TI  - Effect of soybean lipid on growth and ruminal nitrogen metabolism in cattle fed 
      soybean meal or ground whole soybeans.
PG  - 1680-9
AB  - Three experiments were conducted to determine the effect of soybean lipid on 
      ruminal proteolysis of soybean meal (SBM) and ground whole soybeans (GSB). 
      Experiment 1 was a 92-d growth experiment using 120 calves (206 kg) allotted to 
      12 pens of 10 calves each. Three replicate pens were assigned to each of the 
      treatment supplements: low SBM (LSBM), low GSB (LGSB), high SBM (HSBM) and high 
      GSB (HGSB). Calves received ad libitum amounts of corn silage top-dressed with 
      the respective supplement (.81 kg/head). High protein supplements produced 
      greater (P less than .05) gains than low protein supplements, with HSBM calves 
      gaining faster (P less than .05) than HGSB calves and LSBM and LGSB calves having 
      similar (P greater than .10) gains. In Exp. 2, 15 ruminally cannulated Angus X 
      Hereford heifers (380 kg) fed corn silage were used to determine ammonia-N 
      release from the treatment supplements: ground corn (control), GSB, SBM and SBM 
      coated with soybean oil (SBMO). Heifers fed the control supplement had lower (P 
      less than .05) ruminal NH3-N concentrations than those consuming soybean protein. 
      Ruminal NH3-N concentrations were similar (P greater than .10) for GSB and SBM; 
      whereas, SBMO had lower (P less than .10) concentrations than SBM through 3 h. In 
      Exp. 3, two ruminally cannulated Angus X Jersey steers (250 kg) were used to 
      determine in situ disappearance of SBM, GSB and SBMO. Total and feed N 
      disappearances were greater (P less than .001) for GSB than SBM or SBMO.(ABSTRACT
