- ÍtemAcceso AbiertoConsumo de tortas protéicas para abejas con la adición de aceites esenciales de cedrón, manzanilla y toronjil(Universidad Católica de Cuenca., 2024) Muñoz Ortiz , Federico Xavier; Cuenca Condoy, Mercy del Cisne; 0103900288The study evaluated the consumption of base protein cakes with the addition of essential oils in Apis Mellifera bees, using four hives distributed in a 4 x 4 design, with four treatments: T0 (Control Base cake), T1 (Cedron cake), T2 (Lemon balm cake), and T3 (Chamomile cake) for 30 days, with a rotation frequency of 7 days, an adaptation period of seven days, using video surveillance system to determine food preference outside the hives. The variables analyzed were feed consumption, consumption time, and palatability of the protein cakes. The analysis of results showed a significant difference (p<0.05) in feed consumption, with the highest feed consumption for treatment T3 (chamomile cake) at 31.30 g/day and the lowest consumption for T1 (Cedron cake) at 5.10 g/day. Regarding the preference or palatability of the cakes outside the hive, there was a significant difference between treatments (p<0.05) being more palatable the cake enriched with chamomile oil at 31.28 g/day. It is concluded that using medicinal plant oils, particularly chamomile essential oil, significantly improves the palatability of protein cakes intended for bee (Apis mellifera) consumption. Keywords: Apis mellifera, Protein Cake, Essential oil, Lemon balm, Chamomile, Cedron.
- ÍtemAcceso AbiertoEfecto de la suplementación con Saccharomyces cerevisiae sobre la morfometría intestinal de cerdos destetados(Universidad Católica de Cuenca., 2022) Juncal Chiqui, John Leonardo; Cuenca Condoy, Mercy del Cisne; 0150381077The objective of the study was to evaluate the effect of Saccharomyces cerevisiae supplementation on intestinal morphometry of weaned pigs. A total of 45 weaned pigs of the Landrace x Pietrain breed, 45 days old, with a mean weight of 17.5 kg (+ 1), were distributed under a complete randomized design in three treatments T0 (control), T1 (0.5% of Saccharomyces cerevisiae), T2 (1 % of Saccharomyces cerevisiae), with three replicates per treatment and 5 pigs per replicate. The variables evaluated were productive parameters (total weight, weight gain, feed intake, and feed conversion) and intestinal morphometry variables (height, width, and some intestinal villi, number and depth of crypt, and wall thickness). The data were analyzed using the statistical program Infostat, version 1.1. The results showed that the addition of S. cerevisiae yeast in the feed ration in pigs at doses of 0.5 and 1% in the growth-finishing stages does not significantly impact the productive parameters of the pigs; however, a decrease in feed consumption and a better cumulative feed conversion were observed with the 0.5% inclusion; on the other hand, there is a relative benefit on the variables of intestinal morphometry by supplementing the feed of pigs with S. cerevisiae. It is concluded that the addition of the yeast in pig diets at 0.5 and 1% had no statistically significant effect on the productive parameters and intestinal morphometry in pigs. Keywords: probiotic, monogastric, histology, productive param
- ÍtemSolo MetadatosImpacto de Saccharomyces cerevisiae sobre el sistema inmunitario en cerdos durante la etapa destete-finalización(Universidad Católica de Cuenca., 2022) Siavichay Cuzco, Alba Mariela; Cuenca Condoy, Mercy del Cisne; 0106993421The present study was carried out to evaluate the impact of Saccharomyces cerevisiae on the immune system, the immune response, and the hematological profile of pigs during the growth-finishing stage; for this purpose, 45 weaned pigs of 56 days of age with an average weight of 17. 38 kilograms, distributed in a completely randomized design; the treatments to be evaluated were T0 (Control), T1 (0.5% S. cerevisiae), and T2 (1% S. cerevisiae), each with three replicates and five experimental units. The variables evaluated were: production parameters (weekly weight, feed intake, weight gain, and feed conversion), serum immunoglobulin levels (IgA, IgG, IgM), hematological profile, and weight of the immune system organs (thymus, spleen, tonsils, mesenteric lymph node). The results obtained showed that the highest weekly weight was reached at T0; the hematological profile of the pigs was not affected, finding these values within normal ranges; the levels of serum immunoglobulins were positively affected with the inclusion of S. cerevisiae at 0.5 and 1%, on IgA and IgG; and finally, tonsil and spleen weight increased with the addition of 0.5%, and thymus and mesenteric lymph node with the inclusion of 1% S. cerevisiae. In conclusion, the addition of 0.5 and 1% of the probiotic does not have a positive impact on production parameters, hematological profile; however, it improves immunoglobulin levels and the weight of the organs of the immune system in swine. Keywords: probiotic, serum immunoglobulins, organ weights, production parameters
- ÍtemAcceso AbiertoNiveles 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; 0106076615This 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.
- ÍtemAcceso AbiertoSaccharomyces cerevisiae en la respuesta productiva y digestibilidad in vivo en cerdos de crecimiento-ceba(Universidad Católica de Cuenca., 2023) Chamba Jaramillo, Jhinson Angel; Cuenca Condoy, Mercy del Cisne; 1900652007The objective of the present investigation was to evaluate the effect of the addition of S. cerevisiae in the diet of pigs in the growing-fattening stage on the productive response and in vivo digestibility. Forty-five Landrace x Pietrain pigs of 45 days of age with an average weight of 18 ± 1 kg, were randomly distributed in three treatments, with three replicates and five experimental units per replicate. Three experimental diets were fed: T0 (Control), T1 (S. cerevisiae 0.5%), and T2 (S. cerevisiae 1%). The pigs under study were subjected to similar zootechnical management in terms of environmental variables, sanitary, and feeding programs. The variables evaluated were productive parameters (feed intake, weekly weight, weight gain, feed conversion) and in vivo digestibility parameters: dry matter (DM), crude protein (CP), and crude fiber (CF) at 12, 24, 48, 72 and 120 hours. The results were analyzed using the statistical package InfoStat version 1.1, showing that there was no difference (p>0.05) between treatments on the productive behavior variables; however, a positive impact was observed on the in vivo digestibility variables for DM, CP, and CF with the inclusion of 1% Saccharomyces cerevisiae. It is concluded that the addition of S. cerevisiae at 0.5 and 1% in the feed ration of pigs in the growing - fattening stages do not have a positive effect on the productive parameters; however, it improves the nutrient digestibility variables.
