Winter is the peak season for goose fatty liver syndrome. Factors such as low-temperature environments and adjustments in feeding management can easily lead to abnormal fat deposition in the liver of geese, resulting in economic losses for poultry farmers. Understanding the etiological factors of this disease and implementing effective prevention and control measures, particularly the rational use of auxiliary products in poultry farming, can significantly reduce the risk of disease occurrence.
一. High Incidence Triggers of Winter Goose Fatty Liver Syndrome.
1. Worsening Nutritional Imbalance (Prolonged Feeding of Low-Protein Feed) In winter, geese are primarily fed high-energy diets such as corn and grains, which are high in calories but low in protein. Coupled with reduced physical activity in winter, the excess calories cannot be effectively absorbed, leading to continuous fat deposition in the liver. Additionally, if the feed lacks key nutrients such as choline, biotin, and B vitamins, fat cannot be properly transported out of the liver, further exacerbating fatty liver disease. Furthermore, if the winter feed is insufficient in calcium content, geese may experience decreased egg production without reduced feed intake, with excess nutrients being converted into fat, which also contributes to the development of fatty liver.
2. Dual Effects of Winter Environment and Stress (Closed Goose Coops) During winter, goose coops are often excessively sealed to maintain warmth, leading to high humidity and poor ventilation. Combined with stress factors such as sudden temperature drops, disease outbreaks, and insufficient water intake, these conditions directly impair the liver function of geese. Concurrently, the significantly reduced physical activity in winter slows down fat metabolism, creating a predisposing risk for the development of fatty liver disease.
3. Potential risks of feed contamination and drug abuse (improper feed storage) Improper winter feed storage can easily lead to the proliferation of Aspergillus flavus, whose toxins may cause liver damage. Prolonged administration of antibiotics to geese for disease prevention can also disrupt normal liver metabolism, inducing fatty liver disease.
