“…B 0 AT, also known as SLC6A19, is a sodium-dependent neutral amino acid transporter found in the jejunum of chickens. It transports various neutral (noncharged) amino acids such as leucine, isoleucine, valine, methionine, phenylalanine, and tryptophan ( Bröer, 2009 ; Stevens, 2010 ; Wong, 2022 ). B 0 AT transporters have a broad substrate specificity for neutral amino acids and play a vital role in the absorption of these amino acids in the jejunum ( Stevens, 2010 ).…”
