Match the column:
| Table A (System) | Table B (Scientist) |
|---|---|
| 1. Starch equivalent system | (a) Armsby |
| 2. Physiological fuel value | (b) Thaer |
| 3. Hay equivalent system | (c) Atwater |
| 4. DCP, TDN & DM system | (d) Kellner |
| 5. NE & True protein system | (e) Morrison |
- 1-d, 2-c, 3-b, 4-e, 5-a — Correct Answer
- 1-b, 2-c, 3-a, 4-e, 5-d
- 1-d, 2-a, 3-b, 4-e, 5-c
- 1-c, 2-d, 3-b, 4-a, 5-e
Explanation:
Correct Answer: 1-d, 2-c, 3-b, 4-e, 5-a
These are the five foundational feeding standard systems in animal nutrition, each associated with its developer.
Matching — Feeding Systems and Scientists
| System | Scientist | Basis |
|---|---|---|
| 1. Starch Equivalent System | (d) Kellner | Net Energy & Digestible True Protein; published 1907 |
| 2. Physiological Fuel Value | (c) Atwater | PFV = GE × Digestibility coefficient |
| 3. Hay Equivalent System | (b) Thaer | Published 1810; meadow hay used as comparative unit |
| 4. DCP, TDN & DM System | (e) Morrison | Modified Wolf-Lehmann standard; most common in Indian livestock |
| 5. NE & True Protein System | (a) Armsby | Based on Net Energy; published "Manual of Cattle Feeding" |
Key Extra Facts
- Grouven formulated the first feeding standard in 1859 (protein, fat & carbohydrate)
- Morrison's standard published in 1915 in "Feeds & Feeding"; commonly used in India
- ICAR feeding standard given by Dr. S.K. Ranjhan
- ARC standard: UK standard (1959), now replaced by AFRC
- NRC standard: USA standard (1945)
Why Other Options Are Wrong
- Option 1-b, 2-c, 3-a, 4-e, 5-d → swaps Thaer and Kellner; Thaer gave Hay Equivalent, not Starch Equivalent
- Option 1-d, 2-a, 3-b, 4-e, 5-c → puts Morrison in Physiological Fuel Value — incorrect; Atwater gave PFV
- Option 1-c, 2-d, 3-b, 4-a, 5-e → completely wrong pairing for Kellner, Atwater, and Morrison
