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.

    STUDIES ON BODY CONFORMATION, FIBRE CHARACTERISTICS AND POLYMORPHISM OF KAP 8.2 GENE IN NAGALAND LONG HAIRED GOAT
    (Assam Agricultural University, Khanapara, Guwahati, 2016-07) SHEETAL, J. C. K; Aziz, Abdul
    The present work was undertaken to study body conformation, body weight and important fibre characteristics as well as to identify polymorphism in genomic sequences of KAP 8.2 gene and its association with fibre traits on Nagaland Long Haired Goat of Nagaland. A total of 75 animals of both sex constituted the material of the study for body conformation, body weight and fibre characteristics, whereas polymorphism of KAP 8.2 gene were studied on 25 animals. The pooled averages for length of horn, distance between horns at base, distance between horns at middle, distance between horns at tip, circumference of horn at base, circumference of horn at middle, and circumference of horn at tip were 11.165 ± 0.036, 2.827 ± 0.046, 5.818 ± 0.049, 8.818 ± 0.049, 8.996 ± 0.119, 6.096 ± 0.029, 2.423 ± 0.020 cm respectively in age group G4. The corresponding value for the above traits were 11. 933 ± 0.078, 3.203 ± 0.035, 6.203 ± 0.035, 9.203 ± 0.179, 9.161 ± 0.063, 6.332 ± 0.048, 3.433 ± 0.188 cm respectively in age group G5. The pooled averages for length of head, breadth of head and eye to eye space were 13.766 ± 0.179, 6.742 ± 0.040 and 6.525 ± 0.049 cm respectively in G1; 14.225 ± 0.029, 6.921 ± 0.040, 6.604 ± 0.038 cm respectively in G2; 14.404 ± 0.029, 7.167 ± 0.027 and 7.035 ± 0.134 cm respectively in G3; 14.798 ± 0.031, 7.398 ± 0.028 and 7.766 ± 0.219 cm respectively in G4; 15.280 ± 0.330, 7.611 ± 0.025 and 8.445 ± 0.116 cm respectively in G5. The pooled averages for length of body, height at withers and heart girth were 35.675 ± 0.146, 32.850 ± 0.367 and 36.515 ± 0.170 cm respectively in G1; 38.312 ± 0.205, 36.401 ± 0.241 and 38.066 0.639 cm respectively in G2; 41.363 ± 0.148, 40.446 ± 0.375 and 42.072 ± 0.211 cm respectively in G3; 44.385 ± 0.197, 42.721 ± 0.357 and 46.305 ± 0.265 cm respectively in G4; 47.531 ± 0.406, 44.626 ± 0.308 and 48.450 ± 0.347 cm respectively in G5. The pooled averages for tail length and body weight were 10.208 ± 0.126 cm and 3.625 ± 0.167 kg respectively in G1; 10.941 ± 0.277 cm and 4.683 ± 6.328 kg respectively in G2; 11.424 ± 0.150 cm and 8.211 ± 0.127 kg respectively in G3; 12.161 ± 0.117 cm and 12.369 ± 0.303 kg respectively in G4; 12.991 ± 0.085 cm and 13.812 ± 0.119 kg respectively in G5. The pooled averages for fibre length and fibre diameter were 4.117 ± 0.054 cm and 0.087 ± 0.049 g respectively in G1; 5.242 ± 0.042 cm and 0.099 ± 0.047 g respectively in G2; 5.943 ± 0.095 cm and 0.147 ± 0.028 g respectively in G3; 9.367 ± 0.180 cm and 0.228 ± 0.084 g respectively in G4; 13.245 ± 0.526 cm and 0.228 ± 0.084 g respectively in G5. Genetic variations of KAP 8.2 gene studied on 25 animals (11 male and 14 female) revealed polymorphism. The goats with AB genotype had significantly thicker fibre diameter as compared to those with AA genotype.
