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.

    Genetic studies on first lactation traits and sire evaluation using different methods in murrah buffaloes
    (G.B. Pant University of Agriculture and Technology, Pantnagar - 263145 (Uttarakhand), 2007-04) Tiwari, Reetu; Kumar, D.
    The present investigation was undertaken utilizing the records of 577 daughter-dam pairs of Murrah buffaloes maintained, maintained at 8 military dairy farms Ferozepur, Ambala, Jullundhar, Jhansi, Lucknow, Merrut, Bareilly and Agra) and one instructional dairy farm of G.B. Pant. Univ. of Agri. & Tech., Pantnagar for studying the inheritance pattern of different economic traits and to evaluate the sires using Least-squares (LS), Best linear unbiased prediction (BLUP) and Derivative free restricted maximum likelihood (DFREML) methods. Least squares means of age at first calving (AFC), first calving interval (FCI), first lactation milk yield (FLMY), first lactation period (FLP), weight at first calving (WFC) and first service period (FSP) of daughters were 43.38 ± 0.94 months, 418.14 ± 17.16 days, 1903.37 ± 60.67 kg, 326.43 ± 7.89 days, 509.93 ± 6.93 kg and 134.99 ± 17.11 days, respectively. The heritability estimates of AFC, FCI, FLMY, FLP, WFC and FSP traits were estimated as 0.40 ± 0.15, 0.14 ± 0.10, 0.31 ± 0.14, 0.23 ± 0.12, 0.36 ± 0.13 and 0.06 ± 0.09, respectively. The genetic and phenotypic correlations indicated that selection for lower age at first calving and higher lactation milk yield can be used as a selection criterion for the genetic improvement in the herd. The buffaloes having higher weight at first calving had longer first calving interval, lactated for longer period and conceive earlier. A total number of sixty eight Murrah buffalo sires were genetically evaluated on the basis of 300-day milk yield records of 577 dams and daughter records using six different indices, viz., simple daughter’s average index (I1), equiparent index (I2), corrected daughter average index (I3), contemporary daughter average index (I4), corrected contemporary daughter average index (I5), and dairy search index (I6). The various indices according to the least variances and least standard errors of the index values were ranked as I4, I5, I3, I2, I1 and I6 in relative descending order of superiority. The rank correlation between I1 and I4 was maximum as 0.986, thereby indicated that the index I1 and the index I4 gave the ranking of the sires in more or less in the same order. The rank correlations between I4 and the rest of the indices were found to be comparatively quite low, indicating comparatively more independency of the index I5. The rank correlations among indices I1, I2, I3 and I4 were of highly significant. The rank correlation between I5 and I6 was also highly significant. The sires were also evaluated using LS, BLUP and DFREML methods. LS and BLUP method gave the same result for evaluating the different sires considering all the traits, viz. AFC, FCI, FLMY, FLP, WFC and FSP. The values of lower error variance and high relative efficiency suggested that BLUP method was best for evaluating the different sires followed by LS and DFREML methods using different first lactation traits. The comparison among I4, I5, LS, BLUP and DFREML methods showed that the ranking of sires was different for these methods. The standard errors revealed that LS and BLUP methods were best for evaluating the sires for first lactation milk yield followed by DFREML, I4 and I5 methods.
