| Popis: | Coccidiosis is the most important intestinal parasitic disease of broiler chickens in poultry industry. Because of the increasing resistance to anticoccidial agents and presence of their residues in meat and eggs, it is necessary to find safe and new anticoccidial compounds. This study was conducted to com-pare the effects of two herbal compounds, including Artemisia sieberi and Curcuma longa, and their mix with a chemical anticoccidial drug on broilers’ performance during a mixed coccidian challenge. A total of 216, one-day-old Ross 308 broilers were randomly divided into six groups. Different herbal extracts and one chemical anticoccidial agent were used in each group. Five groups were infected with a mixture of Eimeria sporulated oocysts at the age of 21 days with crop gavage. Body weight and feed intake were measured then feed conversion ratio was calculated on a weekly basis. Mortality was recorded when occurred throughout the experimental period. Oocysts excretions and lesion scores were investigated weekly up to three weeks after infection. Eimeria-challenged birds had a reduction in growth parameters compared to the uninfected birds (P |
