    (2021-09) Remache Villacís, Adriana Cristina; Guerrero López, Jorge Ricardo
    A study was carried out where the effect of the essential oil of oregano (Lippia origanoides) on productive parameters in broilers infected with Eimeria acervulina and maxima experimentally at 14 days of age, for which 375 Cobb 500 male chickens were used, divided into 5 groups, with three repetitions, the first received basal diet, but was infected with 1x 105 oocysts each type of Eimeria, the second no oocysts were introduced and the basal diet was maintained, serving these as control groups, the remaining three were challenged against Eimeria, receiving diets with essential oil of oregano (Orego Stim) with doses of 300 and 600 mg / kg for groups 3 and 4, respectively, to the fifth salinomycin (SAL) was added to 60 mg / kg dose. By day 17 all groups show bloody diarrhea, except the SAL group, since those who added oregano to their diet, coccidiosis was lower, compared to the oocyst-infested control group. At 7 days, lesions in the small intestine (proximal and middle) in 9 birds of each replica, whose results indicate less damage for the groups treated with oregano and salinomycin. This shows that the essential oil (AEO) exerts an anticoccidial effect similar to the type of antibiotic evaluated, but more studies are needed to arrive at an effective dose.
