Microbiology of Pigs and their Environment in Relation to Weaning

摘要: Summary. On weaning, pigs were placed in a house of type which is commonly used for early weaning or individually cages controlled environment room. Micro-organisms (11,631 isolates) recovered from air, food, faeces, water and pigs' skins characterized identified at the genus level. Pigs harboured populations lactobacilli haemolytic serotypes Escherichia coli greater than those their littermates housed conventional piggery early-weaning house. This was ascribed to heavy faecal contamination food troughs caged pigs, since air contained fewer micro-organisms that piggery. The association high numbers E. coli, confinement not associated with same amount clinical disease growth depression as combination smaller organisms housing.
