[Comparison of the digestive utilization of methionine, of its hydroxylated analog, and of sodium sulfate in goats using 35s compounds].
35S and 35S free and protein bound amino acids were estimated in goats' abomasal contents and blood after ruminal injections of sulfer labelled compounds: methionine, methionine hydroxy analog (M.H.A.) and sodium sulfate. 35S incorporation into microbial and plasma proteins was higher with methionine than with M.H.A. or sulfate. 35S.M.H.A. utilisation seems to be less different from Na2 35SO4 utilisation than from 35S methionine utilisation.
