Knowing that urea contains 45% n, one hundred lbs. of urea is the crude protein equivalent of how many pounds of soybean meal (44% cp)?

Knowing that urea contains 45% N, one hundred lbs. of urea is the crude proteinequivalent of how many pounds of soybean meal (44% CP)?SOLUTION:% Crude protein in urea = 45%N x 6.25=281.25Pounds of CP in 100 lbs. of urea = 2.8125 x 100 = 281.25CP equivalent of soybean meal = 281.25/0.44 = 639.20 lbs. (answer)2. An animal has the following dietary requirements: 20.0% CP; 1.0% Calcium;5.0% CF; and 1,200 Kcal/lb.If barley is contributing 8.0% CP, 0.2% Calcium,2.0% CF, and 850 Kcal/lb. to the diet, what percent of the animal’s dietaryrequirements are being met by barley?SOLUTIONCP, %8 / 20 x 100 =40Calcium, % 0.2 / 1.0 x 100 =20CF, %2 / 5 x 100 =40Cal/lb., %850 / 1,200 x 100 =70.83. A metric ton of mixed feed contains 250 kg of soybean meal, 700 kg of corn and50 kg of commercial basemix.What percent of the mixed feed is soybean meal,

The correct answer would be b
