From: GABA selectively increases mucin-1 expression in isolated pig jejunum
GABA concentrations (medians and percentiles 25/75) in the digesta of various segments of the gastrointestinal tract. Digesta samples were taken immediately after slaughter, and GABA levels were determined by UHPLC-ESI-MS. a, b Columns that do not share a common letter are significantly different (P = 0.036); n = 6. The GABA content in pig feed extract (produced from 1 g feed in 3.5 ml ultrapure water) was 179.8 µM
