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.

In the present investigation, Dipylidium caninum infection was found to be 23.33 per cent on carcass examination, 0.56 per cent on faecal examination and 2.00 per cent of dogs were clinically positive for D. caninum gravid segments. Overall helminthic infection on the basis of carcass examination was 80.00 per cent and 25.55 per cent on faecal examination.
Different flea species Ctenocephalides canis, Ctenocephalides felis felis, Ctenocephalides felis orientis and Xenopsylla cheopis were recorded from dog, cat, mice, goat and cattle. Predominant species in dog was C. felis felis (48.93%) followed by C. felis orientis (40.42%) and C. canis (10.63%). In cat, C. felis felis (50.00%), X. cheopis (27.78%), C. canis (16.67%) and C. felis orientis (5.56%) were recorded. Rate of flea infestation was highest in dog (68.66%) followed by mice (62.50%), cat (24.00%), goat (20.00%) and cattle (13.33%).
Recovery percentage of cysticercoid from dog fleas were 0.65 per cent of which C. canis accounted for 0.26% and C. felis 0.39 per cent.
One species of dog lice Heterodoxus longitarsus was recorded during the study.
Experimental development of metacestode of D. caninum in laboratory bred flea larvae was partly successful under laboratory condition. There was mortality in C. felis felis larvae on exposure to D. caninum eggs in the trial.
