ANIMAL NUTRITION GRADE 12 POWERPOINT PRESENTATION

1. Animal Nutrition

2. Animal Nutrition
In the course of evolution,
animals have formed ways to
obtain, process and digest food
as heterotrophs. Some were
able to establish symbiosis with
other organisms to perform
such function.

3. Generally, animals need
carbohydrates, lipids and
protein as basic organic
compounds and supply of
vitamins, minerals and water as
additional nutrient
requirements.

4. Carbohydrates and lipids serve
as energy stores in which the
energy to form adenosine
triphosphate (ATP), the energy
currency of the cell is derived.

5. Essential fatty acids and amino
acids are obtained either from
gut symbiosis or direct food
sources.
Vitamins similar in plants, are
organic compounds that are
only needed in minute amounts
but essential for metabolic
functions.

6. Water soluble vitamins are
regularly consumed whereas
fat-soluble vitamins (A, D, E
and K) are readily stored in the
body.

7. Once an organism
obtained the food, the
next process is how to
digest it such that it
can pass through the
gut wall.
Feeding begins with
physical digestion by
grinding or chewing.

8. Varied ways are
employed by groups of
organism to perform
this process.
Some break up food by
using teeth/jaws,
muscular gizzard in
birds and chewing and
regurgitation in
ruminants.

9. What is ruminants?
Ruminants are hoofed
herbivorous grazing or
browsing mammals that
are able to acquire
nutrients from plant-based
food by fermenting it in a
specialized stomach prior
to digestion, principally
through microbial actions.

11. When the food was chewed
already it is followed by
enzymatic digestion involving
hydrolytic enzymes and a
whole range of digestive
enzymes. The function of the
enzyme is also dependent not
only on the dietary behavior of
the organs but also on the pH
of the surrounding
environment.
