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
Summary: Bad udder health management threatens human health due to zoonotic or antimicrobial resistant pathogens adapting to different environments. Mastitis prevention is essential in an effective and sustainable dairy production system. High quality milk with low SCC is crucial for product quality for the processing industry (cheese making). This will result in a reduction of food loss and food waste by producers, processors and consumers. Mastitis is one of the most frequent and important diseases in bovine milk production with high antimicrobial usage and a source of creating a potential acceleration on the emergence of antimicrobial resistance. The presented results will discuss data collected at country level on mastitis therapy and examine strategies to improve udder health for a sustainable dairy production.

Significant Impact Group(s): AMU reduction strategies \ Monitoring and surveillance \ Antibiotic use ; Pathogen management
Species targeted: Dairy;
Age: Young; Adult;
Outcome Parameter(s): Antimicrobial usage; Disease prevalence
Summary: Antimicrobial use in dairy cows and calves was estimated using standardized drug usage indicators in Argentina. In lactating dairy cows, intramammary usage accounted for the majority of total drug usage. All the surveyed disease cases in calf rearing units included treatment with antibiotics.

61 Effect of udder health management practices on herd somatic cell count (Research paper; Dufour, 2011)

Significant Impact Group(s): Pathogen management \ Managing sick animals ; Housing and welfare
Species targeted: Dairy;
Age: Adult;
Outcome Parameter(s): herd somatic cell count
Summary: Thee scientific literature on relationships between management practices used on dairy farms and herd somatic cell count (SCC) is reviewed in this study. A large number of management practices have shown consistent associations with herd-level SCC when used in usual dairy settings. These practices should be the basis of udder health recommendations to dairy producers. Although many management practices have shown interesting associations with SCC, the lack of consistency observed should moderate reliance on their use.

60 Strategies for reduced antibiotic usage in dairy cattle farm (Research paper; Trevisi, 2014)

Significant Impact Group(s): Pathogen management \ Managing sick animals \ Targeted use of antibiotics ; AMU reduction strategies
Species targeted: Dairy;
Age: Adult;
Outcome Parameter(s): Inflammatory response
Summary: A proper combination of herd data on opportunistic diseases and of farm-specific risk factors can lead to a substantial reduction of antibiotic usage in dairy farms. In this respect, the proper combination of clinical inspections, animal-based welfare parameters and predictive laboratory tests can give clues as to the environmental adaptation of dairy cows and define the animals at risk. The greater potential for disease control in the herd can justify the adoption of such a strategy on a sound cost/benefit basis.

48 Economic optimization of selective dry cow treatment (Research paper; Scherpenzeel, 2018)

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.

44 Somatic cell count as a decision tool for selective dry cow therapy in Italy (Research paper; Zecconi, 2018)

Species targeted: Dairy;
Age: Adult;
Outcome Parameter(s): Udder health status
Summary: It is crucial to define a consistent and approved procedure to identify cows that need to be treated in a selective dry cow therapy approach. Somatic cell counts (SCC) from milk test records are a convenient, accurate and certified method. SCC values obtained before drying off or calculated as the average of lactation records can be used. The thresholds of 100,000 cells for primiparous cows and of 200,000 cells for pluriparous cows are suggested as an efficient and sustainable decision tool.

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.

Significant Impact Group(s): Breeding for disease resistance or robustness ; Pathogen management
Species targeted: Dairy;
Age: Adult;
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.

Species targeted: Poultry;
Age: Young;
Summary: Altitude has developed the H@tch Vet Expert application. This application, developed for the Merial and Chêne Vert Conseil laboratories, is intended to be used during audits in hatcheries.
Veterinarians fill out a predefined questionnaire in the application during their visit to the farm. This questionnaire, the responses of which appear in the form of notes, text, multiple choice questions, etc. then makes it possible to create statistics but also to position the farms in relation to previous audits or in relation to other farms of the same type.
The questionnaires and statistics can be managed from the application but also from the website.
