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 Assam hill goat reared on periodically disinfected floor
    (College of Veterinary Science, Assam Agricultural University, Khanapara Campus, 2022) Das, Santana; Haque, Adib
    A study was carried out to see the performance of Assam Hill Goat reared on disinfected floors. A total number of 18 Assam Hill Goats (9 males and 9 females) were selected and divided into 3 groups; each consists of 6 goats of an equal number of males and females which were intensively housed. The 3 groups were randomly assigned to the following treatments, viz. floor without any disinfectant treatment (T1), floor treated with sodium hypochlorite (T2) and floor treated with calcium oxide i.e. quicklime (T3). The fortnightly average initial body weight of the selected goats of T1, T2 and T3 groups were 6.01 ± 0.16, 6.23 ± 0.16 and 6.21 ± 0.17 kg respectively and the corresponding value for the same groups at 6th fortnight were 10.45 ± 0.17, 11.93 ± 0.23 and 11.38 ± 0.22 kg respectively. Statistical analysis of the data exhibited significant differences among the groups from the 4th to 6th fortnight (P<0.05). Goats reared on a floor treated with sodium hypochlorite showed higher body weight followed by calcium oxide treated floor during the entire experimental period, however, the difference appeared to be non-significant up to 3rd fortnight. The critical difference test reveals that there was a significant difference between T1 and T2 groups but no significant difference could be observed between T1 and T3 as well as T2 and T3 groups. The body weight gains of goats for T1, T2 and T3 groups in the 1st fortnight figured as 0.52 ± 0.09, 0.60 ± 0.08 and 0.57 ± 0.08 kg and the corresponding values for the same 3 groups in the 6th fortnight were recorded as 1.14 ± 0.11, 1.54 ± 0.10, and 1.37 ± 0.10 kg respectively. The average daily body weight gain of goats for T1 was 0.035 ± 0.005 kg, T2 was 0.040 ± 0.006 kg and T3 was 0.038 ± 0.005 kg in the 1st fortnight and the corresponding values for the same groups in the 6th fortnight were recorded as 0.076 ± 0.007 kg, 0.100 ± 0.006 kg, and 0.091 ± 0.006 kg respectively. The fortnightly body weight gain and daily body weight gain manifested a significant difference (P<0.05) statistically in 6th fortnight. The critical difference test reveals that there was a significant difference between T1 and T2 groups but found no significant difference between T1 and T3 as well as T2 and T3 groups. The average dry matter intake of goats in T1, T2 and T3 were 4.05 ± 0.113, 4.48 ± 0.120 and 4.37 ± 0.117 kg in the 1st fortnight respectively and the corresponding values for the same 3 groups in the 6th fortnight were recorded as 6.59 ± 0.101, 7.51 ± 0.174, and 7.34 ± 0.163 kg respectively. There was a statistically significant difference (P<0.05) from 4th to 6th fortnight and the critical difference test revealed a significant difference between T1 and T2 groups but could not exhibit any significant difference between T1 and T3 as well as T2 and T3 groups. The feed conversion ratios for T1, T2 and T3 goats in the 1st fortnight figured as 7.80 ± 0.18, 7.38 ± 0.17 and 7.65 ± 0.18 and the corresponding values for the same 3 groups in the 6th fortnight were 5.80 ± 0.12, 4.88 ± 0.10 , and 5.36 ± 0.11 respectively. The feed conversion ratio was found to be highly significant (P<0.01) from 4th to 6th fortnight. This revealed that feed was more efficiently utilized for growth by the goats reared on sodium hypochlorite treated floor (T2). The critical difference test reveals that there was a significant difference between T1 and T2 groups in 4th fortnight but no such differences could be seen between T1 and T3 as well as T2 and T3 groups. But from 5th fortnight onwards there was a significant difference among all the three groups. The incidence rate of diarrhea of goats was recorded as 40% for T1, 18% for T2 and 40% for T3 in the 1st fortnight. No incidence of diarrhea was observed from 4th fortnight onwards in all the groups. The data expressed that the overall diarrhea incidence rate was higher in T1 goats intermediate in T3 and lowest in T2. The parasitic infestation of goats was recorded as 83% in T1, 66% in T2 and 83% in T3 groups in the 1st fortnight. The data further reveals that the overall parasitic infestation of goats was found to be lowest in T2 goats followed by T3 and T1.
