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.

    GROWTH PERFORMANCE AND CARCASS TRAITS OF ASSAM LOCAL GOATS UNDER INTENSIVE SYSTEM OF MANAGEMENT
    (College of Veterinary Science Assam Agricultural University Khanapara, Guwahati-781022, 2017-07) HOQUE, JEHERUL; Sarma, N. K.
    An experiment was conducted to study the growth response, efficiency of feed conversion, carcass characteristics and meat quality parameter and the cost of production of Assam local goats under different system of management. Twenty goats of one month of age, were randomly selected in village Lachima of Nalbari district, Assam. The goats were randomly divided in two groups comprising of ten kids in each group viz, T0 (Control group) Where goats were reared under extensive system of management with traditional grazing and browsing and T1 (Experimental group) where goats were reared under intensive system of management with ad lib. concentrate and fodder feeding. The average initial (1 month of age) and final (6 months of age) body weight of the goats during the experimental periods under the control and treatment groups were 2.90±0.03 kg and 2.89±0.04 kg and 10.36±0.26 kg and 16.05±0.53 kg respectively. Highly significant difference (P<0.01) in body weight changes were observed between the control and treatment group from 3rd week of the experiment to the 22nd week or till the end of the experiment. The average final body length, height at wither and heart girth of the goats at 6 months of age under the control and treatment groups were 42.44±0.34 and 51.31±1.25, 41.29±0.37 and 49.68±1.06 and 48.29±0.31 and 57.69±1.35 centimetre respectively. Overall changed in body measurement showed highly significant difference between the groups in most of the months. The feed conversion efficiency on DM basis was recorded as 3.49 in the treatment group. No mortality was recorded in both control and treatment group during the experimental period. The average carcass weights in control and treatment groups were 4.89±0.11 and 8.33±0.34 kg respectively, while the dressing percentages were 44.00 and 49.95 in control and treatment group respectively. Highly significant differences (P<0.01) were observed in carcass weight and dressing percentage between control and treatment group. Highly significant difference (P<0.01) was also observed in non-carcass components (weight of heart, drainable blood, fore shank, lung and trachea and skin). Weight of prime cuts (leg, loin, rack, shoulder, breast, flank and neck) also revealed highly significant (P <0.01) difference between control and treatment group. Following sensory assessment, there were highly significant (P<0.01) difference for tenderness, juiciness and overall acceptability. However, significant (P<0.05) differences were observed in flavour and texture between the control and treatment group. The total cost of raising the goats in control and treatment groups were Rs 535.00 and Rs 150.00 while the cost per kg live weight in control and treatment groups were Rs 14.47 and Rs 33.20 respectively. The total incomes by selling meat in control and treatment groups were Rs 1980.00 and Rs 3524.00 respectively. Thus the net income was recorded Rs 1830.00 and Rs 2989.00 in control and treatment groups, respectively.
