Step 1: Understanding the Concept:
Poultry species are monogastrics and are highly sensitive to natural anti-nutritional factors present in certain plant-derived feed components.
Step 3: Detailed Explanation:
Sal seed cake is characterized by a very high concentration of tannins (ranging from 10--12%).
Tannins are polyphenolic compounds that bind with proteins, reducing enzyme activity, hindering protein digestibility, and introducing a bitter taste that diminishes feed intake.
This makes sal seed cake unsuitable for feeding poultry, as it negatively affects growth, egg production, and feed efficiency.
Conversely, Til cake (sesame cake), groundnut cake, and soybean meal contain highly digestible protein profiles with minimal toxic or anti-nutritional components, making them suitable for poultry diets.
Step 4: Final Answer
Due to its high concentration of inhibitory tannins, sal seed cake is not suitable for feeding poultry.
