[Comparison between anticoccidial effect of granulated Artemisia siberi extract and pure Artemisinin in affected broilers]

ABSTRACT

Increasing resistance against conventional anticoccidial drugs and the consequence of their residues has paid the attention toward more effective and safe compounds. Artemisia plant is a potential candidate that its anticoccidial effect has been previously discussed. This study aimed to produce a granule from the extract of Artemisia siberi and evaluate its anticcocidial effects compared to pure Atremisinin. Artemisinin was extracted from Artemisia by petroleum ether and then formulated into a wet granule. Experimental coccidiosis was induced in chicks [n=75] by oral administration of 250000 oocysts/chick. Chicks were divided into 5 groups of three replicates each [n=15] and one uninfected group [n=15]. The infected chicks were treated by oral administration [lmg/kg] of pure artemisinin and granule formulation with three different doses [1, 2.5 and 5mg/kg artemisinin] as feed additive. The treatment was conducted for 5 successive days towever. The fifth infected group and uninfected group did not receive any medication. At the end of treatment, fecal samples of each group were collected for 5 days and the OPG [oocyst per gram] was determined as anticoccidial index. The granule formulation of Artemisia and pure artemisinin significantly [p<0.001] decreased the OPG values in treated groups [30% in treated groups Vs8% in control]. However, there wasn't significant difference between granule formulation and pure artemisinin on OPG reduction [30.39% and 30.35%, respectively]. This study showed that the Artemisia siberi granulated extract can be considered as a new effective and safe anticoccidial drug
