Formulate a supplement for cattle so that it contains 41 cru

Formulate a supplement for cattle so that it contains 41% crude protein (CP) on an as fed (AF) basis. Use soybean meal (45% CP, AF basis) and urea (286% CP, AF basis), and ground corn grain (9% CP, AF basis) as a carrier. To prevent the addition of too much urea (toxic amounts), lock in urea as a fixed ingredient at 10% of the supplement (AF basis). Also, 12% of the supplement as fed should be reserved for minerals (HINT: this is the MSE). What is the % soybean meal (AFB) needed in the supplement for it to contain 41% CP?

Solution

According to given data in question statement 10%of supplement will be urea, 12% reserved for minerals; remaining 78% we need to decide so that we get 41%cp by adding soyabean meal in our supplement constituents.

Now if we take 41% of 78 it comes out to be 32% approximately and this is what we require.
