Instant Insights: Alternative Sources of Protein for Poultry

Sahil Kalia is working as a Postdoctoral Associate in the Department of Animal Science at Cornell University. He has published various research articles, abstracts, book chapters in reputed journals including Nature Publishing Group. Dr Xin Gen Lei is Professor of Molecular Nutrition in the Department of Animal Science at Cornell University, USA. Professor Lei has an international reputation for his wide-ranging research in nutrition as well as algal biomass research. Amongst his many achievements, Professor Lei developed a new phytase enzyme that is now used in 46 countries to improve feed phosphorus bioavailability to animals and reduce their phosphorus excretion. He has won a number of awards from The American Society for Nutrition and the American Society of Animal Science. He is Associate Editor of the Journal of Nutrition as well as President of TEMA (Trace Elements in Man and Animals).
