Worked Solution & Example Answer:Classification of animals DIAGRAM A - Ruminant/polygastric DIAGRAM B - Non-ruminant/monogastric TWO adaptation features of animal in DIAGRAM A 1 - NSC Agricultural Sciences - Question 2 - 2019 - Paper 1
Step 1
Classification of animals
Answer
In Diagram A, the animal is classified as a ruminant or polygastric, which is characterized by a complex stomach structure that allows for fermentation and digestion of cellulose-rich feeds. In Diagram B, the animal is classified as non-ruminant or monogastric, indicating it has a simpler stomach structure.
Step 2
TWO adaptation features of animal in DIAGRAM A
Answer
- The animal has a complex stomach structure (polygastric) that allows efficient fermentation of fibrous feeds, facilitating better nutrient absorption.
- It possesses a large fermentation vessel, the rumen, where microbial activity breaks down complex carbohydrates.
Step 3
Reason for not feeding animal in DIAGRAM B with a ration high in crude fibre content
Answer
The animal in Diagram B should not be fed a high crude fiber ration because it has a monogastric/simple stomach, making it less capable of digesting fibrous materials. Additionally, the absence of necessary microflora limits its ability to break down such high-fiber feeds.
Step 4
Explanation on how animal in DIAGRAM A benefits from non-protein nitrogenous substance
Answer
The animal uses non-protein nitrogenous substances like urea, which are converted into ammonia by urease. This ammonia is then utilized by microorganisms in the rumen to produce microbial protein, enhancing the nutritional quality of the feed.
