Acute puerperal metritis (APM) in dairy cows is often treated with antibiotics. An increasing antibiotic resistance is well documented and associated with decreasing clinical efficacy, animal welfare and economic consequences. Hence, there is a significant need to encourage prudent use of antibiotics and alternative therapies to antibiotics. The objective of this study was to compare the effica...

in lying time among odor treatments. HR piglets exposed to AA, NB or MF had decreased lying time compared with ISO. MR pigs spent more time PFF (interested in the odor) when exposed to MF or NB compared with ISO. LR pigs showed similar PFF when exposed to each odor. HR piglets showed more PFF when exposed to MF than ISO. MR piglets showed more PAF (avoided the odor) when exposed to MP and AA th...

Bovine respiratory disease complex (BRDC) is a multi-factor disease, and disease incidence may be associated with an animal’s commensal microbiota (metagenome). Therefore, evaluation of the animal’s resident microbiota in the upper nasal cavity may help us to understand the effect of the metagenome on incidence of BRDC in cattle. Nasal swabs from approximately 600 calves were collected at vario...
