Chicken fatty liver syndrome occurs more often in laying hens, especially in caged laying hens. Most chickens with fatty liver syndrome are in good condition and die suddenly without warning. However, the incidence of roosters in the farm is rare. The breeder should understand the specific causes of fatty liver in chickens and take effective prevention measures to reduce the economic losses of the farm.
1 Cause analysis
The diet of chickens lacks choline, inositol, V E and V B12 and other nutrients or nutrient content is insufficient. After eating, the chicken will accumulate excessive fat in the liver and cause disease. If the protein content of the diet provided by the chicken farm is low or the amino acids are insufficient, the energy in the chicken will be too high. More often, it causes a large amount of fat to deposit in the liver and body cavity. If the proportion of protein in the chicken's diet is too high or it is not suitable for the energy value, it will cause metabolic dysfunction and excessive fat deposition in the chicken body, which will lead to fatty liver syndrome. If the flock diet uses powdered calcium additives and the calcium content is very low, eggshell formation needs to pass a large amount of calcium, so the hen will eat too much feed and convert it into fat and deposit it in the liver and body cavity. Cause fatty liver syndrome. In addition, if the chickens drink hard water daily and the body lacks selenium, or usually lacks exercise, it may induce fatty liver syndrome. If in the hot season, it is more likely to induce fatty liver syndrome, and give Chickens fed colza cakes can also cause the disease.
2.Pathogenesis
The liver is an important place for fat synthesis in chickens. After body fat synthesis, it is transported to the body's blood in the form of very low-density lipoproteins, and the synthesis of apolipoprotein required for transportation is in methionine, serine, VE, and B vitamins.
