Abstract: Bacterial enteritis induced by oral administration of 2 ml E.coli and Salmonella typhi suspension (109 organisms ml-1) showed negative effect on the growth rate of broiler chicks and 140 ml bacterial suspension was also mixed in drinking water. Bio-Mix (a herbal extract of A.B. Pharma) was used against bacterial enteritis, after 24 h @100 gm/50 kg feed for 7 days controlled the disease, i.e. loose dropping, less feed intake with reduced growth rate was found in diseased birds as compared to treated (Bio-Mix) and control. It was observed that the diseased birds showed loose dropping and less feed intake. The weekly weight gain record showed significantly (P<0.05) reduced growth rate as compared to healthy birds.
