Overview of the re‐evaluation of trace elements as nutritional feed additives in the European Union: characterization, safety, and efficacy

Journal of the Science of Food and Agriculture, EarlyView.
Abstract The re‐evaluation of feed additives in the European Union was outlined in the Regulation (EC) No 1831/2003. The primary objectives were to ensure safety and verify efficacy, as well as to update authorizations and phase out unsafe additives or those in which the industry expressed no interest.

Understanding natural variation in milk lipids: why parity and lactation stage matter for nutritional value

Journal of the Science of Food and Agriculture, EarlyView.
Abstract BACKGROUND Bovine milk is a major dietary source of lipids whose fatty acid (FA) profile shapes its nutritional and technological quality, yet its natural variation is commonly described using fixed days‐in‐milk windows that ignore individual peak‐yield timing and parity‐specific metabolism.

Manure Composting as a Strategy to Mitigate Antibiotic Resistance Dissemination in Agricultural Systems

Land Degradation &Development, EarlyView.
ABSTRACT Livestock manure is a valuable agricultural resource but may introduce antibiotic residues and antibiotic resistance genes (ARGs) into the environment. This review critically evaluates the fate of antibiotics and ARGs during manure composting and identifies the principal factors controlling their attenuation.
