Final answer:
The crude fiber concentration of rice bran on a dry matter basis is 7.01%.
Step-by-step explanation:
To find the crude fiber concentration of rice bran on a dry matter basis, we need to consider the dry matter concentration of rice bran. Let's assume the dry matter concentration of rice bran is x%. Since the dry matter concentration of hominy is 93%, we know that the remaining percentage is water. So, the dry matter concentration of rice bran can be calculated as:
x% = 100% - 93% = 7%
Now, we can find the crude fiber concentration of rice bran on a dry matter basis. We know that the crude fiber concentration of hominy on an as-fed basis is 9.5%. The as-fed basis includes both the dry matter and the water content. So, we can use the following equation to find the crude fiber concentration of rice bran on a dry matter basis:
Crude fiber concentration of rice bran on a dry matter basis = (Crude fiber concentration of hominy on an as-fed basis / Dry matter concentration of hominy) * Dry matter concentration of rice bran
Let's substitute the values into the equation:
Crude fiber concentration of rice bran on a dry matter basis = (9.5% / 93%) * 7% = 0.0701 = 7.01%
