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.

    Non-antibiotic therapy for sub clinical endometritis in repeat breeding cattle
    (Department of Animal Reproduction, Gynaecology and Obstetrics, College of Veterinary and Animal Sciences, Mannuthy, 2007) Safna Isaac, M; KAU; Joseph Mathew
    The present investigation “Non-antibiotic therapy for sub clinical endometritis in repeat breeding cattle” was conducted during the period from July 2006 to February 2007 in cross bred animals brought for artificial insemination. The material for the study consisted of repeat breeder cows and heifers maintained at University Livestock Farm, Mannuthy and those presented at Artificial insemination centre and Bull station attached to the Department of Animal Reproduction, Gynaecology and Obstetrics, College of Veterinary and Animal Sciences, Mannuthy. The incidence of repeat breeding, the occurrence of sub clinical endometritis and various aspects of oestrous cycle were studied. Repeat breeding animals with sub clinical endometritis were randomly selected and allotted to groups I to V comprising of 10, 12, 12, 10 and 10 animals respectively and following treatment regimes were undertaken. Group I animals were given 50 ml of one per cent lugol’s iodine intrauterine 24 h prior to insemination. Group II animals were given 50 ml of one per cent lugol’s iodine intrauterine 24 h after insemination. In group III, a synthetic PGF2 alpha analogue (CLOSTENOL) was given intramuscularly on eleventh day of oestrous cycle followed by timed inseminations at 72 and 96 h of injection. Group IV animals were subjected to prostaglandin injections at 11 days interval on the luteal phase of oestrous cycle followed by timed inseminations at 72 and 96 h of injection. Group V animals were artificially inseminated without any treatment, which formed the control group. The over all incidence of repeat breeding was found to be 19.01 per cent, out of which 46.36 per cent showed sub clinical endometritis. The characteristics of oestrual cervical mucus and physical changes in the genital tract were examined in detail and found that almost all treatment groups followed similar pattern irrespective of induced and natural oestrum. The intensity of oestrum after induction using prostaglandin analogue was found to be high in most of the repeat breeders with sub clinical endometritis. Time taken for induction of oestrus in animals belonging to group III and IV were 59.38 +2.81 h and 58.88 + 2.75 h respectively. The mean duration of oestrum after induction using PGF2 alpha analogue in group III and IV were 37.5 + 3.70 h and 38.63 + 3.65 h respectively. The conception rates of animals in different experimental groups were 40, 50, 50, 40 and 20 per cent in groups I, II, III, IV and V respectively. The conception rate was highest, 50 per cent in groups II and III, in which animals were subjected to post AI lugol’s iodine and single regime prostaglandin therapy respectively. However, better conception rates could be obtained in all treatment groups when compared to control group in which the success rate was only 20 per cent. Hence it could be inferred that both lugol’s iodine and prostaglandin can be used effectively in the treatment of sub clinical endometritis in repeat breeders. However, treatment with lugol’s iodine is comparatively less expensive and it is easily available also, so can be recommended as the drug of choice for tackling cases of repeat breeding with sub clinical endometritis.
