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.

    Utero-tubal insufflation technique for diagnosis of tubal impatency in cows
    (Department of Animal Reproduction, College of Veterinary and Animal Sciences, Mannuthy, 1981) Athman, K V; KAU; Neelakanta Iyer, C P
    The objective of the present study was to design an apparatus for utero-tubal insufflation test and to standardize its use in both excised genitalia and in live animals for the diagnosis and treatment of tubal impotency. Perfect obturation of the cervix was obstained using a stainless steel catheter with 22 FR. Neo Foley’s latex catheter sleeved over. Unilateral and bilateral impotency were recorded in 8.70 and 19.25 per cent of the excised genitalia. The incidence of unilateral and bilateral impotency in 37 infertile animals were found to be 2.70 and 13.52 per cent respectively. The mean pressure at which air escaped from both the tubes in excised genitalia was 128.12 mm. Hg. In cows and 148.93 mm. Hg. In heifers. On the contrary in experimental animals the corresponding pressure in cows and heifers were 116.38 mm. Hg. And 127.50 mm. Hg. Respectively. It was observed that a higher pressure was required to open both the tubes in heifers than in cows. Blown up condition of the uterus took place in excised genitalia of cows and heifers between 100-280 mm. Hg. And 100-260 mm. Hg. Respectively. The pressure range for producing “blown up” condition in experimental animal was found to be 120-220 mm. Hg. In cows and 195-200 mm. Hg. In heifers. Since the safety margin was estimated to be 60.00 mm. Hg. In experimental cows, the test is considered to be a safe diagnostic test for tubal impotency. Although uterus might be “blown up” in a very few cases at a pressure lower than the higher pressure for escape of air from normally patent tubes, the test will not endanger the life of the animal. Since 69.56 percentage of cows with bilateral patency of salpinx on testing conceived after insemination, utero-tubal insufflation test could also be exploited for the treatment of temporary tubal blockage.

    Reproductive performance of cows under homoeothermal disturbances
    (Department of Animal Reproduction, College of Veterinary and animal Sciences, Mannuthy, 1995) Athman, K V; Sudarsanan, V
    Based on the data on the maximum minimum temperature and humidity for a period of two years a year of study was divided into four seasons of JJA SON DJF and MAM The mean maximum environmental temperature of the seasons were 29 56 31 52 32 73 and 34 88°C respectively Two thousand two hundred and ninety eight cows brought to the AI centre from the homesteads of Mannuthy were grouped into 11 treatments of pre and post insemination rests and no rests They were bred by artificial insemination and results of insemination were assessed on the basis of non return Mean conception rate of the seasons were statistically analysed to know the effect of environmental temperature and the effect of pre and post insemination rests to the animals There was no significant difference m conceptions between seasons between the post insemination rests and no rests and between pre insemination rests of 30 and 60 minutes and no rest Conception per cent was significantly higher in the animals those were given pre insemination rest for 90 and 120 minutes Animals with light coat colour had a significantly higher conception rate than those with dark colour irrespective of the seasons Animals inseminated m the afternoon were generally found to have a better conception rate than those inseminated m the forenoon There was no significant difference in the conception rate of heifers and cows both between seasons and between themselves So also there was no significant difference in conception rate of parity groups both between seasons and between themselves Statistical analysis of seasonal mean weight of foetal membranes mean number of cotyledons and mean area of cotyledons and mean birth weight of calves did not show any correlation to suggest influence of seasonal environmental temperature on placental development and birth weight of calves
