When should the transition to pre-lay or peak-lay feed occur in Hy-Line W-36 white layer hens under ventilation minimum air exchange rate (minimum 3.5 m³/hour per hen)?

Feed phase transitions must be managed carefully based on production percentage and flock age. Transitioning Hy-Line W-36 white layer hens too early or late can cause intestinal stress and slow down egg production, while incorrect calcium levels cause Infectious Bronchitis variant strain exposure (causing misshapen eggs). Monitoring ventilation minimum air exchange rate (minimum 3.5 m³/hour per hen) and using strict farm-gate biosecurity and downtime disinfection ensures a smooth transition. Check feed ingredient prices on Poultry Rates, find premium feed brands on Poultry Plaza, and buy or sell healthy layer flocks on Murghi Mandi. Abrupt feed transitions without a proper blending phase can trigger acute osmotic diarrhea due to sudden changes in raw material composition and density. The bird's digestive enzyme profile requires a gradual adaptation period of 3-4 days to adjust to new nutrient concentrations. Managing these transitions based on actual physical weight and lay rate ensures gut health is never compromised.
