The Influence of Synthetic Analogues of PgF2 on the Evolution of Puerperal Period and the Duration of the Interval from Calving to the First Estrus in Cows

Scientific Papers Animal Science and Biotechnologies, 2023
Puerperal period is the most critical period from the productive life of females, at the borderline between physiologic and pathologic. In this stage some reproductive turbulence may appear (uterine subinvolution, uterine infections, ovary inactivity ...

Parturition intervals and distributions of parturitions by months of buffalo in Southern and South-eastern Brazil

Italian Journal of Animal Science, 2010
Reproductive rate is an important component of economic success in livestock production. Parturition interval (IEP) is a direct measure of the productivity of the animal. Long IEP reduce the number of calves produced per year.

Genetic evaluation of fertility using direct and correlated traits [PDF]

, 2003
Poor fertility has become a major reason for involuntary culling of dairy cows in the United Kingdom. Calving interval (CI) and body condition score (BCS) are recorded, heritable, genetically correlated with each other, and could be used to extend the ...

'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 ...

NeuroVisio SyncPatch: A Skin‐Conformal Multimodal EMG–Motion Sensing Platform for Quantitative Neuromuscular Rehabilitation and Performance Monitoring

Advanced Healthcare Materials, EarlyView.
NeuroVisio SyncPatch integrates skin‐conformal electromyography (EMG) electrodes with camera‐tracked markers to jointly assess muscle activity and three‐dimensional knee kinematics during rehabilitation. Parallel feedback pathways provide real‐time kinematic guidance during movement and post‐trial neuromuscular feedback.
