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.

    Management of Oestrous Cycle in Crossbred Cattle Using Prostaglandin
    (Department of Animal Reproduction, College of Veterinary and Animal Sciences,Mannuthy, 1994) Ajit Kumar, G; KAU; Madhavan, E
    With the object of studying the efficacy of administration of prostaglandin F2 alpha in the management of oestrous cycle and fertility of fixed time insemination in induced oestrus, 96 heifers and cows which were cycling, selected from Kerala Agricultural University Livestock Farms, were allotted to three different groups. Sixteen heifers and 16 cows in group I were given 25 mg PGF2 alpha (Lutalyse) intramuscularly when they had functional corpora lutea, while in group II, 16 heifers and 16 cows were administered two injections of PGF2 alpha 25 mg each 13 days apart. Sixteen heifers and 16 cows were treated as control (Group III). Twelve heifers (75%) and 16 cows (100%) in group I and all animals in group II responded to treatment. Mean time taken for induction of oestrus was 56.64 and 65.44 h respectively in heifers and cows. This difference was statistically significant. Parity of cows significantly influenced the time taken for induction of oestrus. Duration of oestrus was significantly different between heifers (21.86 h) and cows (31.13h) of the experimental group. Significant difference in the duration of oestrus was observed among cows between experimental and control groups. All experimental animals which responded to PGF2 alpha showed marginal increase in physical characters of the reproductive tract like vulval oedema, hyperaemia of vaginal mucosa, vulval discharge and tonicity of uterine horns. Majority of the experimental animals showed medium to high intensity of oestrus compared to natural oestrus. The first insemination and overall conception rates of heifers in group I, inseminated 72 h post-treatment, were 33.33 and 66.67 per cent respectively as against 33.33 and 50 per cent when inseminated 96 h post-treatment. Cows in groupI recorded 25 and 62.50 per cent and 37.50 and 62. 50per cent first insemination and overall conception rates respectively when inseminated 72 h and 96 h post-treatment. When heifers and cows in group II were inseminated 72h after the administration of the second dose of PGF2 alpha, 12.50 and 25 per cent conceived at first insemination with overall conception rate of 62.50 and 37.50 per cent respectively. The corresponding values in group II, when inseminated 96 h, were 25 and 12.5 per cent and 50 and 12.5 per cent respectively. Among control 6.25 per cent of heifers and 18.75 per cent of cows conceived at first insemination. The first insemination conception rate of heifers of experimental (25%) and control groups (6.25%) were significantly different. However, overall conception rate did not differ between the three groups. There was no influence of parity or season on the conception rate. Similarly the time taken for induction of oestrus, duratioh of oestrus, physical changes of the reproductive tract during oestrus and intensity of oestrus did not affect the conception rate. Heifers and cows required 1.88 and 1.93 inseminations respectively per conception when treated with PGF2 alpha as against 3.14 and 3.33 in the control group. Though, the present investigation revealed that PGF2 alpha can be used in the management of oestrous cycle in crossbred heifers and cows with fixed time insemination, the high cost of the drug and the conception rate obtained warrant further studies on fertility in relation to detected oestrus and fixed time insemination after the administration of PGF2 alpha.

    Food consumption pattern of rural house-holds below poverty line as influenced by food subsidies distributed through fair price shops
    (Department of Home Science, College of Agriculture,Vellayani, 1994) Priya Gopinath R; KAU; Prema L
    A Study on the food consumption pattern of rural household below poverty line as influenced by the food subsides distributed through fair prices shops was taken up to evaluate the socio – economic and personal characteristic of the beneficiaries, daily food consumption pattern and contribution of food subsidies available through fair price shops on their daily diet. On the basis of their participation in public distribution system 120 households of 4 groups with 76 to 100 percent participation , 51 to 75 percent participation , 26 to 50 percent participation and less than 25 percent participation were selected for the study. All the house holds surveyed were more or less in similar socio economic back ground. Present of the monthly income in all the four groups was incurred for food especially for cereals. It was also found that percentage cereal expenditure was increasing from group 1 to group4. Among the house holds in the four groups more percentage of house holds were spending less than ten percent of their total food expenditure for purchasing food ration. A comparison among four groups revealed that percentage of ration expenditure against total food expenditure was low in group 1 and this was gradually increasing from 1 to group 4. All households in the four groups were found to include rice, sugar, coconut, milk, spices and condiments and oil every day. Rice , wheat, sugar and oil were purchased from fair price shops. Rice and oil distributed through this shops were not adequate for the households and hence open marker services were utilized. House holds under groups 1 were found using the ration cards regularly in every week and households in group 4 were not in the habit of purchasing ration regularly. The beneficiaries had favourable views about the quantity and quality of food subsidies supplied through this system. Food consumption pattern of all households in 4 groups in revealed that the food consumption of households were better in group 1 than the house holds in other 3 groups. But the diets of all the four groups were below the recommended daily allowances. Nutritional status of different age groups was ascertained in the 20households selected (10 each from group 1 and group 4). It was found that clinical scores based on various deficiency diseases was higher for family members belonging to group 2. Teethcarries and spongy bleeding of gums were common among the children of the two groups of the house holds. Haemoglobin level was below average in adult females and adolescent females in both the groups. The present study gives an indication that public distribution system has positively influenced the regular beneficiaries and prolonged implementation of the programme is one of the methods to achieve sufficient health profile for the population in below poverty line of the country.

    Consumer packaging of selected vegetables
    (Department of Processing Technology, College of Horticulture,Vellanikkara, 1994) Sunil Kumar, G; KAU; Raju, V K
    The present study on “Consumer packaging of selected vegetables” was conducted in the Department of Processing Technology, Kerala Agricultural University, Vellanikkara during June 1992 to October 1993. The study on standardization of precooling treatments to improve the postharvest life of the vegetables viz., amaranth, brinjal, chilli, cowpea, okra and tomato revealed that precooling the vegetables immediately after harvest reduced the physiological loss in weight (PLW) and enhanced the marketability both under ambient and refrigerated storage environments. The effect of precooling treatments was more pronounced when precooling was immediately followed by refrigerated storage. Among precooling treatments, contact icing and cold water treatments were found superior to tap water treatment in most of the cases. The study on precooling and packaging treatments on amaranth, brinjal, chilli, cowpea, okra and tomato revealed that precooling followed by immediate packaging of the vegetables in 100 or 200 gauge polyethylene or polypropylene bags reduced the PLW considerably. Moreover, packaged vegetables had better consumer acceptability and has remained marketable for longer periods both under ambient and refrigerated storage conditions. In most of the cases, contact icing and cold water treatments gave better results among precooling treatments. With respect to packaging, under ambient temperature storage, 100 or 200 gauge polyethylene or polypropylene bags with 0.5 per cent ventilation was found to be ideal except in okra where unventilated polybags was the best. In refrigerated storage for brinjal, chilli and tomato, polybags with 0.5 per cent ventilation was found to be ideal. For amaranth, cowpea and okra polybags without ventilation was found to be more efficient. Refrigerated storage enhanced the shelf life of packaged vegetables 3-4 times as compared to packaged vegetables kept under ambient temperature storage. The storage study on precooled portioned vegetables viz., ashgourd, elephant foot yam, oriental pickling melon, pumpkin and snakegourd packaged in polymeric films revealed that portion packaged vegetables had lower PLW and remained marketable for longer periods both under ambient and refrigerated storage environments. Wilting, shrinkage, shriveling, discolouration and microbial rotting were the common types of spoilage in packaged vegetables. Cost- wise, among precooling treatments, tap water treatment was the cheapest followed by cold water and contact icing. Among polybags polypropylene was cheaper compared to polyethylene.

    Preparation of mozzarella cheese using skim milk filled with coconut milk
    (Department of Dairy Science, College of Veterinary and Animal Sciences, Mannuthy, 1994) Gnana Selva, Johnson; KAU; Mukundan, M
    A detailed study was carried out to determine the quality of coconut fat filled milk for the preparation of Mozzarella cheese and why drinks. Literatures based on filled milk products has been reviewed, apart from the preparation of cheese and why drinks. The control samples of Mozzarella cheese and whey drinks were prepared using cow’s milk. Experiment I products were prepared from milk in which 50 per cent of milk fat was replaced with coconut fat. Experiment II products were prepared from cheese milk in which 100 per cent of milk fat was replaced with coconut fat. All the samples of milk were standardized to 4 per cent fat. A total of 6 trials were carried out to obtain reliable data for statistical analysis. The acidity, pH, stretchbility and FDM content were found to be similar in control, experiment I and II Mozzarella cheese. Eventhough, the control Mozzarella cheese were found to have slightly higher yield protein, fat and lower moisture content, the experimental I and II. Mozzarella cheese also satisfied the requirements for good quality Mozzarella cheese. The control Mozzarella cheese got maximum score on sensory evaluation than the experiment I and II Mozzarella cheese. Pineapple and Lemon falvoured control, experiment I and II whey drinks were found to be equally acceptable with nodifference on storage studies ar 5 + loC. Total bacterial count on whey drinks were also made. The studies revealed that the cow milk in which the milk fat replaced to the extend of 50 per cent and 100 per cent with coconut fat can be effectively utilised for preparation of Mozzarella cheese. The quality of such cheese is comparable with that made from cow milk.

    Metabolic profile of downer cow syndrome
    (Department of Clinical Medicine, College of Veterinary and Animal Sciences,Mannuthy, 1994) Mhachuvino Catherine, Khatsu; KAU; Alikutty, K M
    The metabolic profile of ‘Downer Cow’ syndrome in field conditions was studied. Fourteen field cases of ‘Downers’ in crossbred dairy cows aged three to thirteen years, ranging from 250 to 300 kg body weight from Trichur district were selected at random and utilized for the study. Fourteen apparently healthy crossbred dairy cows of similar age group and body weight, maintained under similar conditions of feeding and management from the area from which the clinical cases studied were also selected at random and utilized as the healthy controls. Samples of blood for haematological and biochemical parameters, urine and dung from both healthy and diseased animals were collected and analysed using standard methods. Analyses of the data from fourteen diseased animals indicated a higher incidence in Jersey crossbred cows during summer season. Prominent clinical signs were sternal recumbency exhibiting hindquarter weakness and reduced feed and water intake. However, the affected animals remained bright and alert with no evidence of any systemic disturbances. The clinical data were within physiological limit. Highly significant increase in PCV and significant increase in Hb but no significant difference in ESR, RBC and WBC were observed. Lymphopenia, neutrophilia and eosinopenia were observed with no variation in basophils and monocytes counts. Biochemically, hypocalcaemia,hypophosphataemia, hypoproteinaemia and hypoalbuminaemia were obtained from ‘Downers’ with no significant variation in blood glucose, urea nitrogen, sodium, potassium, magnesium and albumin/globulin ratio. Urinalysis revealed no consistent result indicative of any systemic involvement and no parasitism on dung examination microscopically.
