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 SUPPLEMENTATION OF ACIDIFIER ON THE PERFORMANCE OF BROILER CHICKEN
    (College of Veterinary Science, Assam Agricultural University, Khanapara, Guwahati, 2022-02) DUTTA, RUPJYOTI; Bhuyan, Robin
    One hundred twenty day old broiler chick of uniform body weight were divided into 4 different groups of 15 chick each viz. T0, T1, T2 and T3. Birds in all group were offered broiler starter (CP 21.5% and 3056 ME Kcal) and broiler finisher (CP 19.5% and 3100 ME/kg diet) from 0-21 days and from 22-42 days of age respectively. No acidifier was added in the diet of T1 group i.e. control group. The other three groups were fed acidifier in the diet @ 0.1% At the end of 6th week, the average body weight was 2168.37, 2209.17, 2107.53 and 1883.57 and the average total body weight gain was 1906.20, 2154.90, 2029.20 and 1821.30 for T0, T1, T2 and T3 group respectively. The average daily gain was 49.86, 51.31, 48.31 and 43.36 for T0, T1, T2 and T3 groups respectively. The average total feed intake was 3447.82, 3544.42, 3627.23 and 3560.33 and the average feed conversion was 1.73, 1.65, 1.78 and 1.97 for T0, T1, T2 and T3 group. The average weekly protein efficiency rate was 2.99, 3.15, 2.94 and 2.62 for T0, T1, T2 and T3 group. The percentage of retention of nitrogen was 69.21, 70.46, 69.08 and 69.19 calcium was 62.72, 62.57, 61.46, 60.46 and phosphorous was 48.01, 49.19, 49.19 and 50.01 for T0, T1, T2 and T3 group. The average dressing percentage was 73.71, 74.19, 73.40 and 68.45 and total giblet weight percentage were 3.12, 3.06, 3.16 and 3.17 for T0, T1, T2 and T3 group respectively. Meat compositions showed that moisture percentage was 73.62, 73.35, 74.32 and 74.80 for T0, T1, T2 and T3 group respectively. The protein and fat percentage in meat was 18.84, 19.26, 18.82, 17.08 and 6.34, 6.62, 6.28 and 6.04 and 0.75, 0.80, 0.79, 0.74 for ash. Overall mean concentrations of serum protein, blood glucose level, serum calcium and serum inorganic phosphorous was 3.84, 3.87, 3.78, 3.75, 188.62, 187.46, 184.14, 184.78, 5.22, 6.88, 6.62, 6.58 and 5.43, 5.55, 5.50, 5.63 respectively. The cost of feeding per kg body weight gain was Rs. 62.16, 58.16, 60.92, 70.21. The cost of feed was cheaper in T1 and T2 as compared to T0 and T3 group. On the basis of the above results of the present study it can be concluded that supplementation of acidifier in broiler diet with normal protein and energy diet as per (ICAR 2013) is advantageous for broiler production.
