Layer Chick (0-8 Wks)
Layer Chick (0-8 Wks)
Identity
Initial layer feeding phase designed for controlled skeletal growth and early development of egg-type chicks.
Overview
Layer Chick (0-8 Wks) is the foundational feeding phase for commercial egg-type pullets, operating under BIS IS 1374 standards. Unlike fast-growing broilers, this diet controls skeletal growth, preventing metabolic complications or obesity. It restricts energy while providing a high crude protein concentration and a balanced amino acid profile to ensure balanced long-term layer health, supporting feathering and skeletal elongation.
