Prevalencia De Tumor Venéreo Transmisible (Tvt) En Perros Sexualmente Activos Del Casco Urbano Del Cantón Guaranda, Provincia Bolivar, Ecuador

The present research work was conducted at Scooby Doo Veterinary Clinic in the city of Guaranda-Ecuador. In order to determine the prevalence of transmissible venereal tumor (TVT) in sexually active dogs in the town. According to information provided by the Department of Public Health Surveillance District Health Directorate of Guaranda #201. Based on the last rabies vaccination, the number of animals (universe) was 2508. We use the appropriate statistical formula, its percentage determined by the study in 333 animals, after performing collection and entering data from all patients, we obtained the following laboratory study determining that 180 were females and 153 males. The females were between one and four years old and the males were between one and four years old were infected and did not received any treatment; except in two cases in the downtown area. The remaining cases were found in the peripheral areas were the population is economically depressed. However these results the null hypothesis (Ho) and the alternative hypothesis were rejected (Ha), so it is concluded that: "The Transmissible Venereal Tumor (TVT) is a transmitted sex disease with a low prevalence in sexually active male and female dogs in the town of Canton Guaranda

Evaluación De Tres Niveles De Mananos Oligosacáridos (Sacharomices Cerevisae) En Los Parámetros Productivos Y Salud Intestinal En Pollos De Engorde En El Cantón Babahoyo, Provincia De Los Ríos, Ecuador

The objective of this research was to evaluate different levels of mannans oligosaccharides (MOs) in productive parameters and intestinal health in broilers. Two hundred and forty one-day-old broiler chickens (Ross 308 line) were used during a 6-week experimental period. A completely randomized design with four treatments and six replicates was used. The evaluated levels were 0.0 kg t-1 (T0); 0.5 kg t-1 (T 1); 1 kg t-1 (T2) and 1.5 kg t-1 (T3). For the mean comparisons, a Tukey test (P≤0.05) was used. The source of oligosaccharide mannans derived from the cell wall of Saccharomyces cerevisiae and it was added to the commercial balanced feed. Productive parameters, intestinal villi and economic performance (costbenefit) were evaluated. The data was analyzed with the statistical program SAS V9 (2012). At 42 days of the test, T2 reached the highest average weight of 2455.48 g. For feed consumption, the mean average for T0, T1, T3 and T2 were 4342.63 g, 4304.5 g, 4254.32 g and 4216.80 g respectively. T2 had higher weight gain compare to the control group, 535.70 and 388.84 g, respectively. Feed conversion was higher for T2 (1.71) compared to the control group (1.85). T1 obtained had a carcass yield of 75.89%. Mortality did not show significant differences (P≥ 0.05). Length and width (μm) of the intestinal villi were different (P≤0.05) among treatments, at 21 days of, T3 showed the longest (1939.74 μm) and widest (326.03 μm) measures at the duodenum site. The economic analysis, all the treatments were profitable results, although T1 had the highest cost-benefits ($ 1.30)
