Polyethylene glycol reduces the net flux of
branched-chain amino acids across the mammary
gland in ewes fed sulla

Six lactating ewes were orally drenched each day with polyethylene glycol to remove the effects of the condensed tannins in sulla (Hedysarum coronarium) and six other ewes (control) received a drench of water. The treatments were started 28 days prior to the measurement period. At week 6 of lactation, net absorption of branched-chain amino acids in the mesenteric vein was not affected by PEG. Valine and leucine were released by the liver in the PEG ewes and extracted in the control ewes. The net mammary uptake of isoleucine and leucine was lower in the PEG ewes.
