Definition of Protein Supplements
Protein supplement contains:
- Less than 18% crude protein and more than 20% crude fiber
- More than 20% Crude protein and less than 18% crude fiber — Correct Answer
- Less than 20% crude protein and less than 18% crude fiber
- More than 20% Crude protein and More than 18% crude fiber
Explanation:
Correct Answer: More than 20% Crude Protein and less than 18% Crude Fibre
Protein supplements are defined as feedstuffs containing more than 20% Crude Protein (CP) and less than 18% Crude Fibre (CF). They are distinct from energy feeds (which have CP <20%) and roughage (which has CF >18%).
Feed Classification Summary
| Feed Type | CP % | CF % | Examples |
|---|---|---|---|
| Roughage | Variable | >18% | Straw, hay, silage |
| Basal/Energy feed | <20% | <18% | Cereal grains, brans, molasses |
| Protein supplement | >20% | <18% | GNC, soybean meal, fish meal, blood meal |
Protein Supplement — Examples
- Plant origin: GNC (DCP ~45%), Soybean meal, Cotton seed cake, Sunflower cake, Rapeseed cake, Yeast
- Animal origin: Fish meal, Meat meal, Feather meal, Blood meal
Why Other Options Are Wrong
- Less than 18% CP and more than 20% CF → describes rough, low-quality forage; not a protein supplement
- Less than 20% CP and less than 18% CF → describes basal/energy feed
- More than 20% CP and more than 18% CF → contradictory; a high-fibre, high-protein feed doesn't qualify as a concentrate protein supplement
