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.

    Treatment of fracture of metacarpus in calves using autogenous rib graft
    (Department of Surgery, College of Veterinary and Animal Sciences, Mannuthy, 1994) Syam, K Venugopal; KAU; Jalaluddin
    The present study was conducted on 12 apparently healthy, crossbred male calves six to twelve months of age and weighing 50 to 80 kg, divided into two groups of six animals each (Group A and B). A transversa mid shaft fracture was created on the right metacarpus by open method under sedation with Triflupromazine hydrochloride at the rate of 0.25 mg/kg body weight IM and diazepam at the rate of 0.20 mg/kg body weight IV followed by local infiltration analgesia using two percent solution of lignocaine hydrochloride. In group A, the fracture was reduced and the fragments were retained in position by placing two freshly cropped autogenous rib grafts subperiosteally, one on the anterior aspect and the other on the posterior aspect of the metacarpus. The grafts were fixed in position by hemicerclage wiring using stainless steel wires at two places. The limb was immobilized with four cotton padded bamboo splints and plaster of paris cast. In group B, the fracture was reduced and the wounds were sutured. The limb was immobilised with four cotton padded bamboo splints and plaster of paris cast. A sham operation was performed on the left metacarpal region on the same day by incising the skin upto the periosteum and suturing it. By the end of the second week, all the animals could get up and lie down without assistance. Four animals of Group A and three animals of Group B started bearing weight on the fractured limb from varying periods. Favouring of the fractured limb, limping and nodding of the head were observed in all the animals. Pawing action with the fractured limb and stumbling were observed in two animals each from both the groups. Dragging of the toes was observed only in one animal, in group B. Infection and suppuration at the suture line was observed in one animal of group A. Plaster of paris cast remained intact throughout the period of observation in all the animals. One animal from group A and four animals from group B required reinforcement of plaster cast. Marked displacement of the distal fragment was noticed in one animal each in Group A and B. But deviation of the distal fragment at the fracture site was observed in one animal of Group A and four animals of Group B. Grafts were in position in all the animals throughout the the period of observation. They became radiographically indistinguishable from fourth week onwards. Radiographically visible callus was found by the third week in group A and by the first week in group B. Partial obliteration of the fracture gap was observed by the end of fourth week in both the groups. Fractured bone cropped after two weeks revealed mobility between the fragments in both the groups. The bones cropped after four weeks showed well developed callus uniting the fragments and there was no mobility at the fracture site in both the groups. The callus developed at the end of six weeks and four weeks were grossly similar in both the groups. Histological examination of the callus cropped at second week in group A revealed periosteal and capillary proliferation along with new trabecular bone formation around the graft site. In group B, fibrous tissue proliferation exceeded trabecular new bone formation. The callus cropped at fourth week in group A revealed extensive areas of graft vascularisation and zones of new bone formation. In group B, cartilage formation was seen along with zones of new bone formation and fibrous tissue proliferation. Replacement of the graft tissue with proliferating blood vessels, osseous tissue and connective tissue were observed in the callus cropped from the animals of group A, at the end of six weeks. In group B, well developed internal callus, extensive periosteal callus, proliferation of fibrous tissue and trabecular ossification centres were observed. Fibrocartilage was noticed in the callus in one animal of group B.
