Covering and Flaring Manure Storage Units as a Methane Mitigation Strategy for Small- to Midsize Dairy Operations in the United States

Abstract Covering manure storages and flaring the captured methane (cap-and-flare) offers a technically feasible mitigation pathway for small- and midsize dairies that has received limited attention relative to anaerobic digestion (AD). While AD systems are more economically feas...

Observational study of the microbiome of perforated abomasal ulcers in unweaned beef calves in Canada

In western Canada, perforating abomasal ulcers (AU) are generally diagnosed postmortem in beef calves up to 2 months of age. Certain microbes have been associated with AU, but the evidence is circumstantial. Thus, analyzing the abomasal microbiome in calves with and without AU ma...

Economic competitiveness of separated dairy manure solids as a phosphorus fertilizer substitute

Manure solid-liquid separation offers a potential pathway for redistributing nutrients from livestock-intensive, nutrient-surplus regions to cropland with fertilizer demand, but the competitiveness of separated manure products with synthetic phosphorus fertilizer depends on manur...

2′‐ Fucosyllactose attenuates estrogen‐deficiency‐associated bone loss and intestinal dysfunction in ovariectomized rats

Abstract BACKGROUND Postmenopausal osteoporosis (PMO), driven primarily by estrogen deficiency, is the most prevalent form of osteoporosis and a major global health burden. Estrogen deficiency disrupts gut microbial homeostasis, compromises intestinal barrier integrity and promot...

Postbiotic mechanisms of long-term fermented soybean foods in host immunometabolic regulation: a critical appraisal of evidence, contradictions, and precision nutrition perspectives

Traditionally made long-term fermented soybean (LTFS) foods, including doenjang, miso, ganjang, and douchi, are produced through months to years of fermentation under high-salinity conditions (12-20% NaCl), generating convergent postbiotic profiles comprising free amino acids, is...
