Shedding patterns of dairy calves experimentally infected with Mycobacterium avium subspecies paratuberculosis
TL;DR: Calves inoculated up to 1 year of age shed MAP in their feces shortly after inoculation, meaning there is potential for MAP transfer between calves (especially if they are group housed) and therefore, JD control programs should consider young calves as a source of infection.
Host defense cathelicidins in cattle: types, production, bioactive functions and potential therapeutic and diagnostic applications.
TL;DR: Comparison of the structural, antimicrobial, cytotoxic and mechanistic properties of bovine cathelicidins advances the knowledge needed for the development of these peptides as potential identifiers of infectious diseases and as novel therapeutic alternatives to antibiotics.

TL;DR: The results indicate that the developed English and French questionnaires can be used simultaneously to accurately measure the udder health related management practices used on Canadian dairy farms and is adaptable for use in other developed dairy industry populations.

Association of standing and lying behavior patterns and incidence of intramammary infection in dairy cows milked with an automatic milking system
TL;DR: Standing and lying behavior patterns of cows milked with an AMS were affected by both feed manipulation and their milking activity, and cows that spend long periods of time standing following milking may be at higher risk of acquiring a new CNS IMI.

Prevalence and molecular characterization of Cryptosporidium spp. in dairy calves from 11 farms in Prince Edward Island, Canada
Tatjana Coklin,Fabienne D Uehlinger,Jeffrey M. Farber,Herman W. Barkema,Herman W. Barkema,Ryan O’Handley,Ryan O’Handley,Brent R. Dixon +7 more
TL;DR: DNA sequence analysis on five PCR positive samples demonstrated that Cryptosporidium parvum was the only species present in the calves tested, suggesting that there is a potential risk of zoonotic transmission between dairy calves and humans in this region.
