The Efficacy Of Escherichia Coli Aroa-Live Vaccine In Broilers Against Avian E. Coli Serotype O78 Infection, Visut Rawiwet, Niwat Chansiripornchai
The Thai Journal of Veterinary Medicine
The efficacy of an Escherichia coli (E. coli) aroA-live vaccine in the prevention of colibacillosis in chickens following intratracheal challenge with a virulent strain of E. coli O78 was investigated. Thirty-six, one day old broiler chickens were divided into 3 groups of 12 each. Chickens in each group were randomly divided into 2 replicates. The chickens in group 1 that were not vaccinated and challenged served as a negative control. The chickens in group 2 that were not vaccinated but received E. coli serotype O78 served as a positive control. The chickens in group 3 were vaccinated by the oral …

Medium chain fatty acids (MCA) are one of new additives used to control Salmonella infection and it is interesting to examine their physiological role in chickens comparing with other additives. The objective of this investigation was to study the effect of MCA, mixed organic acids (ORA) and fructo-oligosaccharide (FOS) on cecal Salmonella enterica serovar Enteritidis colonization and physiological changes of intestine in broilers. Six hundred, day old, male and female broiler chicks were allocated into 4 treatments. The treatments were CON: basal corn-soybean meal diet, FOS: basal diet supplemented with 4 g/kg FOS, ORA: basal diet plus water supplemented with …
Comparative Efficacy Of Enrofloxacin And Oxytetracycline By Different Administration Methods In Broilers After Experimental Infection With Avian Pathogenic Escherichia Coli, Niwat Chansiripornchai
Comparative Efficacy Of Enrofloxacin And Oxytetracycline By Different Administration Methods In Broilers After Experimental Infection With Avian Pathogenic Escherichia Coli, Niwat Chansiripornchai
The Thai Journal of Veterinary Medicine
The aims of this study were to compare the efficacy of 2 kinds of antibiotics that are commonly used in the Thai broiler industry and to determine the optimal times of drug administration. One hundred and sixty, 21-day-old broilers were divided into eight groups. Chickens in groups 1, 2 and 3 were challenged with avian pathogenic E. coli (APEC) and received oxytetracycline for the first 3 days after infection via oral, drinking water within 2 h and drinking water throughout the day, respectively. The chickens in groups 4, 5 and 6 were challenged with APEC and received enrofloxacin for the …
