Indigenous and crossbred pig genetic resources in India
Pig is widely distributed in all the eco-regions in India. Pig farming is an important occupation of the rural society especially the tribal masses. People of certain ethnic groups prefer to keep more pigs, especially black ones, for festivals and ceremonial purposes.
Indigenous pig germplasm: Out of total pig population, 79.03% are indigenous and non-descript. Most of these population are yet to be characterized with proper scientific intervention. These pigs are of smaller size and almost no efforts have been made for any conservation and selection to improve its economic traits, such as litter size, birth weight, weaning weight, average daily gain, feed conversion efficiency and carcass traits. These animals are well adapted to hot and humid environment and presumably have better disease tolerance. The indigenous pigs of India have been identified as a distinct group as a result of gradual domestication of wild pigs to their surroundings. These pigs differ in their characteristics and colour from region to region within the country depending the topography and climatic conditions. The details of the native / indigenous and exotic / crossbred population of pigs in India and population of major pig rearing states are given in Table 1.

Some other prominent variants of pigs like Andaman Wild, Andaman Local, Ankamali, Burudi, Dome, Golla, Lepchamoun, and Pondi/Jhinga are yet to be characterized for registration. The pig breeds evolved through natural selection over a long period. The inherent abilities of indigenous breeds have enabled them to adapt better to the agro-climatic conditions prevailing in their home tract.

Nicobari pigs are semi-feral in nature and no systematic or scientific management is followed by the tribes.As such, tribals were not aware much about the farming system and the pigs were reared under free-range system. Generally, pigs are not reared for commercial purposes. This breed is well adapted to the local environment of Nicobar and can survive with a very low level of management.

Crossbred pig germplasm: Piggery developmental programmes undertaken by the central and state departments namely; Department of Animal Husbandry and Dairying, Government of India, Veterinary and Animal Husbandry Departments and Animal Resource Development Departments of different states and research organizations viz. Indian Council of Agricultural Research (ICAR), Central Agricultural Universities (CAU), State Agricultural/Veterinary University (SAUs) have resulted in noticeable progress over the time. During the initial period of development, focus was on genetic improvement of indigenous pig through selective breeding. Subsequently exotic breeds were introduced in India and efforts were made for stabilize their performance in Indian agro-climatic condition. Consequent to slow progress of indigenous pigs and based on demand, crossbreeding of native pigs with exotic boars gained momentum in different parts of the country. Several crossbred pig varieties have been reported by different organizations.
The crossbred pigs include high-producing varieties viz. Rani, Asha, HD K-75, Lumsniang, Jharsuk, Mannuthy White, TANUVAS KPM Gold, SVVU T-17 and Landlly suitable for different agro-climatic condition of the country.
