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.

    Effect of replacing dried fish with lysine and methionine in the calf starter on the growth performance of crossbred calves
    (Department of Animal Nutrition, College of Veterinary and Animal Sciences, Mannuthy, 2004) Jith John, Mathew; Ally, K
    A growth trial was conducted with fourteen crossbred calves below one month of age for 145 days to study the effect of replacement of unsalted dried fish in the calf starter with a total vegetable protein source supplemented with lysine and methionine. Calves were divided into two groups as uniformly as possible and allotted randomly to two dietary treatments. The control group was fed with a calf starter containing unsalted dried fish. The treatment group was fed a calf starter with only vegetable protein sources formulated to be isonitrogenous and isocaloric with control calf starter and equated by supplementation, with the same as regard to amino acids lysine and methionine plus cystine. Statistical analysis of the data showed that there was no significant difference in any of the parameters recorded during the study. An average daily gain of 325 grams and 348 grams were obtained in calves fed with the control and treatment diets respectively. Feed to gain ratio for the control and treatment groups were 3.85 and 3.81 respectively. Dry matter intake and haematological parameters such as haemoglobin, serum phosphorus, serum calcium, plasma glucose, serum total protein and blood urea nitrogen were similar in calves receiving the two dietary treatments. The digestibility coefficients of nutrients observed were 66.37 and 65.84 for dry matter, 72.21 and 72.36 for crude protein, 64.28 and 61.85 for ether extract, 62.34 and 60.71 for neutral detergent fibre and 51.95 and 52.25 for acid detergent fibre for the control and treatment diets respectively. Identical performance was obtained in all the parameters recorded. Cost per kilogram body weight gain was Rs 71.40 for the control group and Rs 69.63 in the treatment group. It could be inferred from the study that unsalted fish in a calf starter can be fully replaced by plant protein sources supplemented for existing deficiencies in lysine and methionine plus cystine to obtain similar growth performance of cross bred pre-ruminant calves.

    Effect of urea as source of rumen degradable preotein on milk production of crossbred cows in early lactation
    (Department of Animal Nutrition, College of Veterinary and Animal Sciences,Mannuthy, 2005) Sheena Joseph, KAU; Ally, K
    A study was conducted with crossbred cows to assess the effect of urea as a source of rumen degradable protein on the milk production in early lactation. Eight crossbred cows within 20 days of lactation were selected as uniformly as possible with regard to their age, parity, weight and milk yield. They were allotted to the four dietary treatments in a switch over design. The four concentrate mixtures contained 16.93, 17.37, 19.92 and 19.92 per cent crude protein (CP) and 70.60, 69.24, 70.26 and 68.98 per cent TDN, respectively. The levels of rumen undegradable protein (UDP) and rumen degradable protein (RDP) in the four concentrate mixtures were 28, 39.15, 26.46 and 40 per cent of CP as UDP and 72, 61.85, 73.54 and 60 per cent of CP as RDP, respectively, on DM basis. There was no significant effect (P>0.05) of dietary CP or UDP levels on the body weight, dry matter intake and milk production of animals. The inclusion of urea at different CP or UDP levels did not show any marked influence on the production performance of the animals. There was no significant difference in any of milk composition parameters except MUN which was significantly higher (P<0.05) with 20 per cent concentrate mixtures compared to17 per cent concentrate mixtures at both levels of degradability. The haematological and biochemical parameters such as haemoglobin, plasma glucose, plasma urea nitrogen, plasma creatinine, plasma calcium, plasma phosphorus, plasma total protein and albumin estimated at the end of each feeding period were not significantly affected (P>0.05) by the four dietary treatments. There was no significant effect (P>0.05) of four dietary combinations on rumen fermentation parameters such as rumen pH, total volatile fatty acids and (TVFA) and rumen ammonia nitrogen (NH3–N) concentration. The cost of production per kg milk produced was Rs.7.25, 8.10, 8.05 and 9.09, respectively, for the four dietary treatments. From the overall results obtained in the present study, it could be concluded that a 17 per cent CP concentrate mixture with 28 per cent UDP was sufficient for meeting the protein requirement of early lactating crossbred cows producing about 10 kg milk per day. The study also revealed that one per cent urea can be added in the concentrate mixture of early lactating cows as a source of RDP without any deleterious effect.

    Effect of dietary Cation-Anion balance on growth performance of broiler chicken
    (Department of Animal Nutrition, College of Veterinary and Animal Sciences, Mannuthy, 2005) Mary Juliet Francis; KAU; Viswanathan, T V
    An investigation over a period of six weeks was carried out to study the effect of dietary cation-anion balance on growth performance of broiler chicken. One hundred and sixty commercial day-old broiler chicks were randomly allotted to four dietary treatments viz., Tl, T2, T3 and 14 having four replicates each. The experimental diets were standard broiler ration with varying DCAB of 260 meq/kg (Tl, control), 210 meq/kg (T2), 310 meq/kg (T3) and 360 meq/kg (T4). Cation-anion balance was varied using sodium bicarbonate and ammonium chloride. Results indicated that the dietary treatments did not differ significantly in body weight, weight gain, feed conversion ratio, feed intake, water consumption and processing yields. Body weight at the end of six weeks was 2069, 2031, 2047 and 2020 g and the cumulative mean body weight gain was 2023, 1984, 2000 and 1973 g for Tl, T2, T3 and T4, respectively. Average daily feed intake was 159.39, 164.46, 166.65 atid 169.81 g and mean cumulative PGR were 2.04, 2.02, 2.04 and 2.09, respectively, for Tl, T2, T3 and T4. No significant difference was observed in serum minerals or biochemical parameters such as serum uric acid, cholesterol and glucose. Birds in T3 and T4 showed significantly higher (P<0.05) intake and balance of sodium than Tl and T2. Retention of chloride was significantly higher (P<0.05) for T3 and T4 whereas chloride intake was significantly lower (P<0.05) for T3 and T4. Overall evaluation of the results of the present study reveals that dietary cation-anion balance does not have a significant influence on growth performance of broiler chicken.

    Growth performance of broiler chicken fed on fermented fish waste silage ration
    (Department of Animal Nutrition, College of Veterinary and Animal Sciences, Mannuthy, 2005) Smitha, N F; KAU; Mercy, A D
    An investigation spread over a period of six weeks was carried out to study the effect of replacing unsalted dried fish with fermented fish waste silage on nutrient utilization and growth performance in broiler chicken. One hundred and eighty day-old broiler chicks (Vencob) were divided into three identical groups having five replicates in each group with 12 birds in each replicate and allotted randomly into three dietary treatments viz., T1, T2 and T3. The three groups of birds were maintained on isonitrogenous and isocaloric rations in which protein of unsalted dried fish was replaced by protein from fermented fish waste silage at 0, 50 and 100 per cent levels. Birds were fed broiler starter rations up to four weeks of age and then they were switched to broiler finisher rations till the end of the experiment. The birds maintained on the three dietary treatments T1, T2 and T3 had almost similar growth rate (P>0.05) with a cumulative mean body weight gain of 1401.45, 1434.48 and 1491.31 g, respectively. The cumulative feed intake and cumulative feed conversion efficiency did not differ significantly (P>0.05) between treatments, the cumulative feed conversion efficiency being 2.12, 2.08 and 2.09, respectively for the birds of T1, T2 and T3. Nitrogen retention and balance were similar for the diets T1, T2 and T3. The retention and balance of calcium and phosphorus were also similar. Serum calcium, phosphorus, cholesterol, glucose, creatinine and uric acid contents were not significantly influenced by the inclusion of fermented fish waste silage. Serum triglyceride was significantly reduced (P<0.05) in T2 and T3 when compared to that of T1. Birds maintained on T3 registered significantly lower (P<0.05) ready-to-cook yield when compared to T1 fed on control diet. The cost of feed per kg gain of birds in the three dietary treatments was Rs. 20.15, 19.83 and 19.73, respectively. Overall evaluation of the results of the present study revealed that fermented fish waste silage could be used economically as a substitute for unsalted dried fish in the ration of broilers on protein basis, without any adverse effect on growth rate and feed conversion efficiency, while, the ready-to-cook yield tended to be lower in birds receiving diets with 100 per cent fermented fish silage.

    Utilization of urea at different stages of development of rumen in weaned calves
    (Department of Animal Nutrition, College of Veterinary and Animal Sciences, Mannuthy, 2005) Raja, D; KAU; Viswanathan, T V
    An experiment was conducted with eighteen female cross bred calves below one week of age for 150 days to assess the optimum age for the utilization of urea and also the health status of urea fed calves. Calves were divided into three groups as uniformly as possible and allotted randomly to three treatments T1, T2 and T3. Calf starter as per BIS specification (Diet 1) and calf starter with 2 per cent urea (Diet 2) formed the experimental diet. Both the diets were iso-nitrogenous and iso-caloric. Calves in the T1 were fed with diet 1 from two weeks to five months. Calves in the T2 were fed with diet 1 from two to twelve weeks, later on with diet 2 till five months. Calves in the T3 were fed with diet 1 from two to eight weeks, later on with diet 2 till five months. Milk was fed till three months of age as per the requirement. Green grass and paddy straw were fed ad libitum. Average daily gain and daily dry matter intake, respectively were 305 g and 1.39 kg for the calves in T1, 299 g and 1.43 kg for the calves in T2, and 321 g and 1.53 kg for the calves in T3, and the values were not significantly different (P>0.05). Feed to gain ratio for T1, T2, and T3 were 4.61, 4.85 and 4.83, respectively and were not significantly different among treatments. Blood biochemical parameter such as blood glucose, AST, total bilirubin, blood urea nitrogen, creatinine, total protein, albumin, globulin, A:G ratio did not show any significant difference. Urinary parameters such as urea and creatinine also did not show any significant difference but there was a trend for increased urea excretion in those calves fed urea. Rumen liquor parameter such as pH, MBRT, protozoal activity, TVFA, rumen NH3-N also did not statistically differ (P>0.05). The digestibility coefficient of nutrients observed were 62.26, 59.15, and 60.00 for dry matter, 64.92, 64.89 and 64.91 for crude protein, 70.83, 72.40 and 70.13 for ether extract, 61.39, 58.32 and 62.50 for neutral detergent fibre, 49.81, 47.92 and 51.52 for acid detergent fibre for T1, T2 and T3, respectively. There was no significant difference between the treatments. Cost per kilogram body weight gain was Rs. 73.45, 73.13 and 70.67, respectively for T1, T2, and T3. It could be inferred from the study that urea could be utilized by calves from nine weeks of age without any deleterious effect.

    Effect of dietry iron and supplementation of phytase on growth and mineral availability in broiler chicken
    (Department of Animal Nutrition, College of Veterinary and Animal Sciences, Mannuthy, 2004) Anup Kollanoor, J; KAU; Syam Mohan, K M
    An investigation over a period of eight weeks was carried out to study the effect of dietary iron and supplementation of phytase on growth and mineral availability in broiler chicken. One hundred and ninety two day-old broiler chicks (Ven cob) were divided into four identical groups having four replicates in each group with 12 birds in each replicate and allotted randomly into four dietary treatments viz., T1, T2, T3 and T4. The treatments consisted of a standard broiler ration (T1) containing mineral mixture as per BIS (1992), ration containing mineral mixture without iron (T2), ration containing mineral mixture with iron and supplemental phytase at 750 U/kg diet (T3) and ration containing mineral mixture without iron and supplemental phytase at 750 U/kg diet (T4). Performance parameters such as body weight, weight gain, dry matter consumption, feed efficiency, protein efficiency, tibial weight and tibial ash did not differ significantly between the groups. Significant increase (P<0.05) in the availability of phosphorus with marginal increase in the availability of Fe, Cu and Ca were observed for the groups fed T2 and T3 diets, when compared to other groups. Increased retention of iron in liver of birds fed T2, T3 and T4 diets were observed showing significant difference (P<0.05) with birds fed control diet T1. But the iron retention in spleen did not differ between treatments at sixth and eighth weeks of age. Overall evaluation of the results of the present study reveals that supplementation of inorganic iron through mineral mixtures over and above ingredient iron leads to interaction between Fe and other minerals especially P and Cu. Inclusion of phytase, even though did marginally improve iron retention in storage organs, it did not create significant improvement when added to diets without supplementation of inorganic iron. So it is concluded that levels of 620 to 660 ppm Fe from the ingredients satisfies the requirement for growth, mineral availability and retention in broilers.
