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.

    Assessment of the antifertility property of ocimum sanctum
    (Department of Pharmacology and Toxicology, College of Veterinary and Animal Sciences, Mannuthy, 1979) Girisdan, K; KAU; Jacob Cheeran, V
    A study was carried out in rats, to assess the antifertility property of the benzene fraction of the leaves of the plant Ocimum sanctum. Premating treatment was done in female animals at does levels of 200 and 400 mg per kilogram body weight for a duration of eight days. Male animals were subjected to the treatment at a dose level of 200 mg per kilogram body weight for 20 days . The experimental animals were allowed to mate with untreated animals of the opposite sex. Histopathological examination of the organs – pituitary, ovary, tests, liver and kidney were carried out. Results of the study suggested considerable reduction of fertility in both the sexes. This can be attributed to the impaired release of gonadotrophic hormones and the resulting improper functioning of the gonads. Administration of the extract showed no toxic effects in the treated rats as well as in their offspring.

    Studies on the Effect of Corticosteroids, Neostigmine and Calcium in Cobra Venom (Naja naja) Intoxication
    (Department of Veterinary Pharmacology and Toxicology,College of Veterinary and Animal Sciences, Mannuthy, 1975) Venugopalan, K; KAU; Nair, K P D
    Administration of specific antiserum as early as possible after snake bite is of utmost importance for better chances of survival. Supportive measures are definitely capable of reducing the venom toxicity And prolonging survival period eg., if the absorption of venom from the site of bite could be delayed or retarded it will be highly beneficial to the patient. It has been shown that certain drugs are capable of decreasing capillary permeability and altering the rate of absorption of venom from the site while other agents may alleviate neurotoxicity or reduce haemotoxicity of venoms on the system. The present study was undertaken to evaluate the beneficial effect of (1) ‘Betnesol’ (Glaxo brand of betamethasone), (2) Neostigmine bromide (E Merck) and (3) Calcium gluconate – 10% (Sandoz) in experimental envenomation with cobra venom (Naja naja) in adult rats of both sexes. One LD50 cobra venom (0.097 mg per 100 g body weight – death within 8 hours) was given intramuscularly to these experimental rats and the trial drugs viz., ‘Betnesol’ (0.6, 0.8 and 1 mg per 100 g body weight), neostigmine bromide (30 mcg per 100 g body weight) and calcium gluconate (8,10 and 12 mg per 100 g body weight) were given intraperitoneally at varying intervals to evaluate the efficacy to these drugs in respect of their ability to prolong the survival period of experimentally envenomated rats. It is observed that ‘Betnesol’ at dose rate of 0.8 to 1 mg per 100 g body weight of rate when given immediately after injection of one LD50 cobra venom gave 100 percent prolongation of survival period and the degree of protection decreases when the time lag for the administration of this drug. Neostigmine bromide was found to be of not much value to counteract the neurotoxicity produced by cobra venom. Results of calcium administration were of a varying nature and require further investigation.

    Studies on the influence of chloramphenicol on thiopentone sodium anaesthesia in dogs
    (Department of Pharmacology and Toxicology, College of Veterinary and Animal Sciences, Mannuthy, 1978) Aravindakshan, C M; KAU; Zacharias, Cherian
    A study was undertaken to find out the influence of chloramphenicol, streptomycin and kanamycin on thiopentone sodium anaesthesia in dogs. Chloramphenicaol 50 mg/kg body weight, streptomycin 10 mg/kg body weight and kanamycin 10 mg/kg body weight were administered intramuscularly at 30, 60 and 120 minutes prior to the administration of thiopentone sodium, which was given at the rate of 30 mg/kg body weight intravenously. These antibiotics (chloramphenicol, streptomycin and kanamycin) produced a slight prolongation in the surgical anaesthesia and sleeping time, induced by thiopentone sodium. Chloramphenicol showed a significant effect over the other two drugs in these respects. It was also noticed that neither thiopentone sodium nor its administration along with chloramphenicol, streptomycin and kanamycin does possess any influence on the PCV and ESR values.

    Studies on the rate of disappearance of chloramphenicol from the blood of goats and calves
    (Department of Toxicology and Pharmacology, College of Veterinary and Animal Sciences, Mannuthy, 1975) Joy, A D; KAU; Rajagopalan, M K
    Studies were conducted in goats and calves on the blood level of chloramphenicol at three dose levels of 10 mg, 20 mg and 30 mg per kg body weight intramuscularly. The data obtained revealed that: Single dose of 10 mg per kg body weight, failed to produce minimum therapeutic concentration (5 mcg/ml) of the drug in blood of both goats and calves. At 20 mg per kg body weight, the minimum therapeutic concentration persisted between second and seventh hour in goats, and second and seventeenth hour in calves. At 30 mg per kg body, weight, the minimum therapeutic concentration maintained between second and eleventh hour in goats and second and nineteenth hour in calves. Peak concentrations of the drug were obtained both in goats and calves between second and third hour after the administration of chloramphenicol. The drug concentration was higher in urine than in blood and minimum therapeutic concentration was found to persist for 24 hours in all the three doses. In a limited attempt made to study the toxicity of chloramphenicol in calves, 100 mg per kg body weight, administered daily, intravenously for 30 days, did not produce acute toxicity. Transient “shock like” symptoms were noticed soon after injection and persisted for 10 to 15 minutes. No alternations in blood constituents could be detected for the 30 days duration.
