    Efecto de la harina de cúrcuma (Cúrcuma longa) y romero (Rosmarinus officinalis) en los índices productivos y coccidiosis en pollos de engorde
    (2024-08) Medina Vera, Pamela Alexandra; Guerrero López, Jorge Ricardo
    The objective of this study was to evaluate the addition of turmeric (C. longa) and rosemary (R. officinalis) in different doses, on the productive indices and the oocyst count of Eimeria spp, for this we worked with nine treatments, each combined according to the established dose, being for C. longa (0, 0.02, 0.05 %) and R. officinalis (0, 0.05, 0.1 %) respectively. For the study, 270 one-day-old Cobb 500 mixed chickens were used. By means of the completely randomized DCA design with factorial arrangement with 3 replicates for each treatment and 10 animals per repetition. The data were evaluated with the statistical program Infostat by means of the Tukey test at a significance level of 95%. The analysis was carried out in three different stages (initial, growth and fattening) respectively, while the measurements for the evaluation of oocysts of Eimeria spp were carried out in 3 periods (27, 35 and 48 days of age) respectively. Regarding the results, there were no significant differences greater than (P>0.05) in the production indices: Final weight (g), Weight gain (g), Feed intake (g), AQI (g/g), IEE, Mortality %, Cost/Benefit (C/B). In relation to the evaluation of oocysts of Eimeria spp., statistical differences could be observed in the intake at 48 days of age, the treatment that obtained a better result was T5 with an average of 29.17 oocysts/g of feces.

    Evaluación de la eficacia in vitro del aceite esencial de romero (Rosmarinus officinalis) como control natural de pulgas en caninos domésticos (Canis lupus familiaris)
    (2024-08) Aguilar Zapata, Jordi Pau; Vásquez Freytez, Carlos Luis
    In the field of human health, pest control has always been very important both in the care of crops and in the fact that they become one of the main factors of disease transmission, with the flea becoming an important vector for the transmission and how to trigger many diseases. Due to this problem, a countless number of insecticides have been created, which due to constant and misuse have created fleas resistant to them, for this reason, this research seeks to evaluate the in vitro effectiveness of rosemary essential oil (Rosmarinus officinalis ) as a natural control of fleas in domestic canines (Canis lupus familiaris). 90 fleas were collected using the fine comb technique, which were subjected to different rosemary treatments (1%, 2%, 4%, 8%) as well as a positive control (Fipronil) and a negative control (distilled water). The fleas were identified as Ctenocephalides felis, based on the morphological characteristics of the head and antennae. In relation to the effectiveness of rosemary oil, it was found that the mortality rate increased with increasing concentration. The highest mortality rate was obtained when rosemary essential oil was used at a concentration of 8%, reaching 50% after 1 hour of application and after 24 and 48 hours mortality reached 100%. Based on the results, it is suggested to carry out in vivo effectiveness evaluations to determine its safety on dogs.
