Assam Agricultural University, Jorhat

Assam Agricultural University is the first institution of its kind in the whole of North-Eastern Region of India. The main goal of this institution is to produce globally competitive human resources in farm sectorand to carry out research in both conventional and frontier areas for production optimization as well as to disseminate the generated technologies as public good for benefitting the food growers/produces and traders involved in the sector while emphasizing on sustainability, equity and overall food security at household level. Genesis of AAU - The embryo of the agricultural research in the state of Assam was formed as early as 1897 with the establishment of the Upper Shillong Experimental Farm (now in Meghalaya) just after about a decade of creation of the agricultural department in 1882. However, the seeds of agricultural research in today’s Assam were sown in the dawn of the twentieth century with the establishment of two Rice Experimental Stations, one at Karimganj in Barak valley in 1913 and the other at Titabor in Brahmaputra valley in 1923. Subsequent to these research stations, a number of research stations were established to conduct research on important crops, more specifically, jute, pulses, oilseeds etc. The Assam Agricultural University was established on April 1, 1969 under The Assam Agricultural University Act, 1968’ with the mandate of imparting farm education, conduct research in agriculture and allied sciences and to effectively disseminate technologies so generated. Before establishment of the University, there were altogether 17 research schemes/projects in the state under the Department of Agriculture. By July 1973, all the research projects and 10 experimental farms were transferred by the Government of Assam to the AAU which already inherited the College of Agriculture and its farm at Barbheta, Jorhat and College of Veterinary Sciences at Khanapara, Guwahati. Subsequently, College of Community Science at Jorhat (1969), College of Fisheries at Raha (1988), Biswanath College of Agriculture at Biswanath Chariali (1988) and Lakhimpur College of Veterinary Science at Joyhing, North Lakhimpur (1988) were established. Presently, the University has three more colleges under its jurisdiction, viz., Sarat Chandra Singha College of Agriculture, Chapar, College of Horticulture, Nalbari & College of Sericulture, Titabar. Similarly, few more regional research stations at Shillongani, Diphu, Gossaigaon, Lakhimpur; and commodity research stations at Kahikuchi, Buralikson, Tinsukia, Kharua, Burnihat and Mandira were added to generate location and crop specific agricultural production packages.

    SERO-PREVALENCE, MOLECULAR DETECTION AND ASSESSMENT OF FARM LEVEL RISK FACTORS OF JAPANESE ENCEPHALITIS VIRUS INFECTION IN PIGS OF LAKHIMPUR DISTRICT OF ASSAM
    (College of Veterinary Science, Assam Agricultural University Khanapara, Guwahati-781022, 2016-07) Rajkhowa, Uttam; Barua, A. G.
    An investigation was carried out in the Department of Veterinary Public Health, Faculty of Veterinary Science, Assam Agricultural University, Khanapara, Guwahati-22, to study the Sero-prevalence, molecular detection and assessment of farm level risk factors of Japanese encephalitis virus infection in pigs of Lakhimpur district of Assam. The samples were collected from 145 pig farms both organized and unorganized in 9 blocks of Lakhimpur district with a total 58 numbers of samples per block of the district, during the year 2015-16 . Out of 522 serum samples collected, 20 (3.83%) were found to be sero-positive by Indirect ELISA for Japanese encephalitis virus infection. Among the 9 blocks the highest prevalence was found in Boginadi block (8.62%) followed by North Lakhimpur (6.90%), Nowbachia (6.90%), Dhokuakhana (5.17%), Bihpuria (3.45%), and Karunabari (3.45%). No prevalence was found in Telahi and Narayanpur blocks (0%). Age wise higher prevalence (4.46%) was recorded in the age group above 12 months, sex wise in female (4.41%) pigs and breed wise slightly higher prevalence was observed in local pigs (4.11%). however there was no significant association in sero-prevalence of Japanese encephalitis with respect to age , sex , and breed of pigs. All the samples subjected for RT-PCR were found to be negative for E gene of JEV by RT-PCR. Assessment of the farm level risk factors included in the present study viz. closeness to rice fields, standing water sources, exposure of wild bird to pig farms, mosquito exposure to pig sheds showed that all the risk factors were significantly associated with sero-positiviy of JE in pig farms.
