Prevalence of, and risk factors associated with, perinatal calf mortality in pasture-based Holstein-Friesian cows [PDF]
, 2008 peer-reviewedRecent publications indicate that the prevalence of perinatal mortality has increased in some dairy industries and an increased proportion of this loss is not associated with the traditional risk factors for perinatal mortality.

mSystems, 2021 Dairy cows respond individually to stressful situations, even under similar feeding and housing conditions. The phenotypic responsiveness might trace back to their microbiome and its interactions with the host.

Insemination factors affecting the conception rate in seasonal calving Holstein-Friesian cows [PDF]
, 2003 peer-reviewedDifferences in conception rate to first service between artificial inseminations (AI) carried out by commercial AI operators (CAI) or do-it-yourself operators (DIY), between natural service (NAT) and AI, between different AI sires, and ...

The Journal of Reproduction and DevelopmentRetained placenta (RP) adversely affects postpartum productivity and reproduction in dairy cattle. Thus, methods to predict the occurrence of RP before calving would be desirable.

Empirical and theoretical considerations toward a model for caribou socioecology
Rangifer, 1986 The Delta and Yanert caribou (Rangifer tarandus granti) herds apparently maintained discrete calving areas from 1979 through 1983 (as determined by radio telemetry studies), even though substantial intermixing occurred during other seasons.

'Calving laws', 'sliding laws' and the stability of tidewater glaciers [PDF]
, 2007 A new calving criterion is introduced, which predicts calving where the depth of surface crevasses equals ice height above sea level. Crevasse depth is calculated from strain rates, and terminus position and calving rate are therefore functions of ice ...

Neurophysiology of Milk Ejection and Prestimulation in Dairy Buffaloes
Animals, 2022 The present review aims to integrate the anatomical characteristics of the mammary gland and the neurophysiology of milk ejection to understand the milking capacity of the water buffalo. Since one of the main uses of this species is milk production, this

Cow, farm, and herd management factors in the dry period associated with raised somatic cell counts in early lactation [PDF]
, 2008 This study investigated cow characteristics, farm facilities, and herd management strategies during the dry period to examine their joint influence on somatic cell counts (SCC) in early lactation.

A particle based simulation model for glacier dynamics [PDF]
, 2013 A particle-based computer simulation model was developed for investigating the dynamics of glaciers. In the model, large ice bodies are made of discrete elastic particles which are bound together by massless elastic beams.
