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.

    Pathology of cardio-pulmonary disorders in canines
    (Centre of Excellence in Pathology, College of Veterinary and Animal Sciences, Mannuthy, 2003) Pradeep, M; KAU; Vijayan, N
    The present study was undertaken to assess the prevalence and pathology of various cardiac and pulmonary disorders in dogs. The data collected from the autopsy records maintained at the Centre of Excellence in Pathology, Mannuthy and seventy eight samples of heart and lungs from necropsy cases formed the basis of the study. Ninety nine per cent cases showed varying types of cardiac and pulmonary lesions. The highest incidence in the heart was dilated (75.32 per cent) and hypertrophic (15.58 per cent) cardiomyopathies. The other lesions found were hydropericardium, cardiac tamponade, haemorrhage, myocarditis, endocarditis, endocardial fibroelastosis, valvular blood cyst coronary arteriosclerosis and mural. thrombus. Myocardial infarction was found to be confined to the left ventricles and interventricular septum in all the encountered cases (5.19 per cent). Pulmonary congestion (70.51 per cent), haemorrhage (32.47 per cent) and edema (31.17 per cent) were observed with higher incidence rate. The other lesions found in the lungs were bronchitis, emphysema, pneumonia, collapse, infarction, mineralization, ossification, anthracosis and endarteritis obliterans. Metastatic osteosarcoma in the lungs, metastatic lymphosarcoma in the heart and lungs were also observed. The incidence of cardio-pulmonary disorders encountered was relatively high. The need and scope for investigation into the pathological disorders of the heart and lungs of canines were highlighted.

    Pathology of the reproductive system of Japanese Quails (Coturnix coturnix japonica)
    (Centre of Excellence in Pathology, College of Veterinary and Animal Sciences, Mannuthy, 2003) Sivakumar, V; KAU; Mammem, J Abraham
    The present study was undertaken to assess the prevalence and pathology of various diseases affecting the reproductive system of Japanese quails. The data collected from the autopsy records maintained at the Centre of Excellence in Pathology, Mannuthy and one hundred and two samples of reproductive organs obtained from the necropsy cases formed the basis of the study. Retrospective survey revealed the increasing incidence of the reproductive diseases. Out of the 1139 cases encountered, various reproductive diseases were seen in quails at an incidence rate of 25.11 per cent. Oophoritis was the most prevalent among them at an incidence rate of 9.46 per cent. The higher incidence of reproductive diseases could be attributed to the maintenance of large number of breeder stock in the quail farm, which formed the major source for the necropsy samples. The gross and histopathological examination revealed that among the reproductive diseases the highest mortality was due to oophoritis (12.64 per cent) followed by egg bound (11.75 per cent). Other cases were salpingitis, egg impaction, ovarian fibroma, testicular hypoplasia and orchitis. Escherichia coli, Klebsiella and Proteus were isolated from various cases. The incidence of pathological disorders encountered was relatively high. The need and scope for investigation into the diseases affecting quail reproductive system were highlighted.

    Pathology of gastro-intestinal discorders in piglets
    (Centre of Excellence in Pathology, College of Veterinary and Animal Sciences, Mannuthy, 2003) Smitha, S; KAU; Divakaran Nair, N
    The present study was undertaken to assess the prevalence and pathological disorders of the gastro-intestinal system of piglets. The results of the present investigation and evaluation of the data from the records revealed a high incidence of gastro-intestinal disorders to the level of eighty eight per cent. A detailed systematic examination of fifty piglet carcasses brought for autopsy during the period of investigation was conducted and the gross and histopathological lesions were studied in detail and were classified based on age and sex. Higher incidence of gastro-intestinal lesions was recorded in piglets aged 10-20 days and their possible causes are described. Vascular and degenerative changes were the predominant lesions, followed by inflammation. Among the inflammatory changes, catarrhal gastro-enteritis was the most prevalent lesions observed. Escherichia coli and Klebsiella were isolated from such cases and are suspected as the possible pathogenesis has been described. Viral etiology was also suspected in certain cases as the infiltrating cells appeared predominantly Iymphocytes. Besides these ulcers were recorded in the stomach and the intestinal tract. Salmonella cholerae suis was isolated from the intestinal ulcers. Bacterial isolations were obtained in the intestine, liver, heart blood and sow's milk. A total of 17 bacterial isolations were obtained from 11 animals. Their role in the causation of gastro-intestinal disorders have been explained. Coincident with various gastro-intestinal disorders, liver of 30 cases and mesenteric lymph nodes of 28 cases revealed variety of vascular, degenerative and inflammatory lesions. In one case 'with suppurative hepatitis, Salmonella cholerae suis was isolated. The variable degrees of lymphoid depletion, degeneration and necrosis of lymphoid follicles of mesenteric lymph nodes and the Iymphocytes of Peyer's patches indicated immunosuppression. The vascular and degenerative lesions, without any evidence for infections etiology observed in the gastro-intestinal tract and liver suggested the involvement of some toxic factors. Further the higher incidence of the disorders in the young ones, the isolation mostly of the resident flora of the intestinal tract and the lymph node changes indicated the necessity for an in depth study on the role of factors like immune status of the animals and eo-pathogens in the causation of gastro- intestinal disorders in piglings,

    Pathology of the respiratory system in rabbits
    (Centre of Excellence in Pathology, College of Veterinary and Animal Sciences, Mannuthy, 2003) Rekha, S; KAU; Lalithakunjamma, C R
    The present study was undertaken .to assess the pathology of the respiratory system in rabbits. The results of the study revealed a high incidence (80 per cent) of respiratory disorders. A detailed systematic examination of fifty cases of rabbit carcasses brought for autopsy during the period of investigation was conducted and the gross and histopathological lesions were studied in detail. Vascular and inflammatory lesions were predominant in the trachea and the lungs. Degenerative changes were seen in the trachea, pleura and the lungs. Bronchial lymph nodes revealed mild congestion and depletion of lymphocytes occasionally. A case of alveolar carcinoma was encountered in the present study. Adenomatous proliferation of the bronchial epithelium was seen in one case. Bacterial isolations were obtained from the trachea and the lungs. Escherichia coli (16 cases), Staphylococcus sp.(3 cases) and Proteus sp. (1 case) were obtained. The need and the scope of investigation into the pathological disorders in the respiratory system ofthe rabbits were highlighted.

    Prevalance and pathology of brain disorders in cattle
    (Centre of Excellence in Pathology, College of Veterinary and Animal Sciences, Mannuthy, 2003) Balasubramanian, M; KAU; Divakaran Nair, N
    The present study was undertaken to assess the prevalence and pathology of various brain disorders in cattle. The data collected from the autopsy records maintained at the Centre of Excellence in Pathology, Mannuthy and fifty-two samples of brain obtained from both the slaughtered cattle and autopsy cases formed the basis of the, study. Gross lesions were not so evident except for the meningeal congestion, which accounted to 70 per cent of the cases. Congestion and haemorrhages were found consistently in the slaughtered cattle, which could be attributed to stunning effect. The other major lesions were well appreciated by detailed histopathological examination of ten different areas of the brain in each of the cases. These included vascular changes, neuronal degeneration, inflammatory changes, gliosis, pigmentation and neoplasia. Two cases revealed intra neuronal cytoplasmic inclusions of which one was due to rabies and the other was attributedto viral etiology. Bovine spongiform encephalopathy was not found to be present in any of the cases in the present study. Based on the observations made here, it was suggested that diagnosis of rabies by impression smear examination alone is not sufficient and needs examination by FAT or Immunoperoxidase techniques. The incidence of pathological disorders encountered was relatively high. Thus, the need and scope for investigation into the pathological disorders of bovine brain were highlighted.
