Dr. T.K. Walli is working as Principal
Scientist (Animal Nutrition) at NDRI, Karnal
since 1998. Earlier he held the charge of
Head (officiating), Dairy Cattle Nutrition
Division at NDRI, Karnal, from Dec. 2000
to Feb. 2003. Dr. Walli joined B. Sc. Dairying
Course at NDRI in 1962 and later obtained
his post graduation in Dairy husbandry in
1968. He joined ICAR projects at NDRI, Karnal
on "Production, purification, characterisation
of rennin from living calves and its suitability
for cheese manufacture, using abomasal fistulation
technique for the first time, under the
leadership of Dr. N.C.Ganguli. Dr. Walli
was awarded IAEA fellowship for a period
of 6 months to work on "Measurement
of absorption rates of fatty acids from
the intestines of re-entrant cannulated
sheep," at National Institute for Research
in Dairying, Reading, UK. On the submission
of project report, IAEA awarded a merit
certificate. Under the Indo-Dutch Project
on "Bioconversion of crop residues
as ruminant feed", he conducted research
on biological (using aerobic, lignolytic
fungi) and chemical (urea) treatments of
straws to improve its utilization in the
ruminant system. Dr. Walli was also awarded
a three months fellowship under Indo-Dutch
project to conduct research on "Genetic
variability in the nutritional quality of
rice and wheat straw", at the prestigious
Rowett Research Institute, Aberdeen, UK,
under the world famous Animal Nutritionist,
Dr. E.R.Oroskov. Under the NARP World Bank
Project on Animal Biotechnology, he worked
on "Manipulation of rumen bacteria
and fungi for enhancing fibre digestion
in rumen". Anaerobic fungi was isolated
for the first time from the rumen of buffaloes,
and its cellulolytic enzymes partially purified.
Dr. Walli's most significant contribution
is in the area of "Development of Bypass
Protein Technology", studying its different
aspects and its relevance under Indian conditions,
which included, evaluation of bypassability
of proteinous feeds, increasing the bypassability
of some highly degradable oil cakes (using
heat and formaldehyde treatment), measurements
of the flow rates of microbial protein and
amino acids at abosmasum, and the production
performance of high producing dairy animals,
in terms of growth, health, milk yield,
milk composition and the milk quality for
human consumption, on feeding of bypass
proteins. He was also the leader of NDDB/NDRI
collaborative research project on "Feeding
of bypass protein for increasing milk production
in crossbred cows" and also published
its final report. Dr. Walli has written
7 Book Chapters in "Handbook for Straw
Feeding systems" (K. Singh and J. B.
Schiere, eds. 1995). He has some 160 publications
to his credit, which include research papers
in Indian and International journals, lead
papers, review articles, popular articles
and a few technical bulletins. Dr. Walli
has been on the editorial board of :Indian
Journal of Animal Nutrition, Animal Nutrition
and Feed Technology, Indian Journal of Animal
Reproduction and Management, Indian Society
for Buffalo Development Journal and NDRI
News Letter. Presently Dr. Walli is the
Executive Editor of Indian Journal of Dairy
Science; Secretary, Animal Nutrition Society
of India and Vice President, Alumni Association
of NDRI, Karnal.
