Fetal sex influence in the productive performance of dairy cows

Semina: Ciências Agrárias, 2016
Investigating factors that could affect milk production of cows is an important way to improve the efficiency of production systems. This purpose of this study was to verify and quantify the influence of calf sex on milk production and lactation length ...

Longitudinal study of calf morbidity and mortality on smallholder farms in southern Ethiopia.

PLoS ONE, 2021
Calf morbidity and mortality are serious constraints in the success of dairy calf production. Thus, the current study was carried out with the objective to estimate the incidence of calf morbidity and mortality and associated risk factors in milk-shed ...

Genetically Programmed Shape‐Morphing of Engineered Living Materials

Advanced Functional Materials, EarlyView.
Here, bacterial and mammalian engineered living materials (ELMs) are presented, in which living cells direct genetically programmed and enzymatically mediated shape‐morphing. The resulting deformation and shape‐recovery can be actuated in a genetically controlled manner by an ELM incorporating out‐of‐equilibrium counteracting biochemical reactions with

Comparative Assessment of Egg Quality Across Farming Systems and Stages of Laying Cycle

Applied Sciences
The aim of this study was the evaluation of egg quality between three different farming systems. Eggs collected from intensive (IS), extensive (ES), and dual-purpose systems (DPSs) at three stages of the production cycle (age) were analyzed for both ...

The Economics and Productivity of US Cow-Calf Production

Journal of Applied Farm Economics
We explore US beef cow-calf production in 2018 and estimate net returns, returns to scale, and technical efficiency associated with backgrounding versus nonbackgrounding by size and production system. We determine the relative profitability of cow-calf operations by type, region, and size. Results, using both stochastic production frontier analysis and

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.

Trends and factors associated with dairy calf early slaughter in Ireland, 2018–2022

Frontiers in Veterinary Science, 2023
Dairy systems require that each cow calves annually to have an efficient milk production cycle. In systems where milk production is maximized, the male offspring from dairy breed sires tend to have poor beef production traits and, therefore, can be of ...

Hybrid Biofabrication of a Hierarchically Organized Periosteum‐Inspired In Vitro Platform

Advanced Healthcare Materials, EarlyView.
A hybrid biofabrication strategy integrates melt electrowriting with extrusion‐based 3D bioprinting to create a hierarchically organized periosteum‐inspired in vitro platform. Spatially defined osteogenic, fibrous, and endothelial cell‐containing compartments support long‐term culture, osteogenic maturation, and CD31+ endothelial cell organization ...
