4. Pearson Square Diet Balancing 26.4 parts Corn 9.1 parts SBM 35.5 Total parts 26.4/35.5 x 100 = 74.4% Corn 9.1/35.5 x 100 = 25.6% SBM

5. Pearson Square Diet Balancing 2,000 lb x 0.744 = 1,488 lb Corn 2,000 lb x 0.256 = 512 lb SBM Make a 1 ton batch of this swine feed

6. Pearson Square Diet Balancing Want to use 3 ingredients? Corn, barley, SBM Group similar feeds Corn + barley SBM

7. Pearson Square Diet Balancing Use a mixture of corn + barley as feed 1 Use SBM as feed 2 Mixture – 50:50 0.50 x 8.9% CP in corn = 4.45 0.50 x 13% CP in barley = 6.5 %CP of mixture = 4.45 + 6.5 = 10.95%
