Govind Ballabh Pant University of Agriculture and Technology, Pantnagar

After independence, development of the rural sector was considered the primary concern of the Government of India. In 1949, with the appointment of the Radhakrishnan University Education Commission, imparting of agricultural education through the setting up of rural universities became the focal point. Later, in 1954 an Indo-American team led by Dr. K.R. Damle, the Vice-President of ICAR, was constituted that arrived at the idea of establishing a Rural University on the land-grant pattern of USA. As a consequence a contract between the Government of India, the Technical Cooperation Mission and some land-grant universities of USA, was signed to promote agricultural education in the country. The US universities included the universities of Tennessee, the Ohio State University, the Kansas State University, The University of Illinois, the Pennsylvania State University and the University of Missouri. The task of assisting Uttar Pradesh in establishing an agricultural university was assigned to the University of Illinois which signed a contract in 1959 to establish an agricultural University in the State. Dean, H.W. Hannah, of the University of Illinois prepared a blueprint for a Rural University to be set up at the Tarai State Farm in the district Nainital, UP. In the initial stage the University of Illinois also offered the services of its scientists and teachers. Thus, in 1960, the first agricultural university of India, UP Agricultural University, came into being by an Act of legislation, UP Act XI-V of 1958. The Act was later amended under UP Universities Re-enactment and Amendment Act 1972 and the University was rechristened as Govind Ballabh Pant University of Agriculture and Technology keeping in view the contributions of Pt. Govind Ballabh Pant, the then Chief Minister of UP. The University was dedicated to the Nation by the first Prime Minister of India Pt Jawaharlal Nehru on 17 November 1960. The G.B. Pant University is a symbol of successful partnership between India and the United States. The establishment of this university brought about a revolution in agricultural education, research and extension. It paved the way for setting up of 31 other agricultural universities in the country.

    Studies on immune status of indigenous and exotic breeds of domestic fowl
    (G.B. Pant University of Agriculture and Technology, Pantnagar - 263145 (Uttarakhand), 2019-08) Yadav, Renuka; Rajesh Kumar
    Present study was carried out for comparative evaluation of some indigenous and exotic breeds of domestic chicken with regard to the innate immune response, adaptive immune response and resistence to infection following challenge with infectious agent. One exotic (RIR) and two indigenous breeds (Kadaknath, Uttara fowl) were used for study. All the birds were reared in deep litter system with ad-libtum feed and water throughout the experiment. The experiment lasted for 60 days. Significant difference was observed among parameters studied viz; mean total leukocyte count, differential leukocyte count, leukocrit, serum globulin, A/G ratio, phagocytic activity and opsonocytophagic index, among various breeds of chicken at all stages and all the innate and adaptive immune parameter was significantly higher in RIR compared to Kadaknath and Uttara fowl breed of chicken. The RIR showed highest hemagglutination inhibition titre following NDV immunization till the end of the experimental period followed by Kadaknath and Uttara fowl. Cell mediated immune (CMI) response was also observed to be higher for RIR breed compared to Kadaknath and Uttara fowl. The lymphocyte stimulation index was highest in RIR and the lowest in Uttara fowl. Maximum mortality was observed in Uttara fowl up to 15 days post challenge with a virulent virus and antibody titre was maximum in RIR breed at 3 and 7 days post challenge but at 14 days post challenge kadaknath showed highest antibody titre.

    Studies on epidemiology, isolation and molecular analysis of fowl adenoviruses from the domestic chicken with respiratory disease conditions
    (G.B. Pant University of Agriculture and Technology, Pantnagar - 263145 (Uttarakhand), 2019-08) Bisht, Ritika; Rajesh Kumar
    Fowl adenoviruses (FAdV) are the ubiquitous and cause extensive damage to the poultry industry. They are known to be associated with various disease conditions such as Inclusion body hepatitis, Hydropericardium Syndrome, respiratory disease, tenosynovitis, impaired growth, reduced egg production, aplastic anemia, atrophy of bursa and thymus, enteritis and conjunctivitis in chickens and other birds. Present study was undertaken to study epidemiology, to isolate and perform molecular analysis of fowl adenoviruses from the chickens with the respiratory disease conditions. Natural outbreaks investigated during the study revealed 2 –15% mortality among the affected birds aged 3-6 weeks. General postmortem findings were enlarged and friable liver with necrotic foci, enlargement of kidney, congestion and haemorrhagic trachea, congested lungs. Four isolates of fowl adenoviruses were propagated in primary CEL cell culture. The cytopathic effects were characterized by rounding of the cells, degeneration, increase in the refractive index of the cells and microplaques formation. AGPT, CIEP, IFAT, Dot-ELISA and Sandwich ELISA determined the presence of the virus in infected tissues and cell culture. Intensely basophilic intra nuclear inclusion bodies were also visualized following MGG staining of CEL cells. The genomic DNAs were extracted from the infected CEL cells and PCR was carried out for amplification of L1 region of the hexon gene showing amplicons of the ~900 bp. On digestion with MluI, three isolates were digested and the two bands of 400 and 500 bp were visualized and with the enzyme StyI, only one isolate was digested and two bands of 480 and 420 bp were obtained. None of the isolates were digested by the enzymes BglI, BsiWiI and ScaI. RE analysis revealed that isolates belong to two serotypes 5 (R-66) and 8 (R-53, R-43, R-63). Thus, it can be concluded that these serotypes are involved in respiratory disease of domestic chickens in India.
