Now use the upper value at ur right hand side which is 37.7 to divide 69.25 times 99… That’s 37.7/69.35 *100 = 53.89kg of protein feedstuff materials will be needed for the formulation.
Now use the lower value at ur right hand side which is 31.55 to divide 69.25 times 99… That’s 31.55/69.25 * 99 = 45.10kg of energy feedstuff materials will be needed for the formulation.
Formulation is in 100kg but will are using 99kg cause we minus Inclusion total which is 1kg from 100kg to be 99kg.
