Abstract

Objectives: This study aims to investigate the effectiveness of feeds containing sambiloto extracted in water (SWE) or ethanol (SEE) in improving the performance of broilers infected with Eimeria sp.
Material and Methods: A total of 80 ROSS 308 strain day-old chicks were divided into 4 groups: groups FSWE and FSEE (chickens infected with Eimeria sp. and fed with basal feed containing SWE and SEE, respectively), group F+ (chickens infected and fed basal feed), and group F– (chickens not infected and fed basal feed). Infection was performed on day 14 by oral administration at a dose of 3×104 oocysts for every chick. Body weight gain, feed conversion ratio (FCR), and survival rate were calculated during the treatment period. Anticoccidial efficacy variables were measured based on the oocysts per gram (OPG), oocyst ratio, oocyst value, and lesion scoring. Data were analyzed using one-way ANOVA and the Kruskal-Wallis test.
Results: The performance study results indicated that the highest body weight was achieved by the FSWE, and an ideal FCR was obtained from the FSEE, respectively. The lowest oocyst count was obtained in FSWE (p < 0.05), and the highest survival rate was observed in FSEE.
Conclusions: The study concluded that SWE and SEE have anticoccidial efficacy in broilers and offer benefits as feed additives in preventing Eimeria sp. infections.
