Abstract
Coccidiosis, caused by Eimeria spp., is a major economic burden in poultry production, prompting growing interest in natural alternatives to synthetic anticoccidials. This study evaluated the use of Polygain™, a sugarcane-derived polyphenol-rich feed material, as a natural anticoccidial in broiler chickens experimentally challenged with Eimeria tenella, E. maxima, and E. acervulina. A total of 144 Ross 308 chicks were allocated to six groups: uninfected–untreated control, infected–untreated control, infected plus nicarbazin + narasin, and three Polygain™ treatment groups (250, 500, and 1000 ppm). Birds were orally challenged with mixed oocysts on day 14. Parameters assessed included body weight gain (BWG), lesion scores (LS), oocyst per gram (OPG), and calculated indices such as relative oocyst production (ROP), reduction in lesion score (RLS), percent optimum anticoccidial activity (POAA), and anticoccidial index (ACI). Polygain™ reduced intestinal lesions (p < 0.05), particularly in the caecum, with complete lesion resolution observed at 1000 ppm by 21 days post-infection. Polygain™ ACI values (143–146) were limited in comparison to nicarbazin + narasin treatment (ACI 160). These findings demonstrate that Polygain™ supplementation confers measurable protective dose related effects against coccidiosis without impairing growth performance, supporting its potential as a natural feed material for integrated coccidiosis management.
