Publicación Acceso abierto Caracterización morfométrica, faneróptica y dimorfismo sexual del pato Muscovy (Cairina moschata doméstica) en municipios de Córdoba (Colombia)(Grupo de Investigación en Producción Animal Tropical (GIPAT), 2023-07-20) Barros González, Jesús Alberto; Vergara Garay, Oscar DavidIntroduction. The Muscovy duck (Cairina moschata domestica) has the potential to contribute as an economic solution aligned with conservation and production objectives for rural families living in conditions where this species usually develops; this is the case of the municipalities of Córdoba - Colombia. Justification. The morphological characterization is one of the first steps to intensify the sustainable use of this species. Objective. The objective of this work was to carry out a morphological characterization and evaluate the sexual dimorphism of a Muscovy duck population in the rural area of three municipalities of the department of Córdoba (Colombia). Methods. This research was carried out in four farms located in San Pelayo, Canalete, and Montería. Data were obtained from 179 birds, 98 females, and 81 males that fit the morphological descriptions of the Muscovy duck. Nine phaneroptic characteristics, 18 morphometric traits and body weight were recorded. Nine zoometric indices were calculated using the quantitative morphological variables. Frequency tables of the qualitative data and descriptive statistics of the quantitative data, 95% confidence intervals and Pearson's correlations (P≤0.05) between body weight and morphometric characteristics were obtained. Sexual dimorphism was described from Student's t-test (P≤0.05), and a linear discriminant analysis between sexes was performed. The results were obtained using InfoStat® version 2020 and IBM® SPSS Statistics software. Results. It was found that the ducks studied were characterized by a diversity of colors in their plumage, with combinations of white, gray, brown, black, and iridescent black; white, yellow, black, and red skin; brown, black, and depigmented bill; black and yellow eyes, and black and red caruncles, the latter more frequently present in males. They were birds with elongated and narrow heads, with greater body length than dorsal height, elongated trunk, raised in front and with high morphostructural harmony. Males presented higher values than females in all morphological measures (P≤0.05), and indices of compactness, massiveness, and condition (P≤0.05), while females presented greater robustness and proportionality (P≤0.05). Both sexes expressed high pelvic indices without significant differences (P>0.05). The measurements with the highest discriminant power were head width, neck length, body length, longitudinal diameter, wing length, and body weight. Conclusions. The results obtained are a contribution to the information on the morphological characteristics of the Cairina moschata domestica duck in Colombia, useful for the conservation of this native genetic resource, its genetic improvement and recognition of its productive aptitudes, as they are a basic reference for future research.Publicación Acceso abierto Enriquecimiento ambiental en ocelotes (Leopardus pardalis linnaeus, 1758) mantenidos en cautiverio en el CAV de CVS de Montería Córdoba(CAV Centro de atención y valorización de Fauna silvestre y C.V.S (Montería- Córdoba), 2023-02-17) Torres Díaz, Elvis Francisco; Yepes Escobar, Juan; Muños Rojas, Alberto ElíasAt the Center for Attention and Valuation of Wild Fauna (CAV) of the Regional Corporation of the Sinú and San Jorge Valleys, wildlife specimens are received by means of seizure, rescue or voluntary surrender, they are medically and biologically valued, providing all the necessary care according to the conditions of the specimen. Within the framework of these protocols is the morphometry process, where body measurements of the animal are taken. On the other hand, the veterinary medical assessment is in charge of evaluating the state of the individual, to later determine if they will go to quarantine or if they can be released immediately. If quarantine is carried out, adequate biological environment, nutritional diet and monitoring are carried out, according to age, size, sex and species. When the animals fail to survive captivity, diseases or accidents, a necropsy is carried out, in order to obtain an accurate verdict of death, organ conditions, sampling, etc. In the rehabilitation stage, one of the problems that is observed in animals that are in captivity is the loss and gradual deterioration of the behaviors that they need to survive in their natural habitats. In carnivorous species such as cats, the behaviors that are most affected are those that are related to illegal trafficking hunting activities. The objective of this internship work was focused on carrying out different types of environmental, behavioral, nutritional and olfactory enrichment in order to help rehabilitate a female leopard pardalis species in order to help her improve her stress and hair loss to thus being able to give it an adequate rehabilitation and proceed to release it in its natural habitat. For this work, different types of enrichment were carried out for this species, and through blood counts and nocturnal cameras it was possible to analyze various behaviors which helped this species of ocelot in the CAV of the CVS for its subsequent rehabilitation.
