Introduction: The use of antibiotics in Swiss veal production is considered an established method for controlling bacterial infectious diseases. Although the veterinary profession aims to ensure animal welfare, the veterinary business income needs to be ensured at the same time. Against the background of increasing problems with resistant pathogens in human and veterinary medicine, the use of antibiotics should be significantly reduced and used more selectively. The associated economic consequences for food animal practitioners are unknown. The aim of this study was to determine the economic importance of antibiotic sale volume for private food animal practitioners in veal production. An anonymized questionnaire was sent to 120 mixed veterinary practices in Switzerland, which offered services to veal and beef cattle farmers. Questions involved the pharmaceutical sale volume, details on veterinary invoices from three farms with average, below and above average animal health throughout 2017. Twenty-nine complete questionnaires (response rate: 24.2%) and veterinary invoices of 84 farms were returned. The study is not representative, but it allows a rough assessment of the economic framework in Swiss livestock practice. The majority of the total turnover with livestock farms was generated by the sale of antibiotics (54%). Antibiotic sales per animal were higher as expected in farms with a below-average animal health than in farms with an average or above-average animal health. Consulting services turnover contributed only 0.5% to the total sale volume in veal farming. The results document, that antibiotic reduction measurements in veal and beef production will have economic consequences for veterinary livestock practices. In the medium term, the profitable existence of livestock veterinary practice requires a change to cost based consulting services.

The objective of this study was to calculate the national costs associated with udder health in Switzerland and to estimate the cost effectiveness of an udder health intervention program. In 49 farms, yearly mastitis associated costs before and during an intervention were collected at herd level. Costs were calculated for each lactating cow being present in the herd. At the beginning of the intervention, 24 farms received a report with recommendations to improve the udder health. In the following year, those herds were followed-up by their veterinarian at a monthly basis. The other 25 farms were used as a negative control group and neither received any recommendations nor any follow-up. In the first year of analysis (2010), the median udder health associated costs were 209.- Swiss Francs for each lactating cow, regardless of the intervention group. During the intervention period (2012), mastitis associated costs were 191.- Swiss Francs for control farms and 396.- Swiss Francs for farms with veterinary intervention on a monthly basis. The median additional costs for herds with intervention were 159.- Swiss Francs per lactating cow. At the national level, mastitis associated costs were estimated at 129.4 millions of Swiss Francs per year. The cost effectiveness of future mastitis control programs can be evaluated with the help of the deterministic model developed during this study.

Comparing data from three cross-sections of the German Socio-Economic-Panel (1984, 1988, 1992), migrants who had come to Germany until 1973 showed a better state of health than the German participants. This "healthy-migrant-effect" can be demonstrated for all three morbidity indicators used in this study (restriction of daily activities due to poor health, chronic illness, disablement). After controlling for age, only the indicator "restriction of daily activities" reveals higher morbidity rates for migrants than for German participants in 1984. With increasing age morbidity also increased between 1984 and 1992, but the increase was more pronounced for migrants than for the German participants. The resulting reduction of the "healthy-migrant-effect" can be seen most clearly for the indicator "chronic illness".
