- ÍtemAcceso AbiertoAlteraciones del comportamiento en caninos frente al confinamiento por covid-19.(Universidad Católica de Cuenca., 2021) Luna Rojas, Mirely Cecibel; Rubio Arias, Pablo Geovanni; 0604071902Canine behavior disorders are very common worldwide; however, in Ecuador it is still an undervalued issue by owners and veterinarians. The objective of this research was to determine the main behavioral alterations in canines due to the confinement effect in the Covid 19 pandemic. In which it includes environmental, physical and socio-behavioral characteristics; in addition to clinical manifestations, this through frequency ranges from 1 (lowest) - 5 (highest). 200 surveys were conducted with owners who entered the Pet Master, Guaf and Famaves veterinary clinics in the cities of Cuenca and Riobamba respectively. Among the results obtained, there is a greater correlation in tail-chasing behaviors, constant head movements, increased urination and destruction in the environment. Within these signs, it can be foreseen that it is an anxiety disorder, given that it is a pathological state that modifies the balance between the environment, man and objects, making them irritating; in turn, this state leads to easily develop aggressiveness in the pet. Among the treatments used by various researchers, the use of behavior modification programs and the use of drugs from the benzodiazepine group have been chosen, since the results of these have been promising. Keywords: Dogs, behavior, disorders, owners.
- 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.

The oil was extracted from the guácima seed extracted from the dried ripe fruit, dried 3 days, and crushed, whit the help of Soxhlet equipment we separated the essential oil from the solid part, From 30 g of the sample we obtained 0.5 ml, its yield was 2.26 ml, which were placed in blank sensitivity discs, in different concentrations, (T1) guácima extract at 5%, (T2) guácima extract at 25%, (T3) guácima extract at 50% (T4) guácima extract at 100%, (T5) 100% guácima seed essential oil, was prepared by dilutions from the main extract, for the elaboration of the antibiogram, before this, Salmonella typhi ATCC 14028 ® was cultivated on SS agar, the it was sown on Mueller Hinton agar, the antibiogram process; based on the studies conducted, we were able to determine that the average oil obtained was 0.83 ml in 6 extractions, however, Salmonella typhi ATCC 14028 ® did not show sensitivity to the treatments. Keywords: Oil, Extract, Guácima, Salmonella, Typhi.
- ÍtemAcceso AbiertoAnálisis retrospectivo de los diferentes tipos de anemias en caninos (canis lupus familiaris) en la clínica veterinaria austrovet en el periodo 2022(Universidad Católica de Cuenca., 2024) Morocho Nugra, Dario Omar; Aguilar Caivinagua, Andrés Santiago; 0106310865The objective of this retrospective analysis was to identify and classify the different types of anemias using the erythrocyte index (normocytic normochromic, microcytic hypochromic, macrocytic hypochromic, and macrocytic normochromic), marrow production, hemolytic and hemorrhagic anemias, in addition to determining their degree of severity. Consequently, 520 clinical records (hemogram) were analyzed from the Austrovet Veterinary Clinic in 2022. The ratio and frequency statistical method was used to interpret the results. An association between the independent variables (breed, age, and sex) and the dependent variables (types of anemia) was analyzed using the Chi-square statistical method, whose results determined that 202 cases (38.8%) presented anemia; males presented the highest number of cases with 62.9%, while females only represented 37.1% of the total anemias. In terms of marrow production, it was established that non-regenerative anemias had the highest prevalence, with 63.4% of the cases, unlike 36.6% of regenerative ones. Non-regenerative normocytic normochromic anemias were the most prevalent with 50.5%, while only 22.8% were regenerative, followed by non-regenerative hypochromic microcytic anemias with 10.9% of cases, while hypochromic macrocytic and normochromic macrocytic anemias occur with less than 5% of cases respectively. Most of these cases were mild anemia at 43.1%, moderate at 9.20%, severe at 14.40% and very severe at 13.4%.
- 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 AbiertoCambios en la composición microbiana de quesos semimaduros en función del cuajo utilizado(Universidad Católica de Cuenca., 2024) Yanza Contreras, Luis Eduardo; Iñiguez Heredia , Franklin Alfredo; 0104904644The use of rennet in cheese making is a practice in constant evolution, being animal rennet a millenary technique of great cultural and historical value despite the hygienic risks that this entails. This quasi-experimental observational study focused on investigating the details of the process of making semi-mature cheeses according to the rennet used and determining its effect on the microbial composition in the ripening of cheeses for four weeks. It was conducted in the laboratories of the Academic Department of Agricultural Sciences Faculty of the Catholic University of Cuenca. The research compared three treatments with the same milk using different types of rennet (lactating goat, microbial, and synthetic). Ten cheeses were made per treatment, with each cheese representing one experimental unit; their organoleptic characteristics and microbial load were analyzed to determine significant treatment differences. In terms of organoleptic properties, no differences were found between treatments; however, there were differences in the microbial load between treatments. On the one hand, it was observed that there are fewer enterobacteria in the goat cheese —which should be further studied in future research— and a higher concentration of Lactobacillus in the cheeses made with animal and microbial rennet compared to synthetic rennet. This suggests that these rennets are more effective in providing probiotics beneficial to intestinal health, which could have significant implications for the nutritional quality of cheeses.
- 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 morfométrica del semen colectado por masaje abdominal en líneas de gallos criollos(Universidad Católica de Cuenca., 2021) Pillco Minchala, Daniela Estefanía; Maldonado Cornejo, Manuel Esteban; 0107157034The semen quality of creole roosters, collected by abdominal massage, was evaluated using 9 roosters of homogeneous weight and age belonging to three biotypes: Cubans, Barbons, and Guáricos. These had a training period of four weeks, which facilitated semen extraction. Semen collection was performed for 3 weeks, where five samples were extracted from each bird, these being the replicates. Each pool of genetic material was evaluated, regarding the variables color, mass, and individual progressive motility statistical differences were observed (P<0.05) in favor of the Cuban biotype with a qualitative value of 5 that corresponds to a milky white consistency and an observable motility of dense waves, fast and constant movements. For sperm volume and sperm concentration of the creole roosters, the analysis of variance did not show any significant differences (P>0.05). Vitality and viability were quantified by the Eosin Nigrosin method and the HOST method, where sperm vitality was similar (P>0.05) in the three biotypes, unlike viability (P<0.05), where Cuban roosters presented higher values with a 75% chance of fertilization. The variables were correlated, where it was estimated that sperm volume and sperm concentration increase simultaneously (P<0.05). It was concluded that the biotype with the best seminal quality is the Cuban, presenting better results in color, motility, and viability improving these values over time, this information is relevant for the conservation and genetic improvement of poultry. Keywords: Seminal quality, abdominal massage, cubans, barbons, guaricos.
- 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.
