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 ANTHELMINTIC EFFICACY OF Zanthoxylum armatum AGAINST GASTROINTESTINAL PARASITES OF GOAT
    (College of Veterinary Science, Assam Agricultural University, Khanapara, Guwahati, 2022-01) HUSSAIN, JAKIR; Dutta, T. C.
    The present investigation was carried out to study the anthelmintic efficacy of hydroethanolic seed extract of Zanthoxylum armatum against gastrointestinal parasites of goats. The overall prevalence of gastrointestinal parasites in goats was recorded to be 65.41% under prevailing agro-climatic conditions of Goat Research Station, AAU, Burnihat and private farms in and around Guwahati city, Assam from January- March 2021 & September - November 2021.Out of the different gastrointestinal parasites recorded in goats the prevalence of Haemonchus spp. (54.14%) was found to be the highest and Trichostrongylus spp. (18.78%) the lowest. In most of the animals, mixed infestations with 2-3 types of gastrointestinal parasites were also recorded. Phytochemical analysis of hydroethanolic seed extract of Zanthoxylum armatum revealed the presence of alkaloid, terpenoid, diterpene, flavonoid, steroid, glycosides, saponin and phenolic compounds but it was found negative for tannin. The acute oral toxicity study in mice showed that the hydroethanolic seed extract of Zanthoxylum armatum is safe up to 2000 mg/kg body weight when administered orally. In-vitro study of hydroethanolic seed extract of Zanthoxylum armatum showed dose-dependent and time-dependent anthelmintic activity and the highest efficacy was observed at 1000 μg/ml against adult parasite of Haemonchus contortus at 60 minutes. Based on the reduction of EPG count in the present study, Group A, animals which were treated with hydroethanolic seed extract of Zanthoxylum armatum @250 mg/kg body weight, orally and repeated on the 21st day showed the highest efficacy on post-treatment days i.e. 100% on the 28th day followed by the animals in Group C, treated with hydroethanolic seed extract of Zanthoxylum armatum @125 mg/kg body weight and ethanolic seed extract of Butea frondosa @ 50 mg/kg body weight, Group B,treated with hydroethanolic seed extract of Zanthoxylum armatum @125 mg/kg body weight and methanolic seed extract of Entada phaseoloides @250 mg/kg body weight and Group D, treated with hydroethanolic seed extract of Zanthoxylum armatum @125 mg/kg body weight, methanolic plant extract of Entada phaseoloides @250 mg/kg body weight and ethanolic seed extract of Butea frondosa @50mg/kg body weight, orally and repeated on 21st day. The In-vivo study showed that the hydroethanolic seed extract of Zanthoxylum armatum individually or in combination with methanolic seed extract of Entada phaseoloides and ethanolic seed extract of Butea frondosa were effective against gastrointestinal parasites of goats. Based on the improvement in body weight and haemato-biochemical parameters with reduction of EPG of faeces it was observed that hydroethanolic seed extract of Zanthoxylum armatum was more effective as anthelmintic when used alone than in combination against gastrointestinal parasites of goats.
