Effects of feeding almond hulls to light lambs on carcass characteristics and meat quality

Journal of the Science of Food and Agriculture, Volume 106, Issue 6, Page 3876-3884, April 2026.
Abstract BACKGROUND Almond hulls (AH) are the main by‐product of almond processing for human consumption and contain bioactive compounds that can improve meat quality. Although AH are used as feed for dairy cows in some countries, information on their potential effects on meat quality is limited.

Practical Applications of Secondary/Extractive Electrospray Ionization (SESI): A Versatile Tool for Real‐Time Chemical Analysis

Mass Spectrometry Reviews, Volume 45, Issue 2, Page 392-428, March/April 2026.
ABSTRACT In the 1980s, researchers discovered the remarkable ability of electrospray plumes to effectively ionize gas‐phase molecules via secondary ionization. Around 20 years later—coinciding with the ambient mass spectrometry revolution—secondary electrospray ionization (SESI) and extractive electrospray ionization (EESI) coupled to mass spectrometry

Early‐Life Respiratory Emissions of CO₂, CH₄, and N₂O in Pre‐Weaned Dairy‐Bred Calves

Journal of Sustainable Agriculture and Environment, Volume 5, Issue 1, March 2026.
ABSTRACT Greenhouse gas (GHG) emissions from livestock are a major contributor to climate change, with cattle known to be the principal contributor through enteric fermentation, manure management, and metabolic processes. This study investigates the emission rates of CO₂, CH₄, and N₂O in pre‐weaned calves aged 12 to 86 days, focusing on the ...
