So this question asks you about the crude protein needed in a supplement to meet the animal's cp requirement.
00:09
So first of all, we know that 79 % of the diet is made of corn, flake corn grain.
00:18
So out of this corn grain, it contains 8 .1 % of crude protein.
00:26
So 70, that's right.
00:30
The cp from the grain is, the corn grain is, let's say corn grain, is the dry matter of corn grain multiplied by 8 .1%.
00:56
So this is 79 % multiplied by 8 .1%.
01:04
So the total is 6 .399 % of the coming out of corn grain.
01:20
Now the hay contains 12 .8 % crude protein and then hay is 12%.
01:25
So the crude protein from hay is the dry matter of hay, k, which is 12%, and multiply by the crude protein ratio, which is 12 .8%.
01:43
This is 1 .536%.
01:50
Then you add up, these are the total crude protein that is already in the diet...
