Question

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)?

Answer 1

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,
