Updating test-day milk yield factors for use in genetic evaluations and dairy production systems: a comprehensive review

open access: yesFrontiers in Genetics, 2023
Various methods have been proposed to estimate daily yield from partial yields, primarily to deal with unequal milking intervals. This paper offers an exhaustive review of daily milk yields, the foundation of lactation records.

On‐Chip Multiplexed Voltammetry Using a Universal Antifouling Hydrogel and Porous Gold Foam Interface for Stress and Inflammation Monitoring

open access: yesAdvanced Sensor Research, EarlyView.
A multiplexed device is fabricated via silicon microelectronics and adapted for electrochemical sensing interface. Its 100 um gold disk electrodes are modified with porous gold foam and coated with a rapid, biocompatibleantifouling layer. Universal immunoglobulin G (IgG) capture is enabled through Protein A/G.

Stacking Interventions Enhances Carbon Removals and Profitability of Livestock Production Systems

open access: yesAdvanced Science, EarlyView.
The study indicates that stacking multiple interventions aimed at maximising soil organic carbon (SOC) sequestration and enteric methane (CH4) reductions realizes greater abatement and profit do any singular intervention, especially when SOC sequestration accounts for a significant proportion of greenhouse gas emissions (GHG) mitigation.

Genomic Insights into the Origin, High Fecundity and Environmental Adaptation of Hu Sheep

open access: yesAdvanced Science, EarlyView.
The Hu sheep diverged from the Small‐tailed Han sheep ≈1330 years ago, and subsequently migrated from northern to warm and humid southern regions. The genes BMPR1B, UNC5C, and GRID2 play a synergistic role in the superior reproductive traits of Hu sheep.
