The utilization of absorbed nitrogen was increased by prolonging the preliminary period or supplementing the rations with DES. The replacement of urea nitrogen with crude biuret depressed the digestibility of organic matter and crude fiber and apparent digestibility of protein, but did not influence the percentage retention of absorbed nitrogen.  adiethylstilbestrol  aFeed supplements  aLambs  aSheep  aApparent digestibility1 aANDERSON, G.
