Comparative clinicopathological studies on the effect of different probiotics in broilers

Research Abstract

This study was designed to compare between Bactocell and Revitilyte-PlusTM as probiotics and their effect on the general performance, hematological parameters, biochemical constituents of blood and immune response of broilers. Three hundred one day old broiler chicks were included in this study which were divided equally into six groups (each 50 chicks) as follow: group (C) fed on a balanced ration and considered as the control group, group (L) fed on a balanced ration with probiotic (1) supplementation (Revitilyte-PlusTM at a rate of 1 g/4 liter of water). group (P) fed on a balanced ration with probiotic (2) supplementation (Bactocell, at a rate of 1kg/ton ration), group (C+S) fed on a balanced ration and in the 5th week of age was infected with 8 x 1012 Salmonella kentucky for 2 successive days (1ml in the first day and 0.5 ml in the second day) , group (L+S) fed on a balanced ration with probiotic (1) supplementation (Revitilyte-PlusTM at a rate of 1 gm/4 liter of water) and in the 5th week of age was infected with 8 x 1012 Salmonella kentucky for 2 successive days (1ml in the first day and 0.5 ml in the second day), group (P+S) fed on a balanced ration with probiotic (2) supplementation (Bactocell, at a rate of 1kg/ton ration) and in the 5th week of age was infected with 8 x 1012 Salmonella kentucky for 2 successive days (1ml in the first day and 0.5 ml in the second day). The period of experiment extended to7 weeks through which weighing of birds and collection of samples was done. Results revealed that Bactocell is better than Revitilyte-PlusTM as a probiotic as it increased the body weight , improved the FCR , provided more immunoglobulins and lower mortalities than Revitilyte-PlusTM.
