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.

    Immunoprophylaxis against common dog tick using gut antigen
    (Department of Veterinary Parasitology,College of Veterinary and Animal Science,Mannuthy, 2005) Ajithkumar, K G; KAU; Subramanian, H
    The occurrence of tick infestation in dogs in the Corporation of Thrissur, Kerala, India, was studied in 1200 dogs during a period of one year from July 2004 to June 2005. Four hard tick species viz Rhipicephalus sanguineus, R. haemaphysaloides, Haemaphysalis bispinosa, H. bispinosa var. intermedia were identified. Significant difference in species wise prevalence was found on 124 tick positive dogs. The most prevalent species of tick infesting dogs was found to be R. sanguineus (8.58 per cent) followed by H. bispinosa (1.33 per cent), R. haemaphysaloides (0.33 per cent) and H. bispinosa var. intermedia (0.08 per cent). Three species of ticks namely R. haemaphysaloides, H. bispinosa, and H. bispinosa var. intermedia have been recorded in dogs for the first time from Kerala. The influence of month, season, age, gender and breed on the prevalence rate were observed. Prevalence rates were calculated by month, season, age, gender and breed. No significant difference (P>0.05) of tick infestation during different months was observed due to temperature, relative humidity, and rainfall. No clear pattern of seasonality was observed for R. sanguineus, which was present throughout the year. The different variables considered in the present study such as age and gender were not significantly associated with the presence of tick infestation in dogs. There was a highly significant (P<0.01) association between breed and the intensity of infestation with maximum intensity of infestation in German shepherd dogs. Sites of attachment of ticks were ear, neck, interdigital space, dorsum of the body, eyelids, perianal region, withers, thorax and hind limbs. Highly significant variation (P<0.01) was observed between attachment sites with maximum on ear (84.68 per cent) followed by neck and interdigital space. Tick-bite naive guinea pigs inoculated with gut extracts and Freund’s adjuvant revealed induced immunity against R. sanguineus expressed by altered feeding and fertility parameters consisting of the prolonged engorgement period, reduced engorged female weight and feeding efficiency index, prolonged pre oviposition period, reduced oviposition period, egg mass weight, egg rate conversion efficiency and larval mass. Except the incubation period all the reproductive and feeding parameters differed significantly compared to the control. Inradermal test done on immunised guinea pigs to assess cell mediated immunity revealed both immediate and delayed hypersensitivity reaction. Humoral immune response assessed by agar gel immunodiffusion (AGID) and passive haemagglutination (PHA) revealed that the former was less sensitive compared to the latter. Passive haemagglutination test detected anti tick antibodies as early as 14th day post immunisation. Peak titre 1:128 reached on the 35th day post immunisation.
