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.

    GENETIC STUDIES ON GROWTH PERFORMANCE OF CROSSBRED PIGS
    (College of Veterinary Science, Assam Agricultural University, Khanapara, Guwahati, 2022-01) Rongpi, Racy; Ferdoci, A. M.
    The present study was carried out in 1025 piglets belonging to two genetic groups viz. Hampshire crossbred and crossbred of Tamworth and Desi (TND) pigs that were being bred and maintained at the Regional Pig Breeding Farm, Kyrdemkulai, Meghalaya. Performance records of 379 and 646 piglets born to 136 gilts/dams and 25 sires belonging to the two genetic groups during the year 2016-2019 were studied with a view to assess the genetic and phenotypic parameters of growth traits viz. body weights at different ages and daily body weight gains during pre-weaning and post-weaning periods. The overall least-squares means for body weight(kg) at birth, 4th week, 8th week, 12th week, 16th week, 20th week and 24th week of age were found to be 1.247±0.007, 5.615±0.013, 11.302±0.032, 17.246±0.029, 23.349±0.053, 30.584±0.064 and 38.528±0.057 respectively.

    (College of Veterinary Science, Assam Agricultural University, Khanapara, Guwahati, 2021-12) ISLAM, JEHIRUL; Ferdoci, A. M.
    The study was conducted on indigenous chickens of Darrang and Udalguri district of Assam to evaluate growth, performance and reproductive traits. Data on body weights relating to 747 birds were used in the study. The data of 115, 137 and 95 number of birds were utilized for age at first egg, annual egg production and reproductive traits respectively. Fifty eggs were randomly collected for the study of egg quality traits. Data were collected during the period from August, 2020 to June, 2021 through field survey and interviewed the farmers with pre-tested questionnaire. The overall least-squares means of body weight at day old stage, 20 weeks and 40 weeks were found to be 28.332±0.218, 745.719±4.479 and 1296.984±6.971 g respectively. The body weight of males at 20 weeks and 40 weeks were found to be 779.924±7.995 g and 1389.121±11.670 g and the corresponding values of females were found to be 711.513±5.407 g and 1204.846±8.691 g respectively. Chicken of Darrang district had higher body weight of 29.002±0.304, 750.310±6.215 and 1302.030±9.596 g at day old stage, 20 and 40 weeks of age than Udalguri district with 27.662±0.314, 741.128±6.461 and 1291.938±10.142 g respectively. Significant effect of district on body weight at day old stage (P<0.01), 20 weeks (P<0.05) and 40 weeks (P<0.01) were observed. The overall least-squares means for age at first egg was found to be 199.286±4.236 days. The least-squares means for age at first egg in Darrang and Udalguri district were 196.741±7.986 and 201.831±9.022 days respectively which were found to be non-significant. The overall least-squares means for annual egg production was found to be 65.236±0.813 numbers. The least-squares means for annual egg production in Darrang and Udalguri district were 67.901±1.137 and 65.570±1.162 numbers respectively which were found to be significant (P<0.01). The overall mean for egg weight (g), Albumen index, Yolk index, Haugh unit, Shell thickness (mm) and Shape index were recorded as 40.54±0.63, 0.077±0.003, 0.502±0.006, 70.213±0.700, 0.323±0.003 and 75.725±0.407 respectively.

    STUDIES ON BODY CONFORMATION, PERFORMANCE AND EXPRESSION OF CERTAIN GENES RELATED TO PROLIFICACY IN SIROHI GOATS UNDER FARM CONDITION IN ASSAM
    (Assam Agricultural University, Khanapara,Guwahati, 2017-07) SARMAH, SANGEETA; Das, Arpana
    The present study was conducted for performance evaluation of certain traits of growth and reproduction in Sirohi goats as well as to study the expression profile of GDF 9 gene related to prolificacy in Sirohi and Assam Hill goats. Data on 250 Sirohi goats for the study of growth and morphometric traits and 310 Sirohi goats for the study of reproductive traits maintained at the Sheep and Goat Breeding Farm, Silonijan, Karbi Anglong , Assam were utilized for the study. The least square means for body weight, body length, heart girth and height at wither were 2.500±0.012 kg, 25.060±0.135 cm, 25.988±0.172 cm and 25.846±0.181cm at birth; 5.607±0.041kg, 41.442±0.232 cm, 45.378±0.391cm, 41.750±0.248 cm at 3 month; 11.734±0.107 kg, 50.527±0.220 cm, 55.390±0.368 cm and 51.915±0.290 cm at 6 month; 16.778±0.177 kg, 60.864±0.212 cm, 62.978±0.323 cm and 62.173±0.272 cm in 9 month; 22.864±0.196 kg, 71.107±0.217 cm, 71.613±0.227 cm and 71.851±0.239 cm at 12 month of age respectively. Parity and period of birth exerted significant (P<0.01) effect on body length, heart girth and height at wither 12 month of age. Season of birth had significant effect (P<0.01) on body weight, body length, heart girth and height at wither. Body weight, body length and heart girth also differed significantly (P<0.01) due to kidding type and single born kids had higher values than the twins. Significant effect of sex was observed on body weight, body length, heart girth and height at wither at all age groups. The male goats were superior to the females in respect of all these traits. The least square means for age at first kidding, gestation period, service period and interkidding period pertaining to first parity were 701.710±2.267 days, 148.895±0.321 days, 195.545 ±1.513 days and 343.898±1.584 days, respectively. The overall mean for gestation period, service period and interkidding period pertaining to all parities were 147.800±0.429 days, 188.553±1.201 days and 336.662±1.102 days, respectively. Period of kidding exerted significant effect on age at first kidding, service period and interkidding period. Kidding order also exerted significant effect on service period and interkidding period and lowest values were obtained in 5th parity. The growth pattern of Sirohi goats from birth to one year of age was found to be little slower from birth to 3 month, faster from 3 to 6 month, again slower from 6 to 9 month and then accelerated from 9 to 12 month of age. Linear and multiple regression equations were developed for prediction of 1 year body weight from the body weight at birth, 3, 6 and 9 month of age and observed that prediction of 1 year body weight could be done from the body weight at earlier ages. The phenotypic correlations among the body weight at different ages were found to be high and positive. Expression of GDF9 gene in Sirohi and Assam Hill goat did not differ significantly as revealed by paired t-test.

    A total of 404 animals for body measurement, 810 lactation records for performance traits, 71 birth weight records and 140 milk samples for estimation of milk constituents from indigenous cattle of Arunachal Pradesh were utilized in the present study. The data obtained were classified according to location, age group, lactation order, sex and stage of lactation. The least-squares means for head length, eye to eye space, breadth of forehead, neck length, neck circumference, horn length, horn circumference at base, horn circumference at middle, horn circumference at tip, distance between two horns at base, distance between two horns at middle, distance between two horns at tip, ear length, body length, height at withers, heart girth, pouch girth, length of arm, elbow length, fore shank length, thigh length, hind shank length, length of pes, length of tail, length of switch, length of udder, width of udder, depth of udder, teat length and teat diameter were 32.269 ± 0.112, 12.749 ± 0.048, 13.239 ± 0.040, 27.718 ± 0.085, 56.551 ± 0.237, 10.348 ± 0.087, 10.517 ± 0.035, 7.898 ± 0.037, 3.715 ± 0.020, 12.615 ± 0.038, 16.854 ± 0.044, 17.419 ± 0.046, 16.975 ± 0.032, 98.475 ± 0.155, 97.123 ± 0.153, 117.582 ± 0.241, 122.462 ± 0.243, 24.448 ± 0.048, 25.599 ± 0.043, 24.970 ± 0.041, 26.426 ± 0.052, 27.598 ± 0.054, 29.206 ± 0.061, 50.498 ± 0.160, 26.628 ± 0.072, 30.940 ± 0.105, 21.506 ± 0.069, 9.923 ± 0.037, 4.459 ± 0.024 and 2.762 ± 0.025cm respectively. Age, sex and location had significant effect on various measurements under head and neck, body, legs, feet and tail and udder. The most predominant horn orientation was curved upward (37.30 per cent) with black (55.14 per cent) and grey (44.86 per cent) horn colours and horizontal type of ear orientation. Among the 8 (eight) types of coat colours recorded, brown (30.69 per cent) was predominant, while common colours of muzzle, hoof and switch were black with a frequency of 73.76 per cent, 73.02 per cent and 65.59 per cent respectively. The least-squares means for age at first calving, lactation milk yield, lactation length, peak yield, days to attain peak yield, dry period, gestation period, inter calving period and birth weight of indigenous cattle of Arunachal Pradesh were found to be 44.553 ± 0.138 months, 296.710 ± 0.803 kg, 239.513 ± 0.483 days, 1.820 ± 0.005 kg, 35.974 ± 0.076 days, 209.957 ± 0.742 days, 272.557 ± 0.073 days, 447.085 ± 0.702 days and 14.554 ± 0.103 kg respectively. Location had significant effect on all the productive and reproductive traits except peak yield, days to attain peak yield, dry period and gestation period whereas the effect of lactation order was non-significant for gestation period. Farmers followed semi-intensive type of management system. The least-squares means for fat, solids-not-fat, protein and total solids per cent of milk in indigenous cows of Arunachal Pradesh were 5.895 ± 0.032 per cent, 8.582 ± 0.027 per cent, 2.790 ± 0.017 per cent and 14.483 ± 0.048 per cent respectively. Location and lactation order showed non-significant effect on all the milk constituents viz., fat, solids-not-fat, protein and total solids percentage however, stage of lactation showed significant effect on fat and total solids percentage.
