Where does fat deposition (lipid storage) occur within the body of over-fed, obese brown layers, leading to fatty liver hemorrhagic syndrome?

In high-production brown layers, over-feeding or high-carbohydrate diets can lead to excessive fat deposition and obesity. This lipid storage is localized in two main anatomical regions: the abdominal cavity (as massive abdominal fat pads) and, more dangerously, inside the parenchymal cells (hepatocytes) of the liver. When fat accumulation in the hepatocytes exceeds 30% of the liver's dry weight, it leads to Fatty Liver Hemorrhagic Syndrome (FLHS). The liver becomes swollen, yellow, and structurally fragile (friable). The excessive fat compromises the structural integrity of the hepatic blood vessels, making the liver prone to rupture and fatal subcapsular hemorrhage, especially during the physical straining of egg-laying. Adding lipotropic nutrients like Choline Chloride and L-Carnitine to the feed is essential to mobilize these fats. Farmers can research nutritional pathology in the Poultry Encyclopedia, buy choline chloride feed additives on Poultry Plaza, monitor daily raw grain rates on Poultry Rates, and list healthy layer flocks on Murghi Mandi.
