Guanidinoacetic acid enhances Tibetan sheep-meat quality through the gut-muscle axis: insights from metabolome-microbiome integration
{{output}}
This study evaluated whether dietary guanidinoacetic acid (GAA) was associated with meat quality, jejunal microbiota and muscle metabolomic profiles in Tibetan sheep. A total of 120 healthy, 2-month-old, weaned male Tibetan sheep (17.33 ± 0.21 kg) were alloca... ...
