are water soluble and y not fat soluble

Deficiency: Its deficiency causes
epilepsy and convulsion(jerks)

Vitamin B12 (cobalamin)
Function: It is invoved in metabolism
Deficiency: Its deficiency cause slow
growth and less reproduction


Cholin

It is part of lecithin
Deficiency: Its deficiency cause fatty liver

Biotin.
Function: It is also invoved in metabolism
Deficiency: Its deficiency cause dermatitis





Fat soluble vitamins
include
 They contain
C,H,O
 They are stored in
the body
 They are secreted
into faeces
 They cause
toxicity
 They are not
synthesized by
body but
sometimes
synthesized
 They are dietary
essential
 General source for
fat soluble vitamin
are green pasture,
green fodder,
green leafy hay,
fish liver oil,
yellow corn
grains, sunlight

5. Vitamin A

 Its requirement is expressed
in IU
Function:

(2) It increases conception rate
Deficiency: Its deficiency cause night
blindness
(2) Its deficiency also causes poor
conception

Vitamin D
It is in two forms
D2: Ergocalciferol
It is mostly present in plants
D3: cholicalciferol
It is synthesized by animal body in
sunlight
Function:(1) It helps in bone
development
(2) It also help in to maintain mineral
balanced in the body
Deficiency: Its deficiency cause
osteomalcia and rickets
