• B. A ‐ I, B ‐ IV, C ‐ II, D ‐ III

Hint:

To safely feed cottonseed cake to non-ruminants, add iron salts (such as ferrous sulfate) to the ration. Iron binds free gossypol and prevents its absorption in the gut.

Answer 1

The Correct Option is A

Step 1: Understanding the Concept:
Unconventional feed ingredients are alternative feed resources that can supplement standard rations.
However, many of these ingredients contain specific anti-nutritional factors (ANFs) or toxins that must be identified and inactivated to ensure animal safety and production performance.

Step 2: Detailed Explanation:
Let us match each unconventional feed ingredient with its corresponding anti-nutritional or toxic factor:
- A. Castor seed meal: Derived from Ricinus communis, it contains a highly toxic glycoprotein called Ricin, which inhibits protein synthesis inside cells (A - IV).
- B. Cottonseed cake: Contains a polyphenolic pigment called Gossypol, which causes cardiac toxicity, erythrocyte fragility, and reproductive impairment in non-ruminants (B - III).
- C. Tamarind seed hulls: Rich in polyphenolic compounds known as Tannins, which bind dietary proteins and digestive enzymes, reducing protein digestibility (C - I).
- D. Mahua seed cake: Obtained from Madhuca longifolia, it contains a toxic saponin called Mowrin, which has a bitter taste and causes hemolysis of red blood cells (D - II).
This matching corresponds to the sequence: A - IV, B - III, C - I, D - II.

Step 3: Final Answer:
The correct matching of feed ingredients to their anti-nutritional factors is A - IV, B - III, C - I, D - II.
