Abstract
Objective:The present study was aimed to evaluate dose-dependent effects of phytobiotic (Galibiotic) supplements in feed on growth performance, hematological parameters, intestinal pH, and gut bacterial population in broiler chick.Materials and Methods:A total of 50 ten day old broiler chicks were divided into five groups, namely, Group A as control (without galibiotic), Group B (galibiotic at 1 gm/kg feed), Group C (galibiotic at 2 gm/kg feed), Group D (galibiotic at 5 gm/kg feed), and Group E (galibiotic at 10 gm/kg feed). All the birds were reared for 42 days and samples were collected before and after sacrifice.Results:Live body weights showed no significant differences between the groups but overall feed conversion ratios (FCRs) of treatment groups were significantly low in Group E having the lowest. Blood samples collected for hematology differed significantly (p < 0.01) among the different groups. Intestinal pH was lower in treatment groups with Group E having the lowest. Cecal total viable count was highest in Group A and lowest in Group E. The cecal coliform count was low in all the treatment groups.Conclusion:Along with previously published report, it may conclude that the phytobiotic could be used as an alternative to antibiotics due to positive growth performance, lower FCR, carcass quality, and improved gut health of broiler chicks.

Antibiotics use in livestock production as growth promoters have paved the way for the emergence of resistant bacteria many of which are pathogenic to humans [1]
Plate count agar (PCA) media was used for total viable count (TVC); Eosin Methylene Blue (EMB) agar media was used for total coliform count (TCC) and Salmonella-Shigella agar (SS agar) media was used for total Salmonella count
Summary
Antibiotics use in livestock production as growth promoters have paved the way for the emergence of resistant bacteria many of which are pathogenic to humans [1]. Crossresistance and co-resistance of antibiotics in pathogenic bacteria have been strongly linked to therapeutic and/or prophylactic uses of antibiotics in human and veterinary practice [2]. Due to possible negative consequences to human and animal health as well as food safety, several countries have banned the use of antibiotics as growth promoters in recent years [3]. In recent years, gut health of poultry has been the area of intense studies for demanding increase poultry production [5]. Impaired gut function causes poor digestion, absorption of nutrients, and poor performance which affect
