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.

    ANTHELMINTIC ACTIVITY OF Acorus calamus RHIZOME EXTRACT AGAINST Haemonchus SPECIES IN GOATS
    (College of Veterinary Science, Assam Agricultural University, Khanapara, Guwahati, 2022-01) SHARMA, CHAMPA; Changkija, Bendangla
    The present investigation was carried out with the view to study the anthelminitic activity of Acorus calamus rhizome extract against Haemonchus species in goats. Haemonchus contortus worms were found to be the predominant worm in the goat population of the farm. The qualitative phytochemical analysis of hydroethanolic extract of Acorus calamus rhizome revealed the presence of terpenoids, steroid, diterpines, flavonoids, tannin, glycoside, saponin and phenolic compound. In in-vitro study, Haemonchus worms were exposed to different concentration of hydroethanolic and aqueous extract of Acorus calamus rhizome. The hydroethanolic extract was found to be more effective against Haemonchus contortus than aqueous extract. A dose dependant anthelmintic activity was exhibited by rhizome extract and highest efficacy was observed at 1000 μg/ml. The goats positive for Haemonchosis showed a significant decrease in Hb, PCV, TEC, total serum protein, albumin A:G ration and serum iron and a significant increase in TLC, neutrophil and eosinophil percentage and liver enzymes (ALT and AST). In-vivo anthelmintic study of hydroethanolic extract of Acorus calamus rhizome @ 500 mg/kg b.wt. orally (two doses, 0 day and 21st day) and fenbendazole @ 5 mg/ kg b.wt. orally were given to Haemonchus infected goats. EPG count, haemato-biochemical parameters and clinical improvement were evaluated on ‘0’, 7th, 14th, 21st and 28th day post treatment. In Group I, EPG became 0 on 28th day after administration of second dose on 21st day. In Group II, treated with fenbendazole, EPG count became 0 on 7th day. Haematological parameters showed increase in Hb, PCV, TEC, lymphocyte % and decrease in TLC, neutrophil and eosinophil % post treatment and biochemical analysis showed increase in values of TSP, Serum Albumin, A:G ratio and Serum Iron after treatment. Globulin, ALT and AST values decreased significantly post treatment. On the basis of reduction of EPG count and haemato-biochemical changes, the therapeutic efficacy of hydroethanolic extract of Acorus calamus rhizome was 100% on 28th day post treatment with administration of second dose orally on 21st day. Fenbendazole showed a higher efficacy with 100% reduction of EPG on 7th day post treatment.
