Different combinations of peppermint, chamomile and a yeast prebiotic have different impacts on production and severity of intestinal and bursal abnormalities of broilers challenged with coccidiosis

Various mixtures of two phytogenics and a prebiotic were assessed for their impacts on performance Ross 308 broilers experimentally challenged at 8 d-of-age with Eimeria tenella sporulated oocysts. The seven treatment groups (4 pens/treatment, 10 chicks/pen) were: Negative Control, unchallenged, un-supplemented; Positive (C), C P + CH, challenged, supplemented (per kg diet) 5 g peppermint (P) chamomile (CH); Y, yeast cell wall (YCW) product; CH YCW; each P, Sal, 60 mg salinomycin (Sal)/kg diet. At 24 35 d-of-age, all had higher weight gains (p ? .0001) lower feed conversion ratios .05) to Controls. 2 chicks/pen killed. Groups Y intestinal relative weights than other treatments .0001). Controls significantly shorter villi, deeper crypts, villus height:crypt depth thicker jejunal muscle treatments.
