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.

    Studies on the nutrient requirements of kids
    (Department of Animal Nutrition, College of Veterinary and Animal Sciences, Mannuthy, 1979) Mercy, A D; KAU; Sivaraman, E
    An investigation was carried out to find out the nutrient requirements for optimum growth in kids. Twenty four Alpine – Malabari crossbred kids of 3 4 months of age formed the experimental subjects for the study. The animals, divided into three identical groups (groups 1, 11 and 111), were maintained on three different levels of nutrient intake for over a total period of 4 ½ months, the parameters recorded during the course of the study being average daily body weight gain, drymatter intake, feed conversion efficiency, digestibility coefficients of nutrients, nitrogen balance, mineral balance and haematological constituents. The average daily gain and feed conversion efficiency recorded for animals in the three groups 1, 11 and 111 were found to be 63.7 + 5.3, 64.4 + 5.0 and 67.6 + 2.0 g and 7.0 + 0.7, 7.5 + 0.5 and 7.9 + 0.3 respectively. The average drymatter consumption of animals were 3.1 + 0.2, 3.5 + 0.3 and 3.6 + 0.3 kg per 100 kg body weight respectively for the three groups 1, 11 and 111. The data collected for the haematological constituents were found to lies within the normal range for the species indicating that all the animals under the three dietary regimes were maintaining normal and sound nutritional status. The requirements arrived at for protein and energy for unit gain in body weight were 0.86 + 0.06 0.90 + 0.06 and 0.89 + 0.03 kg D. C. P. and 4.84 + 0.4, 5.20 + 0.30 and 5.31 + 0.19 kg T. D. N. for the animals in groups 1, 11 and 111 respectively. The requirements of D. C. P., T.D. N., calcium and Phosphorus arrived at from the results obtained during the course of the experiment are considered optimum for normal growth in Alpine – Malabari crossbred kids.

    Studies on the nutritional requirements of the Indian elephant
    (Department of Nutrition, College of Veterinary and Animal Sciences, Mannuthy, 1979) Ananthasubramaniam, C R; KAU; Chandra, Menon K
    Stimulated by the results of a digestion trial conducted previously in growing and adolescent elephants, an investigation involving, nitrogen, calcium, phosphorus and energy balance studies was carried out in two young and two adult elephants fed palm leaf ad lib. at first (Trial 1) and subsequently at 75 per cent of the ad lib. in take (Trial 11) with a view to evolve feeding standards for the elephant for maintenance and growth. Prior to this investigation, the reliability of applying a formula based on body measurements to predict body weights of the elephants as accurately as possible for purposes of their scientific feeding and judicious treatment was examined in 20 animals of varying age, sex and weight. The nutritional status of the elephants under balance trials was assessed in terms of concentrations of some of the well – known blood constituents. From the overall results obtained, the salient inferences drawn were the following : 1. For predicting the body weights of the elephants, formulae devised on the basis of chest girth and neck girth measurements are found to be more accurate than those involving body length, height and chest girth. 2. Adult animals, whether fed palm leaf ad lib. or at restricted level, consume more feed and more dry matter and void more dung dry matter and total urinary solids, as compared with the young elephants under identical conditions. 3. Adult animals digest dry matter, crude protein and nitrogen – free – extract better than the young at both levels of intake, the differences between them in the digestibility of dry matter on restricted level of intake being significant (P < 0.05). Restriction of feed intake significantly reduces the digestibility of nitrogen – free – extract (P < 0.05) in young animals. 4. Adult animals consume daily more DCP and TDN as compared with the young animals at both levels of intake. Restricted feeding reduces the DCP and TDN intakes of both the adult and young animals, the TDN intakes per metabolic body size of both groups being significantly less than the same observed during ad lib. feeding (P , 0.01). The adult animals consume significantly more TDN as compared with the young on restricted feeding (P < 0.05). 5. The overall differences in nitrogen balance between the two groups and between the two trials are significant (P < 0.05). Adult animals register higher values for positive nitrogen balance as compared with the young on both levels of feeding. Restricted feeding reduces the nitrogen balances in both the groups. 6. Adult animals show significantly higher calcium balance as compared with the young on restricted level of feeding (P < 0.05). Between the two levels of intake, significant difference is observed in the case of the young (P < 0.05), the animals showing batter calcium balance on ad lib. feeding. 7. All animals, irrespective of group or level of intake, show negative balance for phosphorus. 8. Adult animals consume and digest gross energy better than the young in both the trials, the increase in the availability of digested energy per metabolic body size in the case of the adult animals in each trial being significant (P < 0.05). Restriction of feed intake significantly reduces the digested energy values in the case of both the groups (P < 0.01). 9. Dry matter, DCP, TDN, DE and ME requirements for the maintenance of the adult elephant are : 108g, 6g, 58g, 278 kcal and 237 kcal respectively per unit metabolic body size (kg.73) per day. 10. Dry matter, DCP, TDN, DE and ME requirements for the growth of the young elephant are : 142g, 7g, 335 kcal and 279 kcal respectively per unit metabolic body size (kg.73) per day. 11. The requirements of calcium for the maintenance and growth of the elephant are: 0.5g and 0.6g respectively per unit metabolic body size (kg.73) per day. 12. Palm leaf even when fed ad lib. does not supply enough phosphorus either maintenance or for growth. 13. Palm leaf even when fed at a restricted level provides adequate cobalt for Vitamin B12 synthesis and for other physiological purposes. 14. Feeding standards for the maintenance and growth of the elephant are formulated in terms of Dry matter, DCP, TDN, DE and ME values. 15. The concentrations of Vitamin B12 in blood plasma of the adult and young elephants are found to be on an average 18.05 and 16.94/ug/100 ml respectively. 16. Adult and young elephants fed palm leaf maintain sound nutritional status, adjudged from haematological values. The significance of the above inferences is discussed briefly. Summary of summary 1. Two formulae based on neck girth and chest girth measurements have been devised to predict the body weights of the elephants to 97 per cent accuracy. 2. It has been shown that whenever palm leaf forms the sole source of feed for the elephant, there is a need for a phosphorus supplement. 3. Feeding standards in terms of Dry matter, DCP, TDN, DE and ME for the maintenance and growth of the elephant have been evolved and recommended in the form of formulae. 4. The level of Vitamin B12 in the blood of the elephant has been reported for the first time.

    Evaluation of feeding value of rubber seed cake for promoting growth in calves
    (Department of Nutrition, College of Veterinary and Animal Sciences, Mannuthy, 1977) Viswanathan, T V; KAU; Ananthasubramaniam, C R
    A detailed investigation was carried out to assess the value of rubber seed cake as an ingredient in the concentrate mixture of calves to study the growth rate, nutriture, feed efficiency and economics of rearing. Twenty four, Jersey x Sindhi cross – bred calves of 8 – 14 months of age belonging to the University Livestock Farm, Mannuthy were divided into three equal groups and distributed under three dietary treatments, T1, T2 and T3, the animals being fed concentrate mixtures containing 0, 15 and 30 per cent levels of rubber seed cake respectively for a period of six months. Paddy straw served as the sole roughage. Rubber seed cake at 30 per cent level promoted better weight gains, body size and feed efficiency. Incorporation of rubber seed cake in the concentrate mixture improved the digestibility coefficients of nutrients as also the balance of nitrogen, calcium and phosphorus in the animals. Animals fed rubber seed cake maintained perfect health as evidenced from their haematological values and were free from any toxic effect as adjudged from the histopathological examination of the internal organs and their carcass quality. The cost of feed was found to be 14 per cent lower for kg body weight gain when rubber seed cake was incorporated at 30 per cent level in the concentrate mixture of growing calves. The overall results obtained during the course of the present investigation indicate that rubber seed cake can be incorporated in the concentrate mixture for growing calves at 30 per cent level to achieve both biological and economic efficiency.
