This study compared the effects of Sapindus rarak microparticles (SRMs), provided through feed or drinking water, with commercial anticoccidial and antibacterial agents. The goal was to determine which would reduce Eimeria sp. oocysts and Escherichia coli populations and improve chicken performance. Three hundred seventy one-day-old Ross broilers were randomly assigned to seven treatment groups with replicates of nine birds each. The birds were reared for 28 days. The T1 group served as a control; T2 was provided anticoccidial/COXI at 2.5 g/L in the drinking water; T3 was fed antibacterial Zn-bacitracin at 0.5 g/kg feed; T4 and T5 were fed SRMs at 0.63 g/kg and 1.25 g/kg feed, respectively; and T6 and T7 were provided SRMs at 0.3 g/L and 0.63 g/L in the drinking water, respectively. Bodyweight, feed consumption, feed conversion, oocysts per gram faeces (OPGs), E. coli number, and mortality were recorded. The results showed no significant (P > 0.05) difference between the treatments on broiler performance, OPGs, and E. coli numbers. Mortality during the study was only 0.53%. Thus, SRMs provided at levels up to 1.25 g/kg of feed ANDWERE 0.63 g/L of drinking water were not significantly different from COXY and Zn-bacitracin in affecting broiler performance, and in reducing OPGs and E. coli numbers.
