Virulence Determination of Three Iranian Isolates of Salmonella Enteritidis in Day-Old Layer Chicks
BACKGROUND: Salmonella Enteritidis (SE) infection in poultry is one of the most important concerns in poultry. Virulence and pathogenicity of the SE isolates from Iran have not been well studied so far. OBJECTIVES: In the present study, three Salmonella Enteritidis (SE) isolates were compared with a standard SE strain (PT21) for virulenc...
متن کاملSexing Day-Old Chicks on Small and Backyard Flocks

متن کاملThe Physiological Responses to Dietary Administration of Zinc Bacitracin and Bacillus Mixture on Low-Weight Day-Old Chicks
This study investigated the responses of low-weight day-old chicks to zinc bacitracin and Bacillus mixture on growth performance, hematology, intestinal selected microbiota populations, and carcass characteristics. A total of 192 unsexed Lohman MB-202 day-old broiler chicks were randomly allotted to four dietary treatment groups of 48 chicks each (6 replicates of 8 chicks) and fed for 35 days. ...
متن کاملStudy of the infectivity of saline-stored Campylobacter jejuni for day-old chicks.
The culturability of three Campylobacter jejuni strains and their infectivity for day-old chicks were assessed following storage of the strains in saline. The potential for colonization of chicks was weakened during the storage period and terminated 3 to 4 weeks before the strains became nonculturable. The results from this study suggest that the role of starved and aged but still culturable ca...
