1 Formulate 500 lbs of a 21% cp ration using soybean meal( 44% cp) and corn (9% cp)
How many pounds of soybean meal will be used?
12 parts soy bean meal/ 35 parts total = 0.34 parts from soy bean meal
0.34 parts from soy bean meal X 500 lbs ration = 170 lbs soy bean meal
How many pounds of corn will be used ?
23 parts corn / 35 parts total = 0.66 parts from corn
0.66 parts from corn x 500 lbs ration = 330 lbs corn needed
