    Guayabo (Psidium guajava L) como regulador de la flora microbiana cecal en pollos broilers.
    (Universidad Católica de Cuenca., 2021) Pachar Tuza, Rene Eduardo; Cuenca Condoy, Mercy del Cisne; 0106570351
    The study determined the effect of Psidium guajava L, as a prebiotic in the feeding of Broiler chickens, using 400 one-day old birds, weighing approximately 45g, assigned to a Complete Randomized Design (CRD), in four treatments, T0 (Control), T1 (0.25% Psidium guajava/ton of feed), T2 (0.50% Psidium guajava/ton of feed) and T3 (0.75% Psidium guajava/ton of feed), including four replicates for each treatment and 25 broiler chicken for each replicate. Zootechnical management was similar in all experimental units, with respect to bird density/m2, environmental variables, sanitary calendar, and nutritional program according to their physiological stage. The variables studied were production parameters (total live weight, weight gain, feed consumption, feed conversion, carcass weight and mortality percentage), and the presence or absence of Salmonella spp at the cecal level. The results related to the production variables did not show significant statistical differences between treatments (p<0.05); however, a numerical difference was recorded, with the best cumulative feed conversion achieved by treatment T1 with 1.27; while the highest carcass weight and the lowest mortality percentage was achieved by treatment T3, with 3164.30g of weight and 2.5% mortality. Regarding the microbial population of Salmonella spp., no positive effect was observed. lt is concluded that the additions of crushed guava leaves do not exert beneficial activity on the productive parameters of the birds nor on the control of Salmonella spp. at the cecal level. KEYWORDS: Broiler Chickens, Salmonella Spp., Productive Parameters, Psidium guajava L.

    Evaluación de la calidad espermática en conejos sometidos a flushing lumínico.
    (Universidad Católica de Cuenca., 2021) Eras Quizhpe, Marcia Alexandra; Argudo Garzón , Daniel Ernesto; 0105147821
    The lighting system is a stimulant for reproduction in some species (horses) and an inhibitor for others (sheep); For this reason, the objective of this study was to determine the effect of light flushing in New Zealand rabbits to evaluate their sperm quality. We proceeded with a sample of 12 rabbits divided into two groups: the experimental group (light flushing) that used 16 hours of lighting (12 hours natural and 4 hours artificial) and the control group that used only natural light (12 hours). A total of forty ejaculates obtained by the method of collection with the artificial vagina and using rabbits as a mannequin were used for their proper collection. A significantly higher average volume was determined in the experimental group (1.02 ± 0.29 vs 0.76 ± 0.26 mL); as well as motility (83.00 ± 16.89 vs 44.75 ± 28.49%). We also found that in the experimental group there was less presence of gel, this difference being statistically significant (10 vs 55%); the amount of abnormalities did show improvement in the number of sperm in the experimental treatment (9.24 ± 7.02 vs 13.75 ± 4.37%). No significant differences were found in sperm concentration; in the percentage of vitality and functionality of the sperm membrane evaluated through the HOS Test. The seminal characteristics had a positive and significant correlation, in terms of volume, motility, with the increase in illumination time, and negative and significant correlations with the presence of gel and abnormalities. In conclusion, subjecting rabbits to four hours of artificial light improves the seminal characteristics of rabbits. Keywords: light flushing, sperm quality, rabbits, semen collection.

    Efecto de allium sativum, zingiber officinale y piper carpunya, como prebióticos en pollos broiler.
    (Universidad Católica de Cuenca., 2021) Moina Remache, Dannes Fernando; Cuenca Condoy, Mercy del Cisne; 0106401144
    The study evaluated the effect of Allium sativum, Zingiber officinale and Piper carpunya, as prebiotics in Broiler chickens, for them 1000 chickens of the Broiler line, one day old, with an average weight of 45 g were used; the birds were distributed under a complete random design, in five treatments, T0 (Control), T1 (0.5% Garlic), T2 (0.5% Ginger), T3 (0.5% Guaviduca) and T4 (0 , 5% between Garlic + Ginger + Guaviduca), including 4 repetitions for each treatment and 50 chickens for each repetition. The zootechnical management of the birds was similar in all the experimental units, especially in what corresponds to density of birds / m2, environmental variables, sanitary calendar and nutritional program in terms of quantity of food supplied. The variables evaluated were productive parameters (total live weight, weight gain, feed consumption, feed conversion, carcass weight and percentage of mortality), hematological profile (erythrocyte count, hematocrit, hemoglobin, leukocytes, heterophiles, lymphocytes, eosinophils, basophils and monocytes) and serum immunoglobulin levels (IgG, IgM, IgA / mg / dl). The results showed that the combination of 0.5% of Garlic, Ginger and Guaviduca improves the production parameters of the birds, regarding weight increase and feed conversion; However, regarding the weight of the organs of the immune system, hematological profile and immunoglobulins, it was evidenced that the addition of natural prebiotic products in the diet of broilers has a positive impact on these variables. It is concluded that the use of natural products as prebiotics improves the productive parameters and the immune system of the birds, being able to be a substitute alternative to growth-promoting antibiotics. Keywords: Garlic, Ginger, Guaviduca, Broilers, performance, immune system.

    Diseño e implementación de un prototipo de incubadora neonatal para perros.
    (Universidad Católica de Cuenca., 2021) Nugra Alvarracin, Ramiro Fernando; Rubio Arias, Pablo Geovanny; 0105139430
    In this work shows the design and construction of a medical device capable of simulating an environment conducive to canine neonates, contributing a suitable monitoring of physiological parameters in such a way that the operator easily manipulates the device, being of great help for veterinary centers. To reduce the canine neonatal mortality rate. The neonatal incubator encompasses the structural construction and a manual control system, it is proposed to use a software and hardware system Opensource (Open Source) and DIY Do It Yourself (Do it yourself), which were highly accessible. The controls are automated for the four programmed states depending on the humidifier, fan and heater, being easy to manipulate with the buttons to change ranges, all this will depend on the week the puppy enters the incubator. The programming given for each state or week that the incubator is automated, both the heater, humidifier, fan, as well as the oxygen flow, are independently programmed to function according to each of them, for example, if the temperature rises more than Allowable range the fan turns on and is responsible for entering air into the passenger compartment, as well as having high concentrations of CO2, oxygen will enter. Keywords: Incubator, Neonate, Temperature, Humidity, Oxygen.

    Alteraciones del comportamiento en caninos frente al confinamiento por covid-19.
    (Universidad Católica de Cuenca., 2021) Luna Rojas, Mirely Cecibel; Rubio Arias, Pablo Geovanni; 0604071902
    Canine 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.
