kg cow
· Many experiments have been
made to find out what amounts of food an animal needs to produce milk, meat,
work.

This requirement changes for each kind of production and
according to the amount of production.
Production requirement to give 3
litres of milk
Many experiments have been made for each kind of animal to find
out:
· the pregnancy requirement when
it is expecting young;
· the production
requirement when the mother is giving milk;
·
the requirement for growth when the young animal is growing.
Tables have been made which show for each animal the maintenance
requirement according to weight production requirement according to production
pregnancy requirement when it is expecting young growth requirement when it is
growing.
To find out what an animal needs, add up all these requirements.
For example:
A cow weighing 300 kg which produces 3 litres of milk needs:
|
maintenance requirement: |
2.6 kg |
|
production requirement |
1 |
|
Total |
3.6 kg |
Total requirement of 300- kg
producing 3 litres of
milk
