Jianxia Wang recently earned her PhD in Animal Nutrition from Humboldt University in Berlin, Germany. Originally from Wuhan, China, she completed her B.S. at Wuhan Huazhong Agricultural University and her M.S. at the Chinese Academy of Sciences in Beijing. With 12 years of experience in animal nutrition at the Academy of Sciences, her research focused on feed additives and feeding management. She later worked as a technical service executive for the Chinese subsidiary of Continental Grain Company in Beijing and Hong Kong. In Germany, her research concentrated on poultry nutrition, particularly the effects of ambient temperature on poultry metabolism in tropical and subtropical regions. High ambient temperatures pose significant stress for poultry, affecting the profitability of chicken meat and egg production globally. This stress leads to substantial economic losses in poultry farming due to increased mortality and reduced growth. The study aims to utilize major genes related to feather reduction and necked neck or frizzle feather structures in broilers, which exhibit better heat tolerance, to enhance zootechnical performance and energy metabolism efficiency under high temperatures. This publication offers valuable insights and recommendations for poultry farmers and agricultural advisors, particularly in tropical and subtropical areas.
