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.

    Managemental effects of synchronization of oestrus in goats
    (Department of Livestock Production Management, College of Veterinary and Animal Sciences, Mannuthy, 1993) Shivkumar, S; KAU; Thomas, C K
    An experiment was conducted to study the managemental effects of synchronization of oestrus in goats using parentral administration of PGF2 alpha, on a flock of Malabari, Malabari x Saanen and Malabari x Alpine goats maintained at the Agricultural University Goat Farm, Mannuthy. Forty cyclic goats were selected in pairs on the basis of similarity in genetic group, body weight and age. The does from each pair were allotted to two groups at random. Out of these one group at random formed the treatment group and the other control. The goats in the treatment group were given two injections of 10 mg (I/M) each of PGF2 alpha separated by 11 days, in two batches of 10 goats each. The animals were mated at the synchronized oestrus following the second PG injection. The does in the control group were mated as and when they came to oestrus. Heat detection in the does was carried out by parading the vasectomised bucks twice daily and by observing the behavioural manifestations of oestrus. The results and conclusions of the study are given below. The PGF2 alpha treated goats showed 75 and 100 per cent oestrus synchrony after a mean interval of 45.93+2.19h and 48.38+2.06 h following the. first and second injection of PGF2 alpha respectively. Of the various signs of oestrus only rapid waving of tail in the presence of male and vaginal mucous discharge were observed in all the does in oestrus. Various signs of oestrus behaviour including receptivity was found to be more pronounced in oestrus synchronized does using PGF2 alpha than in the controls. Mated does showed pricking of ear and arching of back as post coital reactions. Conception rate following mating at the first oestrus was better in the treatment group (85%) than the controls (75%). Body weight changes during pregnancy was not found to be affected by synchronization of oestrus with prostaglandin F2alpha. Mean gestation period in the treatment group was ,148.14+0.80 days compared to 143.88+0.78 days in the controls, the difference being significant (P < 0.05). Overall 61.3 per cent of the parturitions were observed to occur between 0600 to 1800 hours. Maternal behaviour studies showed no significant difference between the does in the control (av. score 3) and treatment group (av. Score 2.8). Multiparas were observed to possess better maternal Instinct than the primipara does. The new born kids attempted to stand up within 8 to 15 minutes and 68 per cent of them suckled from the dam's teat within one hour of birth. In the control group 88 per cent of the kiddings were singles and 11.77 per cent twins compared to 85.71 per cent singles and 14.29 per cent twins in the treatment group. Comparing the growth of kids with respect to body weights and body measurements at fortnightly intervals from birth to 90 days of age, showed that the growth rate of kids born from synchronized oestrus was similar to that of control kids. Suckling behaviour in the kids revealed that the overall mean duration of suckling was 2.61 minutes and mean rate of suckling was 49.65 g per minute. It was observed that the rate of butting and intensity of tail wagging increased as the flow of milk from the teats got reduced. The mean daily milk yield from first to thirteenth week of lactation in the control and treatment g roups were found to be 0.509+0.015 kg and 0.493+0.014 kg respectively. Man nours requirements to look after the does and raising the kids born to tham to 90 days of age in both the control and treatment group, revealed that there was a man hour saving of 12.3 per cent in the oestrus synchronized group (treatment) than the untreated controls.
