When should the transition to pre-lay or peak-lay feed occur in Shaver White white layer hens under peak lay rate preservation (target over 95%)?

Feed phase transitions must be managed carefully based on production percentage and flock age. Transitioning Shaver White white layer hens too early or late can cause intestinal stress and slow down egg production, while incorrect calcium levels cause Fatty Liver Hemorrhagic Syndrome (FLHS from high-energy feeds). Monitoring peak lay rate preservation (target over 95%) and using step-up lighting program optimization (during pre-lay to laying phase) 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.
