Abstract

This study investigated the potential effects of management and health related factors on the productivity in the commercial mink production, during 2015-2018. Data were available from the database at Kopenhagen Fur, the national veterinary prescription database, VetStat, and the laboratory database at the Center for Diagnostics, Technological University of Denmark. A cross-sectional study, including 1.464 min. farms grouped into 1.187 epidemiological units, was applied. Data were analyzed in two models with different outcomes representing productivity on the mink farms, namely skin size and economical value (value sum) of the produced skin. The studied risk factors included use of vaccines and antibacterials, herd size, associated feed producer, purchases and sales of live animals, breeding results (litter size after weaning), Aleutian mink disease virus antibody (AMDV status) and stamping out, and laboratory test results.

Vaccination against mink enteritis parvovirus and high breeding results were found to have a positive association with both outcomes, skin size and value sum. Both outcomes also varied significantly between farm clusters associated with different feed producers. Significant effects of antibacterial treatment were found, but the results were complex with both positive and negative associations with the outcome variables, depending on season and interactions with feed producer. Positive effects on antibacterial prescription on skin size were observed, except for farms associated with two small feed producers, known to have a variable microbiological feed quality. In farms receiving feed of very high quality, the positive effect of antibacterial prescription was marginal.
