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.

    Microbiological quality and shelf-life of raw cow`s milk preserved by lactoperoxidase system
    (Department of Dairy Science, College of Veterinary and Animal Sciences, Mannuthy, 1998) Selvin Joe, J; KAU; Mukundan, M
    A detailed study was carried out to determine the micro-biological quality and shelf- life of raw cow's milk preserved by lactoperoxidase (LP) system. Literature related to the LP-system have been reviewed . •• A total of 6 trails were conducted to obtain reliable data for statistical analysis. In each trail, three litres of raw cow milk was divided into three equal parts of one litre each. One part was kept as a control (C) and LP-system was activated in the other two parts one part with 20: 10ppm (Tl) and other with 20:20ppm (T2) (SCN-:H202), with in two hours of production of milk. The milk samples were stored at 30 +1 DC . . Before the activation of LP- system the micro-biological quality of raw milk, samples were analysed. After the activation of LP-system the micro-biological quality of control and experimental group milk samples were analysed once in every 3 hours, till the samples showed positive on clot-on-boiling (COB) test. Standard plate count, Coliform count, Titratahle acidity, pH, Methylene blue reduction time, one hour Resazurin reduction test, Clot-on boiling test and Alizarin - Alcohol test were the parameters studied. The mean initial SPC of milk samples was 5.280 log cfu per ml. The control milk samples remained 'Good' quality only for 3 hours storage, while the LP-treated milk samples of both Tl and T2 remained 'Good' quality even after 9 hours of storage. 11 \ 1 \ 383 The standard plate count and coliform count (CC) of control milk samples showed a steady increase from the initial period itself, whereas in the LP-treated milk samples of T1 and T2 the SPC and CC showed a reduction than the initial count after 3 hours of storage and both SPC and CC slightly exceeded the initial count even after 6 hour of storage . .. Based on the titratable acidity, the control milk had the acceptable quality (0.18 per cent lactic acid) of only upto 6 hours while the LP-treated milk remained with in the acceptable limit for 12 h. According to the Alizarin - Alcohol test, the control milk remained stable only for 3 hours and the LP- treated milk remained stable for 9 hours of storage at 30+ 1 DC. The milk samples of control group had the shelf-life of 12 hours where as the LP-treated milk samples of T1 and T2 had the shelf-life of 18 hours based on the clot-on-boiling test. The micro-biological quality and shelf-life of milk samples, both T1 and T2 did not show significant difference during the entire period of storage.
