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.

    Prostaglandin therapy for post-partum clinical endometritis
    (Department of Animal Reproduction, College of Veterinary and animal Sciences, Mannuthy, 1993) Jacob, T C; KAU; Madhavan, E
    The object of the investigation was to evaluate the therapeutic values of alpha# for evolving a non antibiotic alternative for the treatment of post partum clinical endometritis. For this, 42 cross-bred cows, belonging to University Livestock Farm, Mannuthy, having post partum clinical endometritis were divided into four groups. Group I consisted of 10 animals which were watched for their natural oestrus and inseminated twice at 24 hours interval. In group II, 11 animals were observed for their natural oestrus and inseminated twice at 24 hours interval and were given post insemination intrauterine antibiotic treatment 24 hours later based on antibiotic sensitivity test. Eleven animals in group III were subjected to induction of oestrus by administration of PGF2 alpha (Lutalyse) 25 mg intramuscular 8-12 days of their cycle and inseminated twice at 24 hours, at the induced oestrus. Group IV consisted of 10 animals subjected to induction of oestrus as in group III and inseminated twice at 24 hours interval and were given post insemination intrauterine antibiotic therapy based on sensitivity tests, 24 hours later. The observations made and inferences drawn are given below. The interval from the administration of PGF2 alpha to the onset of oestrus ranged from 4.8-120 hours (mean 61.81 hours) and 36 to 72 hours (mean 54.0 hours) in group III and IV, respectively. The mean duration of oestrus was 21.6 hours, 23.36 hours, 28.36 hours and 31.60 hours in the four groups respectively. The duration of oestrus showed significant variation between groups I and IV (f = 2-8910) and between groups II and IV (t* = 2.6445). The percentage of intense, medium and weak oestrus was 66.66, 23.80 and 9.52 per cent respectively in natural oestrus and 66.66, 19.04 and 14.28 in induced oestrus respectively. The difference in the intensity of oestrus between natural and induced oestrus was not significantly different, although, a slightly high incidence of weak oestrus was observed, when oestrus was induced with Lutalyse. Physical changes of the reproductive tract' like oedema of the vulva, congestion of vulval mucosa and sliminess did not show any variation between the natural oestrus and induced oestrus. The percentage of animals showing purulent discharge, discharge with flakes and cloudy discharge showed a marked reduction when treated with PGF2 alpha alone and a combination of PGF2 alpha and antibiotics. Similarly the percentage of animals showing clear discharge increased enormously by above treatments. The bacterial organisms isolated from the uterine discharges were citrobacter spp. 23.84 per cent, Bacillus spp.. 23.80 per cent, S. aureus .14.28 per cent, Pseudomonas 14.28 per cent, Corynebacterium spp. 9.52 per cent, Coagulase negative staphylococci, 9.52 per cent and the yeast Candida guilliermondii 4.76 per cent. Gentamicin was the most sensitive antibiotic for most of the organisms isolated, followed by chloramphenicol, oxytetracycline and sulphadiazine. Penicillin was the most resistant followed by streptomycin and nitrofurantoin. Significant difference in the overall conception rate was observed between different groups; the overall conception rate was significantly higher in group IV than in group I and II (t1 = 4.8341 between groups I & IV and t' = 2.9186 betweengroups II & IV). Significantly higher conception rate was observed in group III than group I also (t ' = 5.5886). The number of inseminations required per conception was lowest in group III and highest in group I. Thus, it appeared that PGF2 alpha in combination with antibiotic was beneficial in the treatment of clinical endometritis. But since the number of inseminations required for conception was lower in group III than group IV and because, there is no significant difference in the overall conception rate, between these two groups, it could be inferred that administration of antibiotics along with P G F 2 alpha did not have any added advantage. Furthermore, considering the harmful effects of administration of antibiotics, it may be stated that PGF2 alpha alone would be beneficial in the treatment of post partum clinical endometritis and can be recommended as the drug of choice
