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.

    PREVALENCE OF GASTROINTESTINAL NEMATODOSIS IN CATTLE WITH SPECIAL REFERENCE TO Strongyles AND ITS THERAPEUTIC MANAGEMENT
    (College of Veterinary Science, Assam Agricultural University Khanapara, Guwahati-781022, 2016-12) Rai, Astuti; Kalita, D. N.
    The present study was conducted on prevalence of Gastrointestinal Nematodosis in cattle with special reference to Strongyles and its therapeutic management in different places of Assam, during the period from May 2015 to April 2016 for a period of one year with the objectives (i) to study prevalence of Gastrointestinal nematodes specially Strongyle infection in cattle, (ii) to study the haemato-biochemical changes in affected cattle and (iii) to find out comparative efficacy of some anthelmintics against Strongyle infection. A total of 1154 faecal samples collected from cattle of different places of Assam, were examined for detection of nematodes eggs, of which 271 cattle resulted positive for nematode eggs and the overall prevalence was recorded as 23.46 per cent. Out of 23.46 per cent, the percent prevalence of different nematodes i.e. Strongyle spp., Strongyloides spp., Trichuris spp. and Toxocara vitulorum were recorded as 9.27, 1.55, 1.99 and 10.65 per cent respectively. The season-wise prevalence was found to be highest (13.62 %) in monsoon season and lowest (5.47%) in pre-monsoon season. The highest prevalence of 15.23 per cent was recorded in cattle below 1 years and lowest prevalence of 5.35 per cent was recorded in cattle of 3 year above. A significant difference (P<0.05) in the variation in season-wise and age-wise prevalence was revealed The sex-wise prevalence was higher (10.46%) in female cattle than in male (7.73%).The breed-wise prevalence higher (10.59%) in local cattle than cross-bred (7.31%) cattle. There were no significant (P>0.05) difference in variation of sex and breed-wise prevalence. Out of the Strongyle positive cattle, 18 cattle, irrespective of breed, age and sex, were selected randomly and divided into 3 groups viz., Grpup I, Group II and Group III, each consisting 6 cattle. Another 6 healthy cattle were kept as healthy control and named as Group IV. In group I, cattle were treated with albendazole at the dose rate of 7.5 mg/kg body weight .orally for single dose, in group II, cattle were treated with ivermectin at the dose rate of 0.2 mg/kg body weight subcutaneously for single dose and in group III, cattle were treated with fenbendazole at the dose rate of 7.5 mg/kg body weight for single dose. Supportive therapy with mineral mixure (Minfa powder), antidiarrhoel (Diaroak) and 5 % dextrose were given to all the cattle in group I, II and III. During pre-treatment period, the haemato-biochemical study revealed a significant decrease in the levels of Hb, PCV, TEC, Lymphocytes and Monocyte in the affected cattle which increased gradually after anthelmintics treatment whereas an increase in the levels of TLC, Eosinophils and Neutrophils were observed in the affected cattle which also decreased gradually after treatment and reached normal level Based on reduction of EPG count, haemato-biochemical changes and recovery from clinical signs, the therapeutic efficacy was found to be highest (91.53%) with albendazole followed by fenbendazole (86.93%) and ivermectin (82.78%) in this study.
