Food Science &Nutrition, Volume 14, Issue 2, February 2026.Treating date palm leaves with a bacterial consortium, especially when supplemented with glucose and urea, significantly degrades lignin. This process enhances nutritional value by increasing crude protein, digestibility, and metabolizable energy. The method effectively transforms this agricultural by‐product into a viable ruminant feed.

Metabolism of soluble proteins by rumen microorganisms and the influence of condensed tannins on nitrogen solubility and degradation [PDF]
, 2004 The amino acid requirements of ruminants are met by two sources; microbes leaving the rumen and dietary protein escaping fermentation in the rumen. Much ruminant research has therefore focused on improving amino acid supply to the duodenum by increasing ...

Food Science &Nutrition, Volume 14, Issue 2, February 2026.Lycium barbarum byproducts (seeds and residue) in sheep diets increased acetic and propionic acid, digestive enzyme activity, and beneficial bacteria (Prevotella). Immune status (TP, ALB, GLB) and antioxidant capacity (SOD, GSH‐PX) improved, while waste metabolites (UA, BUN) and oxidative stress (MDA) decreased.

The role of the gut microbiome in the regulation of high‐altitude adaptation
iMeta, Volume 5, Issue 1, February 2026.This study is the first to elucidate mechanisms of high‐altitude adaptation from the perspective of the rumen ecosystem by using indigenous yaks and Holstein cows that have lived at high altitude since birth as comparative models. Through a systematic comparison of their rumen ecology using multi‐omics approaches—including rumen metagenomics ...

Effects of pH and Concentrations of Linoleic and Linolenic Acids on Extent and Intermediates of Ruminal Biohydrogenation in Vitro [PDF]
, 2003 Three experiments were conducted by in vitro incubations in ruminal fluid to investigate the effects of pH and amounts of linoleic and linolenic acids on the extent of their biohydrogenation, the proportions of conjugated linoleic acid (CLA) and trans ...
