Energy Systems Matched with Scientists

Correct Answer: 1-d, 2-c, 3-b, 4-e, 5-a

Each energy system is associated with a specific scientist:

• Kellner (d): Developed the Starch Equivalent System in 1907. Based on Net Energy (NE) & Digestible True Protein. 1 Kg TDN = 0.86 Starch Equivalent.
• Atwater (c): Developed Physiological Fuel Value (PFV) — portion of gross energy available for transformation in the body. PFV of Carbohydrate = 4 kcal/g, Fat = 9 kcal/g, Protein = 4 kcal/g.
• Thaer (b): Developed Hay Equivalent System in 1810. Used meadow hay as a reference unit to compare all other feeds.
• Morrison (e): Developed the DCP, TDN & DM system — also known as the Modified Wolf-Lehmann Standard. Commonly used in Indian livestock. Published in 1915 in his book 'Feeds & Feeding'.
• Armsby (a): Developed the NE & True Protein system. Published 'Manual of Cattle Feeding'. His system is a productive-type feeding standard.
