The objective of this study was to identify the calf-level colostrum management practices associated with an adequate transfer of passive immunity (TPI; defined as serum Brix refractance ≥8.4% in the first week of life) in small-sized herds. A total of 818 calves from 61 commercial Holstein dairy farms were included in this observational cross-sectional study.

An observational cross-sectional study was conducted between October 2015 and February 2016.

- Wildlife reservoirs can complicate disease management, as seen with a recent outbreak of brucellosis in a French ibex population after cases emerged in cattle and humans.
- A study of 88 infected ibex revealed that 58% had active infections, with a notable prevalence in young females, potentially linked to their reproductive processes.
- The differences in shedding patterns between sexes and ages highlight the need for targeted management strategies to control the spread of brucellosis in wildlife populations.
Article Synopsis
- Understanding how animal ecology impacts disease spread is crucial, especially with wild ungulates that can share pathogens with domestic animals.
- For the first time in Europe, an outbreak of brucellosis in Alpine ibex was linked to transmission to cattle and humans, highlighting the importance of studying wildlife disease dynamics.
- The study found that female ibex were more spatially segregated than males, influencing the spread of the disease and suggesting that non-sexual transmission routes are significant for managing brucellosis in these populations.
