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.

    Fertility management of early post- partum cows with gonadotrophin releasing hormone and prostaglandin F2 alpha
    (Department of Animal Reproduction, College of Veterinary and Animal Sciences, Mannuthy, 1999) Jayakumar, C; KAU; Balakrishnan, P P
    With the object of evaluating the e f f i.ca cy of gonadotrophin releasing hormone (GnRH) and prostaglandin F2 alpha (PGF2 alpha) for induction of early postpartum oestrus and reduction of calving to conception interval, 30 crossbreds cows which had normal parturition, selected from Livestock Research Station, Thiruvazhamkunnu were allotted to three different treatment groups. Ten cows each in gro~p I, II and I I I were administered intramuscularly 5 ml Receptal, 5 ml Dinofertin and 5 ml Saline respectively on 14th day of calving. The time taken for regression of pregnancy corpus luteum averaged 14.5 ± 0.37, 14.9 ± 0.45 and 15.3 ± 0.87 days respectively in the three groups. Uterine involution was complete in 25.3 ± 0.47, 25.0 ± 0.77 and 34.6 ± 1.79 days respectively. Analysis of data revealed significant variation in the uterine involution between experimental and control groups. The interval from treatment to onset of oestrus was 18.1 ± 1.69, 19.5 ± 1.93 and ~0.7 ± 3.37 days respectively for the three groups and the interval from calving to first exhibited oestrus was 32.1 ± 1.69, 33.5 ± 1.93 and 46.11 ± 3.19 days respectively. Statistical analysis revealed significant variation in the interval from calving to first oestrus and treatment to onset of oestrus between treatment and control groups. Percentage of cows that evinced oestrus within 45 d of calving were lOO, 90 and 50 respectively in the three groups. This variation between treatment and control groups was statistically significant. A higher proportion of cows from group I and 11 showed medium to high intensity of oestrum when compared to control. The ovulation rate in cows that exhibited oestrus upto 45 d of calving wa$ 90, 77.77 and 60 per cent respectively in group I, 11 and Ill. There was significantly higher progesterone level in the ovulated cows of the treatment groups than that of control. The interval from calving to first insemination in group I, 11 and III were 56 ± 1.99, 52 ± 1.24 and 65.77 ± 2.90 days respectively and the interval from calving to coneption were 69.77 ± 3.70, 75.87 ± 5.62 and 95.0 ± 6.04 days respectiyely. The variations in service period and calving to conception interval between treatment and control .groups was statistically significant. The first insemination conception and overall conception rate with three or more A.I. were 30 and 90 per cent for group I, 20 and 70 per cent for group 11 and 11.1 and 55.5 per cent for group Ill. The A.I. index was 1.7, 2.25 and 2.8 for the three groups respectively. Eventhough, there was no significant difference in the first insemination conception and A. I. index between the three groups, there was apparently better conception rate in the treatment groups with reduction in A.I. index. However, no '. significant variation in any of the reproductive parameters between the two treatment groups was noticed. The accuracy of prediction of pregnancy by progesterone assay on day 20 was only 70 per cent as against 100 per cent for non-pregnant animals. The accuracy of pregnancy diagnosis by this method can be improved by a second assay on day 30, which will cover loss of pregnancy due to early embryonic death. It is concluded that GnRH er PGF2 alpha administered on the fourteenth day of calving will help early induction of oestrum and conception and is therefore cost-effective.
