Significant Impact Group(s): Prudent use AB \ Farmer ; Biosecurity
Species targeted: Pigs;
Age: Young; Adult;
Outcome Parameter(s): Presence of ESBL-E. coli; antimicrobial use; cephalosporin use at the farm
Summary: This study determined prevalence of ESBL-E. coli on pig farms and the effect of reducing veterinary antimicrobial use (AMU) and farm management practices on ESBL-E. coli occurrence on pig farms. During 2011 and 2013, 36 Dutch conventional pig farms participated in a longitudinal study (4 sampling times in 18 months). The number of farms with ESBL-E. coli carrying pigs decreased from 16 to 10 and the prevalence of ESBL-E. coli-positive pig samples halved from 27% to 13%.
The presence of ESBL-E. coli carrying pigs was not related to total AMU, but it was strongly determined by the presence or absence of cephalosporin use at the farm. Other farm management factors, related with improved biosecurity, were less frequently seen in ESBL-E. coli-positive farms (e.g. presence of a hygiene lock, pest control delivered by a professional). In conclusion, ESBL-E. coli prevalence decreased in pigs during 2011 and 2013 in the Netherlands.

51 Effects of Reducing Antimicrobial Use and Applying a Cleaning and Disinfection Program in Veal Calf Farming: Experiences from an Intervention Study to Control Livestock-Associated MRSA (Research paper; Dorado-Garcia, 2015)

Significant Impact Group(s): AMU reduction strategies ; Biosecurity
Species targeted: Dairy;
Age: Young;
Outcome Parameter(s): decrease in MRSA prevalence
Summary: A Dutch policy was set in place in 2010 promoting a reduction of antimicrobial use (AMU) in food-producing animals. In this context, a study evaluated 2 different strategies: a. with reducing of antimicrobials and b. with reduction of antimicrobials and with a cleaning and disinfection program. These results suggest that AMU reduction might be a good strategy for reducing MRSA in veal calf farming, however the effect of the cleaning and disinfection protocol used in this study was not effective. The study indicates that the long term AMU decrease is likely to lower MRSA levels in people living and/or working in veal farms.

Significant Impact Group(s): Pathogen management \ Managing sick animals \ Targeted use of antibiotics ; AMU reduction strategies
Species targeted: Dairy;
Age: Adult;
Outcome Parameter(s): Udder health status
Summary: The goal of this study was to identify a scenario with the lowest costs for mastitis associated with the dry period while restricting the percentage of cows that need to be dried off with dry cow antimicrobials. The costs of clinical/subclinical mastitis and the antimicrobial use were quantified. The economic impact of reducing the percentage of clinical mastitis was found to be much larger than reducing the bulk tank somatic cell count. The optimal percentage of cows to be dried off with antimicrobials depends on the udder health situation, expressed as the bulk tank somatic cell count and the occurrence of clinical mastitis. Selective dry cow treatment was economically more beneficial than blanket dry cow treatment, for all types of herds studied. Economic profits of selective dry cow treatment are greater if bulk tank somatic cell count and clinical mastitis incidence are lower.

Significant Impact Group(s): Feed / gut health \ Early feeding (colostrum/feed) – Early feeding (colostrum/feed)
Species targeted: Dairy;
Age: Young;
Summary: Survey about colostrum:
When colostrum is infected with Mycobacterium avium subsp. paratuberculosis (MAP), 90% of the germs can be eliminated on-farm using a curdling process. When an externally-located centrifugation treatment is used, this rate increases to 98%. Both methods keep the required amounts of life-sustaining bioactive proteins while the prevention of intestinal infections is strongly reduced.
From the project results, it appears that farmers whose cattle have a limited infection can treat their colostrum on farm. For heavier infections external treatment is recommended.

Outcome Parameter(s): Effects social and/or public health positively.
Summary: This demonstration project is executed by Inagro in cooperation with ILVO. PDCA (which means: Plan Do Check Act) for dairy farmers is its main topic. With the PDCA-principle a dairy farmer can develop a list with action point to work on, focused on colostrum- and transition management. Together with the farm veterinarian, advisors and other important people they create a strength-weakness overview of a farm. Based on this overview the farmer starts working with the PDCA-principle.

Outcome Parameter(s): Immune response in dairy cattle
Summary: Dairy cows face very high metabolic demands have increased difficulties adapting to the environment. This leads to increased replacement rates and frequent occurrence of diseases and drug use. This article reviews how a good understanding of the immune system is crucial in managing mastitis in dairy cows.

Significant Impact Group(s): Breeding for disease resistance or robustness
Species targeted: Dairy;
Age: Adult;
Outcome Parameter(s): Bacteriogical status; Mammary immune response; colostrum protein profile
Summary: A multidisciplinary approach was applied to compare innate immune response patterns, metabolic parameters, milk protein profiles and the milk microbiota in Holstein Friesian and Rendena cows reared in the same farm and under the same management conditions. Results show that Holstein Friesian and Rendena cows have different metabolic traits. Mastitis markers are higher in Holstein Friesian milk. The microbiota biodiversity is lower in Rendena milk. The colostrum protein profile is markedly different in the two breeds. Mammary innate immune response patterns display breed-specific differences. The observations reported in this work present numerous pointers to the factors that may provide more rustic breeds with a higher resistance to disease.
