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.

    Chloral hydrate for general annaesthesia in goats
    (Department of Surgery, College of Veterinary and Animal Sciences,Mannuthy, 1981) Viswanathan, R; KAU; George, P O
    Thirtysix apparently healthy alpins – malabari cross- bred bucks aged from 17 to 30 months and weighing from 22 to 39.5 kg were used for the present study. They were divided into two groups viz., Group I and II, consisting of 18 animals in each. Each of these groups was further divided into three subgroups viz. A, B and C, consisting of six animals in each. Freshly prepared chloral hydrate six per cent solution was administered intravenously at the rate of 1.0, 1.5 and 2.0 ml per kg bodyweight, while triflupromazine hydrochloride (Siquil) at the rate of 0.2 mg per kg bodyweight was also administered intravenously as the premedicant , in group II. Following were the salient results obtained during the present study: When the dose of chloral hydrate was increased, 1) Disappearance of palpebral reflex was quicker and duration was longer, 2) Setting in of incoordination of movements was quicker and the time for assuming the normal gait was longer and 3) Recumbency was seen only in higher doses. Administration of triflupromazine hydrochloride (siquil) as premedicant , increased the efficiency of anaesthetic effect in these animals. Temperature variation consequent on the administration of chloral hydrate, with and without premedication , was not significant the variation being less than 10 P. There was an increase in the rate of respiration and pulse within five minutes of administration of the drug (s), which showed a gradual downward trend. There was reduction in the erythrocyte count, haemoglobin and packed cell volume, while there was slight increase in the leucocyte count. On the basis of the present study, intravenous administration of chloral hydrate, six per cent solution, at the rate of two ml per kg bodyweight, may be recommended in goats, for surgical procedures of about half an hour durations. Premedication with triflupromazine hydrochloride at the rate of 0.2 mg per kg bodyweight would give better results.,

    Studies on epidural anaesthesia in goats
    (Department of Surgery, College of Veterinary and Animal Sciences, Mannuthy, 1981) Sarada Amma, T; KAU; George, P B
    The present study was under taken with the object of finding out the effects of epidural administration of varying doses of lidocaine hydrocaine hydrochloride two per cent solution with and without the addition of hyaluronidase in goates. Epidural injection was given at the lumbosacral site using the Brooks’ epidural needle directed perpendicularly downwards. Thirty – six apparently healthy Alpine – Malabari crossbred bucks aged six to fifteen months and weighing seven to twenty – two kilograms were used for the study. The animals were divided into two groups viz., Group 1 and Group 11, each consisting of 18 animals. In Group 1, lidocaine hydrochloride at the rate of 4 mg, 8 mg and 16 mg/kg body – weight was administered as two per cent solution in three Subgroups each consisting of six animals. Similarly in Group 11, lidocaine hydrochloride was administered as two per cent solution along with hyaluronidase (150 I.U./100 ml of lidocaine hydrochloride solution) in three Subgroup each consisting of six animals. Significant positive correlation was noticed between the depth of insertion of the epidural needle and body – weight of the animals. When the dose of lidocaine hydrochloride was increased, there was proportionate decrease in the time of onset and increase in the duration of anaesthesia. In the same dose level when hyaluronidase was added there was further reduction in the time of onset, but the duration of anaesthesia was decreased. On statistical analysis of the data, no significant difference could be seen between 1) the time of onset of flaccidity of tail and relaxation of anal sphincter 2) the duration of flaccidity of tail and relaxation of anal sphincter and 3) the time taken for assuming sternal recumbency and complete relaxation of the muscles of hind – limbs. At a dose of 4 mg/kg body – weight in both the groups, the extent of analgesia was found to be the same, irrespective of addition of hyaluronidase. At higher doses (8 mg and 16 mg/kg body – weight), the extent of analgesia was found to be more. But when hyaluronidase was added, the extent of analgesia was still further increased. ‘Dog sitting posture’ was observed during the onset of anaesthesia only at a dose of 4 mg/kg body – weight. The animals got up only when flaccidity of tail and relaxation of anal sphincter disappeared. At the dose of 4 mg and 8 mg/kg body – weight there were no untoward reactions. But at the dose of 16 mg/kg body – weight lacrimation, salivation, protrusion of tongue, locked jaw, stiffness of head and neck, pedalling movements with the fore – limbs, opisthotonos and dyspnoea were observed in some of the animals during the onset of anaesthesia. Recovery phase was uneventful in all the animals, at all the dose levels. Transient unilateral or bilateral hind – leg lameness, dullness and anorexia were noticed in some of the animals as a post – anaesthetic complication. Epidural injection of lidocaine hydrochloride, two per cent solution at the rate of 4 mg/kg body – weight is recommended for surgical operations of the hind – quarters and inguinal region, while 8 mg/kg body – weight is recommended for operations on the flank region. Hyaluronidase may be added for getting quicker onset and greater extent of analgesia.

    Treatment of fracture of tibia in calves and its radiographic evaluation
    (Department of Surgery, College of Veterinary and Animal Sciences, Mannuthy, 1981) Ayyappan, K R; KAU; George, P O
    The present study was conducted on 16 apparently healthy cross – bred bull calves aged from six to nine months and weighing 38 to 75 kg. They were divided into two groups, viz: Group 1 consisting of six animals; and Group 11 consisting of 10 animals. Under chloral nacrosis and epidural anaesthesia, fracture of tibia was created either on the middle or at the lower third after incising the skin medially and sawing the tibia with a wire saw. In Group 1, the skin wound was sutured, fracture reduced and plaster cast applied. Enteromycetin was administered intramuscularly. None of the animals could bear weight on the fractured limb. Wound infection and abscess formation was apparent. Though reduction was proper initially, the fragments showed displacement later. Subsequent radiographs did not show any progressive osteogenic reaction and in none of the animals clinical union was noticed. In Group 11, Kuentscher Cloverleaf nail was directed into the medullary canal with the help of the guide wire and was anchored into the distal fragment. The wound was sutured and plaster of paris cast was applied as an additional support. Excepting two animals, the rest could bear weight by the 10th to 30th day. Streptopenicillin or Munomycin was first administered. This was later followed by a course of Chloramphaenicol after sensitivity test of the pus. Periosteal proliferation was apparent on either fragments by third to fifth week which became more prominent by the fifth to sixth week. Lipping of the fracture edges, obliteration of the fracture line and the formation of the callus were observed by the seventh to eighth week. Later, organisation of the callus took place. Of the ten cases, clinical union had taken place in six animals as evidenced by the dense callus in radiographs. In other cases extension of the local infection into the medullary canal had resulted in non – union of fracture even though osteogenic reaction was in progress inspite of the infection. From the results of the present study it is seen that, (1) Internal fixation using Kuentscher Cloverleaf nail supported by plaster cast and administration of antibiotics would be a satisfactory technique, and (2) reduction followed by immobilisation with plaster cast alone will not be satisfactory in the treatment of tibial fractures in calves.
