The All India Co-ordinated Research Project (AICRP) on Pig, AAU, Khanapara, Guwahati-781022 is situated in the College of Veterinary Science, Khanapara, Guwahati- 781 022. (Latitude 26.12549N, Longitude 91.82426E).
The Project started its journey during IVth five year plan (1970-1971). It was sanctioned on 01.10.1970 with the main objective of studying the performance of purebred exotic pig (Landrace) under existing managemental conditions.
During VIth Five Year Plan (1980-81), the technical programme of AICRP on Pig was remodeled with a view to carry out research work on indigenous pigs then subsequently on the crossbreeding between indigenous female with appropriate exotic breed (Hampshire).
Objectives of the project :
1. To study the performance of indigenous pigs under optimal managemental conditions.
2. To produce crossbred by crossing indigenous gilts with exotic boars and to assess their performance in respect of their efficiency of feed conversion, production and reproduction.
3.To evolve economic pig ration with locally available feed ingredients, conventional and unconventional.
4.To select animals from within half breeds with faster growth on economic ration(s) to produce superior strain of improved pigs.
5. To study the incidences of various diseases in pigs, so as to suggest areas for undertaking research to provide optimum health care.
The AICRP on Pig, AAU, Khanapara has developed a variety of pig with 75% Hampshire and 25% indigenous inheritance (75%H25%I) which has been stabilized through 16 generations of inter-se mating. This variety is named as HD-K75 where “H” signifies 75% Hampshire, “D” signifies Desi (Indigenous) pig of Assam and “K” represents the place of it’s development i.e. Khanapara. The first litter of this variety was obtained on 11.11.1988. The 16th generation of inter-se mating has been completed in 2016. This newly developed variety of pig is found to be far superior to the indigenous pigs of Assam in terms of productive and reproductive performances. This variety has already gained popularity among the farmers of Assam as well as entire North Eastern Region of India because of its high production potential, consistency in performance and adaptability to the local environment.This variety of pig is medium in size and has erect ears. The coat colour is black usually with a white belt in the shoulder region which might extend upto the forelimbs.
The ICAR-AICRP on pig, AAU, Khanapara has played an important role since its inception for development of pig production in the state and neighboring states through various ways by selling of quality piglets, elite gilts / sows and boars at nominal price to the interested farmers; training programme, awareness program, exhibition, demonstration and distribution of leaflet /booklet. Besides this different research works also carried out under the project by the Department of Animal Genetics, Animal Nutrition, Animal Reproduction Gynaecology, Animal Physiology, Livestock Production Management, Veterinary Microbiology, Veterinary Medicine etc.

Significant achievements in respect of pig breeding, nutrition, reproduction including endocrinology etc .A. Animal Breeding & Production:Breeding programmes were developed to generate the following genotypes/genetic groups:• Crossbreds having 50:50 inheritance from Hampshire and indigenous pigs (50% Hampshire Cross)• Crossbreds having 75% Hampshire and 25% indigenous inheritance (HD-K75)• Genetic improvement of indigenous pig through pure breed selection programme was conducted in AICRP under agro- climatic conditions of Assam.• Litter size at birth and weaning showed continuous improvement over the years. Similarly, the growth rate and body weight at 32 weeks was also increased significantly.• Crossbred had higher litter size and weight, growth rate and better feed conversion efficiency than indigenous pig.• Hampshire crossbred (75%) had higher value of litter traits than their respective 50% crossbred.• The crossbreds had lower back fat thickness and higher lean cuts in their carcasses than the indigenous pigs.B. Animal Nutrition:Various research works were carried out in respect to incorporate locally available feed resources to evolve an economic pig ration. It was revealed that banana stem, root crop (tapioca, sweet potato etc.), brewery waste, tea waste, silk worm pupa, water hyacinth and vegetable wastes like cabbage, collocassia etc. could be used for developing economic ration for pig.C. Pig Reproduction and Endocrinology• Indigenous pigs compared unfavorably with exotic pigs in respect of litter size and weight at birth, weaning, growth rate, efficiency of feed utilization and lean meat production.• All groups of crossbreds had higher litter productivity, growth rates and efficiency of feed utilization than the indigenous pigs.• Hampshire crossbreds carrying 75% exotic inheritance had higher values of litter traits than those respective half-bred.Collection of boar semen and artificial insemination:Technology was developed for collection of boar semen using a dummy. Artificial insemination technology by using liquid semen has been standardized in collaboration of Department of Animal Reproduction and Gynaecology.
