypes adaptive to local conditions, this is not the case). The results of this study could be effective in characterizing and preserving the genetic resources of Muscovy Duck in Guatemala. It is now necessary to study the quality of the carcasses and egg and other variations at the molecular level that will further clarify the similarity with ducks of other origins to register this breed internationally.

El análisis se basó en 14 rasgos morfológicos importantes: longitud del ala, longitud del miembro posterior, alzada dorsal, longitud de la cabeza y ancho de la cabeza, diámetro longitudinal y bicostal, longitud dorsoesternal, altura de grupa, perímetros torácico y abdominal, perímetro del metatarso y peso corporal. Una muestra constituida por 137 machos y 225 hembras. Los machos presentaron una mayor masa que las hembras, pero eran menos robustos y patas. El análisis discriminante reveló que los machos no podían agruparse, pero las hembras de Camotán son distintas del resto. El análisis detallado demostró que la mayoría de las variables diferenciales (perímetros abdominales y del tórax) no estaban relacionadas con rasgos etnológicos, por lo que el grupo Camotán puede considerarse como un mero prototipo (asociado con la selección y reproducción artificial), no un ecotipo (como si lo que hace que los ecotipos sean adaptativos a las condiciones locales, este no es el caso). Los resultados de este estudio podrían ser efectivos en la caracterización y conservación de los recursos genéticos del pato Muscovy en Guatemala. Ahora es necesario estudiar la calidad de la canal y del huevo y otras variaciones a nivel molecular que aclararán aún más la similitud con los patos de otros orígenes para registrar esta raza internacionalmente.La ejecución y redacción del presente estudio no hubiera sido posible sin el cofinanciamiento de la Dirección General de Investigación de la Universidad de San Carlos de Guatemala, programa de recursos naturales y ambiente, partida presupuestal 4.8.24.1.04, 2019.Centro Universitario de Sur-Oriente.
