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.

    THEILERIASIS IN CATTLE AND ITS THERAPEUTIC MANAGEMENT
    (College of Veterinary Science, Assam Agricultural University Khanapara, Guwahati-781022, 2017-07) Brahma, Juripriya; Baishya, B. C.
    The study was undertaken w.e.f. 1st March 2016 to 28th February 2017, to study about the theileriasis in cattle and its therapeutic management. A total of 275 out of 563 suspected animals were found positive only for Theileria orientalis infection and the prevalence was recorded 48.84 per cent. Season-wise prevalence of Theileria orientalis was recorded highest in monsoon (53.85%) in comparison to other seasons. The highest prevalence of 60.19 per cent was recorded in the age group of above 3 years. The Holstein Friesian crossbred recorded highest with prevalence of 54.04 per cent. The noted clinical signs were fever, respiratory distress, anorexia, reduced milk yield, nasal discharge, depression, pale mucous membrane, diarrhoea, icterus and changes of urine colour. Though PCR analysis was found more sensitive in detecting the Theileria orientalis infection, the microscopic examination was found as gold standard for diagnosis of clinical theileriasis. The level of haemato-biochemical parameters like haemoglobin, packed cell volume, monocytes, basophils, total erythrocyte count, creatinine and blood urea nitrogen were found significantly decreased (P<0.01), and the levels of total leucocyte count, neutrophils, eosinophils, aspartate aminotransferase, alanine aminotransferase, total bilirubin and direct bilirubin were found significantly increased (P<0.01). Among the different treatment regimens used, the buparvaquone was found most effective and followed by buparvaquone with immunomodulator, oxytetracycline with diminazine diaceturate, and a combination of oxytetracycline and diminazine diaceturate with immunomodulator. Considering the alteration in pre and post treatment parameters like parasitological examination, haemato-biochemical examination and therapeutic efficacy, either the combination of oxytetracycline and diaminazine diaceturate or oxytetracycline, diaminazine diaceturate with immunomodulator also can be used alternatively for the treatment of oriental theileriasis.
