R.  aUrea and stilbestrol for fattening lambs.  c1956  aResults from a factorial experiment involving 72 Columbia-type lambs on two different protein supplements and four levels of stilbestrol are presented. Soybean oil meal was a significantly better protein supplement than urea when urea (42% N) was fed at the rate of three % of the concentrate mixture with poor quality non-legume hay (urea furnished 41% of the nitrogen in the ration). Feeding stilbestrol produced significantly greater gains on both types of nitrogen. There were no significant differences in carcass grades or yields as a result of stilbestrol treatment. No death loss nor observable deleterious effects were attributable to the stilbestrol.  aAnimal feeding  aAnimal nutrition  aFeed supplements  aProtein concentrates  aSheep  aUrea  aFattening  aStilbestrol1 aDINUSSON, W.
