Amino Acid Composition of the Fetal Pig1
ABSTRACT Amino acid composition and accretion were determined in fetal pigs obtained from gilts by hysterectomy at d 40-114 of gestation. The whole homogenate of the fetal pig was used for analysis of dry matter, nitrogen and amino acids. Uterine uptake of amino acids was estimated at d 110-114 of gestation on the basis of uterine arteriovenous concentrations. Nitrogen and amino acid accretion in fetal pigs increased more rapidly with gestation than non-nitrogen dry matter. Amino acid nitrogen represented 83-88% of total nitrogen, and arginine was the ...
