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 FEEDING GINGER (ZINGIBER OFFICINALE) ROOT POWDER ON GROWTH PERFORMANCE, CARCASS CHARACTERISTICS AND BLOOD BIOCHEMICAL PARAMETERS IN BROILER CHICKENS
    (College of Veterinary Science, Assam Agricultural University Khanapara, Guwahati-781022, 2017-07) Das, Pranjal; Talukdar, J. K.
    A total of one hundred eighty day old commercial broiler chicks (Cobb-400 Y) having similar body weight from a single hatch were procured to study the effect of feeding ginger (Zingiber officinale) root powder on some economic parameters in broiler chickens. The chicks were randomly divided into four groups viz.T0, T1, T2 and T3 containing 45 chicks in each group. Each group was further subdivided into 3 replicates of 15 chicks in each group. The birds under T0 group were offered basal diet without addition of ginger powder, while the birds under T1, T2 and T3 groups were given ginger powder with feed at the rate of 1.5, 2.0 and 2.5 % level respectively and used in the feeds of broiler chickens for a period of six (6) weeks. All the birds of four groups were offered ad libitum feed and water and maintained under uniform managemental condition. The total feed consumption per broiler for different experimental groups was the highest in T0 group (4011.11g) and was the lowest in T3 group (3924.44g).The final body weight per broiler was the highest in T2 group (2268.22 + 3.02g) and was the lowest in T0 (1890.22 + 4.32g) group. The overall feed conversion ratio for the entire period was the best in T2 group (1.59), followed by T1 (1.64), T3 (1.68) and T0 (1.84) groups. The broiler performance efficiency index was the highest in T2 (142.65) group and was the lowest in T0 (165.86). The livability per cent was 100% for the T1 and T2 groups, followed by T3 (97.77%) and T0 (95.55%). The cost of production per broiler including the additional cost of ginger powder and gross profit were the highest in T2 (Rs. 182.19 and Rs.32.50) and were the lowest in T0 (Rs. 165.86 and Rs. 13.68) group. All carcass traits (dressed weight, giblet weight and giblet yield) except dressing percentage differed significantly among different experimental groups. The dress weight (1636.40 + 21.44 g), giblet weight (120.20 + 1.35 g) and giblet yield (5.35 + 0.02%) found to be higher in T2 group of birds. The control group of birds (T0) had the lower values for all these carcass traits. The per cent yield of cut-up parts like wing, back, breast and drumstick except neck and thigh differ significantly among different treatment groups. The per cent weight of wings (12.75 + 0.31), back (19.71 + 0.49), breast (25.05 + 0.45) and drumstick (14.92 + 0.52) found to be higher in T2 group of birds. The per cent weights of relative organs of broiler on dressed weight basis did not differ significantly among different treatment groups, except the per cent weight of abdominal fat. The per cent weight of abdominal fat was significantly decreased in T3 group (0.51 +0.06) followed by T2, T1 and T0 groups. Among the biochemical parameters serum glucose, total serum cholesterol, triglyceride, and LDL had significantly lower values in T3 group, followed by T2, T1 and T0 groups. The HDL values increases significantly in T3 group, followed by T2, T1 and T0 groups. All the haematological parameters except haemoglobin and PCV recorded in the present study did not differ significantly among different treatment groups. The haemoglobin values significantly higher in T3 and T2 groups (11.75 +0.07 and 11.51 + 0.20) as compared to T1 and T0 (10.23 + 0.10 and 9.82 + 0.01) groups. The PCV values increases significantly in T3 group (28.46 + 0.04) followed by T2 (26.65 + 0.06), T1 (25.06 + 0.29) and T0 (22.32 + 0.12) groups. The result of present study indicated that the ginger powder can be used economically as a natural feed additive in broiler chicken diet at the level of 2.0% to improve the overall performance of commercial broiler chickens.
