Advances in poultry nutrition

摘要

NUTRITIONAL RESEARCH IN poultry has centred on issues related to identifying barriers to effective digestion and utilisation of nutrients, and on approaches for improving feed utilisation. Poultry nutritionists have increasingly combined their expertise with that of specialists in other biological sciences, including immunology, microbiology, histology and molecular biology.Although broilers and layers are highly efficient in converting feed to food products, they still excrete significant amounts of unutilised nutrients.
