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.

    Performance of broiler chicken fed on diet supplemented with oregano essential oil
    (College of Veterinary Science, Assam Agricultural University, Khanapara Campus, 2022) Borah, Biswajit; Gohain, Anurup Kumar
    An experiment was conducted to study the performance of broiler chickens fed on a diet supplemented with Oregano Essential Oil. For the study, One Hundred eighty (n=180) Day old Broiler chicks of Ven Cobb 430Y strain were randomly divided into four groups (T0, T1, T2 and T3) having 45 chicks per group on the basis of their body weight, the groups were again subdivided into 3 replicates of 15 birds each. The control group was fed with basal diet or the standard pre-starter, starter and finisher diet which were formulated to meet the nutrient requirements as per ICAR, 2013 with the locally available ingredients. And the other three groups were fed with the same basal diet like the CONTROL group but with an additional supplementation of Oregano Essential Oil in the following concentrations: T1 (OEO@200mg/kg basal diet), T2 (OEO@400mg/kg basal diet) and T3 (OEO@600mg/kg basal diet). The experimental results showed significantly (p<0.05) higher change in the body weight, total gain in the body weight, total feed intake and overall feed conversion efficiency in the groups T2 and T1 than the groups T3 and T0. The Broiler Performance Efficiency Index (BPEI) was also higher in the group T2 followed by T1, T3 and T0 respectively. Digestibility of Dry Matter (DM) and retention of nutrients like Nitrogen were found to be significantly (p<0.05) better in the treatment group then the control group. The Dressing percentage (%PSW) was also significantly improved in the treatment groups; T2 was having the highest dressing % followed by T1, T3 and T0. The weight of the Cut Parts (%PSW) was better in the treatment group; however, there was no significant difference. The giblet weight (%PSW) was also not significantly different among the groups. There was no significant (p>0.05) in terms of Total protein, HDL-C, and LDL-C. The blood lipid profile was also not significantly (p>0.05) different among the different treatment groups. And also there was no significant (p>0.05) difference was observed in terms of caecal microbial load. The study revealed that supplementation of Oregano Essential Oil at a concentration of 200mg/kg basal diet improved the net profit of the broiler production. On the basis of all these experimental findings supplementation of OEO @400mg/kg basal diet was found to be better on the growth performance of the broiler chicken.
