Detection of cefotaxime- and enrofloxacin-resistant and mcr-1-positive Escherichia coli at farm level in younger and older calf groups across different production systems in Germany [PDF]
BMC MicrobiologyObjective Studies on antibiotic resistance in calves rarely differentiate between production systems or younger and older calf groups within farms and commonly rely on non-selective laboratory methods. We investigated the qualitative farm-level detection

Methods for estimating milk production of dairy cows with full cow-calf contact [PDF]
JDS CommunicationsDairy cows with full cow-calf contact can nurse their calves and perform maternal behaviors without hindrance. Owing to the unrestricted suckling, the total milk production of the suckled cows (i.e., machine milk yield [MMY] and milk consumed by the calf)

Calving of the experimental reindeer herd in Kaamanen during 1970 - 85
Rangifer, 1986 Calving and calf production were studied in an experimental reindeer (Rangifer tarandus L) herd in Inari, Kaamanen (69°10'N) in northern Finland. Most of the calving took place between May 10 and 29; 50% of the calves were born up to 22.5.
