Dietary use of Artemisia herba alba Asso as a potential coccidiostat against cæcal coccidiosis: haematological parameter variations.

This study consists of the evaluation of the anticoccidial effect of Artemisia herba-alba Asso during experimental coccidial infection. Four groups of 30 broiler chickens were formed: the negative control (G1), the positive control (G2), the infected Monensin-treated group (G3), and the infected Artemisia-treated group (G4). Each infected bird received orally 105 sporulated oocysts of Eimeria tenella. No mortality was recorded in both G1 and G4. Haematocrit levels showed great variations from the 7th day post-infection, especially in G2 (20.87% ± 5.77). By day 10 P-I, haematocrit recovery was rapid particularly in G4 (28.07% ± 1.50). Haemoglobin concentration also decreased significantly (p < 0.05) in all infected groups by the 7th day P-I. The reduction was very marked, but not statistically significant, in G2 (6.47 g/dL ± 1.67) against (10.53 g/dL ± 0.25) in G1. It was less marked in G4 (8.05 g/dL ± 1.56). Results show the protective effect of A. herba-alba Asso by improving the lesion score and the haematological parameters affected during coccidian infection.
