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.

    PERFORMANCE OF INDIGENOUS CHICKEN IN CERTAIN DISTRICTS OF ASSAM UNDER BACKYARD FARMING SYSTEM
    (College of Veterinary Science, Assam Agricultural University, Khanapara, Guwahati, 2021-12) ISLAM, JEHIRUL; Ferdoci, A. M.
    The study was conducted on indigenous chickens of Darrang and Udalguri district of Assam to evaluate growth, performance and reproductive traits. Data on body weights relating to 747 birds were used in the study. The data of 115, 137 and 95 number of birds were utilized for age at first egg, annual egg production and reproductive traits respectively. Fifty eggs were randomly collected for the study of egg quality traits. Data were collected during the period from August, 2020 to June, 2021 through field survey and interviewed the farmers with pre-tested questionnaire. The overall least-squares means of body weight at day old stage, 20 weeks and 40 weeks were found to be 28.332±0.218, 745.719±4.479 and 1296.984±6.971 g respectively. The body weight of males at 20 weeks and 40 weeks were found to be 779.924±7.995 g and 1389.121±11.670 g and the corresponding values of females were found to be 711.513±5.407 g and 1204.846±8.691 g respectively. Chicken of Darrang district had higher body weight of 29.002±0.304, 750.310±6.215 and 1302.030±9.596 g at day old stage, 20 and 40 weeks of age than Udalguri district with 27.662±0.314, 741.128±6.461 and 1291.938±10.142 g respectively. Significant effect of district on body weight at day old stage (P<0.01), 20 weeks (P<0.05) and 40 weeks (P<0.01) were observed. The overall least-squares means for age at first egg was found to be 199.286±4.236 days. The least-squares means for age at first egg in Darrang and Udalguri district were 196.741±7.986 and 201.831±9.022 days respectively which were found to be non-significant. The overall least-squares means for annual egg production was found to be 65.236±0.813 numbers. The least-squares means for annual egg production in Darrang and Udalguri district were 67.901±1.137 and 65.570±1.162 numbers respectively which were found to be significant (P<0.01). The overall mean for egg weight (g), Albumen index, Yolk index, Haugh unit, Shell thickness (mm) and Shape index were recorded as 40.54±0.63, 0.077±0.003, 0.502±0.006, 70.213±0.700, 0.323±0.003 and 75.725±0.407 respectively. The egg shell colours were mostly light brown followed by creamy white. The average fertility and hatchability were recorded as 90.75 % and 87.42 % respectively.
