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.

    Effect of supplemental chromium picolinate on rumen metabolism, nutrient utilization, milk yield and its quality in crossbred cattle
    (G.B. Pant University of Agriculture and Technology, Pantnagar - 263145 (Uttarakhand), 2008-10) Rikhari, Kusum; Tiwari, D.P.
    Two experiments were conducted to know the effects of chromium supplementation on nutrient utilization, rumen metabolism, milk yield, milk composition and quality and on certain blood biochemical constituents in crossbred cattle. In experiment l three fistulated adult male crossbred cattle assigned randomly to one of three treatments: Treatment 1, Control (without chromium supplementation), Treatment 2, 0.5 mg chromium per kg diet dry matter as chromium picolinate and Treatment 3, 1.0 mg chromium per kg diet dry matter as chromium picolinate in 3x3 latin square switch-over design for three periods. In experiment II, 16 crossbred lactating cows divided in 4 groups of 4 each were assigned to one of four treatments: Treatment 1, Control (without chromium supplementation), Treatment 2, 0.5 mg chromium per kg diet dry matter as chromium picolinate, Treatment 3, 1.0 mg chromium per kg diet dry matter as chromium picolinate and Treatment 4, 1.5 mg chromium per kg diet dry matter as chromium picolinate. Feeding trial lasted for 90 days. There was no significant effect on dry matter intake and digestibility of different nutrients due to supplementation of chromium in experiment I, whereas in experiment II there was significant (P<0.05) difference in dry matter intake per 100 kg body weight and also per kg metabolic body size among the treatments with higher intake in lactating crossbred cows of T4 (1.5 mg Cr/kg dry matter) than the other treatment groups. The mean concentration of total N was significantly (P<0.05) higher in T2 than T3, while TCA-ppt protein N, NPN and Ammonia-N and TVFA concentration did not differ significantly among the treatments but significantly varied between hours of sampling. The ruminal enzyme activities viz., carboxymethyl cellulase, α-amylase, xylanase, and α-glucosidase in rumen content also varied non-significantly with different levels of chromium supplementation, while β-glucosidase activity was significantly (P<0.05) higher in T1 than T2 in particulate material at 2h post-feeding and also significantly (P<0.05) higher in T1 and T2 than T3 in cellular material. Activity of all enzymes was higher in particulate material (PM fraction as compared to cellular fraction (C) and extra cellular fraction (EC). Cr supplementation tended to improvement in milk yield and milk composition. Furthermore, Cr supplementation tended to increase total unsaturated fatty acid concentration in all the chromium supplemented groups and significantly (P<0.01) higher in T2 (0.5 mg Cr/kg DM) supplemented groups than control. Glucose concentration, SGPT and SGOT activities were significantly (P<0.05) higher in all the chromium supplemented groups of cows. It is concluded from the results of the present study that dietary supplementation of chromium had no significant effect on rumen metabolism, however in lactating crossbred cows caused linear improvement in milk yield, milk composition as well as the milk quality.

    Study on the efficacy of Satavari and Ashwagandha root powder supplementation on production, reproduction and carcass traits of Japanese quails
    (G.B. Pant University of Agriculture and Technology, Pantnagar - 263145 (Uttarakhand), 2009-01) Bhardwaj, Rohatash Kumar; Singh, S.K.
    A study was conducted to evaluate the effects of Withania somnifera and Asparagus racemosus root powder extracts on growth performance and haemato-biochemical parameters of Japanese quails. The investigation was carried out on Japanese quails maintained at Instructional Poultry Farm, Pantnagar. All the managemental conditions were kept constant for the whole flock during the experimental period. The herbal extracts at different doses (@ 0.5, 1.0 and 1.5 per cent for both herbs) were administered in feed. Weekly body weight of the birds was recorded from day-old stage to 6 weeks of age. Blood was collected on 42nd day for estimation of haemato–biochemical parameters from the birds supplemented with Withania somnifera and Asparagus racemosus extracts. Inclusion of Withania somnifera and Asparagus racemosus extracts stimulated the growth of the quails. Further, body weight and conformation traits viz shank, keel length and breast angle at 6th week was found to be significantly (P<0.05) higher in group which received @ 1.5 % than the other groups. The weekly feed intake (g) decreased (i.e. lowest FCR) on feeding of Withania somnifera and Asparagus racemosus in quails. This indicated better feed utilization in root extract fed group than control group. Control group birds consumed more quantity of feed in comparison to other treated groups. It was found that during 1st week, only one bird died and subsequently no more death was observed. This could be attributed to good management and developed immune system due to Withania somnifera and Asparagus racemosus extract feeding. On supplementing root extracts of Withania somnifera and Asparagus racemosus, best FCR, PI and BWG was found in root extract (@ 1.5 % fed and lowest in control at 6th week. Further, the best ASM, hatchability, fertility and egg weight was observed in treated groups in comparison to control. Among the treatments, group fed with root extract (@ 1.5% showed maximum edible weight which indicated good feed utilization. However, survivability was lower (96%) than the treated groups. The maximum haemoglobin was recorded in group which received root extract @ 1.5% and minimum in control group, which were found to differ significantly (P<0.05). The PCV, TEC and TLC values of root extract fed group differed significantly (P<0.05) with control group. Feeding of Withania somnifera and Asparagus racemosus extracts showed a positive influence on TSP, albumin, AST, ALT and Immunoglobulin concentrations. It can be concluded that skin thickness and skin diameter was significantly higher in treated groups over the untreated, thus increasing the resistance against effect on a number of extraneous factor from physical, chemical and biological origin. Therefore, root extracts of both medicinal herbs is equally recommendable for poultry feeding, which will ultimately yield more economic profits and further can be exploited for organic food safety.

    Analysis of economic traits and expression profile of different growth related genes in IGF-1 SNP genotypes of Indian colored broilers
    (G.B. Pant University of Agriculture and Technology, Pantnagar - 263145 (Uttarakhand), 2009-06) Pandey, Nitin Kumar; Sharma, R.K.
    IGFs are involved in metabolism and body growth by regulating the synthesis and degradation of glycogen and proteins in animals. In chicken IGF-1 gene, an A570C substitution has been reported to invariably associate with growth, body composition, skeletal integrity, hormonal and metabolic factors. The present study aimed to detect polymorphism in the respective region (promoter and 5’ UTR) in CSML individuals in two generations using Hinf I PCR-RFLP. An array of economic traits viz. Juvenile body weights, Body conformation traits, Carcass traits and crude protein% in breast muscle were recorded on birds of different genotypes of IGF-1. Expression analysis of various growth related genes i.e. IGF-1, IGF-2, IGF-1 receptor, Growth hormone receptor, IGFBP-2, Ghrelin, Myostatin and TGF-β2 were also carried out using real time PCR in liver and breast muscle samples of birds of each of IGF-1 genotype at 45 days of age. Genomic DNA has been isolated from blood using phenol choloroform extraction method. A total of 100 and 96 birds were screened for estimating gene and genotypic frequencies in two successive generations. PCR amplified fragment of 813bp was digested with Hinf I. The Hinf I digestion revealed patterns viz. AA (378, 244 and 191bp), BB (622 and 191bp) and AB (622, 378, 244 and 191bp) in both the generations. The overall frequency of AA, AB and BB genotypes were 0.74, 0.23 and 0.03; in generation I these were 0.70, 0.27 and 0.03; and in generation II 0.78, 0.18 and 0.04, respectively. The frequency of allele A and B in generation I was 0.83 and 0.17 and in II generation 0.87 and 0.13, respectively, with an overall frequency of A and B alleles as 0.85 and 0.15, respectively. Significant differences among IGF-1 genotypes were observed on body weights at III, IV and V weeks of age in first generation and on body weight at V and VI weeks of age in II generation. IGF-1 AA and IGF-1 AB genotype exhibited higher body weights than IGF-1 BB genotype birds. Significant effect of IGF-1 genotypes on conformation traits was observed in both the generations. IGF-1 AA and IGF-AB genotypes had significant effect on all the carcass traits except EY%, heart, gizzard, giblet and abdominal fat in first generation and EY%, spleen and bursa in II generation. For cutup parts IGF-1 genotype had significant effect on back, thigh, drumstick and wing in first generation and on all the cut-up parts except back weight in II generation. IGF-1 AA genotype birds exhibited significantly higher CP% in breast muscle as compared to that IGF-1 AB genotype birds. Expression profile of all the genes studied showed pattern of higher expression in hepatic tissue of AB and AA genotypes as compare to BB genotype. However, except myostatin, the picture was reverse in PM muscle, where expression was higher in IGF-1 BB genotype.

    Construction of selection indices and evaluation of various selection procedures in Rhode Island Red
    (G.B. Pant University of Agriculture and Technology, Pantnagar - 263145 (Uttarakhand), 2008-01) Jilani, Mujahid Husain; Singh, Brijesh
    The present study was carried out on 771 pullets of a commercial strain of RIR maintained by commercial poultry breeding organization. These pullets were produced by mating of 196 dams and 50 sires in three different hatches. Data were subjected to analysis of mean values, genetic parameters, construction of selection indices and evaluation of efficiency of various selection procedures for improving overall genetic worth of flock. The averages of ASM, BW18, BW32, EP and EW were found as 146.133±0.543 days, 1393.733±6.940 g, 1670.617±9.200 g, 107.159± 0.195 eggs and 54.326±0.17g, respectively. The corresponding heritability estimates based on sire, dam, sire + dam component of variance and REML methods were as 0.322±0.121, 0.745±0.150, 0.533±0.085 and 0.526±0.078; 0.281±0.114, 0.533±0.144, 0.407±0.079 and 0.413±0.082; 0.329±0.122, 0.670±0.148, 0.500±0.083 and 0.514±0.087; 0.519±0.152, 0.575±0.146, 0.549±0.085 and 0.551±0.084; 0.353±0.126, 0.182±0.130, 0.268±0.070 and 0.317±0.067 for ASM, BW20, EP and EW, respectively. The genetic and phenotypic correlation of ASM×BW40, BW20×BW40, BW20 × EW and BW40 × EW were found to be positive whereas negative correlations were found for ASM × BW20, ASM × EP, BW20xEP, BW40 x EP and EP × EW. Out of twenty-six selection indices constructed by incorporating all the five traits in all possible combinations, IMT1 was found to be best index. Eight restricted selection indices were constructed by imposing 50 and 100 % restriction on ASM and EW, where index RSI2 was found to be best index, which was developed by imposing 50 % restriction on ASM. Out of 28 multi-trait multi-source indices, IMTMS1 incorporating all the five traits and all the three sources of information showed highest ΔH and RIH values. Two-stage selection (Scheme-A) of set-I in which initial selection of 50% pullets done on the basis of ASM and BW20 and final selection of 40% pullets out of first stage selected pullets on the basis of all the five traits was found to be more efficient than one stage selection (IMS1.1). Evaluation of three methods of selection indicated that SI and BLUP methods were consistently superior to SP method for all the traits under consideration. Spearmen rank correlation coefficient of best ranking with ranking obtained from three methods for various economic traits of RIR revealed that the greatest differences among ranking of animals by the three methods were found for EP and smallest differences among ranks were found for EW.
