“…An Indian study (Sn105) 113 , comparing intensive farms vs. farms were animal had access to grazing, found that fecal bacteria from intensive farms were characterized by higher prevalence of AMR, which was also affected by feeding practices and nutrient concentration. Two studies, conducted by the same research group in Belgium (Sn103-Sn104) 112 , focused on AMR profiles of both E. coli , (retrieved from the rectum) and Pasteurellaceae bacteria (retrieved from the nasal cavity) found a strong relationship between antimicrobial treatment and resistance profiles of bacterial isolates, in particular on intensive farms.…”

A common thought is that extensive and organic breeding systems are associated with lower prevalence of infections in livestock animals, compared to intensive ones. In addition, organic systems limit the use of antimicrobial drugs, which may lead to lower emergence of antimicrobial resistances (AMR). To examine these issues, avoiding any a priori bias, we carried out a systematic literature search on dairy cattle breeding. Search was targeted to publications that compared different types of livestock farming (intensive, extensive, conventional, organic) in terms of the circulation of infectious diseases and AMR. A total of 101 papers were finally selected. These papers did not show any trend in the circulation of the infections in the four types of breeding systems. However, AMR was more prevalent on conventional dairy farms compared to organic ones. The prevalence of specific pathogens and types of resistances were frequently associated with specific risk factors that were not strictly related to the type of farming system. In conclusion, we did not find any evidence suggesting that extensive and organic dairy farming bears any advantage over the intensive and conventional ones, in terms of the circulation of infectious agents.
