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.

    Effect of certain biopesticides and irradiation on the developmental stages of myiasis producing flies
    (Department of Parasitology, College of Veterinary and Animal Sciences,Mannuthy, 1998) Subramanian, H; KAU; Rajamohanan, K
    A study was undertaken on the prevalence of cutaneous myiasis in domestic animals and its control using bio-pesticides and gamma irradiation. The prevalence of cutaneous myiasis in domestic animals was found to be 205 (2.08 per cent) among .the 9861 animals screened. The peak of infestation was noted in the month of January. In host-wise and parasite-wise the highest incidence was noted in cattle (63.41 per cent) and the majority of infestation was produced by Chrysomya bezziana larvae (90.73 per cent). Methoprene at 1 to 50 ppm concentration caused only moderate mortality on larvae but significantly increased the mortality rate on eggs, prolonged the larval phase, increased the formation of larval pupal intermediaries and adult deformities and reduced the adult emergence. Diflubenzuron at 0.5 to 5 ppm caused 55 to 100 per cent larvicidal effect due to lowered chitin content of 18.42 to 52.11 per cent in larval cuticle. Bacillus thuringiensis var israelensis produced only moderate larval mortality at 160 to 800 ppm in myiasis producing flies. Azadirachtin at 10.5 to 15 ppm produced 100 per cent mortality in eggs and larvae. Significant antifeedant, ovipositional deterrent and repellant effects were also produced by Azadirachtin. Among the extracts of Acarus calamus, studied, petroleum ether extract at 2.5 per cent concentration gave 82.5 to 100 per cent mortality of the larvae. Moderate antifeedant, ovipositional deterrent and repellant effects were also noticed. The petroleum ether extract produced 100 per cent sterility at 0.1 to 1 per cent concentration by preventing the development of ovarian follicles. Three day old pupae of myiasis producing flies exposed to r-rays gave excellent sterility effect at 2000 to 4000 rads radiation exposure without any other deleterious effect in the flies. Diflubenzuron at 5 ppm concentration showed the highest larvicidal effect (88.5 per cent) in natural cases of cutaneous myiasis.

    Prevalence, immune response and treatment of mite infestation in rabbits
    (Department of Parasitology, College of Veterinary and Animal Sciences, Mannuthy, 1998) Regu Ravindran; KAU; Subramanian, H
    The prevalence, immune response and treatment of mite infestation in rabbits of Mannuthy and Thrissur, Kerala were studied in detail during a one year period from August 1997 to July 1998. The total prevalence of mange in rabbits was 56.9 per cent. The prevalence increased as temperature decreased, humidity and rainfall increased. The mite infestation was more prevalent during rainy months of the year. Notoedres cuniculi, Psoroptes cuniculi, Listrophorus gibbus and Cheyletiella parasi tivorax were identified as the four species of mites infesting rabbits. N. cuniculi showed maximum prevalence while C. parasitivorax the least. The New Zealand White rabbits were more prone to mite infestation while crossbreds/local breeds showed least prevalence rate. Whole body extract of P. cuniculi was used for immunization of rabbits. Agar gel precipitation and counter immuno electrophoresis revealed a maximum of three clear strong precipitation lines with the sera from immunized animals. The majority of sera from infested animals produced only single precipitation line. The passive haemagglutination assay revealed a maximum mean serum antibody titre of 1: 12513 against sera from immunized animals while sera from chronically infested animals showed a very low mean titre of1:22. Dermal reaction of the inoculated antigen into the skin of normal, infested and immunized rabbits showed increased skin thickness in all the three groups which was maximum by 12 to 24 hours after inoculation of antigen. The increase in skin thickness was significantly less in normal groups compared to the other two groups. Treatment trials conducted against Notoedric and Psoroptic mange showed that topical application of Karanji oil and single subcutaneous administration of Ivermectin at the dose of 0.3 mg/kg were highly effective in curing mange. Dimilin (Diflubenzuron) was not only ineffective against mange but also increased the severity of lesion and mite number. Ektodex{amitraz) was not 100 per cent effective on single application at 0.6 per cent concentration. Karanji oil which is cheaper and effective than Ivermectin is suitable for small scale farmers in curing rabbit mange.
