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.

    Requirements of protein and energy for broilers during summer season
    (Department of Poultry Science, College of Veterinary and Animal Sciences, Mannuthy, 1992) Amritha Viswanath; KAU; Ramakrishnan, A
    An experiment was designed and conducted to establish the requirements of protein and energy for broilers during the summer season in the hot and humid atmosphere of Kerala. Four trials were conducted in a span of two years. In each trial the following energy-protein combinations at starter, and subsequent finisher diets were tested in a completely randomised design. Treatment Starter Finisher Diet 1 22% CP:2900 Kcal ME/kg 19% CP:3000 Kcal ME/kg Diet 2 24% CP:2900 Kcal ME/kg 19% CP:2900 Kcal ME/kg Diet 3 26% CP:2900 Kcal ME/kg 19% CP:3000 Kcal ME/kg Diet 4 26% CP:2900 Kcal ME/kg 19% CP:2900 Kcal ME/kg Trials corresponding to the same period for the two years were pooled and the results were presented as Period A (started in early summer and ended in peak summer) and Period B (started in peak summer and ended in late summer). Except for the difference in nutrient intake, all the management practices followed were uniform for the differenttrials and treatment groups. Feed and water were given ad lib. The chicks were fed with starter diet upto six weeks of age and finisher diet upto eighth week of age. Results of the study revealed that body weight at eighth week of age was not influenced by different- energy protein levels in the diet during both Period A and Period B. But difference between periods was statistically (P < 0.01) significant. Broiler chicks reared during Period A showed significantly lower mean body weight at eight week than Period., B. Dietary combination of 22:2900 in the starter and 19:3000 in the finisher stage upto eight weeks of age was found to be optimum for growth of broilers in summer months in Kerala. Body weight gain was not influenced by the dietary. treatments and by periods upto sixth week of age. Thereafter body weight gain was influenced by season. Broiler chicks reared during Period B showed higher body weight gain than Period A. Maximum body weight gain was recorded at fifth week of age in both Period A and Period B. Feed consumption was not affected by dietary treatments in both Period A and Period B, but was significantly affected by periods at seventh and eighth week of age. Feed efficiency was also not affected by different dietary treatments upto eight weeks of age. Broiler chicks reared during Period A showed poorer feed efficiency from sixth week onwards.

    Dietary protein and energy requirements of ducks for growth
    (Department of Poultry Science, College of Veterinary and Animal Sciences, Mannuthy, 1991) Peethambaran, P A; KAU; Ramakrishnan, A (Guide)
    A detailed study was undertaken to establish the dietary protein and energy requirements of ducks for growth and also to ascertain the optimum age at slaughter in white pekin ducks. An attempt was made to study the general trend of growth in pekin ducks fed with different levels of protein and energy. An exhaustive review of literature has been presented on the effects of dietary protein and energy levels on growth and associated traits in pekin ducks. Five hundred and four (504) one-day old ducklings of white pekin breed were used for the study. Two feeding trials each for a period of ten weeks were carried out using nine experimental diets containing three levels of protein (17,20 and 23 per cent) and three levels of metabolisable energy (2400, 2600 and 2800 K Cal ME/kg). In each trial, the diets were fed to nine groups consisting of 28 ducklings in four replicates of seven ducklings each. The effects of protein and energy on production traits revealed the following: The requirements of dietary protein for optimum growth of white pekin ducks were 23 per cent until third week, 20 per from fourth to sixth week and 17 per cent from seventh to tenth week of age. The metabolisable energy requirement for optimum growth was proved to be 2400 K cal ME/kg diet from day-old to ten week of age throughout. The weekly body weights of ducklings receiving 20 and 23 per cent protein were significantly better until sixth week. Even though, ducklings receiving 17 per cent dietary protein were significantly lighter until sixth week, they recouped body weights by compensatory growth from seventh week onwards. The ducklings receiving dietary energy level 2600 K cal ME/kg have shown significantly higher weight gain and live body weight at first week. The second and third week gains and body weights were significantly higher in ducklings receiving 2400 and 2600 K cal ME/kg diet. The ducklings receiving 2800 K cal ME/kg showed significantly lower body weights and gains until third week. The weekly gains and body weights at sixth week were statistically comparable among the three energy levels studied. Rapid growth at early ages with 20 and 23 per cent protein was observed until fourth week. The growth was slow with 17 per cent level and peak gain occurred at fifth week. Protein x energy interaction effects on weekly body weights were non-significant. The interaction effects were significant in respect of sixth week weight gains, and feed intake at first week, fifth and sixth week of age. The feed intake at second and third week showed significant increase with increasing levels of protein. The energy level 2800 K acl ME/kg diet reduced feed intake markedly until third week. The cumulative feed intake at tenth week ranged from 7.879 to 9.423 kg per duckling, among experimental diets. The weekly feed-gain rations and cumulative feed efficiencies revealed poor conversion rates beyond eighth week of age. The cumulative efficiencies at sixth week were 3.2, 3.3 and 3.4 with protein levels 17, 20 and 23 per cent respectively. The ready-to-cook yield at fifth, eight and tenth week were 66.39, 68.76 and 69.69 per cent respectively. The processing yields and losses, serum protein and haemoglobin levels; and the moisture, crude protein and ether extractives in liver and thigh meat were not significantly influenced by dietary protein and energy levels, and ages at slaughter. The marketing age in pekin duck was found optimum at sixth week on the basis of live body weight, feed conversion efficiencies and economics. Based on the above findings it was concluded that white pekin ducks require 20 per cent protein and 2400 K cal ME/kg diet until sixth week of age. In this study, the highest margin of return over feeding cost recorded with the above diet was Rs. 10.11 per duckling, at sixth week. Therefore, age for marketing pekin ducks was found ideal at sixth week on feeding medium level of protein with low energy density diet.
