Dr. MN Balakrishnan Nair (PhD, MSc) is Head of the Centre for Ethno-veterinary Science and Practices at TDU. He has more than 38 years of research and teaching experience, and has with organizations such as Sardar Patel University, Department of Botany at University of Delhi, UPM Malaysia, Peermade Development Society and IIM Ahmedabad before joining TDU. An avid traveler, Dr. Nair has visited 23 countries as well. He has 38 peer reviewed papers, 6 books, 7 chapters in the books, and 29 Communications to Scientific Conferences (both national and international).


  • Documented Ethno-veterinary practices from 24 locations in 10 states of India
  • Rapidly assessed them using classical Ayurveda knowledge and established that 353 formulations out of 441 are safe and efficacious
  • In-Vitro antimicrobial activity of the extracts of the herbal formulation against mastitis had inhibitory activity against Escherichia coli (E. coli) and Staphylococcus aureus.
  • Clinical study using traditional formulation for mastitis showed that somatic cell counts (SCC), electrical conductivity (EC) and pH of the milk become normal within 6 days indicating cure of mastitis
  • Shown that traditional medicine can be used during dry period to reduce the incidence of mastitis and reduce retention of placenta (ROP)
  • Demonstrated that the antibiotic residue in the milk can be reduced by 88% in one year time
  • Demonstrated that adopting the Ethno-veterinary science and practices to combat infectious diseases in livestock has been a key game changer in reducing the use of antibiotic and other veterinary drugs in veterinary practices
  • Working with NDDB, AMUL, BAIF, 30 MILK Unions from 14 states, Government of Sikkim and Haryana
  • Trained on EVP: 1050 (61 PG Diploma) Veterinarians, 550 village resource persons, 37 Officers from the various Milk unions and 30,000 farmers. We are reaching now millions of famers through these organizations and they are all saving large amount of money as the formulations are very cost effective
  • Working with Natural Livestock Farming (NLF) Netherlands, Ethiopia and Uganda
  • Conducted exchange programme for vets and farmers from these counties to India and India to these counties
  • Studied 240 species of wood including Scanning Electron Microscope, developed a classification of vestured pits and helical thickening in relation to its function and its Utility in seasoning and preservative treatment of wood
  • Developed sustainable tapping of gum in Sterculiaurens (commercially known as gum karaya), oleo-gum-resin from Commiphoa weightii (commercially known as Guggal) and other species
  • Documented 435 LHT for 61 prioritized health conditions, assessed 388 are safe and efficacious
  • Established 21,454 HHGs in 451 villages,
  • Trained 2083 Women Village Resource Persons (VRPs) to use Medicinal plant for PHC needs
  • Intervention impact analysis indicate 70 to 100% cure for PHC and 88% reduction of family expenditure for PHC

Current Interests:

Field of study

  • Ethno-veterinary practices – Documentation, Rapid assessment, validation and promotion through mainstreaming them in veterinary curriculum, training vets, farmers and Dairy professionals to reduce antimicrobial use in dairy production and associated residues in the animal products and AMR
  • Medicinal plants and Primary health care – Documentation of Local health traditions, Rapid assessment, validation and Promotion through establishment of HHG, training, and capacity building to use them for PHC
  • Trans-disciplinary research
  • Forest products- wood structure in relation to adaptive morphology, seasoning and preservation, cambial growth, gum, gum-resin secretion, their sustainable tapping and uses.

On-going Research Projects / Grants / Specific Research Activities:

  • DABUR Guggulu harvest studies -“Sustainable tapping of Guggul (Oleo-gum-resin) from CommiphoraWightii (Arnott) Bhandari
  • “Management of antibiotic resistance pathogens in Clinical mastitis by Ethnoveterinary formulations”
  • Training of trainers in Validated EVP & Veterinary Ayurveda for Veterinarians: (Co.PI),at AMUL Dairy, Doodh Sagar Diary, Baroda dairy, Gokul Dairy, Abbott, Govt. of Haryana and Punjab
