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.

    Characterisation and evaluation of indegenous ducks of Kerala
    (Department of Poultry Science, College of Veterinary and Animal Sciences, Mannuthy, 1997) Mahanta, J D; KAU; Ramakrishnan, A
    A basic study was conducted to characterise the two distinct indigenous types of ducks, namely Chara and Chemballi of Kerala and to evaluate their production potential. Five hundred sexed day-old female and 100 male ducklings each from Chara and Chemballi type were brought from M/s Susan Roy Hatchery of Chennithala. The ducklings were reared on deep litter system of management under identical conditions till 8 weeks of age. Thereafter they were switched over to semi- intensive system. The ducklings were wing banded and weighed individually at day-old, 4, 8, 12, 16, 20, 30, 40 and 52 weeks of age. After 18 weeks of age, 300.females and 30 males from each type were selected for further studies. The females from each type were divided into three groups of 100 birds each. At 18 weeks of age, ducklings were wing badged and provided with individual laying nests to facilitate recording of individual performance. Drakes of each type were maintained separately to study the external morphology and growth traits. At 20 weeks of age, individual body measurements and plumage colour patterns of different body parts of both Chara and Chemballi were recorded. The age at first egg (AFE) of all individual ducks, the weight of first egg, egg weight at 30, 40 and 50 weeks of age, shape index and shell colour of eggs, age at 5, 10 and 50 per cent egg production, total egg production upto 52 weeks of age, per cent duck-day and duck-housed egg production at eight 28-day laying periods and at weekly mean basis of the flocks were calculated and recorded. Morphologically, Chara and Chemballi drakes were squat in posture and gait and they differed in the colour of plumage of the head region. It was lustrous greenish black in Chara and dull greenish black in Chemballi. The Chara females were usually blackish brown in the back, tail and wing. The Chemballi females in general were brownish black and brownish grey in the back, tail and wings. The average body weights and growth pattern of Chara and Chemballi males were almost similar upto 52 weeks of age, whereas the Chara females tended to be heavier in body weights at all ages except 4 and 12 weeks. Significantly higher body weights at day-old and 20 weeks of age was recorded in Chara females over the Chemballi. The average age at first egg (AFE) in Chara and Chemballi was 148.59 and 147.50 days respectively. The ages at 5, 10 and 50 per cent egg production were 144, 153 and 187 days in Chara, while those in Chemballi were 141, 148 and 184 day respectively. The average egg number per duck upto 50 weeks of age was 116.09 in Chara and 124.95 in Chemballi. The corresponding mean per cent duck-day production in Chara and Chemballi was 44.49 and 48.68 respectively. The mean per cent duck-housed egg production to 50 weeks of age in Chara and Chemballi was 41.78 and 42.91 respectively. The mean weekly per cent egg production of Chara and Chemballi upto 52 weeks of age widely fluctuated from week to week. It was also found that during the production period upto 52 weeks of age there were two peaks in per cent egg production in both Chara and Chemballi type. The overall mean egg weight of Chara (69.69 g) was significantly (P<0.05) higher than that of Chemballi (68.08 g) . In the laying periods of Chara and Chemballi there were no discernible clutch size/pause. Broodiness as a trait was almost absent in both the types.

    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.
