Abstract
The efficacies of probiotic with regard to clearing bacterial infections and regulating the gut flora have been clearly demonstrated in this study. One hundred day old broiler chicks were randomly divided into four groups as group A (Vaccinated probiotics fed group), B (Non-vaccinated probiotics fed group), C (Vaccinated conventional fed group) and D (Non-vaccinated conventional fed group). Groups A and B were taken as experimental birds fed with commercially available feed with the addition of probiotics as per schedule whereas groups C and D were taken as control birds fed with commercial ration. The ratio of total viable count (TVC) and total lactobacillus count (TLC) obtained from the bacteriological examination of cecum samples of probiotics fed group (vaccinated and non-vaccinated) at the 2nd, 4th, and 6th week of age were 1:0.96 and 1:0.94; 1:0.97 and 1:0.98; 1:0.99 and 1:0.99 respectively and 1:0.39 and 1:0.41; 1:0.43 and 1:0.43; 1:0.44 and 1:0.41 for conventional fed group (vaccinated and nonvaccinated) respectively. The recovery of TLC obtained from the cecum samples of probiotics and conventional fed broilers were found always on the increase in probiotics fed broilers as compared to conventional fed broilers at the 2nd, 4th and 6th week of age. The present research suggests that vaccination of broilers has no influence on the propagation of intestinal microflora. DOI: http://dx.doi.org/10.3329/ralf.v1i1.22362 Res. Agric., Livest.

Highlights
Antibiotic feed supplements have been used in commercial poultry farming for over 50 years due to their growth-promoting and prophylactic properties (Bunyan et al, 1977; Coates et al, 1963; Forbes and Park, 1959)
When 108 CFU Lactobacillus salivarius, CTC2197 was dosed by oral lavage together with 106 CFU Salmonella enteritidis directly into the proventriculus in 1-day-old chicks, the Salmonella bacteria were completely removed from the birds after 21 days (Pascual et al 1999)
Group I comprised 50 broiler chicks which belonged to probiotics fed group (PFG) and the remaining in group II comprised 50 broiler chicks which belonged to conventional fed group (CFG)
