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.

    Tracheal reconstruction in dogs under acepromazine - thiopental anaesthesia
    (Department of Surgery, College of Veterinary and Animal Sciences, Mannuthy, 1995) Angamuthu, Jayasudha; KAU; Ravindran Nayar, S
    The experiment was conducted on twelve, apparently healthy, adult, nondescript dogs of either sex, divided into two groups, viz., Group 1 and Group 11, each consisting of six animals. Circumferential resection of two adjacent tracheal rings of the cervical trachea was performed and the trachea was reconstructed by end – to – end anastomosis in the animals of Group 1 and with Marlex mesh prosthesis in the animals of Group 11. All the animals were premedicated with acepromazine maleate IM, and anaesthesia was induced by 2.5 per cent solution of thiopentone sodium IV. Induction of anaesthesia was complete by 3.26 + 0.10 minutes, duration of surgical anaesthesia was 65.00 + 3.29 minutes and time for recovery was 192.91 + 13.68 minutes. Variation in the physiological and haematological parameters during anaesthesia were not significant. In Group 1, all the animals had normal respiratory function throughout the period of observation, following surgery. In Group 11, all the animals, except one, developed severe complications and died within one to four weeks postoperatively. Only one dog survived in this group and was sacrificed on the 45th postoperative day. During the postoperative period, the rectal temperature did not show marked variations in both the groups. The pulse and respiration rates showed an initial increase in Group 1. However in Group 11, marked decrease in pulse rate and increase in respiration rate was noticed. Hemogram on the different postoperative days showed an increase in the total leucocyte count in both the groups, and increase in monocyte and eosinophil count in Group 11. Radiography on different postoperative days in Group 1 demonstrated that there was no reduction in the size of the tracheal lumen at the site of anastomosis in five of the six animals. In Group 11, radiography revealed a progressive reduction in the size of the tracheal lumen at the site of reconstruction in four animals, and only slight reduction in one dog on the 45th postoperative day. At autopsy, gross examination of the trachea at the site of anastomosis in Group 1 showed mild to moderate adhesions to the adjacent tissue and there was no reduction in the size of the tracheal lumen in five of the six dogs of this group. In animals of Group 11, dense adhesion between the site of reconstruction and adjacent tissue was observed. The mesh was fully incorporated at the site of reconstruction in five of the six animals. One animal had shown anastomotic dehiscence. Almost complete occlusion of the trachea by overgrowth of tissue was observed in four animals and slight reduction in the tracheal lumen in one animal. Histopathology at the site of anastomosis in Group 1 revealed complete healing of all the layers of the trachea by the 30th postoperative day. In Group 11, tracheal stenosis was associated with ingrowth of granulation tissue in four animals. The mesh was infiltrated by fibrous tissue in five of the six animals. Epithelium was seen lining the prosthesis on the 45th postoperative day.

    Comparison of crushing and modified gambee techniques for intestinal anastomosis in dogs under xylazine anaesthesia
    (Department of Surgery, College of Veterinary and Animal Science, Mannuthy, 1995) Venkatesan, C; KAU; Abraham Varkey, C
    The study was conducted on 12 apparently healthy, adult mongrel dogs of either sex, dived in to two groups viz, group I and group II, each consisting of 6 dogs. All the animals were pre-mediacated with diazepam at the rate of 1 mg/kg bodyweight intravenous and anaesthetized with intramascular administration of xylazine hydrochloride at the rate of 2 mg/kg bodyweight. In the animals of group I and to end intestinal anaestomosis was performed with crushing pattern of suturing and in the animals of group II end to end intestinal anastomosis was performed with modified Gambee pattern of suturing. The anesthetic technique was satisfactory for the surgical procedure in all the animals . The induction tome for anaesthesia was 15.50 + 1.00 minutes. THe anaesthetic effect persisted for about 48.25-1.10 minutes. The abdominal muscle relaxation and analgesic effect were found satisfactory. The recovery period was 30.00 + 1.50 minutes and was smooth and uneventful. The time required to perform anastomosis using crushing and modified gambee techniques were 26.30 + 1.40 and 35.70 + 0.87 respectively. The average number of sutures used in both techniques were 15. In both groups, animals well tolerated food in the immediate post-operative days. However, one animal in group I and three animals from group II, had vomition immediately after consumption of milk at 12 hours post – operatively. Physiological and haemotological parameters did not reveal any significant variation. In both the groups , post operative lateral and ventrodorsal radiographs showed free passage of contrast medium (Barium Sulphate) upto the terminal colon. There was no evidence of anastomotic leakage and proximal distension in both the groups. Autopsy findings revealed that all the animals had adhesion at the anastomotic site with omentum. Adhesion to adjacent intestinal serosal surface were observed in one animal in each group . Gross evaluation of the adominal cavity revealed a low-grade peritonitis in one animal of group I on 3rd post surgical day. The Luminal stenosis of the anastomotic site revealed, maximum luminal stenosis (47.83%) at 7th post –operative days and minimum (21.74%) at 28th day following crushing pattern. In modified Gambee pattern, the maximum luminal stenosis (42.85%) was noticed at 5th and 7th post –operative days and minimum stenosis (7.32%) at 28th day. The luminal stenosis did not produce any clinical symptom in any of the dogs in both the groups. Angiograms of early post – operative day (5th day) showed diffused, avascular zone at the anastomotic site in both the techniques. Eventhourgh, there was commencement of proliferation of vessels and its invasion into anastomotic site by 14th day in the crushing anastomosis, normal vascularity and its crossing over could not be observed till 28th day, where as the modified gambee anastomosis showed proliferation and crossing over of fine arterioles by 28th day. Histological examination demonstrated that in crushing anastomosis comparatively moderate inflammatory reaction with predominance of mononuclears and few polymorphs on the 3rd day, but from 14th day there was only mild inflammatory reaction which which persisted upto 28th day. In modified Gambee technique, only mild reaction was seen on the early post opestive days and it subsided by 21st day. Rapid regeneration of epithelium was noticed in the modified Gambee (7th day) than the crushing technique. On the 28th day, in both the techniques all layers appeared in good apposition with proliferation of connective tissue on the muscular, subserosal and submucosal layers.
