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 performance traits and comparison of different lactation curve models in crossbred cattle
    (G.B. Pant University of Agriculture and Technology, Pantnagar - 263145 (Uttarakhand), 2019-03) Arya, Vineeta; Shahi, B.N.
    The present investigation was undertaken utilizing the records of 700 daughter progeny of 68 sires, distributed over a period of 28 years from 1990 to 2017 in crossbred cattle maintained at Instructional Dairy Farm of G.B. Pant University of Agriculture and Technology, Pantnagar to study the effect of different genetic and non- genetic factors, inheritance pattern of different economic traits, to evaluate the sires using BLUP method and to compare the efficacy of different lactation curve models utitizing fortnightly and monthly test day milk yield. The Least squares means (LSM) along with their standard errors of age at first calving (AFC), first lactation milk yield (FLMY), first lactation period (FLP), first dry period (FDP), first calving interval (FCI), first service period (FSP) and first lactation 305 day milk yield (FL305DMY) were estimated as 1186.45±8.66, 2846.16±46.92, 326 51±3.09, 124.29±3.67, 450.80±4.5, 261.34±1.77 and 2631.07±35.68, respectively. LSM of different first lactation fortnightly and monthly milk yield ranged between 83.62±3.69 (FLFMY-20) to 156.05±2.56 (FLFMY-4) and 179.09±6.88 (FLMMY-10) to 307.81±5.02 (FLMMY-2), respectively. The sire effects was significant on AFC, FLMY, FCI, FL305DMY and on almost all fortnightly and monthly milk yields. In contrast, different genetic groups were found to have non-significant effect on all the traits. The effect due to season of calving was observed to be significant on AFC, FLMY, FDP, FSP, FL305DMY and almost all FLFMYs and FLMMYs. The effect due to period of calving were found to have significant influence on FL305DMY and FLMY. The heritability estimates for AFC, FLMY, FLP, FDP, FCI, FSP and FL305DMY were observed as 0.429±0.127, 0.26± 0.110, 0.078 ± 0.087, 0.048 ±0 .083, 0.096 ±0.089, 0.114 ± 0.091 and 0.273±0.110, respectively. The range of heritability for first lactation fortnightly milk yield (FLFMY) was found between 0.157± 0.097 and 0.452± 0.129. While the heritability estimates for first lactation monthly milk yield (FLMMY) ranged between 0.187±0.100 and 0.486±.132. The genetic correlations indicated that selection for lower age at first calving and higher first lactation milk yield can be used as a selection criterion for the genetic improvement in the herd. All the genetic and phenotypic correlations between FL305DMYs with different part lactation milk yields were found positive in direction. The estimation of breeding values of different sires and ranking them on the basis of estimated breeding values by BLUP method may be done in selection and utilization of best sire for improvement programme. The relative efficiency of four lactation curve models viz. Exponential function, Parabolic Exponential function, Inverse Polynomial function and Gamma Type function were compared. Inverse Polynomial Function described the highest coefficient of determination on both fortnightly and monthly milk yiels (R2 = 99.97%) and with least value of root mean squares error (RMSE) and absolute mean deviation (AMD) suggesting Inverse Polynomial function to be the best fitted for explaining the first lactation curve by utilizing the records of fortnightly and monthly test day milk yields.
