    Rescate de una bebida ancestral de granos andinos tipo café elaborado por la Asociación Jatari Warmi
    (Universidad Católica de Cuenca., 2024) Santos Peralta , Alex Fabricio; Maldonado Cornejo, Manuel Esteban; 0107180994
    The Agroecological Association Jatari Warmi, located in the parish of Jadán, canton Gualaceo, province of Azuay, is a group of women agro-producers that promote practices to enhance the popular and solidarity economy through agroecological and sustainable food production. This study focused on promoting an ancestral beverage made from grains produced by the Association through its internal processes. To achieve this, post-harvest practices and seed conservation were investigated to determine their applicability in producing coffee-like beverages. In order to add qualitative value to the product for its establishment in the market, an internal product development process was established with the members, and an organoleptic evaluation was conducted with the public, together with a nutritional evaluation of its composition. Finally, its potentialities were consolidated, resulting in the development of a commercial product, "APU BY JATARI WARMI," which can be sold at Agroecological fairs and integrated into the Association's commercial portfolio, thus becoming one of the possible flagship products of the Association and generating higher profit margins. It was concluded that when developing a food product based on a recipe passed through generations, the use of techniques and knowledge specific to the environment is crucial and must be respected in all aspects, avoiding the gentrification of the process and thereby increasing its quality without interfering with the customs of the community, preserving knowledge and fostering fair trade.

    Aislamiento y caractrización molecular de hongos (ecto y endo) micorrizicos asociados al cultivo de maíz (Zea mays L.) en el bosque seco del sur del país
    (Universidad Católica de Cuenca., 2023) Galarza Riera, Christian Andres; Salazar Orellana, Marjorie Jazmín; 0105846596
    This research aimed to evaluate the diversity of fungi in the rhizospheric soil of maize grown under different agricultural practices in the Pindal canton, Loja province, Ecuador. Soil and root samples were collected from two experimental sites under the three agricultural practices: planting, urea application, and burning. The samples were analyzed by molecular techniques to identify the presence of fungi. The results indicated that the rhizospheric soil of the two experimental sites showed a high fungi diversity. A total of seven fungal species were identified in the soil and 28 fungal species in the maize root. Metagenomic analysis of the soil revealed seven bacterial classes, 16 fungal families, and four species of mycorrhizal fungi. The functions of the fungi present in the root and soil were classified into 15 groups. The composition of the fungal community colonizing the rhizospheric soil varied according to agricultural practices. The rhizospheric soil of the dry forest had a higher diversity of fungi than the rhizospheric soil of the experimental sites with agricultural management. Finally, soil chemical and physical properties varied according to agricultural practices. The results demonstrate that the rhizospheric soil of the corn crop is a complex environment with a high diversity of fungi. Agricultural practices can affect the composition of the fungal community, colonizing the rhizospheric soil, which can impact on crop yield and quality. Keywords: microbial community, mycorrhizae, metagenomics, agricultural practices.

    Relación de las caracteristicas corporales, morfometría testicular y la viabilidad de espermatozoides epididimarios en caninos post-orquiectomia
    (Universidad Católica de Cuenca., 2023) Jiménez Jaramillo, Erik Mauricio; Veloz Veloz, Dina Marisela; 1105116949
    Studying the relationship between testicular morphometry, age, weight, and sperm viability in dogs is fundamental to understanding animal reproduction. This study aimed to correlate body characteristics, testicular morphometry, and post- orchiectonomy epididymal sperm viability. The clinical records of the patients were obtained, 26 testicular samples were collected, the samples were transported in sterile containers with 9% NaCl solution, and testicular morphometric data such as length, depth, width, and weight were recorded. Spermatozoa were collected using the retrograde flow technique with Tris+yolk solution. Each sample was evaluated to determine sperm quality, and the parameters assessed were: concentration, individual progressive motility, vitality, plasma membrane, and acrosomal integrity. A correlation test was performed between testicular morphometry and sperm kinetics, finding a moderate correlation between these two variables, with testicular length being one of the most relevant referents. Age and weight were also related to sperm parameters, with age showing a positive relationship with sperm concentration but a negative tendency with the fluorescence test. Weight showed a high relationship with individual progressive motility and hypo-osmotic test. Overall, the results indicate that the body characteristics of dogs can influence their sperm quality, highlighting the importance of understanding the relationship between these characteristics and sperm quality in dogs, which may have implications for animal reproduction and breeding protocols. Keywords: correlation, epididymis, morphometry, analysis, retrograde flow

    Niveles Séricos de Testosterona en Cavia Porcellus Tratados con innosure y su influencia sobre el desarrollo productivo
    (Universidad Católica de Cuenca., 2023) Chicaiza Méndez, Josue Daniel; Valverde Molina, Melky Rolado; Cuenca Condoy, Mercy del Cisne; 1501166019; 0106076615
    This research aimed to evaluate the effect of the variation of serum testosterone levels in guinea pigs (Cavia porcellus) treated with different doses of Innosure and its effect on product development and regulation of social behavior. Eighty-one 21-day-old guinea pigs from the Peru line were used, divided into three treatments: T0 (control), T1 (0.10 ml of Innosure), and T2 (0.20 ml of Innosure), including densities of 6, 9, and 12 animals. The dose of Innosure was applied at 50 and 80 days of the age of the animals. The variables studied were: testosterone levels, productive parameters, and aggressive behavior. The results showed that the productive parameters of the guinea pigs treated with Innosure were not significantly affected (p>0.05); however, the density managed reflected a positive effect on this variable, reaching the highest carcass weight (6 animals) with 706.28 g and a feed conversion ratio of 3. Testosterone levels of the guinea pigs did not decrease significantly with the application of the vaccine, nor did the aggressive behavior. It is concluded that the Innosure vaccine does not effect on productive parameters, does not regulate the social behavior of the species, and does not decrease testosterone levels in guinea pigs. Keywords: Cavia porcellus, Innosure, productive parameters.

    Determinación de la incidencia de piroplasmosis en caninos, mediante la tinción de Wright, en el sector Challuabamba, parroquia Machángara, cantón Cuenca.
    (Universidad Católica de Cuenca., 2015) Mejía Pacho, Miriam J.; Galarza Molina, Leonardo; 0105209563
    La presente investigación, se llevó a cabo como tesis de grado en la carrera de Medicina Veterinaria de la Universidad Católica de Cuenca. Los objetivos planteados para esta investigación fueron: evaluar la incidencia de Piroplasmosis canina mediante la tinción de Wright, diagnosticar en forma correcta los resultados obtenidos del análisis de las muestras y aplicar el procedimiento y tratamiento de acuerdo a procedencia, edad y sexo. El método de campo se basó en la extracción de sangre de la vena cefálica en tubos que contenían anticoagulante, siendo etiquetados y transportados hacia el laboratorio, donde las muestras obtenidas se procesaron. Se realizó un frotis de cada muestra en un portaobjetos, y en cada caso se aplicó tinción de Wright, dejando un tiempo de reposo de 20 minutos; después se procedió a observar a través del microscopio con el lente de inmersión 100x, con el fin de identificar el agente piroplasma. Como resultado final del estudio, se obtuvo 1 solo caso positivo de las 510 muestras; el cual, a partir del análisis estadístico paramétrico y de la representación gráfica de barras y porcentajes, permite concluir que la incidencia de piroplasmosis en caninos, mediante la tinción de Wright, en el sector Challuabamba, Parroquia Machángara del cantón Cuenca, resulta ser no significativa.
