50-95 percent
functions of water
° essential constituent of the animal body
° makes the food soft and palatable
° helps in regulating body temperature
what are the sources of water?
- drinking water
- feed
- metabolic/oxidation water
- bound water
it is consumed by the animals from the outside source.
drinking water
moisture content of all feeds supplies the water requirement of the animal.
feed
it is the water, which is produced due to metabolism of nutrients.
metabolic/oxidation water

factors affecting water requirements/intake:
- Environment
- Dietary factor
- Animal factor
increased environmental temperature and humidity enhanced the water requirement in comparison to cold environment
Environment
high fibrous diet like dry roughages increases water requirement than less fibrous diet.
