Study links coated betaine to better lamb meat quality

A new study in Animals reports that adding 0.20% coated betaine, a rumen-protected methyl donor, to lamb diets for 60 days improved several meat-quality and flavor-related measures in Dorset × Hu crossbred lambs. The trial included 18 lambs split between a basal diet and the coated betaine diet. According to the paper, coated betaine improved traits tied to eating quality and was associated with shifts in rumen fermentation and microbial composition, supporting the authors’ conclusion that the additive may influence meat flavor through the rumen microbiome. The paper was published March 20, 2026, and builds on earlier work showing rumen-protected betaine can increase flavor amino acids and improve some meat-quality traits in growing lambs.

Why it matters: For veterinary professionals working with sheep producers, the study adds to a growing body of evidence that rumen-targeted nutrition can affect not just performance, but carcass value and consumer-facing meat characteristics. That’s relevant in systems where producers are looking for feed additives that may improve product quality without relying on drug-based interventions. Still, this was a small study in one crossbred lamb population, published in an open-access journal, so field applicability, cost effectiveness, and reproducibility under commercial conditions remain important open questions.

What to watch: Watch for follow-up trials in larger commercial flocks, dose comparisons, and any independent validation tying coated betaine to consistent carcass premiums or sensory gains. (deepdyve.com)
