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 microbial phytase on nutrient utilization in broilers
    (Department of Poultry Science, College of Veterinary and Animal Sciences, Mannuthy, 2000) Balasubramanian, D; KAU; Jalaludeen, A
    An eight week feeding trial using 180 day-old broiler chicks was conducted to study the influence of phytase supplementation (Natuphos''^-5000) on nutrient utilization and subsequent performance. Treatments involved a standard broiler diet, a low available phosphorus (LAP) diet and the low available phosphorus diet plus graded levels of phytase at the rate of 500, 750 and 1000 units / kg diet. The groups fed standard broiler diet and low available phosphorus diets supplemented with 750 and 1000 units phytase showed significantly (P<0.01) higher body weight and weight gain. The cumulative feed intake was statistically comparable among the experimental diets at sixth week, whereas, at eighth week it was significantly (P<0.05) lower in LAP diet without phytase than that of other diets. The feed conversion ratio was significantly (P<0.01) improved by the addition of phytase at 750 and 1000 units / kg in comparison to low available phosphorus diet. Graded levels of phytase addition linearly improved nitrogen retention while energy retention was significantly (P<0.01) higher in groups fed 750 and 1000 units of phytase / kg. The addition of 750 and 1000 units of phytase / kg diet significantly (P<0.01) increased the availability of calcium while phosphorus availability was improved by all levels of enzyme 500, 750 and 1000 units / kg. The excretion of phosphorus was significantly (P<0.01) reduced in enzyme supplemented groups. The availability of manganese and zinc was significantly more in enzyme supplemented groups. Tibial ash, serum calcium and serum inorganic phosphorus were significantly (P<0.01) increased by the addition of 750 and 1000 units of dietary phytase / kg both at sixth and eighth week of age. The serum alkaline phosphatase level was significantly (PO.Ol) decreased in the diets supplemented with phytase. Supplementation of phytase had no effect on per cent dressed yield and giblet yield. The per cent R-to-C yield was significantly (P<0.05) higher in groups fed standard diet, LAP diet and 500 units phytase supplemented diet at sixth week. Whereas at eighth week it was significantly (P<0.05) higher in groups fed standard diet and 1000 units phytase added diet. The livability was not influenced by dietary phytase and available phosphorus levels. The net profit per kg live weight at eighth week was 29, 94 and 85 paise higher in groups fed 500, 750 and 1000 units of phytase, respectively in comparison to LAP diet. The results suggested that supplementation of 750 units of phytase per kg in low available phosphorus diets is advantageous for commercial broiler chicken production.
