Causes of fatty liver in laying hens

summary

Chicken fatty liver often occurs in laying hens, laying hens feeding cycle is long, a large amount of fat accumulated in the liver, gradually forming fatty liver. Most farmers will suddenly find that the good condition of the chicken is good. The dead chickens were characterized by a large amount of fat accumulation in abdominal cavity and subcutaneous, and blood clot under liver capsule. Now let's learn about it.

Causes of fatty liver in laying hens

One reason: the nutritional process is easy to lead to fatty liver, but lack of nutrition can also lead to fatty liver. The nutrient deficiency here refers to the deficiency of certain nutrients, such as choline chloride, vitamin E, vitamin B12 and methionine in the feed of laying hens. It participates in the synthesis of lipoproteins and assists lipoproteins to transport fat out of the liver. When these nutrients are deficient, the fat processed or transformed in the liver can not be transported out, and then it is deposited in the liver cells to form fatty liver.

The second reason: the amount of nutrition in the feed of chicken exceeds the normal life, production consumption and storage, and the excess part is converted into fat and deposited in the body, forming excessive adipose tissue, which makes the chicken obese. Excessive fat mainly deposited in the subcutaneous tissue, the inner side of the abdominal wall, around the kidney, around the stomach and liver. The excessive deposition of fat in hepatocytes seriously affects the physiological function of liver and causes liver hypertrophy.

The third reason is that the liver function is poor or damaged, which reduces the ability of the liver to synthesize lipoproteins and can not transport fat out in time and deposit in the liver. All kinds of viral diseases, missed hyperthermia, hepatobiliary diseases, as well as poisoning caused by heavy metals, aflatoxin, cottonseed meal and rapeseed meal, can cause great damage to liver function.

matters needing attention

In fact, any kind of disease does not exist alone, nor is it caused by a single factor. In particular, fatty liver disease is a chronic accumulation process, and is closely related to the health quality of chickens. Breeders should pay more attention to it.
