Abstract

This study was conducted to evaluate algal sulfated polysaccharides (SP) as replacement for antibiotic growth promoters (AGP). A total of 400 chicks were randomly assigned to 4 treatments namely: (1) basal diet, (2) basal diet + water - soluble AGP, (3) basal diet + SP A, and (4) basal diet + SP B. No significant differences were observed in body weight gain, average daily gain,feed intake, feed gain ratio, and mortality percentage of the birds among all the treatments. Moreover, differences in villi height and crypt depth of the three portions of the small intestine were not significant. In the ileum and jejunum, antibiotic supplementation significantly increased villi width and mucosal thickness. Supplementation of SP resulted in higher margin over feed custom. SP is a good AGP replacer in broiler production.
