Assam Agricultural University, Jorhat

Assam Agricultural University is the first institution of its kind in the whole of North-Eastern Region of India. The main goal of this institution is to produce globally competitive human resources in farm sectorand to carry out research in both conventional and frontier areas for production optimization as well as to disseminate the generated technologies as public good for benefitting the food growers/produces and traders involved in the sector while emphasizing on sustainability, equity and overall food security at household level. Genesis of AAU - The embryo of the agricultural research in the state of Assam was formed as early as 1897 with the establishment of the Upper Shillong Experimental Farm (now in Meghalaya) just after about a decade of creation of the agricultural department in 1882. However, the seeds of agricultural research in today’s Assam were sown in the dawn of the twentieth century with the establishment of two Rice Experimental Stations, one at Karimganj in Barak valley in 1913 and the other at Titabor in Brahmaputra valley in 1923. Subsequent to these research stations, a number of research stations were established to conduct research on important crops, more specifically, jute, pulses, oilseeds etc. The Assam Agricultural University was established on April 1, 1969 under The Assam Agricultural University Act, 1968’ with the mandate of imparting farm education, conduct research in agriculture and allied sciences and to effectively disseminate technologies so generated. Before establishment of the University, there were altogether 17 research schemes/projects in the state under the Department of Agriculture. By July 1973, all the research projects and 10 experimental farms were transferred by the Government of Assam to the AAU which already inherited the College of Agriculture and its farm at Barbheta, Jorhat and College of Veterinary Sciences at Khanapara, Guwahati. Subsequently, College of Community Science at Jorhat (1969), College of Fisheries at Raha (1988), Biswanath College of Agriculture at Biswanath Chariali (1988) and Lakhimpur College of Veterinary Science at Joyhing, North Lakhimpur (1988) were established. Presently, the University has three more colleges under its jurisdiction, viz., Sarat Chandra Singha College of Agriculture, Chapar, College of Horticulture, Nalbari & College of Sericulture, Titabar. Similarly, few more regional research stations at Shillongani, Diphu, Gossaigaon, Lakhimpur; and commodity research stations at Kahikuchi, Buralikson, Tinsukia, Kharua, Burnihat and Mandira were added to generate location and crop specific agricultural production packages.

    EFFECT OF DIETARY SUPPLEMENTATION OF CYSTEINE-PROTEASE AND 1,4-β-XYLANASE AND THEIR COMBINATION IN LOW PLANE OF NUTRITION ON GROWTH PERFORMANCE OF COMMERCIAL BROILER CHICKEN
    (College of Veterinary Science, Assam Agricultural University, Khanapara, Guwahati, 2021-12) ALI, MOKADESH; Saikia, Gunaram
    An experiment was conducted to study the effect of dietary supplementation of cysteine- protease and 1,4-β-xylanase and their combination in low plane of nutrition on growth, nutrient utilization, blood biochemical profile, carcass characteristics and to evaluate economics of feeding in commercial broiler chicken. One hundred sixty (N=160) commercial broiler chicks (Vencobb 400) were randomly distributed into 4 groups (T0, T1, T2 and T3) on live weight basis comprising of 40 chicks in each group with four replicates of 10 chicks in each. The control group (T0) was fed with a standard pre-starter, starter and finisher broiler ration as per ICAR (2013) specifications. The chicks belong to group (T1) was fed with standard ration but supplemented with cysteine-protease (32500 PU/kg of feed) and 1,4-β-xylanase (16000 BXU/kg of feed) as per recommended dose of manufacturer. Birds belong to group T2 and T3 were fed rations with 4 and 6 percent lower crude protein (CP) and metabolizable energy (ME) content than ICAR (2013) specifications, respectively with supplementation of both cysteine-protease (32500 PU/kg of feed) and 1,4-β-xylanase (16000 BXU/kg of feed) in all pre-starter, starter and finisher phases. At the end of pre-starter, starter and finisher phases blood samples were collected and analysed for blood biochemical parameters. Four birds from each group were slaughtered to study the carcass characteristics and chemical composition of meat. The economics of feeding and broiler production were evaluated. Highly significant (p0.05) differences were observed in total feed intake, retention of calcium and phosphorus, dressing percentage, yield of prime cuts, yield of lymphoid organs, chemical composition of meat, serum total protein, albumin, globulin and gamma glutamyl transferase level. Cost of production when calculated revealed that supplementation of cysteine-protease and 1, 4-β-xylanase in broiler rations was more profitable than feeding diets without enzymes. The highest gross profit was observed in group T1 receiving standard rations as per ICAR (2013) specifications supplemented with cysteine-protease and 1, 4-β-xylanase. Hence, the study indicated that broilers could be reared more economically and profitably on broiler rations supplemented with cysteine-protease and 1, 4-β-xylanase.
