MEASURES OF FOOD ENERGY AND THEIR APPLICATIONS

  • The force that enables to sustain life activities is energy.
  • Various types of energy, such as chemical, electrical and mechanical, radiant can be converted from one form to the other.
  • The plants trap energy from sun to synthesize complex constituents (chemical energy) that are broken to yield energy for maintenance of life in the animal for performance of work /production.
  • Energy required for maintenance of life includes:
    • Mechanical energy for essential muscular activities like heart beat, respiration etc.,
    • Chemical energy like movement of dissolved substance against concentration gradient, synthesis of enzymes & hormones.
  • Energy required for performance of work / production includes:
    • Muscular work.
    • Milk production.
    • Growth.
    • Egg production.
    • Wool production.

 

 

  • Force that sustains life activity is energy.
