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 PERFORMANCES OF SEXED COMMERCIAL BROILERS AT DIFFERENT DIETARY LEVELS OF PROTEIN
    (Assam Agricultural University, Khanapara,Guwahati, 2016-12) DOLEY, SUSMITA; AHMED, H.F.
    Two hundred seventy numbers of 7 day-old commercial broiler chicks were randomly divided into 3 sexed groups of mixed sex (T1), male (T2) and female (T3) groups of 90 chicks each. Each sexed group was further divided into 3 dietary treatment groups of 30 chicks each viz. T1D1, T1D2, T1D3, T2D1, T2D2, T2D3, T3D1, T3D2 and T3D3. Experimental broilers under these nine treatment groups were offered ad libitum quantities of 3 isocaloric experimental diets containing 3 different levels of protein viz. high protein (D1), medium protein (D2) and low protein (D3) with broiler starter (CP 24.92%, 23.13% and 20.97%) broiler finisher (CP 21.79%, 19.87% and 18.15%) diets from 7 to 21 days and from 22 to 42 days of age respectively. At the end of the 6th week, the mean total body weights were 1836, 1827, 1822, 1943, 1945, 1905, 1684, 1673, 1636g and the mean total weight gains were 1640, 1630, 1626, 1804, 1742, 1645, 1445, 1434 and 1400g for T1D1, T1D2, T1D3, T2D1, T2D2, T2D3, T3D1, T3D2 and T3D3 groups, respectively. The mean total feed intake were 3287, 3252, 3303, 3391, 3380, 3368, 3042, 3039 and 3029g and the average feed conversion ratios were 1.94, 1.93, 1.96, 1.89, 1.88, 1.91, 1.97, 1.99 and 2.03 for T1D1, T1D2, T1D3, T2D1, T2D2, T2D3, T3D1, T3D2 and T3D3 groups, respectively. The percentage retention of nitrogen were 56.33, 60.95, 59.60, 61.78, 66.73, 64.73, 50.77, 56.85 and 54.97, calcium were 46.25, 50.83, 48.19, 51.78, 56.18, 54.85, 42.17, 56.85 and 45.14 and phosphorous were 46.02, 49.12, 47.26, 50.72, 54.91, 53.29, 41.26, 44.72 and 43.16 for T1D1, T1D2, T1D3, T2D1, T2D2, T2D3, T3D1, T3D2 and T3D3 groups, respectively. The mean total dressed weight were 1584, 1580, 1489, 1763, 1748, 1661, 1429, 1403 and1208g, mean total dressing percentage were 71.09, 71.39, 70.76, 72.37, 72.21, 72.12, 71.15, 71.06 and 69.17% and mean total giblet weight were 122.6, 116.1, 103.2, 112.9, 127.1, 106.7, 104.6, 113.4 and 86.50 for T1D1, T1D2, T1D3, T2D1, T2D2, T2D3, T3D1, T3D2 and T3D3 groups, respectively. The mean weight of different cut parts were, neck (110.5, 105.5, 103, 117.5, 120, 112.2, 81.50, 78.50 and 69.0g), wing (183.5, 176.5, 164.0, 193.0, 222.5, 179.4, 160.5, 156.0 and 131.5g), breast (571.0, 564.0, 507.0, 583, 581.5, 538, 484.5, 499 and 437g), thigh (272.5, 276, 265, 314, 314.5, 303, 279.5, 254 and 215.5g), drumstick ( 222.5, 236.5, 227.5, 266.5, 251.5, 261.8, 211, 219 and 184g) and back (224, 221, 220.5, 288, 257.5, 266.4, 211.5, 196.5 and 171g) for T1D1, T1D2, T1D3, T2D1, T2D2, T2D3, T3D1, T3D2 and T3D3 groups respectively. Overall mean serum total protein level were 6.24, 5.76, 5.39, 6.29, 5.86, 5.43, 6.13, 5.64 and 5.20 g/dl, serum albumin were 2.47, 2.59, 2.60, 2.45, 2.77, 2.61, 2.67, 2.62 and 2.39 g/dl and serum globulin were 3.77, 3.18, 2.79, 3.84, 3.09, 2.82, 3.46, 3.02 and 2.81 g/dl for T1D1, T1D2, T1D3, T2D1, T2D2, T2D3, T3D1, T3D2 and T3D3 groups respectively. The body weights were found to be uniform in all the experimental treatment groups at a variation level of 10%. The mean broiler performance efficiency index were 94.74, 94.89, 92.93, 103.10, 103.70, 99.74, 85.10, 83.71 and 79.31 for T1D1, T1D2, T1D3, T2D1, T2D2, T2D3, T3D1, T3D2 and T3D3 groups respectively. The average profit per bird were found to be Rs. 57.84, 66.39, 69.76, 65.44, 74.82, 76.74, 49.13, 55.97 and 57.35 and average profit per kg body weight were found to be Rs. 31.51, 36.36, 38.30, 33.69, 38.47, 40.25, 29.29, 33.60 and 35.21 for T1D1, T1D2, T1D3, T2D1, T2D2, T2D3, T3D1, T3D2 and T3D3 groups, respectively. On the basis of broiler performance efficiency index and economics of production of the present study it may be concluded that male commercial broilers may be reared as single- sex group on diets containing protein levels as per BIS recommendations or even 2% lower to that.
