- ÍtemAcceso AbiertoAdaptabilidad del hibrido de maíz P4021 con tres densidades de siembra en el cantón Oña, provincia del Azuay(Universidad Católica de Cuenca., 2024) Ullauri Sandoval, Marco Esteban; Vázquez Vázquez, Jacinto Enrique; 010455117Corn stands out as the sole cereal suitable for human and animal consumption. Climate change-related alterations suggest the search for alternative animal feed. This research aimed to assess the effects of planting density on the agronomic performance of the P4021 corn hybrid in the Oña canton, Azuay province. A Randomized Complete Block Design (RCBD) was used, consisting of four treatments and four replicates, with a total of 16 experimental units of 12 m2 each across a 448 m2 area. Four planting densities —20, 40, 60, and 80 cm between plants, all at 60 cm between furrows— were tested, with two seeds dibbled per hole. The results revealed that planting density significantly impacts the agronomic performance of P4021 corn. Although no significant differences were observed on variables like height and leaf count, there were statistical differences in the variable weight per treatment (kg), highlighting the T1 treatment (40 cm between plants) with a mean of 27.6 kg. The cost analysis considers the T1 treatment as the optimal choice for planting this hybrid, compared to the control treatment (T4). In conclusion, planting density affects Hybrid P4021 cultivation, with 40 cm between plants yielding the best results in terms of profitability in the cost of production analysis, resulting in a 170% increase, making the T1 treatment ideal for corn silage.

- ÍtemAcceso AbiertoAislamiento 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; 0105846596This 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.
- ÍtemAcceso AbiertoAnálisis bibliográfico sobre el uso de la saccharina rustica en la alimentación animal(Universidad Católica de Cuenca., 2021) Castillo Crespo, Diana Marisol; Iñiguez Heredia, Franklin Alfredo; 0302715511The objective of the research carried out is to analyze the rustic Saccharina as food in the different species of animals in production, to supply the nutritional deficit or to couple it in new diets. Saccharina is a product obtained from the solid fermentation process of sugar cane, devoid of buds and leaves, supplemented with urea and minerals; where, it potentiates its nutritional composition. In monogastric and polygastric animals, energy competition is emphasized compared to dry grains, as is the case with the supply of 70% of Saccharina in rams, where there was a difference of only 5% of energy in corn and wheat. The possibility of replacing forages up to 60% in guinea pigs is also highlighted. Besides that it is a product that can be used in birds, as in the case of geese, which are not affected if it is included between 30% to 60%. In the same way, in ruminants, a better behavior of Saccharina and the production in dual-purpose and dairy cattle are emphasized. Among the restrictions that act against the quality of the product is the particle size, the thickness of the mattress and the fermentation time, which must be 0.5 cm, 5 cm and 48-36 hours respectively. Saccharina rustica boasts high levels of protein, energy and minerals; using it for animal consumption, in addition to replacing forages and concentrates in certain percentages; Likewise, it has been used to mix with feed and commercial balanced, giving good results at low costs.

- ÍtemAcceso AbiertoAplicación de dos técnicas de estimulación hormonal para extracción espermática en atelopus nanay, atelopus bomolochos y ctenophryne aequatorialis(Universidad Católica de Cuenca., 2023) Coronel Sarmiento, Helen Nicole; Zhumi Cajamarca, Jefferson Mauricio; Argudo Garzón, Daniel Ernesto; 0350191862; 0150765733Ecuador is recognized for its great diversity of amphibian species currently threatened worldwide. In this context, this study evaluated the feasibility of two hormonal techniques (GnRH and hCG) to improve sperm performance in three species: Atelopus nanay, Atelopus bomolochos, and Ctenophryne aequatorialis, in the Azuay province. The application of hormones is effective in stimulating sperm release in amphibians. Previous studies have obtained favorable results using GnRH and hCG in different species. The conservation of amphibians under human care has become crucial due to the decline of in situ populations. Currently, there is an amphibian conservation center of the Amaru Foundation in Cuenca, Ecuador. Sperm collection was conducted in three species of amphibians with hormone doses of 4 μg/g and five μg/g, respectively. The results show significant differences in sperm parameters between species and hormone treatments applied. It was demonstrated that the application of GnRH and hCG generated a high motility index between 3.5- and 5.5-hours post-application and a high sperm concentration between 2.5- and 3.5-hours post-application of the treatments in Atelopus nanay and Atelopus bomolochos. No relevant results were obtained for the species Ctenophryne aequatorialis.

- ÍtemAcceso AbiertoBiocicatrización del extracto de Jungia Rugosa less sobre heridas quirúrgicas en conejos(Universidad Católica de Cuenca., 2023) Proaño Barreiro, Marco Joaquin; Castillo Hidalgo, Edy Paúl; 0104937016ABSTRACT Jungia rugosa, known as Human Meat, is a medicinal plant native to the Andes. It has been used ancestrally for the healing of wounds; its anti-inflammatory, antimicrobial, and healing properties are related to its content of flavonoids and polyphenolic compounds. This study evaluated the healing effect of Jungia rugosa extract on postsurgical wounds using nine rabbits as biological models. Two semi-solid creams at 5% and 10% were prepared with its extract, which were compared with the traditional use of the plant. The non-invasive surgical procedure consisted of the creation of three 2cm surgical wounds in different anatomical areas (loin, right and left scapula). The rabbits were randomly assigned to three treatment groups: T1 (5%), T2 (10%), and T0 (Control), achieving complete wound healing eight days after the start of healing. Despite not observing statistically significant differences in the healing process between the traditional use of the plant and the cream, the healing obtained by the use of Jungia rugosa proved to equal and/or exceed the results obtained with other commercial products. It was determined that treatment T1 (5%) offers higher quality healing, indicating that the application of creams could be an effective alternative to take advantage of the medicinal properties of this plant. This choice is based on the limitation of being unable to preserve or store the macerates produced in the field, which could promote greater use of the plant in future research. Keywords Jungia Rugosa, Flavonoids, Polyphenolics, Biohealing, Oryctolagus cuniculus

- ÍtemAcceso AbiertoCambios clínicos y conductuales post operatorios de un paciente con SRB: estudio de caso(Universidad Católica de Cuenca., 2024) Idrovo Calle, Andrea Nohelia; Castillo Hidalgo, Edy Paul; 0605694470The objective of the present investigation was to evaluate the clinical signs and behavioral modifications of a 2-year-old American Bully canine patient, affected by Brachycephalic Respiratory Syndrome (BRS), during the postoperative period. Prior to the scheduled surgery, the medical history (HC) was performed, which allowed us to document the patient's post-surgical changes. In addition, the response of the respiratory, cardiovascular, metabolic, skeletal muscle and neurosensory systems to the stress imposed by exercise was evaluated through the 6-minute effort test, and animal welfare evaluations were also carried out through freedom of sleep. and comfort, feeding, and interaction with other dogs over a 5-day period. The surgical procedure consisted of two phases: the first involved the correction of the elongated soft palate through staphylectomy, while the second phase included rhinoplasty and correction of nares stenosis. Additionally, the same tests were carried out to collect post-surgery data. After the completion of the surgery, the patient remained under observation during which time an episode of respiratory dyspnea occurred, a phenomenon considered “common” in these patients attributed to the presentation of postsurgical laryngeal edema. Subsequently, saturation remained between 87% and 96%. % SPO2, with an average of 91% SPO2, respiratory sounds decreased significantly, and the feeding process, previously affected by SBR, showed improvement on the first postoperative day, an increase in the quality of sleep and rest of the patient was also observed.
- ÍtemAcceso AbiertoCaracterización de semen de zángano y efecto de la jalea real en la crio preservación de los espermatozoides(Universidad Católica de Cuenca., 2023) Enríquez Duma, Carlos Fernando; Lalvay Quezada, Jonathan Santiago; Argudo Garzón, Daniel Ernesto; 0105623466; 0105936900Pollinator populations, particularly bees, have significantly declined due to environmental changes and the indiscriminate use of pesticides, affecting the number of hives worldwide. This has decreased their pollination service, triggering a low agricultural yield that jeopardizes food security. Cryopreservation offers a potential solution for species preservation. Therefore, this study aims to evaluate the effect of adding royal jelly to the cryopreservation of drone spermatozoa, for which seminal samples were extracted from 396 drones. Initially, the fresh semen was characterized as a starting point; then two treatments were prepared; T1 DMSO as a cryoprotectant along with a TCG-based diluent (tris, citric acid, glucose) containing egg yolk supplemented with 1% jelly, and T2 without jelly supplementation (control). These samples were cryopreserved to evaluate seminal quality after thawing. The results obtained indicated a 38.4% sperm collection efficiency and an average ejaculate volume of 0.8 µL, with a sperm concentration of 2.8 ± 0.43 X 106. In addition, significance for the morphology variable was expressed, while the motility, membrane integrity, and viability variables showed no significant differences. The data were subjected to the Student’s T-test. In conclusion, the post-cryopreservation data of drone semen revealed limited benefits; however, experimentation with the inclusion of percentages other than those used in this study is necessary to optimize the results
- ÍtemAcceso AbiertoCaracterización sanitaria de bovinos previo al faenamiento en el camal del cantón Cuenca(Universidad Católica de Cuenca., 2024) Lopez Lapo, Cristhian Alexander; Iñiguez Heredia, Franklin; 1105227159In the Municipal Slaughterhouse of Cuenca, Azuay province, the cattle's Body Condition (BC) before slaughter was evaluated. For this, specific evaluation parameters were determined, such as age, physiological constants (heart rate, respiratory rate, temperature), sex, breed, and origin, to analyze their influence on BC. Five hundred animals were sampled to analyze the variables, representing a single experimental unit. The results showed that most heads of cattle came from Molleturo with 17%, followed by Cordero and Valle with 13% and 12%, respectively. Regarding the breed variable, 90% of the sample were crossbreeds. The mean age was 2.55 with a median of 2.50, and a correlation of 0.10 was determined between the BC variable and age, showing a value (P = 0.500) between both variables. Regarding sex, 57% were males and 43% were females, with males exhibiting a better body condition of 3.10 compared to females with 2.96, reflecting a p-value of (p = 0.0001). According to the evaluation of physiological constants, all fell within the normal range, and there was a correlation of 0.45 between the variables heart rate (HR) and respiratory rate (RR), indicating that the animals are healthy and fit for the slaughter process. Keywords: Cattle, body condition, slaughter, health.
