Whole-crop cereals in dairy production [PDF]

open access: yes, 2008
The four studies summarised and discussed in this thesis evaluate the use of whole-crop cereal silage (WCCS) for cattle in dairy production. The dry matter (DM) yield, chemical composition, digestibility, feed intake and milk production for WCCS were ...

β‐Catenin/c‐Myc Axis Modulates Autophagy Response to Different Ammonia Concentrations

open access: yesAdvanced Biology, Volume 9, Issue 3, March 2025.
Ammonia, detoxified by the liver into urea and glutamine, impacts autophagy differently at varying levels. Low ammonia activates autophagy via c‐Myc and β‐catenin, while high levels suppress it. Using Huh7 cells and Spf‐ash mice, c‐Myc's role in cytoprotective autophagy is revealed, offering insights into hyperammonemia and potential therapeutic ...

High‐Temperature Phase Transformation in a V‐9Si‐6.5B Alloy: The Kinetic and Crystallographic Pathway From V5SiB2 to V8SiB4

open access: yesAdvanced Engineering Materials, EarlyView.
In situ synchrotron high‐energy X‐ray diffraction reveals the real‐time high‐temperature phase evolution of a ternary V‐9Si‐6.5B alloy. The study uncovers a kinetically delayed V5SiB2 → V8SiB4 transformation governed by massive structural and chemical barriers.

Gradient‐Conductivity Architecture Enables Synchronous Enhancement of Sensitivity and Detection Range in Multifunctional All‐Paper Sensors

open access: yesAdvanced Functional Materials, EarlyView.
A gradient‐engineered all‐paper sensor is fabricated by integrating MXene and in situ grown AgNPs within hierarchical cellulose networks. The device breaks the sensitivity–detection range trade‐off through cascaded conductive pathways, enabling ultrahigh pressure sensitivity, humidity–pressure decoupled dual‐mode sensing, and outstanding EMI shielding,

Quantifying Economic Losses due to Milk Fever in Dairy Farms [PDF]

open access: yes
Milk fever, a metabolic disease, affects dairy animals usually within one or two days after calving, resulting in a huge reduction in milk production and thus becomes economically most important.

Multi-trait covariance functions to estimate genetic correlations between milk yield, dry matter intake and live weight during lactation

open access: yes, 1999
Energy balance is a function of dry-matter intake (DMI), live weight and milk yield over a certain time period. To investigate potential strategies to use genetic selection for the improvement of the negative energy balance, genetic co-variances were ...

Myogenic Fusogen‐Engineered Lipid Nanoparticles Enhance mRNA Delivery in Skeletal Muscle

open access: yesAdvanced Functional Materials, EarlyView.
This study reports a biomimetic strategy of engineering full‐length Myomaker, a muscle‐specific fusogen, into lipid nanoparticles (LNPs) to harness the native myoblast fusion capability for skeletal muscle mRNA delivery. The resulting Mymk‐LNPs enhance transfection in differentiating myocytes and enable Cre‐mediated reporter activation in injured ...

Effects of calf sex, breed and parity on the lactation performance of dairy cows in Trinidad and Tobago

open access: yesDiscover Agriculture
Dairy farming is important for food and nutrition security and livelihood protection in most tropical countries. However, productivity of dairy cows is affected by many factors and is usually low on smallholder farms in tropical environments.
