    Abstract: Anticoccidial effects of <I>Magnoliae officinalis</I> Extract 
  (MOE) were evaluated in chickens following oral infection with <I>Eimeria</I> 
  (E.) <I>tenella</I>. This study was conducted on the 3 days old chickens (n 
  = 30). Those animals were divided with 3 groups; MOE 0.5% treated/infected (n 
  = 10), MOE untreated/infected (n = 10) and non-infected control (n = 10). Chickens 
  were fed a standard diet supplemented with or without MOE for 1 week prior to 
  infection with <I>E. tenella</I> (10,000 sporulated oocysts per chicken). The 
  effects of MOE on <I>E. tenella</I> infection were assessed by two parameters, 
  fecal oocyst shedding and body weight gain. The MOE-fed chickens produced significantly 
  reduced fecal oocysts (p&lt;0.05) when compared to the <I>E. tenella</I>-infected 
  group fed standard diet. Also, MOE-based diet, improved body weight loss caused 
  by <I>E. tenella</I> infection. The data demonstrated that MOE had remarkable 
  anticoccidial activities against <I>E. tenella</I>. This finding might have 
  implications for the development of anticoccidial drug.
