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.

    Immune response of cattle to Boophilus annulatus (Acari : Ixodoidea)
    (Department of Parasitology, College of Veterinary and Animal Sciences, Mannuthy, 1992) Sreekrishnan, R; KAU; Rajamohanan, K
    A study was undertaken to assess the nature and degree of development of acquired resistance in calves against the cattle tick Boophilus annulatus. Observations were made mainly on the development of natural resistance against repeat infestations and the effect of artificial immunization using the tick antigen. Tissue reactions induced by the ticks at the site of bite were also studied. The results indicated the development of resistance in the host, which was gradual and varying in degrees. Immunodiffusion test failed to reveal the presence of tick antibodies in the sera of calves after repeated infestations, indicating that easily demonstrable quantities of antibodies are not developed even after repeated infestations. The cellular reactions at the site of tick – bite revealed the development of a resistant reaction at the site of bite. Studies made on artificial immunization using the whole – tick extract gave varying results. However, the immunodiffusion test using sera of immunized calves revealed that there is a steady maintenance of antibody level throughout the infestation period. Thus, the results obtained in the present study indicate that antibodies are developed against the tick Boophilus annulatus in calves on natural infestations and using the tick antigen, and that there is a clear possibility of immunizing calves against B. annulatus artificially.

    Pathogenesis and treatment of immature Ascaridia galli infection in experimentally infected chicken
    (Department of Parasitology, College of Veterinary and Animal Sciences, Mannuthy, 1992) Padmaja, P B; KAU; Sathianesan, V
    In a study conducted on the pathogenesis and treatment of Ascaridia galli in experimentally infected chicken at different developmental stages of the worm, it had been found that droopiness, whitish diarrhoea, marked reduction in body weight gain, haemorrhage and congestion at different parts of the intestinal mucosa and frothy or blood tinged intestinal contents were the main clinico pathological changes. Histopathological observations in the small intestine were signs of enteritis, jcatarrhalj changes, villar proliferation, desquamation of sub epithelium and villar tips and mild congestion and haemorrhage. A tissue phase was observed in the life-cycle of the nematode at 20th day post infection indicated by the presence of cut sections of the larvae-in the mucosal and submucosal regions. Haematologically, a decrease in the total erythrocyte count, an initial leucopenia followed by leucocytosis, reduction in packed cell volume and percentage of haemoglobin, an increase in the erythrocyte sedimentation rate, percentage of heterophils, eosinophils, mean corpuscular volume and mean corpuscular haemoglobin values and a reduction in the percentage of lymphocytes, monocytes and "mean corpuscular .haemoglobin concentration and an initial basopenia followed by basophilia were observed in infected chicks. For treatment, out of the four anthelmintics tried, namely piperazine hydrate, albendazole, morantel citrate and ivermectin against the infection, albendazole at 50 mg/kg body weight was found to be the most effective, closely followed by morantel citrate at 50 mg/kg body weight and then piperazine hydrate at 500 rag/kg ' body weight. I I Ivermectin at 1 mg/kg body weight subcutaneously was found to be the least effective. The present study with morantel citrate appeared to be the first of its kind as far as it's use against ascairidiasis in poultry was concerned
