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.

    Clinico-haematobiochemical and therapeutic management of anaemia associated with Chronic Kidney Disease (CKD) in dogs
    (College of Veterinary Science, Assam Agricultural University, Khanapara Campus, 2022-09) Hazarika, Pradyout Pallav; Changkija, Bendangla
    The present study entitled “CLINICO-HAEMATOBIOCHEMICAL AND THERAPEUTIC MANAGEMENT OF ANAEMIA ASSOCIATED WITH CHRONIC KIDNEY DISEASE (CKD) IN DOGS” was done for a period of 10 months viz. from October 2021 to July 2022 with the objectives to study the prevalence of anaemia and associated clinical and haemato-biochemical alterations in dogs presented at Veterinary Clinical Complex (VCC), College of Veterinary Science, Khanapara, Assam, and to evaluate the comparative therapeutic efficacy of recombinant human erythropoietin (rHuEPO) and parenteral iron alone or in a combination along with conservative therapy in anaemic dogs associated with CKD. The study revealed overall prevalence of 43.55% anaemia with higher prevalence in Mongrel (56.13%), male predominance (47.12%) and in age group of >6-10 years (64.63%). Clinical signs associated with anaemia were hypothermia, tachycardia, tachypnoea, pale mucous membrane, increased capillary refill time, anorexia, diarrhoea, halitosis, dental tartar and melena. Haemato-biochemical assessment revealed a normocytic normochromic anaemia with a significant decrease in the values of Hb, PCV and TEC in anaemic dogs. Hypoproteinemia and hypoalbuminemia with a significantly increased BUN, serum creatinine, ALT, AST and total bilirubin were also observed in anaemic dogs. The prevalence of anaemia associated with CKD was found to be 3.11%. Nephrosonogram of affected dogs revealed hyperechoic and hypoechoic thick renal cortices with partial to complete loss of cortico-medullary differentiation along with hyperechoic medullary rim, mild to complete loss of renal parenchyma and moderate to complete capsular disorientation. Proteinuria along with significant elevation in UPCR and significant decrease in urine creatinine was recorded in affected dogs. Haematobiochemical assessment revealed normochromic normocytic anaemia, hyperproteinemia, hyperalbuminemia and hyperphosphatemia along with significant elevation of BUN, serum creatinine, ALT, AST and total bilirubin in anaemic dogs associated with CKD. Combination of rHuEPO and parenteral iron along with conservative therapy was found to be more effective in the therapeutic management of anaemia associated with CKD with a survival rate of 75% (28 days) when compared to rHuEPO and parenteral iron given alone along with conservative therapy.

    Sub-clinical mastitis in dairy cow and its therapeutic management
    (College of Veterinary Science, Assam Agricultural University, Khanapara Campus, 2022-09) Kafle, Gaurab; Baishya, Bhaben Chandra
    The present study entitled “SUBCLINICAL MASTITIS IN DAIRY COW AND ITS THERAPEUTIC MANAGEMENT” was done for a period of 8 months viz. from December 2021 to July 2022 with the objectives to study the prevalence, etiology, diagnosis of subclinical mastitis (SCM), antibiogram of the isolates and to evaluate the therapeutic efficacy of three different treatment regimen on SCM in dairy cows in private dairy farms located in and around Guwahati city. Total 508 quarter milk samples from 127 dairy cows were screened for SCM by Modified California mastitis test (MCMT) and recorded animal wise, quarter wise prevalence as 67.71 and 28.34 per cent, respectively. Age wise prevalence was recorded highest in cows aged between >5-7 years (70 per cent), whereas lactation wise prevalence was recorded highest in the cows in fourth lactation (72.72 per cent) and least in first lactation (58.82 per cent). Similarly, prevalence of SCM was found higher in late stage of lactation (71.42 per cent) as compared to mid (70.45 per cent) and early stage of lactation (60.97). The right hind quarter (33.07 per cent) and the left hind quarter (28.34 per cent) were mostly affected as compared to other two quarters. The quarter wise prevalence of subclinical mastitis was recorded highest in single quarter followed by two quarters, four quarters and least in three quarters with 33.07 per cent, 28.34 per cent, 4.7 per cent, and 1.57 per cent respectively. A total of 164 bacterial isolates were obtained from 508 quarter milk samples, Staphylococcus spp. was found as the most prevalent organism (65.24 per cent) followed by Streptococcus spp. (9.14 per cent), Escherichia coli (32.31 per cent) and Klebsiella spp. (1.82 per cent). Enrofloxacin was found to be most effective antimicrobial drug against the isolates followed by ceftriaxone, cefaperazone, oxytetracycline and amoxicillin. Before treatment mean values of SCC and pH in group A, B and C were significantly high (P<0.001) when compared to healthy control group, whereas fat and SNF were significantly (P<0.001) low. However, after therapy the mean value of SCC and pH were significantly (P<0.001) decreased whereas, fat and SNF increased significantly (P<0.001). Therapeutic regimen of group A viz. HTM injection (A, E and iodine) along with antibiotic therapy was found more effective and helped the affected cows to recover early as compared to group B viz. Levamisole HCl and antibiotic and group C viz. mineral mixture and antibiotic.
