When does peak egg production occur in premium Hy-Line Brown layers, and how should feed formulation be adjusted to prevent a post-peak dip?

Commercial brown layers like Hy-Line Brown typically reach their physiological peak egg production (often exceeding 95-96% lay) between 25 and 28 weeks of age. To prevent a post-peak production dip—where egg lay drops suddenly due to energy depletion—nutritional adjustments must be made proactively around 21 to 23 weeks. As production rises, feed intake can lag behind the bird's high calcium and amino acid requirements. Nutritionists must formulate a highly dense pre-peak/peak feed containing at least 4.0-4.2% calcium, 0.42% methionine, and balanced metabolizable energy (around 2750 kcal/kg). This supports both high egg output and continued skeletal growth. Nutritional profiles can be studied in the Poultry Encyclopedia, feed pre-mixes and toxin binders bought on Poultry Plaza, daily feed raw material rates tracked on Poultry Rates, and peak-production flocks listed on Murghi Mandi.
