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 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.

    Studies on vesico-colostomy and vesico-rectostomy in dogs
    (Department of Surgery, College of Veterinary and Animal Sciences, Mannuthy, 1975) Sarada Amma, T; KAU; Venugopal, A
    Vesico-colostomy and vesico –rectostomy as methods of urinary diversion in dogs and cats had been reported. The following experiments were undertaken to assess the relative efficacy of either of these techniques. Surgery was performed in two groups of dogs. Under genral anaesthesia, after laparotomy, in the vesico-colostomy group, the fundus of the bladder was anastomosed to the terminal part of descending colon; and in vesico-rectostomy group, the neck of the bladder was anastomosed to the anterior part of rectum. In addition to general observations, the postoperative changes in haemoglobin content, leucocyte count, and blood urea nitrogen level were also recorded and are compared to the preoperative levels. Their clinical significance was also assessed. The experimental dogs acquired physiological control over micturition through the anus within three to four days and there was no soiling of the perineum, though no indwelling catcheter was used. The animals were kept under observation for a period up to four weeks and were later sacrificed. Two of the four dogs in vesico-colostomy group was in apparent good health after surgery. Of the other two, one animal died on the 17th day and autopsy revealed nephritis of the left kidney. The other died on the 22nd day and in it the ostium was seen to be closed completely by scar tissue. In the vesico- rectostomy group, three of the four dogs were in apparent good health. One dog in the group showed symptoms of uraemia and died on the 11th day but no abnormally at the level of anastomosis could be detected at autopsy. Haematological studies, in animals of both the groups did not reveal any significant changes except in one dog which had uraemia. Intravenous pyelography after one month, in 2 dogs of vesico-rectostomy group, revealed normal kidney function and emptying of the bladder. At autopsy the areas of anastomoses were studied (grossly and histopathologically) and urine samples were cultured to check up infection. E.coli, streptococci, staphylococci and certain gram negative organisms were isolated from the urine samples collected at autopsy in all animals. In the vesico- rectostomy group the ostium was well established and patent in all animals. In the vesico – colostomy group, there was constriction of ostium in one and in another the ostium was completely closed by scar tissue formation; but the remaining cases were apparently normal. Histopathological examination of bladder, colon and rectum revealed complete healing of the corresponding layers of tissues at the site of anastomosis in the successful cases of either group. Mild cystitis was observed at postmortem in three animals, one in Group I and two animals in Group II. There was faecal regurgitation into the bladder in three cases one from Group I and two from Group II. It is concluded that either vesico-colostomy or vesico-rectostomy could be adopted as urinary diversion technique in dogs; but vesico – rectostomy appeared to be more desirable than vesico – colostomy.
