Answer
The correct classification for a farm animal with a simple stomach system is B. non-ruminant. Non-ruminant animals have a single-chambered stomach, unlike ruminants which have a multi-chambered stomach.

Answer
The appropriate term for measuring the protein content is A. nutritive ratio. It provides insight into the availability of proteins and nutrients in a feed.
Step 3
1.1.3 A ration is made up of two feeds (Feed A and Feed B) mixed to get a total digestible protein (DP) content of 40 kg of Feed A, with a DP value of 9%. The digestible protein (DP) content for Feed B is …

Answer
To calculate the digestible protein content for Feed B, we can set up the equation as follows:
Given:
Total DP from Feed A = 40 kg * 0.09 = 3.6 kg
Assuming the total DP required is X for the mixture:
We can use the formula where total DP = DP from Feed A + DP from Feed B. Therefore, we need to know DP from Feed B.
If we work backwards using the given options, we find that with:
B. 15%, we find it suitable as it would provide sufficient protein.
