Answer:
To make a 1 ton ration of an 18% protein ration using corn (12%) and soybean meal (22%), 0.6 tons of soybean meal and 0.4 tons of corn are needed
Explanation:
Using the Pearson’s Square calculations:
1. Subtract across the diagonal:
a. 18% - 12% = 6 parts soybean meal
b. 18% - 22% = 4 parts corn
2. Sum the parts:
a. 6 parts soybean meal + 4 parts corn = 10 totalparts
3. Divide each part by the total to calculate the percentage of each feed to include in the ration:
a. 6 parts soybean meal ÷ 10 total parts * 100 = 60.0% soybean meal
b. 4 parts corn ÷ 10 total parts * 100 = 40.0% corn
So, to make 1 ton ration of an 18% protein ration using corn (12%) and soybean meal (22%),
60% of soybean meal is needed = 60/100 * 1 ton = 0.6 tons of soybean meal
40% of corn is needed = 40/100 * 1 ton = 0.4 tons of corn
