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.

    Osteosynthesis in induced tibial segmental defect using co-precipitated hydroxyapatite gel and titanium mesh cage in rabbits (Oryctolagus cuniculus)
    (G. B. Pant University of Agriculture and Technology, Pantnagar, 2022-09) Karki, Nikita; Karki, Nikita; Das, Arup Kumar; Das, Arup Kumar
    The present study was conducted in (12) clinically healthy adult New Zealand white rabbits (1.5-2.0 years old), of either sex weighing 1.5-2.0 kg and they were subjected to induction of segmental defect in tibia under general anaesthesia. Thereafter, insertion of intramedullary titanium pin along with cylindrical titanium mesh cage and injectable co-precipitated HA gel used for reconstruction of segmental defect in tibia. All rabbits were divided randomly in two groups (A and B) with 6 animals in each group. In rabbits of Group A fracture fragments were stabilized with titanium mesh and titanium screws. While in rabbits of Group B, fracture fragments were stabilized with titanium mesh cage, reinforced with intramedullary pin and injectable co- precipitated HA ladened Mg-gelatin-collagen gel was used. The common features included in each rabbits of both the groups were anaesthetic regimen – premedication with glycopyrrolate, xylazine and induction of ketamine anaesthesia was pursued. Maintenance of anaesthesia was done with Isoflurane @ 1-1.5 percent concentration of with 100 percent oxygen saturation. On the basis of evaluation of parameters, better wound healing was observed in animals of Group B as compared to animals of Group A. On the basis of biochemical parameters, faster and better wound healing was observed in rabbits of Group B. Estimation of haematological and biochemical parameters were done at day 0, 7, 15, 30 and 60. There was a significant increase in serum values of ALP, calcium, phosphorus, blood glucose and decrease in magnesium, total protein. Radiological findings showed faster rate of healing and earlier reduction in gap (1.00 cm) and moderately higher radio-denser area at induced segmental defect in tibia of animals of Group B. On gross observation of test bones, negligible gap was observed at induced segmental defect in animals of Group B depicting faster healing, mineralization of developed callus and bridging of segmental defect as compared to animals of Group A. There was new bone formation found around the external circumference of the cage which was bridging the proximal and distal bone cage junction. Exuberant callus formation was found around the cage in animals of Group B. The implant remained completely stable, in correct alignment and found in pre-experimental state in animals of Group B. Titanium mesh cage used here act as scaffold for bony restoration, allows vascular supply both to the mucosa and bone during regeneration phase. The construct used here for osteosynthesis of induced segmental defect at tibia provided adequate mechanical strength, augment limb stability and early bone continuity. Conclusively a better fracture healing was observed in rabbits of Group B as compared to rabbits of Group A and it reveals that the co-precipitated HA gel used act as scaffold for bony restoration and hence it possess attributes of biodegradability, biocompatibility. The above mentioned technique can be use for treatment of long bone segmental defect as it has got wide scope to be used in clinical veterinary practice. In the present study the outcome of surgical management of large segmental defects in tibia using cylindrical titanium mesh cage was found to be effective for treatment of LBSD.

    Studies on application of machine learning techniques for prediction of milk yield in crossbred cattle
    (G. B. Pant University of Agriculture and Technology, Pantnagar, 2022-10) Nayla Fraz; Shahi, B. N.
    The present study was undertaken utilizing the records of 567 daughter progeny of 55 sires, distributed over a period of 30 years from 1990 to 2019 in crossbred cattle maintained at Instructional Dairy Farm of G.B Pant University of Agriculture and Technology, Pantnagar (Uttarakhand) to study the inheritance pattern of different economic traits and for the prediction of first lactation 305 days milk yield. The Least squares mean (LSM) along with their standard errors of age at first calving (AFC), first service period (FSP), first dry period (FDP), first lactation length (FLL), first calving interval (FCI), first lactation peak yield (FLPY), days to attend peak yield (DPY), first lactation milk yield (FLMY) and first lactation 305-day milk yield (FL305DMY) were observed as 1268.85 ±16.75 days, 267.51 ± 1.93 days, 91.56 ± 1.86 days, 369.41 ± 6.68 days, 465.80 ± 6.64 days, 13.88 ± 0.17 kg, 39.76 ± 0.78 days, 3294.64 ± 77.93 kg and 2570.74 ± 38.30 kg, respectively.Significant effects of sire were found on AFC, FLPY, DPY, FLMY and FL305DMY. Significant effect of period of calving was observed on AFC, FSP, DPY, FLMY, and FL305DMY while non-significant effect was found on FDP, FLL, and FCI. The effect of season of calving was found non-significant for all the first lactation traits under study. The heritability estimates for the traits under study AFC, FSP, FDP, FLL, FCI, FLPY, DPY, FLMY and FL305DMY were observed as 0.34 ± 0.21, 0.10 ± 0.1, 0.12 ± 0.11, 0.45 ± 0.16, 0.32 ± 0.17, 0.42 ± 0.22, 0.40 ± 0.20, 0.54±0.19 and 0.59±0.20,respectively. The genetic and phenotypic correlations between first lactation traits were found to vary from range low to high. The ranking of sires for estimated breeding values (EBV) was compared for all animals using Pearson's correlations or Spearman's rank order correlations. Spearman's rank correlations between sire estimated breeding valuesranged between 0.05 and 0.78. For prediction of first lactation 305 days milk yield different machine learning models were used viz., multiple linear regression (MLR), random forest (RF), gradient boosting regression (GBR), extreme gradient boosting (xgboost) and light gradient boosting (light GBM) and their comparative evaluation was done on the basis of root mean square errors (RMSE) and coefficient of determination (R2) values suggesting that accuracy and precision of RF, GBR, light GBM and xgboost models were adequate in predicting first lactation 305 days milk yield, but the best results were obtained by RF in both training and testing data, it outperformed other regression models in predicting first lactation 305 days milk yield. Machine learning models can be used in dairy industries for the prediction of milk yield in dairy cattle to increase the efficiency of dairy farms and early culling of animals based on 305 days milk yield.

    (G. B. Pant University of Agriculture and Technology, Pantnagar, 2022-09) Ghalaut, Bharat; Das, Arup Kumar
    The present study was conducted on six male goats. Six full thickness incisional wound of 1 inch length and six excisional wounds of 1 inch × 1 inch dimension were created on both side of the back with an objective to evaluate the healing efficacy of four different topical polyherbal formulations. One positive control was treated with Soframycin ointment from day of wound creation till recovery. The other four test sites were treated with Charmil Plus gel, Charmil Spray, AV/CPS/23 lotion and Brand A respectively. One wound site was left untreated as negative control. The wounds were evaluated on the basis of clinical, macroscopical and haematobiochemical studies. Clinical and haematobiochemical parameters did not reveal any significant change between the different treatments and were variable within normal physiological limits. For clinical evaluation- quantity of exudation, wound contraction and rate of wound healing was observed. The result revealed less exudation with better healing rate and wound contraction in test product Brand A followed by Charmil spray, AV/CPS/23, and Charmil ointment in decreasing order; and all the wounds that got treatment were found to have better healing than the negative control wound

    (G.B. Pant University of Agriculture and Technology, Pantnagar, District Udham Singh Nagar, Uttarakhand. PIN - 263145, 2022-12) Kharvi, Shraddha; Sharma, R.K.
    The present trial was carried out to discern the effect of peppermint and eucalyptus essential oil supplementation on the performance parameters, nutrient utilization, haemato-biochemical and health status related parameters, carcass traits, meat composition and economics of Japanese quails. A total of a total of 180, six days old Japanese quails individually were weighed and randomly divided into five treatments which consisted of three replicates having 12 birds each. The experimental treatment groups were: T0 control (basal diet), T1 (basal diet + 0.2% of peppermint essential oil), T2 (basal diet + 0.2% of eucalyptus essential oil), T3 (basal diet + 0.1% of peppermint essential oil + 0.1% of eucalyptus essential oil) and T4 (basal diet + 0.05% of peppermint essential oil + 0.05% of eucalyptus essential oil). Growth parameters were studied at weekly intervals as well as during different periods viz. Starter (I-II week), Finisher (III-V week) and Overall period (I-V week). A metabolic trial of 7 days duration was conducted after feeding trial i.e., from day 35th – 42nd to determine the impact of peppermint and eucalyptus essential oils supplementation on nutrient utilization. At the end of feeding trial on 35th day, two Japanese quails from each replicate (six Japanese quails/treatment) were randomly selected and slaughtered to study carcass yield, cut up parts yield, organ weights and processing losses. At the same time representative blood and meat samples (thigh and breast) were also collected for study of haemato- biochemical parameters and meat composition. Results of experiment indicated that inclusion of peppermint and eucalyptus essential oils significantly (P<0.05) reduced feed intake, increased body weight gain, improved feed conversion ratio and performance index, with best performance during all the periods was found in T3 group. The nutrient utilization in terms of dry matter, crude protein, ether extract and organic matter were improved with peppermint and eucalyptus essential oils supplementation in Japanese quails with maximum nutrient utilization was observed in T3 group of Japanese quails. The blood profile revealed that TEC, Hb and PCV were improved in all the essential oil supplemented groups of Japanese quails and MCV showed reduction in essential oils supplemented groups. Serum glucose was reduced in peppermint and eucalyptus essential oils supplemented groups except T4, whereas serum total cholesterol levels and serum triglycerides were significantly reduced in Japanese quails of all supplemented groups, except T4 group. Serum LDL cholesterol levels were reduced in Japanese quails of all supplemented groups. Serum HDL-cholesterol was increased in all peppermint and eucalyptus essential oils supplemented groups with maximum value observed in T4 group of Japanese quails. Serum total protein, albumin and globulin were improved in all peppermint and eucalyptus essential oils supplemented groups of Japanese quails. Serum uric acid, serum creatinine, serum bilirubin levels, SGPT and SGOT were significantly reduced by peppermint and eucalyptus essential oils supplementation in Japanese quails. The essential oil improved dressed yield without and with giblets. Cut up parts in terms of thighs, breast and drumsticks and neck weights were significantly (P<0.05) improved in peppermint and eucalyptus essential oils supplemented groups with maximum thigh, neck and breast weight observed in T3, while highest drumstick weight was noted in T2 group of Japanese quails. Peppermint and eucalyptus essential oils improved weight of liver. Processing losses were not affected due to essential oil supplementation. Crude protein and crude fat content in thigh and breast meat was increased in all essential oil supplemented groups except T4. However, moisture and total ash content of thigh and breast muscles were not affected. Combination of peppermint and eucalyptus essential oils supplementation reduced the feed cost per kg weight gain significantly (P<0.05) with minimum feed cost per kg weight gain was noted in Japanese quails of group supplemented with 0.1% peppermint and 0.1% eucalyptus essential oils in combination. From the results of present investigation, it can be concluded that dietary supplementation of peppermint and eucalyptus essential oils in combination at 0.1% and 0.1% concentrations each may be advised to improve growth performance, nutrient utilization, haemato-biochemical and health status related parameters, carcass traits, meat composition and production economics of Japanese quails. Further research may be carried out using these and other essential oils in laying Japanese quails and other species of poultry.

    (G.B. Pant University of Agriculture and Technology, Pantnagar, District Udham Singh Nagar, Uttarakhand. PIN - 263145, 2022-07) Sulekha; Kandpal, Manjul
    Eighteen dogs of either sex, different breed, body weight and age (requiring various surgical corrections) were randomly divided into three groups namely A, B and C. Atropine sulphate (0.025mg/kg SC) was administered in all the groups followed by tiletamine-zolazepam (till effect IV) in group A, xylazine (0.5mg/kg IM) and tiletamine-zolazepam (till effect IV) in group B and xylazine (0.5mg/kg), ketamine (2.5mg/kg) and tiletamine-zolazepam (till effect IV) in group C. The induction dose of tiletamine-zolazepam observed in group A, B and C were 6.5, 5.5 and 4 mg/kg body weight respectively on intravenous administration. The efficacy of the anaesthesia was evaluated by observing clinical (induction dose, induction time, duration of anaesthesia, sternal recumbency time, complete recovery time, jaw relaxation score, pedal reflex score and palpebral reflex score), physiological (heart rate, respiration rate, rectal temperature, capillary refill time, systolic arterial pressure, diastolic arterial pressure, mean arterial pressure and haemoglobin oxygen saturation), haematological (haemoglobin, total erythrocyte count, packed cell volume, total leucocyte count and differential leucocyte count) and biochemical (total protein, plasma glucose, blood urea nitrogen, serum creatinine, total bilirubin, alanine aminotransferase and aspartate aminotransferase) parameters before and after administration of anaesthetic drugs. Anaesthetic effects like analgesia and muscle relaxation was observed to be slightly better in group C in comparison to group A and B. Heart rate increased and respiration rate decreased post induction in all three groups. Haematological parameters like haemoglobin, total erythrocyte count, packed cell volume, total leucocyte count, lymphocytes, monocytes, eosinophils and basophils showed transient decrease whereas neutrophils showed transient increase in all the groups at 30 and 60 minutes post induction and approximately approached baseline value by 24 hours. Biochemical parameter like total protein showed transitory decrease whereas plasma glucose, blood urea nitrogen, serum creatinine, total bilirubin, alanine aminotransferase and aspartate aminotransferase reported an increase in all the groups at 30 and 60 minutes post induction and approached baseline values by 24 hours. These changes in haematological and biochemical parameters were within normal physiologic range. Tiletaminezolazepam with its fast and smooth induction, intermediate duration of action, excellent muscle relaxation and good compatibility with xylazine and ketamine, was found to be an effective general anaesthetic either alone or in combination. Group C with xylazine, ketamine and tiletamine-zolazepam combination required significantly lower induction dose and provided longer duration of anaesthesia in comparison to group A and group B.

    Studies on echostructural pattern of urinary system in adult female goats
    (G.B. Pant University of Agriculture and Technology, Pantnagar, District Udham Singh Nagar, Uttarakhand. PIN - 263145, 2022-07) Singh, Shivani; Das, Arup Kumar
    B-mode ultrasonographic study of urinary system was performed in 20 healthy adult female Jamunapari goats. Mean±S.E. values of body weight and age of selected animals were 27.49±0.79kg and 2.77+0.10 years, respectively. All twenty animals were subjected to sonographic examination after clipping the hairs from desired sites to scan the various organs of urinary system in standing position under physical restraint without using any anesthetic agent. The values of various clinico-physiological parameters including rectal temperature, heart rate, respiration rate, colour of mucous membranes were recorded to examine the health status prior to sonography. The left and right kidneys were scanned from right dorsal flank by paravertebral approach using a transcutaneous micro-convex probe at 5 MHz and a convex probe at 2.8-6 MHz frequency. A dual frequency (5-9 MHz) micro-curved array cavity probe was used to scan bladder and urethra per rectally. The renal parenchyma in healthy goats was distinctly divided into hypoechoic outer cortex and anechoic inner medulla. The hyperechoic renal sinus complex (fat, vessels, lymphatics and fibrous tissue) was present in centre of the kidney and renal pelvis was anechoic. The renal capsule was seen as hyperechoic fine line surrounding the renal parenchyma. Pulsed wave renal color doppler ultrasound was performed in 3 goats out of the 20 with the aim to generate reference images of renal vasculature in healthy goats. The mean±S.E. values of renal length, renal height, horizontal diameter of renal sinus, vertical diameter of renal sinus and diameter of renal pelvis for right kidney were 6.11±0.09, 3.26±0.08, 3.01±0.11, 1.32±0.03, 1.05±0.03, respectively while for left kidney these values were 6.02±0.09 and 3.35±0.07, 2.67±0.12, 1.14±0.06, 1.10±0.07 cm. The ureters could not be visualized in any of the goats. The distended bladder was seen as anechoic circular structure surrounded by a smooth echogenic wall with a mean thickness of 1.65+0.06 mm. No significant difference was observed in the measurements of both kidneys except in dimensions of renal sinus. Moderately positive correlation was found between renal size and body weight of goats. It was concluded that ultrasound is an easy, rapid and non-invasive method to evaluate echotexture and morphometry of structures of urinary system.

    Isolation, identification and molecular characterization of nontyphoidal Salmonella and listeria SPP. from foods of animal origin
    (G.B. Pant University of Agriculture and Technology, Pantnagar, District Udham Singh Nagar, Uttarakhand. PIN - 263145, 2022-07) Gunjiyal, Harshita; Maansi
    Non-Typhoidal Salmonella and Listeria are the two bacterial food-borne organisms that pose a major impact to the food sector worldwide. In addition, the emergence of multi-drug resistant organisms makes food-borne illnesses more severe. In view of this, the present study aims to ascertain the occurrence of non-typhoidal Salmonella and Listeria organisms in foods and their antimicrobial resistance profiles isolated from animal origin foods of four districts belonging to Kumaon region of Uttarakhand. A total of 250 samples comprising raw milk (n=141), milk products (n=59) and poultry meat (n=50) were collected randomly from multiple vendors, dairy farms, locality, butcher shops and screened for the presence of non-typhoidal Salmonella and Listeria organisms. The bacteria were isolated using culture method and biochemical identification was performed as per conventional method. Further, molecular characterization was done for confirmation. Antibiotic susceptibility testing was performed for the obtained isolates against a set of 12 antibiotics belonging to 9 different classes for Salmonella spp. and 8 different classes for Listeria spp. using the standard Kirby Bauer disc diffusion method. Salmonella spp. was detected in 7.2%; 18/250 and Listeria spp. in 2.4%; 6/250 of the 250 food samples studied. None of the Listeria isolates was found to be belonging to L. monocytogenes. Serotyping of Salmonella isolates revealed that S. Typhimurium and S. Weltevreden correspond to the dominant serotypes recording (4/18; 22.22%) higher serovar occurrence than S. Kentucky (2/18; 11.11%), S. Infantis (2/18; 11.11%). Rest were untypable (6/18; 33.33%). U.S Nagar harbored more Salmonella spp. (12.5%) followed by Nainital district (3.90%). On the other hand, Nainital district (3.12%) was found to harbor more Listeria spp. than U.S Nagar (1.9%). On subjection to antimicrobial susceptibility testing, Salmonella isolates showed varying degree of sensitivity to Co-trimoxazole (55.55%), co-resistance to Gentamicin and Chloramphenicol (44.44%). Complete phenotypic resistance (100%) was found for Cefotaxime and Erythromycin followed by Nalidixic acid (72.22%). Out of 18 obtained Salmonella isolates, 14 isolates (77.77%) were multi-drug resistant. A total of 12 different antimicrobial resistance patterns were observed. On the other hand, Listeria spp. were completely susceptible (100%) to Vancomycin, Chloramphenicol and Ampicillin. Complete resistance (100%) was found for Kanamycin and Tetracycline followed by Amikacin (83.33%). Out of six obtained isolates for Listeria spp. five isolates (5/6; 83.3%) were multi-drug resistant. A total of 5 different antimicrobial resistance patterns were observed which can be related to the non-judicious administration of antibiotics during both prophylaxis and treatment. Therefore, this study warrants careful consideration towards adopting hygienic measures and consumption of properly cooked food along with judicious use of antibiotics.

    (G.B. Pant University of Agriculture and Technology, Pantnagar, District Udham Singh Nagar, Uttarakhand. PIN - 263145, 2022-08) Nayal, Kalicharan; Anil Kumar
    In the present investigation, a feeding trial of 12 weeks of duration was conducted on 96 Uttara layers of 20 week age to study the effect of dietary supplementation of Arjun (Terminalia arjuna) bark powder on the production performance, egg quality parameters, egg composition, haemato-biochemical parameters, humoral immune response and economics of egg production. The laying hens were randomly divided in to four treatment groups (T0, T1, T2 and T3) four replicates of 6 birds each. The different groups were supplemented with Arjun bark powder at 0, 1g, 2g, 4g/100gm respectively to standard feed. Egg production, Egg quality parameters and Egg composition were studied in different Phase Ⅰ (26th week of age), Phase Ⅱ(32nd week of age) and overall period. At the end of Phase Ⅰ and Phase Ⅱ blood was collected for haematobiochemical parameter analysis. The results of the present trial indicate that dietary inclusion of Arjun bark powder increase egg production, Egg weight and improve Feed conversion ratio significantly (P≤0.05) in T2 group. The shell thickness increases significantly however no significant difference observed in other egg quality traits. The blood picture revealed that Hb, PCV, TEC and TLC values in Arjun bark supplemented groups are significantly improved. No significant difference was observed in egg composition parameters. Serum glucose, cholesterol, LDL, SGOT and SGPT values in Arjun bark supplemented groups decreases significantly and HDL value increases significantly however no significant difference observed in other biochemical parameters. The average serum immunoglobulin concentration increases significantly in Arjun bark supplemented group. The average feed cost per dozen egg (Rs) decreases significantly in Arjun bark supplemented group. From the results of present study it can be concluded that Arjun bark can be used as herbal feed additive/ phytobiotc in poultry diet for higher production and enhanced immunity by incorporating 2 percent of Arjun (Terminalia arjuna) bark powder in the basal diet of Uttara chicken.
