Does the regulation of manure land application work against agglomeration economies? Theory and evidence from the French hog sector [PDF]

open access: yes
The well-known increase in the geographical concentration of hog production suggests the presence of agglomeration economies related to spatial spillovers and inter-dependencies among industries. In this paper, we examine whether the restrictions on land

MANURE VALUE AND LIVEWEIGHT SWINE DECISIONS [PDF]

open access: yes
Produced as a joint product, economic theory suggests that manure value could influence livestock management decisions such as herd size and optimal market weights. This study examines the concept of manure and its connection with optimal replacement age

Metagenomics and digital cell modeling facilitate targeted high‐throughput sorting of anaerobic hydrogen‐producing microorganisms

open access: yesiMeta, EarlyView.
This study proposes a novel strategy that prioritizes functional recognition, followed by targeted high‐throughput sorting, to enable the comprehensive, rapid, and efficient acquisition of target microorganisms. Using metagenomic sequencing and binning analysis, we identified 215 potential anaerobic hydrogen‐producing strains from 12 large‐scale biogas

Electrochemical detection of chloramphenicol in feed and soil matrices using SPCE‐N‐GQD sensors for on‐site screening applications

open access: yesJournal of the Chinese Chemical Society, EarlyView.
Nitrogen‐doped graphene quantum dots (N‐GQDs) were anchored onto screen‐printed carbon electrodes to selectively preconcentrate chloramphenicol (CAP). Enhanced electrochemical profiles and pH‐sensitive responses—highlight NGQD‐facilitated charge‐transfer behavior, reinforcing its potential in CAP monitoring within livestock feed and broader ...
