Milk, which is the secretion of the mammary glands, is
the only food of the young mammal during the first
period of its life. The substances in milk provide both
energy and the building materials necessary for growth.
Milk also contains antibodies which protect the young
mammal against infection (Bylund, 1995). Milk plays a
tremendous role in building a healthy society and can be
used as vehicle for rural development, employment and
slowing down the migration of the rural population
(Sarwar et al., 2002).
