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.

    Evaluation of antistress and growth promoting effect of aswagandha (Withania somnifera) in broiler chicken
    (Department of Veterinary Physiology, College of Veterinary and Animal Sciences, Mannuthy, 2009) Rekha P, Raghavan; KAU; Sreekumar, K P
    The purpose of the study was to asses the antistress and growth promoting effect of Withania somnifera in broiler chicken. Sixty numbers of day old broiler chicks (vencob) procured from a commercial hatchery were reared under standard managemental conditions. At day old they were randomly divided into six groups (G1 to G6) with ten birds in each group. The study was conducted upto sixth week of age. The birds in various groups were as follows, G1- Normal , G2- Normal +5 g W. somnifera per kg feed, G3- Normal + 10 g W. somnifera per kg feed, G4- Stressed, G5- Stressed + 5 g W. somnifera per kg feed, and G6- Stressed + 10 g W. somnifera per kg feed. Production parameters such as body weight, weekly weight gain, feed consumption and feed efficiency were evaluated on weekly basis. All birds were immunized with 1ml of 7 per cent sheep red blood cells intravenously five days before subjecting to stress, for the evaluation of immune status. Stress was induced from four weeks to six weeks of age by reducing the floor space for a bird 1/3rd (372 cm2/ bird) of the optimum requirement (1116 cm2/bird). Blood samples were collected from wing vein, five days and one day before the induction of stress as well on day one, three, six, nine, twelve and fifteen days after the induction of stress. Haematological parameters such as total erythrocyte count (TEC), total leukocyte count (TLC), haemoglobin (Hb), heterophil lymphocyte ratio (H:L), mean corpuscular volume (MCV), mean corpuscular haemoglobin (MCH), mean corpuscular haemoglobin concentration (MCHC) and volume of packed red cells (VPRC) were determined. Serum was utilized for analysis of total protein, albumin, globulin, glucose, C-reactive protein (CRP), alanine amino transferase (ALT) and total cholesterol. The A:G was derived. The immunological status was studied by haemagglutinin assay (HA). Tissues from liver were used for estimating tissue lipid peroxidation (LPO) and reduced glutathione (GSH) levels. The mucous membrane of proventriculus and duodenum were used for protease and amylase estimation respectively. The whole pancreas was used for pancreatic lipase estimation. Slaughter weights, carcass weight, giblet weight, weight of organs (spleen, bursa and adrenal) were also studied. The result of the present study revealed that supplementation W. somnifera did not affect the normal growth of broiler chicken. There was not much variation in slaughter weight, carcass weight and weight of organs between W. somnifera supplemented and not supplemented group. In stressed birds supplementation of W. somnifera ameliorated the stress related reduction in organ weight. Supplementation of W. somnifera did not affect the haematological parameters such as Hb, VPRC, TEC, TLC, MCV, MCH, MCHC and H:L in normal birds. Supplementation of W. somnifera to stressed birds reduced the stress induced increased TEC, MCV and H:L in birds. The supplementation of W. somnifera did not affect the serum total protein, albumin, globulin and A:G in normal birds. But in stressed birds the increased total protein was decreased by supplementation of W. somnifera. The supplementation of W. somnifera did not cause a sustained increase in ALT values revealing that it was not hepatotoxic to broilers. Supplementation of W. somnifera to stressed birds reduced the stress related hyperglycemia and hypercholesterolemia. The increased level of C-reactive protein in stressed birds was reduced through supplementation of W. somnifera. Supplementation of W. somnifera increased the GSH and decreased LPO levels in birds. Supplementation of W. somnifera ameliorated the stress related oxidative damage through the reduction of LPO and increase of GSH levels. W. somnifera improved the immune status of normal birds as well as that of immunosuppressed stressed birds. Besides, it also improved the activities of gastrointestinal enzymes in normal and stressed birds.
