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.

    Separation of X and Y sperms in bovine semen and their detection following enrichment

    The present study was conducted to observe the effect of percoll density gradient method on X-sperm enrichment and quality of semen. It was performed at Semen Production Centre, CVASc, GBPUAT, Pantnagar, Uttarakhand. Ejaculates were collected by AV method from Crossbred and Sahiwal bulls. Xsperm enrichment was done by percoll density gradient method. Three types of gradients were prepared i.e. 7 layers (70-10%), 7 layers (80-20%) and 3 layers (30%, 505 and 70%). Semen (1ml or 3ml) was placed over the gradient in conical centrifuge tube. Centrifugation was done at 750 xg (22-24°C) for 15 min. Thus, Raman spectroscopy was performed in different groups. Those were fresh semen (Control), 7 layers (70%) (G III), 7 layer (80%) (G IV) and 3 layer (70%) (G V). The pellets obtained were diluted in PBS or EYC medium. Raman peaks (DNA specific) were not much clear for PBS diluted though intensities were highest for 7 layer (70%). Thus, quantification of X-sperms in enriched EYC diluted semen was done by calculating and comparing area at 785, 1095 and 1581 cm-1. There was 26-30% and nearly 17-20% X-sperm enrichment in 7 layer (70%) percoll centrifugation compared to control in Crossbred and Sahiwal, respectively. pH of percoll density gradient centrifuged (supernatant) decreased significantly (P<0.05) in Crossbred semen. Progressive motility of percoll density gradient centrifuged (supernatant) decreased significantly (P<0.05) in Crossbred semen. Live spermatozoa (%) of enriched semen (pellet) were increased in Crossbred and Sahiwal semen. Acrosome integrity was not affected in all the groups in Crossbred bull whereas intact sperm decreased significantly (P<0.05) in percoll density gradient centrifuged supernatant of Sahiwal semen. HOST responsive sperms were not affected in all the groups of Crossbrd and Sahiwal semen. X-sperms enrichment of 29.9% and 20.48% in Crossbred and Sahiwal semen was achieved by percoll density gradient method (7layer 70%). Semen quality of enriched semen was also not affected. Thus semen enriched by percoll density gradient method (7 layer 70%) can be used to increase female calves birth after A.I.
