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.

    Optimum energy and protein requirements of broiler rabbits
    (Department of Nutrition, College of Veterinary and Animal Sciences, Mannuthy, 1995) Ganga Devi, P; KAU; James, C S
    A detailed investigation involving two series of growth studies spread over a period of 24 weeks in Soviet Chinchilla and Cross Bred rabbits was carried out to establish the optimum energy and protein requirements for growth and to ascertain the optimum age for economic slaughter. One hundred and eight weanling Soviet Chinchilla and 108 weanling cross bred (SC X NZW) rabbits formed the experimental subjects. Rabbits of each breed were divided into nine identical groups and maintained factorially on three levels of crude protein (CP) viz., 12, 16 and 20 per cent and digestible energy viz., 2000, 2500 and 3000 kcal/kg for over a period of 168 days involving metabolism and slaughter studies during 8th, 16th and 24th week of experiment and production traits along with associated characters were studied and the salient results are presented. Rabbits maintained on different energy protein combinations showed significant difference in growth rate (P <0.01). Both dietary energy and crude protein were found to influence the average daily gain. The highest rate of gain was achieved in animals maintained on ration containing comparatively higher DE and CP while lowest rate of gain was noticed in animals maintained on low energy, low protein diet. On further scrutiny of the data, an appreciably better and identical growth response was observed in animals maintained on ration containing 3000 kcal DE/kg with 16 per cent CP and ration containing 2500 kcal DE/kg with 20 per cent CP in both pure bred and cross bred rabbits. It is also noticed that for maximum growth rate a ration containing 2500 kcal. DE/kg need be sufficient as further increase in DE have not evinced any better response on ADG, which supports the view that for optimum biological response, a ration containing 2500 kcal DE/kg is sufficient for both pure bred and cross bred rabbits. As between the periods it was observed that the animals attained maximum ADG during the first 56 days of experiment and there after ADG gradually declines irrespective of the level of CP or DE in the ration. Both dietary energy and crude protein significantly influenced (P <0.01) the feed conversion efficiency of animals. Highest efficiency of feed conversion was noticed in rabbits maintained on Ration D containing 2500 kcal DE/kg and 20 per cent CP the values being 9.27 in SC and 8.85 in CB rabbits and further increase in DE from 2500 kcal/kg to the extent of 3000 kcal/kg did not contribute better feed efficiency. Data on feed efficiency further revealed that maximum efficiency was observed during the first eight weeks after weaning and there after there is a linear reduction in feed efficiency as the age advances, in all the nine dietary treatments. With regard to cost of production the maximum biological and economical efficiency could be observed in animals maintained on ration containing 2500 kcal DE/kg with 20 per cent CP and when the cost of production was evaluated in between the periods viz., 0-56 days, 56-112 days and 112-168 days, the cost efficiency is seen maximum during 0-56 days of experiment. Dry matter intake on percentage of body weight was found decreasing on increasing the dietary energy level. Haematological values were with in the normal range and were not significantly influenced by the dietary energy and protein levels. Digestibility of nutrients and percentage retention of nitrogen, calcium and phosphorus were significantly influenced by the dietary treatments with an increasing trend on increasing the dietary energy and protein level. From the metabolism studies carried out during 8th, 16th and 24th week of experiment, the percentage retention of nitrogen, calcium and phosphorus were found reduced on advancing the age of animals. Slaughter studies conducted at 8th, 16th and 24th week of experiment revealed that dressing percentage is directly proportional to the pre-slaughter weight of the animals. Higher dressing percentage is recorded in animals having higher body weight and vice-versa. Carcass yield were higher at 16th and 24th week of experiment than that at eighth week of experiment.
