Split-feeding as a sustainable feeding strategy for improving egg production and quality, nutrient digestibility, and environmental impact in laying hens.

ABSTRACT: This study evaluated the effects of split feeding on production performance, egg quality, nutrient digestibility, odor emissions, and economic benefits in laying hens. A total of 468 Hy-Line Brown hens, aged 63 weeks, were divided into three dietary treatments over 13 weeks. The control group received a single basal diet, while two split-feeding groups (TRT1 and TRT2) received diets differing in nutrient composition between the morning and afternoon. TRT1 and TRT2 contained 10 % and 15 % less crude protein (CP), respectively, compared to CON. TRT1 maintained the same levels of metabolizable energy, standardized ileal digestibility amino acids, calcium, and phosphorus as CON, while TRT2 had 5 % lower metabolizable energy, standardized ileal digestibility amino acids, and calcium, and 15 % l
