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.

    Effect of dietry iron and supplementation of phytase on growth and mineral availability in broiler chicken
    (Department of Animal Nutrition, College of Veterinary and Animal Sciences, Mannuthy, 2004) Anup Kollanoor, J; KAU; Syam Mohan, K M
    An investigation over a period of eight weeks was carried out to study the effect of dietary iron and supplementation of phytase on growth and mineral availability in broiler chicken. One hundred and ninety two day-old broiler chicks (Ven cob) were divided into four identical groups having four replicates in each group with 12 birds in each replicate and allotted randomly into four dietary treatments viz., T1, T2, T3 and T4. The treatments consisted of a standard broiler ration (T1) containing mineral mixture as per BIS (1992), ration containing mineral mixture without iron (T2), ration containing mineral mixture with iron and supplemental phytase at 750 U/kg diet (T3) and ration containing mineral mixture without iron and supplemental phytase at 750 U/kg diet (T4). Performance parameters such as body weight, weight gain, dry matter consumption, feed efficiency, protein efficiency, tibial weight and tibial ash did not differ significantly between the groups. Significant increase (P<0.05) in the availability of phosphorus with marginal increase in the availability of Fe, Cu and Ca were observed for the groups fed T2 and T3 diets, when compared to other groups. Increased retention of iron in liver of birds fed T2, T3 and T4 diets were observed showing significant difference (P<0.05) with birds fed control diet T1. But the iron retention in spleen did not differ between treatments at sixth and eighth weeks of age. Overall evaluation of the results of the present study reveals that supplementation of inorganic iron through mineral mixtures over and above ingredient iron leads to interaction between Fe and other minerals especially P and Cu. Inclusion of phytase, even though did marginally improve iron retention in storage organs, it did not create significant improvement when added to diets without supplementation of inorganic iron. So it is concluded that levels of 620 to 660 ppm Fe from the ingredients satisfies the requirement for growth, mineral availability and retention in broilers.
