Scientist Who Developed the Starch Equivalent Energy System

Correct Answer: Kellner

Kellner developed the Starch Equivalent (SE) System in 1907. It is a productive-type feeding standard based on Net Energy (NE) and Digestible True Protein.

Kellner's Starch Equivalent System

• Reference standard = pure starch
• 1 Kg TDN = 0.86 Starch Equivalent (SE)
• The SE value of a feed is the amount of starch that produces an equivalent amount of body fat as 100 kg of that feed
