Item Efectos de la harina de hojas de brócoli (Brassica oleracea) en los índices productivos y niveles de inmunología A sérica de terneros lactantes(2024-08) Claudio Terán, Katy Anabel; Burgos Mayorga, Ana RafaelaThe aim of this research was to evaluate the addition of B. oleracea in the diet of lactating calves. Three treatments were applied: control with 0 g (no addition), treatment 1 with 10g, and treatment 2 with 20g. Live weight, weight gain, feed consumption, feed efficiency index, immunoglobulin A in serum, and feces consistency were evaluated to find the treatment with the best performance. Twelve calves were allocated in one of the three treatments, each one ended up with four animals. The research was carried out for six weeks, data was collected once daily for feeding consumption and feces, once per week for weight parameters, and two blood samples for serum IgA (the first and the last day of the experiment). Best results were observed with treatment 2 (addition of 20g of B. oleracea) with live weight at week 7 of 69.38kg (p=0.02), weight gain of 33kg (p=0.04), and feed efficiency index of 5.65 (p=0.05). Besides, serum immunoglobulin A at week 7 was greater than other treatments with a mean value of 95.43mg/dL (p=0.0002), and feces consistency was into category 4 which is the ideal for these animals. In conclusion, the addition of 20g of B. oleracea in the diet of suckling calves can increase serum IgA levels and improve productive parameters.Item Incidencia de Toxocara canis y Dipylidium caninum en la parroquia La Matriz – Quero(2023-09) Solís Constante, Karen Alexandra; Villavicencio Villavicencio, Blanca JeanethThe objective of this study was to establish the incidence of Toxocara canis and Dipylidium caninum in domestic dogs in the parish of La Matriz - Quero. The methodology used was descriptive observational with a qualitative and quantitative analysis, a survey was applied to citizens to obtain the sample size which was 263 dogs whose feces were evaluated by the direct method and the Sheather Sugar flotation method, 71 positive cases of Toxocara canis were identified with an incidence of 32% and 10 positive cases for Dipylidium caninum with 3%. Parasitosis due to Toxocara canis affected more puppies (<1 year) with 79% compared to adult canines (1-7 years) with 21%. Chi-square showed that Toxocara canis parasitosis affected puppies regardless of sex, with no significant difference between females and males with 51% and 49%, respectively. In the case of Dipylidium caninum, 70% represented males and 30% females, in addition, adults (1-7 years) showed 70% parasitosis in contrast to puppies (<1 year) with 20%; it was also determined that there is no relationship between parasitosis, age and sex of the host by means of Chisquare. With the use of the McMaster chamber, levels of parasitosis >500 h.p.g. were obtained, which is considered severe parasitosis. Thanks to this study, the importance of carrying out deworming protocols and informing owners of the risk of not taking preventive measures against zoonotic agents is evident.
