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.

    Incidence and treatment of cestodes of dogs in Kerala with special reference to the taenid species
    (Department of parasitology, College of Veterinary and Animal Sciences, Mannuthy, 1982) Narendran Nair, P; KAU; Pythal, C
    Five species of cestodes, viz., dipylidium cenium, Taenia hydatigens, Echinococcus granulosus, Joyeuxiella pasqualei and Diphyllobothrium latum were encountered in dogs in Kerala, of which diphylidium ceninum was the commonest. The incidence of Dipylidium caninum was the highest in animals of the age group of above 5 years, while that of joyeuxiella pasqualei was highest in animals of the age group of above 6 months and upto one year. Echinococcus granuloscus and Taenia hydatigens were most prevalent in the age group of above 5 years. Examination of faecal samples of dogs also revealed that Dipylidium caninum was the most prevalent cestode of dogs. Albendazole at 25 mg/kg body weight. Fenbendazole at 10mg/kg body weight. Hexachlorphene at 15mg/kg body weight, mebendazole at 15 mg/kg body weight repeated for 3 days , niclosamide at 62.5 per Kg body weight and praziquantel at 2.5 mg/kg body weight could remove taenia hydatigena completely. Fenbendazole at 20 mg/kg body weight had an efficacy of only 40% against Ecinococcus granulosus. Fenbendazole at 10mg/kg bodyweight, Mebendazole at 15 mg/kg body weight repeated for 3 days. Niclosamide at125 mg/kg body weight and praziquantel at 5 mg/kg body weight had also 100% efficacy against Dipylidium caninum.

    Pathology of the eye in cattle bearing carcinoma of the mucosa of the ethmoid
    (Department of Pathology, College of Veterinary and Animal Sciences, Mannuthy, 1982) Jose, C J; KAU; Ramachandran, K M
    Eighteen cattle from different parts of Kerala, affected with ethmoid carcinoma were subjected to detailed investigations of the ocular changes. The incidence of eye involvement in cases of ethmoid tumour in cattle was assessed on the basis of reports or informations received from field veterinarians and cattle owners from different dietricts of Kerala. Incidence, clinical manifestations, intraocular pressure, gross pathological cbanges and biometry of the eye were studied. The effect of the tumour mass on the eye and the possible causes for the different ocular changes has been discussed. The highest incidence was found in the age group of six to ten years. The earliest case was recorded in a heifer aged four years. The frequency of the incidence was high in females (88%). Crossbred animals were found to be more affected (83%). The tumour was also encounter~d in three purebred cattle. Ninetyfour percent of the tumour affected animals showed exophthalmos either unilateral (82%) or bilateral (18%). Tbe left eye was affected in 14 percent and the right eye in 86 percent cases. It is suggested that 37 exophthalmos can be considered as a pathognomonic clinical manifestation for ethmoid tumour affected cattle. Blindness was observed in 90 percent of the affected eyes, ectropion in 85 percent cases and corneal cbanges in the form of keratitis or opaCities in 90 percent cases. Episcleritis, anterior uveitis, euphora, purulent discharges were the other clinical manifestations. Glauc~a, was found to be a characteristic feature in ethmoid caroinoma. Involvement of the optic nerve, optic diso, retina, vitreous and other deep structures of the eyes were also notioed by gross examination of the whole eye at autopsy. The lens showed varying degrees of displacement or luxation.

    Fresh water cercarial fauna of Trichur
    (Department of Parasitology, College of Veterinary and Animal Sciences, Mannuthy, 1982) Ambika Prasad, Sarmah; KAU; Raja Mohan, K
    An investigation on the cercarial fauna of fresh water snails in Trichur was conducted for a period of one year (1981 – 1982). Three species of snails viz. Indoplanorbis exustus (Deshayes), Lymnaea luteola f. australis and Thiara (Melanoides) tuberculata were collected from different areas in Trichur. Snails were found to thrive throughout the year if water is available. Seven different types of cercariae could be identified in the present study. They were – 1. An amphistome cercaria of the pigmentata group referable to Cercaria indica XXVI Sewell, 1922 2. An echinostomatid cercaria, further confirmed as cercaria of Hypoderaeum conoideum 3. A xiphidiocercaria resembling Cercaria indica X Sewell, 1922 4. A brevifurcate, non – ocellate, apharyngeal cercaria referable to cercaria of Schistosoma spindale 5. A longifercate cercaria referable to Cercaria hardayali Dutt, 1970 6. A gymnocephalous cercaria resembling Cercaria indica XIV Sewell, 1922 7. Amonostome cercaria comparable to Cercaria indica VII Sewell, 1922 The maximum incidence of cercarial infection in snails was found in the month of August, Mixed infection of cercariae was observed in one Indo plannorbis exustus (Deshayes) and one Lymnaea luteola f. australis snails. The emergence character and detailed morphology of all these cercariae were studied and compared with the available literature. Experimental infection to raise the adults from the larval stage of a trematode was successfully carried out using cercaria of Hypoderaeum conoideum.

    Inheritance of body weight,egg weight and age at first egg in white leghorn birds
    (Department of Animal Breeding and Genetics, College of Veterinary and Animal Sciences, Mannuthy, 1982) Valsala C, Joseph; KAU; Mukundan, G
    An investigation was carried out to study the inheritance of body weights, age at first egg and egg weight in White Leghorn birds. The data required for the study were collected from two strains of White Leghorns maintained in the Farm under All India Co – ordinated Research Project for Eggs, Mannuthy. The Least squares analysis of variance was carried out to find out the effect of hatches on the traits under study. Since the effect of hatch was significant, the data were adjusted for this effect and utilized to estimate heritability, genetic, phenotypic and environmental correlations among body weights and age at first egg. Hatch effect was not significant for egg weight. The averages for body weights (g) at 20 weeks and 40 weeks, age at first egg (days) and egg weight (g) were 1181.5 + 2.8, 1457.0 + 4.0, 166.0 + 0.30 and 51.7 + 0.10 for N strain and 1245.9 + 5.4, 1518.6 + 5.7, 162.1 + 1.1 and 51.7 + 0.10 for P strain respectively. The heritabilities based on sire, dam and sire + dam components of variance were 0.25 + 0.00, 0.36 + 0.01, 0.31 + 0.01, for body weight at 20 weeks; 0.22 + 0.00, 0.50 + 0.03, 0.36 + 0.00 for body weight at 40 weeks; 0.20 + 0.00, 0.22 + 0.03, 0.21 + 0.00 for age at first egg and 0.43 + 0.00, 0.62 + 0.03 and 0.52 + 0.01 for egg weight respectively. In P strain the respective estimates were 0.25 + 0.02, - 0.19 + 0.12 and 0.03 + 0.04 for body weight at 20 weeks; 0.44 + 0.00, 0.27 + 0.04 and 0.35 + 0.02 for body weight at 40 weeks; 0.06 + 0.00, - 0.11 + 0.04 and 0.00 + 0.02 for age at first egg and 0.28 + 0.01, 0.95 + 0.04 and 0.61 + 0.02 for egg weight respectively. The genetic correlations between body weights at 20 weeks and 40 weeks and between body weights and egg weight were positive, between body weights and age at first egg negative and between age at first egg and egg weight positive. Environmental and phenotypic correlations between the traits were generally of low magnitude.
