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.

    Comparative study of ketamine hydrochloride and thiopentone sodium anaesthesia in birds
    (Department of Surgery, College of Veterinary and Animal Sciences, Mannuthy, 1991) Devanand, C B; KAU; Abraham Varkey, C
    The present study was undertaken to assess the efficacy of (i) ketamine hydrochloride, (ii) thiopentone sodium, and (iii) ketamine hydrochloride followed by thiopentone sodium, for anaesthetising domestic chicken and ducks. Th~rty apparently healthy White Leghorn cocks, aged 18 - 20 weeks and weighing 1.120 - 1.920 kg (Group I) and thirty apparently heal thy White Pekin .dz-ake s , aged 20 - 22 weeks and weighing 1.700 - 2.100 kg (Group II) were used. Group I and II were further divided into three sub-groups, viz.,A, Band C consisting of ten birds each. Ketamine hydrochloride at the rate of 100 mg per kg bodyweight was administered in sub-group A, thiopentone sodium (2.5 per cent solution) at the rate of 15 mg per kg in sub-group B, and ketamine hydrochloride at the rate of 50 mg per kg followed by thiopentone sodium (2.5 per cent solution) at the rate of 7.5 mg per kg in sub-group C, in both the trials. The drugs were administered intraperi- toneally. During the onset of anaesthesia, when ketamine hydrochloride was administered, loss of balance, unsteadiness of head, cyanosis of comb and wattles, defaecation and vocalisation were noticed in chicken, but in ducks defaecation was not present. Ruffled feathers, dropping of wings, fluttering and wagging of tail were noticed as additional symptoms in ducks. When thiopentone sodium was administered, loss of balance, unsteadiness of head, cyanosis of comb and wattles, ruffled feathers and dropping of' wings were noticed in chicken, but in ducks vocalisation and fluttering were noticed in addition. When ketamine hydrochloride followed by thiopentone sodium was administered, loss of balance, unsteadiness of head, cyanosis of comb and wattles, dropping of neck and wings, and closing of eyelids were noticed in chicken and ducks. In ducks the onset was very quick. All the birds assumed sternal recumbency followed by lateral recumbency after the onset of anaesthesia. As the effect of anaesthesia deepened, pedal reflexes were abolished in both the groups. However, other reflexes such as corneal, pupillary, palpebral and reflexes of the third eyelid, comb and wattles were persisting in chicken and ducks. During ketamine hydrochloride anaesthesia eyes were kept open, and when thiopentone sodium or ketamine hydrochloride followed by thiopentone sodium were administered, eyes were kept closed. In ducks, abolished when the reflexes of the third eyelid were ketamine hydrochloride followed by thiopentone sodium was administered. The induction was smooth and uneventful in chicken and ducks. The time for induction was 7.30+0.53 min.,. 9.30+0.38 min. and 8.00+0.58 min. in sub-groups A, Band C respectively in chicken, and 9.20±.0.58 min., 10.20+0.87 min. and 4.60+0.70 min. in sub-groups A, Band C respecti vely in ducks. The time for induction was the least in chicken when ketamine hydrochloride was used, and ln ducks when ketamine hydrochloride followed by thiopentone sodium was used. The duration of anaesthesia was 63.40+2.16 min., 31.40+1.82 min. and 40.20+3.99 min. in sub-groups A, Band C respectively in chicken, and 35.90±2.43 min., 18.90+0.99 min. and 20.20+0.89 min. in sub-groups A, Band C respectively in .du ck s , The duration of anaesthesia was maximum when ketamine hydrochloride was administered and minimum when thiopentone sodium was administered in both the groups. The duration of recovery was 135.50+9.24 min. in sub-group A, 149.60+8.32 mln. in sub~group B and 131.20+5.10 min. in . sub-group C, in chicken, and 84.50+7.31 min. in sub-group A, . 64.40+8.33 min. in sub-group Band 113.10+6.15 min. in sub-group C, in ducks. The duration of recovery was the least when ketamine hydrochloride followed by thiopentone sodium was used in chicken, and when thiopentone sodium was used in ducks. The recovery from anaesthesia was smooth and uneventful in both the groups. Vigorous shaking of the head was seen when ketamine hydrochloride was administered in ducks. There was reduction in cloacal temperature during anaesthesia. Respiration rate showed an initial rise followed by gradual reduction. The total erythrocyte count was decreased during anaesthesia. The total leukocyte count was decreased in sub-groups A and B, and increased in sub-group C, in chicken. There was an increase in total leukocyte count in ducks. Lymphocyte count was decreased, but heterophil count and eosinophil count were increased. There was no response to pain on incising and suturing the skin, muscles and peritoneum except for slight movement while incising the skin during ketamine hydrochloride anaesthesia. Focal congestion of liver and kidney were noticed on the 5th day. Mild degree of inflammatory reaction on the parietal peritoneum was noticed at the point of entry of the needle wherein thiopentone sodium was administered. From the results of present study, it could be found that intraperitoneal administration of ketamine hydrochloride, thiopentone sodium, and ketamine hydrochloride followed by thiopentone sodium resulted in satisfactory surgical plane of anaesthesia in chicken and ducks. For chicken, ketamine hydrochloride is preferred because of the comparatively least time for induction, prolonged duration of anaesthesia and recovery. Post anaesthetic complications were not found. In ducks the duration of anaesthesia was more, when ketamine hydrochloride was administered, but vigorous shaking of the head was seen during the period fr~v.ay. Hence, for ducks, ketamine hydrochloride followed by thiopentone sodium is preferred because of the comparatively least time for induction and satisfactory duration of anaesthesia and recovery.
