Question

The toxic component Gossypol is usually present in

• A. Cotton seeds
• B. Soybeans
• C. Mustard seeds
• D. Ground nut seeds

Hint:

Plant Protein Toxins in Aquafeeds:
Cottonseed meal = GOSSYPOL.
Raw Soybean meal = TRYPSIN INHIBITORS.
Mustard oil cake = GLUCOSINOLATES.
Groundnut cake = AFLATOXINS.

Answer 1

The Correct Option is A

Step 1: Understanding the Concept:
Feed toxicology and plant antinutritional factors: cottonseed meal contains the toxic polyphenolic pigment gossypol, which binds essential amino acids and damages intestinal membranes in aquaculture diets.

Step 2: Detailed Explanation:
Antinutritional factors in aquafeed plant protein ingredients:
1. Cotton Seeds (Cottonseed Meal) (A): Contains Gossypol (a toxic polyphenolic yellow pigment that inhibits digestive enzymes, causes liver damage, and binds dietary lysine).
2. Soybeans: Trypsin inhibitors and lectins (phytohemagglutinins).
3. Mustard Seeds: Glucosinolates (allyl isothiocyanates) and erucic acid.
4. Groundnut Seeds: Aflatoxins (from Aspergillus fungal contamination).

Step 3: Final Answer:
Thus, Gossypol is present in Cotton seeds, matching option (A).
