PROBIOTICS FOR THE CONTROL OF SALMONELLA COLONISATION IN FOWL, METHOD OF ISOLATING THEREOF, FEED CONTAINING THE PROBIOTICS

摘要

A composition of anaerobic bacteria inhibiting Salmonella colonisation of domestic animals, in particular fowl is disclosed. The composition includes populations or cultures of 29 substantially biologically pure bacteria. A method for isolating probiotics (bacteria cultures) can be characterised in that: a) droppings, cecal contents or large intestine are combined with a culture medium and incubated without dilution (i.e. batch culture) under anaerobic conditions; b) the resultant culture is subjected to continuous flow conditions at a turnover rate between about 0.029 to about 0.10 hr-1, a pH between about 4.7 to 6.5, until a steady state is achieved; c) after which time the steady state culture may be recovered for use as a probiotic.
