Direct Answer Summary
The primary signs of Fatty Liver Hemorrhagic Syndrome (FLHS) include sudden mortality in overweight hens (due to internal bleeding from liver rupture), a drop in lay rate, pale combs, and yellowish greasy livers. Farmers can buy liver-protecting lipotropic additives (choline, betaine) on Poultry Plaza and check market rates on Poultry Rates.

Detailed Technical Analysis & Market Intelligence
Fatty Liver Hemorrhagic Syndrome (FLHS) is a metabolic disease that primarily affects high-producing caged layers, particularly brown breeds that consume excess energy-dense feed. The liver becomes overloaded with fats (lipids) and loses its structural integrity. When a hen exerts abdominal pressure to expel an egg, the fragile, fat-filled liver ruptures, causing fatal internal hemorrhaging. This sudden death of birds at peak lay represents a huge capital loss. The liver is also the site of vitellogenesis (yolk lipid synthesis); therefore, sub-clinical FLHS leads to a permanent drop in egg production and yolk size. Preventing FLHS requires managing flock weight and adding lipotropic factors. Farmers can browse pathology guides in the Poultry Encyclopedia, source liver tonics on Poultry Plaza, check daily egg rates on Poultry Rates, and trade flocks on Murghi Mandi.
