Short CV

Necmettin Ceylan is currently a Professor at the Department of Animal Science, Faculty of Agriculture of Ankara University, Turkey. He received both his M.Sc. and Ph.D. from Ankara University. He has conducted laying hen researches during his stay at University of Nebraska, USA between years 1996-1998 as post doc. He is member of Working Group 2 (Nutrition) of WPSA and Association of Scientific Animal Nutrition.

His researches in poultry nutrition actively involved in applied nutrition trials of broilers and laying hens including feed ingredients and feed additives such as amino acids, minerals and bioactive supplements, exogenous enzymes, organic acids related to growth, performance, gut health and meat and egg quality. 

He has been also conducting R&D projects with Beypiliç , one of the biggest broiler integration company in Turkey, on broiler nutrition and feeds, and currently completed over 30 trials since 2006.

He has published  25 peer reviewed papers in web of science journals, over 40 published articles and 35 abstracts in national and international conferences and meetings.
