    (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.
