With in short period of time, GADVASU has attained excellence in the field of livestock, poultry and fisheries production and health through integrated teaching, research and extension programmes and is producing quality human resources. GADVASU has a number of novel strengths.

Novel Strength I: Modern Infrastructural Facilities

Veterinary Clinical Sciences

  • Small Animal Laparoscopy and Endoscopy Units: For diagnosis, therapeutic and surgical interventions in Departments of Clinical Veterinary Medicine, Ethics and Jurisprudence and Surgery and Radiology.
  • Clinical Diagnostic Laboratory: More than 22,000 animals are registered annually for treatment and advice which included ruminants, equines and small animals. More than 10,000 clinical samples of blood, urine, faecal, body fluids and tissues are submitted to the clinical diagnostic laboratory for pathological (4500), parasitological (3500), biochemical (1500) and microbiological (500) investigations which aid in quick and accurate diagnosis of diseases. Radio-diagnostic facilities such as ultrasound, endoscopy, and digital radiography are available for diagnosis, therapeutic and surgical interventions. Approximately 2500 X-Rays and 1000 ultrasound scans are done every year.

Novel Strength II: Authentic Disease Diagnostic Facilities and Disease

  • Surveillance Mechanism: Modern state of the art molecular diagnostics centre has been developed for rapid diagnosis of animal diseases including Brucellosis, Rabies and Parasitic diseases.
  • Up gradation of Research Laboratories: The research laboratories various departments of university have been up graded to apply modern diagnostic and research approaches.

Sensitivity of detection of rabies by real time PCR was 62.5% and of skin biopsy samples was 71.4% respectively.
  • Immunohistochemistry has been established as more sensitive for detection of Rabies antigen in formalin fixed paraffin embedded tissue sections.
  • Diagnosis of Brucellosis was also conducted by PCR. Biotyping of 11 isolates revealed 8 biotypes 1, two isolates of biotype 3 and one isolate of biotype 2.
  • Epidemiology study of gastrointestinal parasites in Punjab was conducted on faecal samples wherein eggs/oocysts of T. vitulorum, Strongyloides spp., Eimeria spp. and Moniezia spp. were found.
  • Prevalence of Theileria annulata in tick vectors in Punjab was found to be higher in female ticks as well as in hot / dry climate.
  • Heat shock gene 70 has been cloned, sequences and characterized vis-à-vis heat stress in buffaloes. Major Histocompatability locus’s polymorphism and its relationship with growth and viability of broiler chickens.
  • Ultrasonography was standardized for the diagnosis of intestinal, hepatic, splenic and renal affections in the dairy animals. Ti is found that ultrasound could successfully diagnose and differentiate omasal impaction, abomasal impaction/dilatation, reticular abscess, reticulophrenic adhesions, focal and diffused peritonitis and Pericarditis. Modified technique of rumenotomy was standardized to treat recumbent animals suffering from acidosis.

Disease Diagnosis:

  • A significant work has been conducted to assess the ante mortem detection of rabies with high sensitivity from hair follicles for the first time in animals by molecular approaches. For diagnosis of rabies, Immunohistochemistry which is more sensitive for detection of Rabies antigen in formalin fixed paraffin embedded tissue sections has been established.

  • Incidence of bovine tuberculosis was studied by screening cattle and buffaloes from different districts of Punjab using single intra-dermal test. About (5.88%) cattle and (2.40%) buffaloes were found to be positive.
  • In the year 2009-10, 6 outbreaks of FMD in different villages of Punjab were recorded and many outbreaks remained unreported. Epidemiology studies revealed re-emergence of disease on large scale. Out of 1198 animals in different farms of state, 221 animals were affected and 9 deaths recorded.
  • One outbreak of swine fever in pig farm was recorded. There were 40 animals in this farm, 12 were affected and 7 succumbed to disease.
  • Surgical infections of the abdomen were diagnosed in 283 cows and buffaloes with a primary complaint of inappetance or anorexia and absence of faecal output. Omasal impaction was found to be associated with advanced pregnancy or early lactation was associated with majority of the abdominal disorders. The information from 5 different district Co-operative milk plants was collected on milk procurement pattern its quantity and value, price of raw milk procured, quality of raw milk, development of milk into different processed milk products, utilization pattern. Approximately 90% of milk is processed as STD milk, DTM and FCM in all the plants. The services provided by the milk plants such as AI facility, Bulk milk coolers & automatic milk collection units has increased manifold in the last 5 years.
  • A survey of the central districts of Punjab and sub-mountainous regions revealed that there is a widespread subclinical deficiency of Ca, P, Cu, I and Zn in both cattle and buffaloes. A comparatively higher prevalence of I deficiency has been recorded in cattle than in buffaloes. However, Fluorosis is endemic in dairy animals in four south-western districts of Punjab.

  • Non surgical embryo transfer was attempted in crossbreed cows at Ludhiana and Patiala centres respectively. A total of 90 transferable embryos were frozen.

Novel Strength IV: Need Based Research for Punjab

AQUA CULTURE

  • About 1.25 lakh ha of land in south-west districts of Punjab (Mukatsar, Ferozepur, Faridkot, Bathinda and Mansa) are affected by salinity and water logging. Prolonged water logging and continuous evaporation of water has resulted in heavy accumulation of salts which has made the land unfit for crop production.
  • GADVASU, Ludhiana has developed and demonstrated technology to produce fish in such land. Carp productivity of 2.5 ton/ha/yr has been achieved by manipulation of salinity through addition of canal water (with salinity below 10 ppt) in south-western Punjab, thus ensuring the earning of Rs 75,000-90,000 per hectare from their zero earning land.
  • The Indian Council of Agricultural Research (ICAR) has sanctioned a prestigious Niche Area Excellence Project in Fisheries to undertake region-specific research for sustainable growth of aquaculture in Punjab with major focus on developing suitable aquaculture package for Inland Saline waters/waterlogged areas in the south-west districts and diversification of carp culture with high value species. Azolla culture demonstration unit and duckweed based bioremediation technology were developed and were evaluated for their utilization as livestock feed.
  • Rearing of brood stock and breeding of common carp in these waters has been established. Carp seed produced in saline water is expected to grow faster than the seed procured from freshwater.
  • Low cost fish feeds formulated by using non-conventional feed resources (pressmud, molasses, poultry hatchery waste) which reduced the feed cost by 25-50%.
  • The technology developed by the university has already been accepted by the Punjab State Farmer’s Commission and certain NGO’s for its wider application in the State and elsewhere.

DRUG EFFICACY:

  • High degree of Acaricide resistance was found in Rhipicephalus microplus with Deltamethrin (96.6%) and Cypermethrine (93.3%).  
  • Study of antibiotic sensitivity of Brucella abortus revealed 100% sensitivity to tetracycline and ampicillin. It was found to be resistant to penicillin.
  • The drug sensitivity test against almost all bacterial isolates from the skin affections in fish sensitivity revealed that chloramphenical was the drug of choice

RESIDUE ANALYSIS IN THE FOOD OF ANIMAL ORIGIN:

  • Pesticides residue analysis laboratory has been established fully equipped with GC, HPLC, and GC-MS. The multiple residue methods for milk, meat, water, ghee, animal concentrate feed, green fodder and water have been standardized. The predominant pesticide residues encountered in samples are of DDT, its metabolite, HCH and endosulfan, etc. The residue work have been initiated in fish, fish feed and fish pond water samples.
  • The research on food borne pathogens and food safety in food samples of animal origin revealed shigatoxic Escherichia coli, enterotoxigenic Aeromonas species, pathogenic Bacillus cereus, etc. These pathogens were also molecularly characterized for their virulence potential and drug resistance genes. The research studies revealed that food borne pathogens pose a potential threat to public health.
  • Fipronil insecticide produced mild toxicosis and fluoride significant toxicosis in buffalo calves. However, the combined exposure of Fipronil and fluoride markedly enhanced the toxicosis in buffaloes with significant changes in toxicological, oxidative stress and biochemical parameters. 
  • Research on various parasitic zoonotic diseases viz. Echinococcosis, Cysticercosis, Cryptosporidiosis, Giardiasis conducted. The epidemiological studies on swine Cysticercosis and associated risk factors conducted. 
  • Seroprevalence studies on human hydatidoses were carried out. Samples have been collected from patients visiting Civil Medical Hospital Ludhiana, veterinary doctors, dairy farmers and dog handlers. Echinococcus IgG ELISA for E. granulosus and E. multilocularis was performed which indicated high prevalence. 
  • Prevalence studies on Cryptosporidium and Giardia intestinalis have been conducted. Cryptosporidium oocysts were detected from both diarrheic as well as non-diarrheic animals. Both shedding and intensity of shedding were significant in calves with diarrhea. The prevalence of the infection peaked in young calves between 0 and 30 days in both the diarrheic and non-diarrheic groups (86.4 and 66.6%, respectively). 

ANIMAL NUTRITION

  • Advances in animal nutrition includes Uromin-Lick, Rumen protected fat, natural fermented straw and silage from maize fodder.
  • Identified areas specific mineral imbalances in dairy animals in different regions of Punjab will be helpful in formulation of area specific mineral mixtures for different regions to improve production, reproduction and health of dairy animals.

TECHNOLOGICAL IMPROVIZATION

Power Generation from Dairy Waste:

  • The plant was set-up to curb environmental degradation and add valuable products back to the environment as the raw dung is being used as a fertilizer.
  • The university saves Rs 1, 71,000 a month in the form of electricity, slurry and carbon dioxide.
