Kerala Agricultural University, Thrissur

The history of agricultural education in Kerala can be traced back to the year 1896 when a scheme was evolved in the erstwhile Travancore State to train a few young men in scientific agriculture at the Demonstration Farm, Karamana, Thiruvananthapuram, presently, the Cropping Systems Research Centre under Kerala Agricultural University. Agriculture was introduced as an optional subject in the middle school classes in the State in 1922 when an Agricultural Middle School was started at Aluva, Ernakulam District. The popularity and usefulness of this school led to the starting of similar institutions at Kottarakkara and Konni in 1928 and 1931 respectively. Agriculture was later introduced as an optional subject for Intermediate Course in 1953. In 1955, the erstwhile Government of Travancore-Cochin started the Agricultural College and Research Institute at Vellayani, Thiruvananthapuram and the College of Veterinary and Animal Sciences at Mannuthy, Thrissur for imparting higher education in agricultural and veterinary sciences, respectively. These institutions were brought under the direct administrative control of the Department of Agriculture and the Department of Animal Husbandry, respectively. With the formation of Kerala State in 1956, these two colleges were affiliated to the University of Kerala. The post-graduate programmes leading to M.Sc. (Ag), M.V.Sc. and Ph.D. degrees were started in 1961, 1962 and 1965 respectively. On the recommendation of the Second National Education Commission (1964-66) headed by Dr. D.S. Kothari, the then Chairman of the University Grants Commission, one Agricultural University in each State was established. The State Agricultural Universities (SAUs) were established in India as an integral part of the National Agricultural Research System to give the much needed impetus to Agriculture Education and Research in the Country. As a result the Kerala Agricultural University (KAU) was established on 24th February 1971 by virtue of the Act 33 of 1971 and started functioning on 1st February 1972. The Kerala Agricultural University is the 15th in the series of the SAUs. In accordance with the provisions of KAU Act of 1971, the Agricultural College and Research Institute at Vellayani, and the College of Veterinary and Animal Sciences, Mannuthy, were brought under the Kerala Agricultural University. In addition, twenty one agricultural and animal husbandry research stations were also transferred to the KAU for taking up research and extension programmes on various crops, animals, birds, etc. During 2011, Kerala Agricultural University was trifurcated into Kerala Veterinary and Animal Sciences University (KVASU), Kerala University of Fisheries and Ocean Studies (KUFOS) and Kerala Agricultural University (KAU). Now the University has seven colleges (four Agriculture, one Agricultural Engineering, one Forestry, one Co-operation Banking & Management), six RARSs, seven KVKs, 15 Research Stations and 16 Research and Extension Units under the faculties of Agriculture, Agricultural Engineering and Forestry. In addition, one Academy on Climate Change Adaptation and one Institute of Agricultural Technology offering M.Sc. (Integrated) Climate Change Adaptation and Diploma in Agricultural Sciences respectively are also functioning in Kerala Agricultural University.

    Seroprevalence of HydroPericardium Syndrome in Broiler chickens
    (Department of Microbiology, College of Veterinary and Animal Sciences, Mannuthy, 2000) Binu, T V; KAU; Koshy John
    In the present study, seroprevalence of hydropericardium syndrome (HPS) in broiler chickens in Kerala was evaluated. The results of agar gel precipitation test (AGPT), counter imrnunoelectrophoresis (eIE) and indirect enzyme linked imrnunosorbent assay (ELISA) were compared in detecting HPS antibodies. A total of 350 sera samples were collected from different parts of Kerala. In the first phase, 50 sera samples were screened by AGPT, eIE and indirect ELISA. Three samples were found positive by AGPT and eIE. Seven samples were found to be posi ti ve by indirect ELISA. Based on the comparison, another 300 samples were screened using indirect ELISA and 17 samples were found to be positive. A total of 24 samples were found positive for HPS antibodies out of 350 samples screened by indirect ELISA. The seroprevalence of 6.86 percentage was evaluated in broiler chickens in Kerala using indirect ELISA. The syndrome was experimentally reproduced in three-week-old broiler subcutaneous inoculation viz. , chicks. intramuscular, Various routes of and intraperitoneal routes were tried. The lesions were more pronounced when the birds were inoculated by subcutaneous route. Chick mortality was high on the fourth day. Electron microscopy of the infected liver homogenate revealed hexagonal virus particles of about 75 nm in size. These are suggestive of adenovirus. Histopathology of necropsied birds showed degeneration and necrosis of myocardial fibres, necrosis of hepatocytes and focal areas of coagulation in liver. Basophilic intranuclear inclusion bodies were demonstrated in hepatocytes. Vacuolar degeneration of kidney tubules, lymphoid depletion of bursa, vascular sclerosis of spleen and congestion and oedema of lungs were also seen.
