  • Animal nutrition includes nutrient requirement, mode of intake of food and its utilization in the body.
  • Each and every animal requires food for energy to perform various activities like running, walking, jumping, reading etc.
  • This energy is obtained from the food they eat. In order to obtain energy, the food that they eat need to be digested and then assimilated.

Digestion is the process of breakdown of complex components of food substances into simpler form.
