Microbiome Clusters Disclose Physiologic Variances in Dairy Cows Challenged by Calving and Lipopolysaccharides

open access: yesmSystems, 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.

Effect of restricting silage feeding prepartum on time of calving, dystocia and stillbirth in Holstein-Friesian cows

open access: yesIrish Veterinary Journal, 2007
A study was carried out to investigate the effect of restricting silage feeding on time of calving and calving performance in Holstein-Friesian cows. In the treatment group (n = 1,248 cows, 12 herds) silage feeding commenced in the evening (17:00 to 20 ...

Neurophysiology of Milk Ejection and Prestimulation in Dairy Buffaloes

open access: yesAnimals, 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

Glacial Ice‐Front Calving: Internal Wave Generation and Melting

open access: yesGeophysical Research Letters
Small, frequent calving events dominate the behavior of most Arctic marine‐terminating glaciers, yet their oceanographic impacts remain largely unquantified.

Association between prepartum vaginal temperature changes and placenta expulsion time in Holstein dairy cattle

open access: yesThe Journal of Reproduction and Development
Retained 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

open access: yesRangifer, 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.

Characteristics, recent evolution, and ongoing retreat of Hunt Fjord Ice Shelf, northern Greenland

open access: yesJournal of Glaciology, 2023
Arctic ice shelves have declined over the past several decades, one of many indications of a rapidly changing cryosphere. Here we use a collection of off-nadir Landsat 8 images, a 1978 digital orthophotograph and photogrammetrically derived DEM ...

Drivers of Recurring Seasonal Cycle of Glacier Calving Styles and Patterns

open access: yesFrontiers in Earth Science, 2021
Calving is a crucial process for the mass loss of outlet glaciers draining the Greenland ice sheet. Moreover, due to a lack of observations, calving contributes to large uncertainties in current glacier flow models and projections.

Causal analysis of trade loss from pathogens: A global study of foot and mouth disease impacts on meat exports

open access: yesAmerican Journal of Agricultural Economics, EarlyView.
Abstract Our general interest is in global trade loss from livestock pathogens, specifically exports. We adopt a causal inference approach that considers animal disease outbreaks over time as non‐staggered binary treatments with the potential for switching in (infection) and out of treatment (recovery) within the sample period. The outcome evolution of
