BACKGROUNDBACKGROUND
In animal production, feed has important role.Feed cost is as major variable cost (60-80%) in animal production.Therefore, the ration formulation is very important as major contribution on farmer’s profit. To formulate a Least Cost Ration needTo formulate a Least-Cost Ration need computer to running a ration formulation program.

Formulate a ration (CP 20%) from Soybean Meal (SBM) and Corn
SBM (45%) 10 Unit(10/35)= 28.6%

Corn (10%) 25 Unit(25/35)= 71.4%

Simultaneous Equ. MethodSimultaneous Equ. Method
Use mathematical equationsIf X = used corn and Y = used SBM, then the nutrientrequirement can be calculate with this equation 1818 == 00..1010XX++ 00..4545YY;; and if X + Y = 100, then both equations can beused to calculate the level of X and Y.
0.10X + 0.45Y = 20- 0.10X + 0.10Y = 10 from (X + Y = 100)/0.10
0 + 0.35Y = 100 0.35Y 10then Y = (10/0.35) = 28.6%; SBM = 28.6%
X = 100 – 28.6 = 71.4%; Corn = 71.4%

Linear Programming
Linear Programming (LP) is a technique for ea og a g ( ) s a ec que ooptimization of a linear objective function, subject to linear equality and linear inequality constraints. Informally LP determines the way to achieve the best outcome (such as maximum profit or lowest cost)Developed by George B Dantzing publishedDeveloped by George B. Dantzing, published the simplex method in 1947
