| The domestication of indigenous
cattle appears to have taken place in the area of present
Afghanistan, Sind and Baluchistan before 4000 BC. The
seals from Sivikotada in Gujarat and Kalibanga in Rajasthan
show images of domestic animals probably reared by Harappans
(2200 BC to 1600 BC). Fossils of Bos acutifrons have
been discovered in Siwaliks, which are regarded as possible
wild ancestors of cattle. These findings suggest that
domestication of cattle in Indian Subcontinent antedates
Europe and North Africa.
The indigenous cattle (Bos indicus) differ from Bos
Taurus cattle found in Europe and North Africa in morphological
characters. A prominent hump, a long face, upright horns,
drooping ears, a dewlap and slender legs characterize
the indigenous breeds. Indigenous cattle have lower
basal metabolic rate, better capacity for heat dissipation
through cutaneous evaporation and thus adaptation to
tropical heat and resistance to diseases specially the
thick-borne diseases than Taurus cattle. Indigenous
breeds are well known for heat tolerance, hardiness
and ability to survive and perform even under stressful
conditions and low input regimes. Different breeds of
indigenous cattle were evolved over centuries to suit
to different agro ecological situations.
Indian subcontinent is a rich source of diverse animal
germplasm, and only a very few countries have such a
large number of breeds of farm animals with such a wide
genetic diversity. India has contributed richly to the
international livestock gene pool and improvement of
animal production in the world. The cattle in India
are broadly categorized in to 3 groups, milch breeds,
draught breeds and dual-purpose breeds. There are nearly
thirty breeds of cattle in addition to a large number
of which are generally small in size and low producing.
It is estimated that only about 18% of the total cattle
in India belong to well defined breeds.
