Economic effect of some antibiotic growth promotants withdrawal on pig production cost
Blamed for favouring the outbreak of antimicrobial resistance in bacteria from humans, this use is today thrown into question. In September 1999, the European Union prohibited the use of six…
Publié en 2001A study of the influence of various animal husbandry criteria on the occurrence of PMWS (Postweaning Multisystemic Wasting Syndrome) in an experimental pig farm
Data on PMWS (Post-weaning Multisystemic Wasting Syndrome) were collected over a one-year period on the experimental pig farm located at Romillé. The prevalence of the disease was estimated by autopsying…
