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.

    Genetic studies on prediction of lactation yield based on test day values in Sahiwal and crossbred cattle
    (G.B. Pant University of Agriculture and Technology, Pantnagar - 263145 (Uttarakhand), 2017-06) Girimal, Dhanraj Gurubasappa; Kumar, D.
    The present investigation was carried out for studying the different fortnightly test day milk yield traits, first lactation milk yield traits, prediction of first lactation yield on the basis of single test day milk yield and stepwise backward elimination method and comparing the different sire evaluation methods. The records of 799 daughters of 58 sires in crossbred cattle and 166 daughters of 19 sires in Sahiwal cattle maintained at Instructional Dairy Farm, G.B.P.U.A& T, Pantnagar were utilized for this study. The least squares means along with standard errors of AFC, FL305DMY, FLL, FLPY and fortnightly test day milk yield (FTDY-1 to FTDY-21) traits were observed as 1445.34±30.77 days, 1716.04±78.47 kg, 248.45±9.84 days, 8.84±0.15 kg and 4.29±0.5, 5.34±0.7, 7.71±0.6, 7.63±0.8, 7.45 ±0.10, 7.11±0.90, 7.08±0.10, 6.87±0.75, 6.34±0.08, 6.34±0.08, 6.12±0.64, 6.34±0.12, 5.96±0.54, 5.65±0.12, 5.28±0.10, 4.74±0.10, 4.24±0.11, 3.49±0.84, 3.28±0.07, 2.93±0.47, 2.73±0.03 and 2.50±0.03 kg respectively, in Sahiwal cattle. The corresponding figures for crossbred cattle were observed as 1376.15±24.19 days, 2657.69±63.18 kg, 283.93±4.94 days and 13.18 kg. 4.48± 0.13, 5.6±0.2, 9.53±0.48, 9.35±0.6, 8.7±0.45, 8.6±0.6, 8.35±0.08, 7.83±0.3, 7.6±0.7, 7.11±0.08, 6.56±0.45, 6.08±0.32, 5.71±0.8, 5.27±0.21, 5.26±0.18, 4.98±0.78, 5.13±0.21, 4.51±0.74, 5.03±0.11, 4.75±0.02 and 4.49±0.81 kg respectively. The heritability estimates of AFC, FL305DMY, FLL and FLPY traits in case of Sahiwal and crossbred cattle indicated that some improvement can be made in these traits by selecting the cows for these traits up to some extent. However, the major improvement in these traits can be done by good managemental practices at the farm. The heritability estimates for early test day milk records were lower in magnitude and later in the middle of lactation, the values were found to be comparatively higher in magnitude. All the genetic and phenotypic correlations between FL305DMY and different test day milk yield found to be positive in direction. The genetic and phenotypic correlations among test day milk yield revealed that the data on test day milk yields can be utilized for extending the incomplete records and also utilized under various selection programmes. The step wise regression was best fitted for predicting the FL305DMY followed by regression and ratio method. The fitting of step wise multiple regressions, the higher estimates of accuracy of prediction for FL305DMY were found in the middle part of the lactation (FTDY8 to FTDY-10 in Sahiwal and FTDY-7 to FTDY-11 in crossbred cattle). The multiple regression equations with six variables viz. peak yield, FTDY-2, FTDY-6, FTDY-8, FTDY-10 and FTDY-15 in case of crossbred cattle and peak yield, FTDY-2, FTDY-3, FTDY-6, FTDY-10, and FTDY-11 in case of Sahiwal were considered more appropriate for prediction of first lactation 305 day milk yield with high accuracy. The BLUP method was found to be superior for selecting the sires for first lactation milk yield followed by LSM and Simple daughter average method.
