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.

    Effect of wet and boiled diets feeding on growth and carcass characteristics in crossbred hampshire pigs
    (College of Veterinary Science, Assam Agricultural University, Khanapara Campus, 2023) Kakati, Lakshya Jyoti; Bora, J R
    A total of 36 (thirty six) weaned Hampshire crossbred pigs were selected randomly from the littermates of 6-8 piglets maintained at the “Ruhini Deka Pig Farm” complex. The pigs (56 days old) were randomly divided into three treatment groups depending upon nearness of body weight in such a manner that each group consisted of twelve piglets with equal number of males and females. The animals were allotted to 3 experimental groups viz., control (reared on standard conventional feed), T1 (reared on standard conventional wet feed @ the ratio of 1:1.5) and T2 (reared on standard conventional boiled /cooked feed). Weaned piglets were housed individually under conventional housing system up to the market age (32 weeks). The space allowance per pig was provided 10 x 9 ft. (approx.). The standard conventional feed both grower and finisher feed were prepared as per ICAR (2013) recommendation. Feed was offered in the morning and evening. Clean and wholesome water was provided round the clock throughout the experiment. At the end of the experiment, 3 animals per treatment (the lightest, heaviest and the middle by weight) were selected for slaughter by humane method. Boiled diet could significantly (p<0.05) influence body weight, total and average daily feed intake of crossbred Hampshire pigs. However, average daily gain was not found to be significant during the experimental period yet the findings clearly shows numerical superiority in regards to body weight, average daily gain, total and average daily feed intake. FCE was found to be the best in boiled fed (T2) group showing better efficiency over control and wet fed (T1) group. Moisture (P<0.01) was affected by soaking and boiling of feed, while crude protein, crude fibre, ether extract, total ash and showed no significant difference. Boiling of feed (grower-finisher) showed significant change (p<0.01) in the phosphorus content of the experimental ration. The pre-slaughter weight, hot carcass weight and dressing percentage, carcass measures viz., Carcass length, backfat thickness and loin eye area was not affected. Wholesale cuts (ham, bacon, loin, boston butt and picnic) did not show any significant difference (p>0.05) among the groups. Likewise there was no significant difference (p>0.05) in regards to weight of the edible and inedible offals among the treatment groups. In relation to physico-chemical properties, water holding capacity and ultimate pH at 6 hours of L. dorsi showed no significant (P>0.05) difference among the groups. On sensory evaluation of pork, flavour and juiciness revealed significant difference among the groups while colour, texture and overall acceptability of pork showed no difference among the experimental groups. However, the present findings showed numerical superiority among the groups in regards to sensory parameters. The cost feeding per kg weight gain was found to better at the end of the feeding trial slightly in the boiled fed (T2) group followed by we fed (T1) and control group. Therefore, it may be concluded that feeding of boiled feed may be suggested for improved productive performance, feed conversion efficiency, superior carcass and pork quality characteristics and better cost of production.
