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.

    Influence of dietary supplementation of protein and iodine on tapioca toxicity
    (Department of Physiology and Biochemistry, College of Veterinary and Animal Sciences, Mannuthy, 1994) Abdul Latheef; KAU; Ramakrishna Pillai, M G
    A three phase experiment was carried out to assess the level of cyanogenic glycoside (CNG) content in seven varieties of tapioca, its removal by various processing methods and its effect on metabolism in rats and kids. The role of dietary protein and iodine in modifying the deleterious effects of cyanide v/as investigated. Histopathological studies on the liver, pancreas and heart were also carried out in rats. The first phase of the study revealed that CNG content in terms of cyanide varied from 40.86 + 2.79 to 186.31 + 5.30 ug/g of fresh tuber with the lowest concentration in 'M-4' and higher concentrations in 'H-165' and 'Karkidakkan'. Processings like boiling and sun drying lowered the CNG content by about 50 per cent of the original. In the second phase 60 male albino Wistar rats, divided into six groups were given the following diet. Group I - Protein = 15%; Tapioca = Nil; Iodine = Nil Group II - Protein = 15%; Tapioca = 30%; Iodine = Nil Group III - Protein = 7.5%; Tapioca = 30%; Iodine = Nil Group IV - Protein = 7-5%; Tapioca v/ithout HCN = 30%; Iodine = Nil Group V - Protein = 15%; Tapioca = 30%; Iodine = 0.17 mg/kg Group VI - Protein = 22-5%; Tapioca = 30%; Iodine = 0.17 mg/kg Performance of rats was evaluated by recording growth rate, feed consumption and feed efficiency for a period of 12 weeks. Dry matter digestibility was also determined over a period of 24 h. At the end of 10th, 11th and 12th week of the study the rats were sacrificed and endocrinological, biochemical and histopathological evaluation of blood/serum and tissues were made. Performance of rats v/as poor on tapioca-based diet not supplemented with iodine (Groups II and III). Rats fed on protein deficient diet in the presence of cyanide containing tapioca were the most affected (Group III) . However, there was no significant variation in the performance in Groups V and VI compared to Group I when tapioca-based diet were supplemented with iodine. The digestibility of dry matter in six groups of rats was almost inversely related to the quantity of feed consumed. There was significant increase in DNA and decrease in protein content of thyroid thereby increasing the DNA: protein ratio, followed by extremely low levels of thyroxine and hyperplasia of the thyroid in Group III. In Group II alsothere occurred a significant reduction in the levels ofthyroxine and a resultant hypertrophy of the thyroid.
