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.

    SURGICAL MANAGEMENT OF AVIAN WING INJURIES FOR REINSTATEMENT OF AERODYNAMICS
    (G. B. Pant University of Agriculture & Technology, Pantnagar-263145, 2023-05) Bora, Mony; Das, Arup Kumar
    In the present study, 548 injured birds with wing injuries were included, irrespective of the species that were rescued by Raksha (Wildlife Rescue Centre), based in Jaipur, Rajasthan. All rescued birds were placed in pre-heated rooms and stabilized with pre-medication: clindamycin at a dose rate of 100 mg/Kg intramuscularly, meloxicam at a dose rate of 0.5 mg/Kg intramuscularly and in cases of fracture, butorphanol at a dosage of 0.1 mg/Kg intramuscularly. All patients received subcutaneous fluid at a dosage of 20 ml/Kg body weight. All procedures, from feather plucking to surgical site scrubbing, were performed under general anaesthesia to minimize stress in birds. The birds were anaesthetized using isoflurane inhalation anaesthesia delivered through a non-rebreathing circuit. Fractured pectoral limb cases were treated by intra-medullary pinning using K-wire, while lacerated patagium cases were repaired by suturing the patagial ligament using the Bunnell-Mayer suture pattern. The injured wings of all cases were then immobilized in the normal flexed position using ‘Figure-of-eight’ bandaging technique with Vetrap. Each bird received post-operative medication and care throughout the surgical recovery period. Clinical parameters, such as the healing of surgical wounds and body weight of birds, were recorded every other day after surgery. For fractured cases, radiography was performed as needed to assess callus formation. After the bandage was removed seven days post-surgery, the birds were assessed for their flight ability. The patagial lacerations took 7-10 days to heal and fracture cases showed radiological union within ten days. The average time taken for patagial laceration cases to restore flight was 15 days. For radiusulnar fractures, the time period was 44 days and for humerus fractures the time period was 62 days. The results of the study indicated that 48 percent (265) of birds were released, 16.4 percent (90) received lifelong rehabilitation and 35 percent (193) experienced mortality. Based on the observed parameters, it was concluded that the use of K-wire in the intra-medullary pinning technique is applicable, approachable and easy to perform, yielding good results in the restoration of flight. In addition to this, the Bunnell-Mayer suture pattern proved effective in achieving proper alignment and apposition of the patagial ligament. Also, the application of post-surgery physical therapy has been beneficial in preserving and rehabilitating limb function, particularly by improving joint mobility, muscle tone and strength. Hence, use of strategic avian management techniques, which entail proficient handling procedures, meticulous pre- and post-operative care and tailored housing solutions that cater to the specific needs of each species and their dietary habits, have been found to be highly effective in reducing stress levels and promoting recovery of birds.

    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.

    (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

    Studies on the effects of tiletamine-zolazepam, propofol and sevoflurane anaesthesia in dexmedetomidine and butorphanol premedicated dogs
    (G.B. Pant University of Agriculture and Technology, Pantnagar, District Udham Singh Nagar, Uttarakhand. PIN - 263145, 2022-07) Tiwari, Kanika; Jadon, Narendra Singh
    Thirty-six adult dogs used in the study were randomly divided into 6 subgroups (A-1, A-2, A-3, B-1, B-2 and B-3). All the dogs were administered with atropine sulphate at the dose rate of 0.04 mg/kg body weight subcutaneously. After five minutes, animals of group A-2 and B-2 were premedicated with dexmedetomidine whereas animals of group A-3 and B-3 were premedicated with dexmedetomidine and butorphanol at the dose rate of 5 μg/kg body weight and 0.1 mg/kg body weight intravenously. The animals of groups A-1, A-2, A-3, B-1, B-2 and B-3 induced with tiletamine-zolazepam and propofol at the dose rate of 6.66±0.06 mg/kg iv, 1.86±0.11 mg/kg iv, 1.26±0.02 mg/kg iv, 5±0.06 mg/kg iv, 2.56±0.01 mg/kg iv and 2.16±0.01 mg/kg iv respectively. Anaesthesia was maintained with sevoflurane and MAC of sevoflurane was determined by tail clamp method in all the animals. The level of anaesthesia was determined by observing various clinical (induction time, duration of anaesthesia, muscle relaxation, pedal reflex, palpebral reflex, analgesia, recovery time, sternal recumbency time, standing time, complete recovery time, required doses of induction agents and reduction in the % MAC of sevoflurane, physiological and haemodynamic (rectal temperature, heart rate, respiration rate, blood pressure, haemoglobin oxygen saturation (SpO2), electrocardiography), haematological (haemoglobin, total erythrocyte count, total leucocyte count, differential leucocyte count) and biochemical (serum glucose, total protein, serum albumin, serum urea nitrogen, serum creatinine, alanine amino transferase, aspartate amino transferase) parameters. Clinical efficacy of the anaesthetic combination was determined by performing various surgical operations.The mean induction time reduced in the animals of groups A-2, A-3, B-2 and B-3 after the administration of preanaesthetic drugs whereas longer duration of anaesthesia, recovery time, sterna recumbency time, standing time and complete recovery time were observed in the animals of group A-2, A-3, B-2 and B-3 after the administration of preanaesthetic drugs. Adequate muscle relaxation and excellent analgesia was observed in the post-induction period in all the animals of different groups. Pedal and palpebral reflexes were very weak after the induction with tiletamine-zolazepam in group A-1, A-2 and A-3 whereas it was completely lost after the induction with propofol in group B-1, B-2 and B-3. Preanaesthetic administration of dexmedetomidine and butorphanol reduced the induction dose of drugs (propofol and tiletamine-zolazepam) and MAC of sevoflurane. The rectal temperature, heart rate and respiration rate showed significant decrease at various time interval and reached to the baseline values by 24 hours post-anaesthesia. SAP, DAP and MAP was decreased non-significantly in group A-1 and B-1 whereas it showed a significant increase in group A-2, A-3, B-2 and B-3 at respective time interval. Significant decrease in haemoglobin oxygen saturation was observed after administration of induction agents. Significant reduction in PR interval was observed in animals of group A-1 whereas non-significant changes were observed in QRS and QT interval in all the groups of animals. Inverted T-wave and sinus dysrhythmia were observed after administration of dexmedetomidine whereas sinus tachycardia was observed after induction with tiletamine-zolazepam. Transient changes within physiological limits were observed in haemato-biochemical parameters which reached to baseline values by 24 hours. On the basis of above mentioned parameters, it was observed that the anaesthetic combinations used in the study have least deleterious effects on different body systems and the most efficacious anaesthetic combination was atropine sulphate-dexmedetomidine-butorphanol-tiletamine-zolazepam-sevoflurane

    (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.
