Dr. S.K. Sirohi, working as Senior Scientist, Dairy Cattle Nutrition Division, National Dairy Research Institute, Karnal joined Agricultural Research Service in 1993. Dr. Sirohi completed his post graduation and doctoral programme in Animal Nutrition from Indian Veterinary Research Institute, Izatnagar and National Dairy Research Institute, Karnal in the year 1988 and 1993. He has 19 years teaching, research and extension experience in the area of Animal Nutrition. His area of research interest is improvement of poor quality feeds, rumen manipulation and energy and protein nutrition. Presently, he is working in the area of mitigation of greenhouse gas methane in dairy animal through rumen microbial manipulations. He has published about 100 research publications in National and International journal of repute and also presented several lead/invited talk and more than 100 papers in different National or International workshop/conferences and training programmes. Dr. Sirohi has guided six postgraduate and one doctoral scholars and also written six books, and technical reports on various topics in the field of animal nutrition. Dr. Sirohi also visited France, Malaysia and Switzerland under different programmes. He is a life member of Animal Nutrition Association, Animal Nutrition Society of India, Indian Society of Animal Production, Nutrition Scientist Forum and Indian Science Congress etc.

Dr. T.K. Walli after graduating in Dairy Production from NDRI, Karnal, in 1966, pursued his post graduate studies as well as his doctoral programme from the same institute in Animal Nutrition. He joined the faculty of Dairy Cattle Nutrition Division at NDRI in 1968 and served there in various capacities, including as Principal Scientist and Head of the Division, before his retirement from the institute in 2006. In 1975, he was offered IAEA’s 6 months fellowship to conduct research at NIRD, Reading, UK. In 1988, under Indo-Dutch fellowship programme at Rowett, Research Institute, Aberdeen, UK, he worked with Dr. Bob Orskov on genetic variability in straw quality. His research work on establishing the relevance of bypass protein feeding in tropics in improving growth rate, milk production work on establishing the relevance of bypass protein feeding in tropics in improving growth rate, milk production and reproductive efficiencies in ruminants has been highly acclaimed and the technology is now commercialized by NDDB and the feed industry. After his retirement, Dr. Walli acted as Chief Technical Advisor to Poshak Agrivet and worked relentlessly for the success and propagation of straw based densified complete feed block technology, for which FAO has now published a bulletin with he as the first author. Dr. Walli has served as Secretary ANSI, and under his Presidentship, ANSI organized an International Nutrition Conference in 2007. He also served as Editor, Indian Journal of Dairy Science for 6 years. Dr. Walli has made presentations in many International conferences/meetings, including in countries like Pakistan, Vietnam and Ethiopia (ILRI). The proceedings of the FAO sponsored e-Conference (2011) carry 4 chapters written by Dr. Walli. At present he is a Member QRT for NIANP, Bangalore. For his significant contribution in the field of animal nutrition, Dr. Walli has been honored with Dr. D. Sunderesan Award in 2003, IDA’s Fellowship Award in 2009 and Life Time Achievement Award by ISBD, in 2011.

Dr. B. Singh passed B.Sc. (Dairy Husbandary) in 1969 and M.Sc Dairying (Animal Nutrition) in 1972 from NDRI, Karnal. He earned his Ph.D. (Animal Nutrition) degree from HPKV, Palampur (HP) in 1990. Dr. Singh was awarded Glaxo Merit Scholarship in B.Sc (Dairying), ICAR Junior Fellowship, Honours Certificate in Ph.D, S.K. Ranjhan Best Thesis (Ph.D) Award, Best paper Award (1997-99) of Animal Nutrition Society of India, Community Award by Rotary International, Palampur. Dr. Singh joined ARS in 1976 as Scientist S-l and was promoted to Principal Scientist in 1998. He was Scientist Incharge of Regional Station of IVRI, Palampur from 1990 to 2005 and transferred to NDRI, Karnal in July, 2005 and retired from service in the year 2009. Has research experience of 35 years and research interests include rumen metabolism, anti-nutritional factors and plant secondary metabolities and degradation kinetics. He has over 130 research papers in various prestigious peer reviewed journals of international repute. He has also been the Executive Editor of Indian Journal of Dairy Science. Dr. Singh visited Myanmar in 2001 and 2003, Zanzibar, Tanzania in 2002 as Expert under joint FAO/IAEA programmes. He has also visited Canada, England, Germany and Thailand for Scientific deliberations.

Dr. Nasib Singh completed his M.Sc degree in Microbiology with distinction (Gold Medal) from Kurukshetra University in 2001. He then joined doctoral programme at Central Drug Research Institute, Lucknow and worked on the development of in vitro and in vivo drug screening models against visceral leishmaniasis, a neglected tropical infectious disease. In 2008, Dr. Singh moved to the University of Texas Medical Branch (USA) for postdoctoral fellowship and worked on molecular and immunological aspects of host-pathogens interactions during Leishmania and Francisella tularensis. Presently, Dr. Singh is engaged in deciphering the rumen microbial diversity in ruminants and the impact of plant/microbes based feed additives on methanogenesis and utilization of poor quality fibrous feeds. He was also a recipient of Junior and Senior Research Fellowship Awarded by CSIR, New Delhi. Dr. Singh made several significant scientific contributions to a number of areas related to antileishmanial drug development using transgenic Leishmania parasites, immunomodulation, host-pathogen biology and rumen microbial ecology. These studies have resulted in 16 original research papers in national and international refereed journals alongwith several book chapters.
