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.

    Comparative study of healing of fracture of metacarpus in calves using different external immobilisation methods
    (Department of Surgery, College of Veterinary and Animal Science, Mannuthy, 1990) Kalyani, Biswas; KAU; Muraleedharan, Nayar K N
    The study was conducted on 18 crossbred male calves divided in three groups of six animals each. Under local anaesthesia (ring block) fracture was created at the midshaft region of the large metacarpal and was reduced. The limb was immobilized with (i) plaster of paris cast (Group A), (ii) transfixation apparatus and plaster of paris cast (group B) and (iii) cast using freshly prepared gum and bandgage (group C). The animals were kept under observation upto six weeks. One animal from each group was sacrificed at the second week and fourth week, and the remaining animals at the sixth week. Oedema was observed distal to the cast in two animals each in Group A and C and four animals in Group B. Pointing of the toes was noticed in three animals of group A, two animals of group B and one animal of Group C. Dragging of the toes was noticed in three animals each of group A and C. All the animals, except one from Group A, were bearing weight on the limb and could get up and lie down unassisted by the first week. Four animals of group A, two animals of group B and three animals of Group C favoured the limb throughout the period. In group A and B, the plaster cast remained intact throughout the period of observation in one animal, had to be changed once in three animals and twice in two animals. In group C, the cast remained intact throughout the period of observation in three animals and was changed once in three animals. Radiodense area was observed at the fracture site in one animal by the first week, in four animals of each group by the second week and in all animals except one by the third week and in all the animals by the fourth week. The fracture line had become less district in one animal of group A, two animals of Group B and one animal of group C by the third week. Ossification of the callus was noticed in all the animals by the fourth week. The fracture line was less distinct in all the animals of Group A, three animals of group B and two animals of Group C. Ossification of the callus and its union was noticed by the fifth week in all the animals except one animal of Group C. However, in group B, ossification was more extensive. Partial obliteration of the fracture line was seen in all except three animals. Extensive ossification of the callus with continuity between the callus of the two fragments and partial obliteration of the fracture line was observed in all the animals, except one animal of Group C by sixth week. The fractured bone cropped after two weeks revealed that in Group A, the fragments were separate and there was mobility at the fracture site but in Group B and C , mobility was less. Soft callus between the fragments and restricted mobility at the fracture site was noticed in the bones cropped at four weeks in animals of all the groups. The callus was well developed and the fragments were firmly fixed by the callus in the bones cropped at six weeks, I all animals of groups A and B and in three animals of Group C. Microscopic examination of the callus at two weeks revealed periosteal and capillary proliferation with zones of necrosis of cortical bone at the fracture site in Group A. In group B and C, the proliferative changes were more marked along with zones of ossification. The callus cropped at four weeks, revealed marked connective tissue and capillary proliferation along with zones of ossification and formation of trabeculae in Group A and C, and in Group B ossification was more extensive. Extensive ossification and interconnected trabeculae continous with the cortical bone was observed in the callus cropped at six weeks in all the three groups. Zones of hyaline cartilage were observed in the callus in the animals of Group A and one animal of Group B and Zone of suppuration in one animal of Group C. Suppuration at the suture line involving the callus and fracture site was observed in one animal of Group C. Partial displacement of the fragments after immobilization was noticed in two animals of group A, three animals of Group B and four animals of Group C.
