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.

    Gross, histological and ultrastructural studies on male reproductive system of guinea fowl (Numida meleagris)
    (G.B. Pant University of Agriculture and Technology, Pantnagar - 263145 (Uttarakhand), 2018-07) Tamilselvan, S.; Singh, Balwinder
    This work was carried out on male reproductive system of 54 apparently healthy male guinea fowl (Pearl variety) at different age groups from Day old, 2, 4, 8, 12, 16, 20, 24 and 28 weeks at monthly intervals. The testes were paired organs, located within the abdominal cavity attached to the dorsal body wall by mesorchium. They were small rice sized upto 8 weeks of age followed by elongated bean shaped, white to creamy white in colour from 12 to 28 weeks of age. The epididymis was spindle shaped with white to creamy white in colour. It was clearly visible and detachable from 12 weeks of age. The ductus deferens was paired extended from caudal end of epididymis to opening of urodeum. The convulations first appeared from 20 weeks from caudal to cranial end. The testes were covered by capsule which consisted of outer thin mesothelium and inner thick tunica albuginea. No lobules and no mediastinum were observed. Testicular parenchyma consisted of interstitial tissues and seminiferous tubules which was surrounded by thin sheet of peritubular boundary tissues. The seminiferous tubules were lined by spermatogonia, primary spermatocytes, secondary spermatocytes and spermatids in a stratified manner. At 8 weeks of age, largest primary spermatocyte was observed. In later age groups, leptotene, zygotene and pachytene spermatocytes were seen which produce secondary spermatocytes by first meiotic division. At 16 weeks of age, secondary spermatocytes also appeared in the seminiferous tubules. By 20 weeks of age, fully formed spermatozoa were observed in lumen of seminiferous tubules. Sertoli cell nuclei of varying shapes were located at basal lamina and towards lumen. The Leydig cells were polyhedral cells with large central spherical nuclei was located in interstitial region. The rete testis was lined internally by simple squamous which abruptly changed to pseudostratified columnar epithelium in proximal efferent ductules. The mucosal folds in efferent ductules were of leaf to tongue shaped. Connecting ductules and ductus epididymis were lined by pseudostratified epithelium and its lumen densely packed with spermatozoa. The histochemical and histoenzymic studies revealed that in all age groups, moderate to strong PAS positive reaction was observed in the tunica albuginea, basement membrane and germ cells of testis, apical borders of the efferent ductules, connecting ductules, ductus epididymis and ductus deferens. Moderate lipid activity was observed in basement memebrane of testis, luminal border of lining epithelium of efferent ductules, connecting ductules, ductus epididymis and ductus deferens. Weak to mild reaction for acid phosphatase and cholinesterase in seminiferous tubule was observed. Moderate to strong reaction for cholinesterase and alkaline phosphatase was observed in capsule, basement membrane of testis and apical border of efferent ductules, connecting ductules and ductus epididymis. Strong dehydrogenase activity was observed in throughout the testis, luminal border of all the ductules of epididymis and ductus deferens. Under scanning electron microscopy, the testes covered by thick capsule and parenchyma contained interstitial tissue and highly coiled seminferous tubules. The tubules lined by germ cells and sertoli cells in stratified manner towards lumen, where the spermatozoa were extended its tails towards center. The epididymis covered by thick capsule, which contained extratesticular part of rete testis, irregular shaped efferent ductules which were lined by smooth epithelium. The connecting ductules and ductus epididymis were almost similar which lumen fully packed with spermatozoa. The ductus deferens was tubular organ, which lined by smooth uniform epithelial layer and thick fibromuscular layer. Its luminal surface had few longitudinal mucosal folds with depressions and the lumen tightly packed with spermatozoa.
