Thinking Caused by Laying Hens Liver Problems

With the large-scale development of laying hens production, the continuous emergence of old problems shows that many of the realities are not optimistic, and the problems cannot be ignored! The constant recurrence of liver problems, including the quality of eggshells in the later period, is not related to liver problems!

Let's first understand the five functions of the liver:

1. Metabolic function:

① Sugar metabolism: the starch and sugars in the feed are digested and absorbed through the intestine to provide energy for laying hens.

② Protein metabolism: The liver is the only organ for the synthesis of albumin in the body of laying hens. The production, maintenance and regulation of globulin, enzyme protein and plasma protein all require the participation of the liver, while the disposal of waste is carried out in the liver.

③ Fat metabolism: The synthesis and release of fat, the decomposition of fatty acids, the synthesis of cholesterol and phospholipids, and the synthesis and transport of lipoproteins are all carried out in the liver.

Vitamin metabolism: many vitamins such as A, B, C, D and K synthesis and storage are completed by the liver, liver dysfunction will appear abnormal vitamin metabolism.

⑤ Hormone metabolism: the liver is involved in the inactivation of hormones, and sexual hormone imbalance can occur when liver function is damaged for a long time.

2. Detoxification of the liver:

The liver is the largest detoxification organ of the body. Some harmful wastes such as oxygen free radicals and foreign poisons, toxins, and drug metabolism and decomposition products produced during the metabolism of the body are decomposed and oxidized in the liver. Substances are excreted from the body.

3. Digestive function of liver: bile produced and secreted by liver cells is transported to the gallbladder through the bile duct, and the gallbladder is concentrated and put into the small intestine to accelerate the digestion and absorption of fat.

4. Liver coagulation: Almost all coagulation factors are produced by the liver, and the liver plays an important role in regulating the dynamic balance of the two systems of coagulation and anticoagulation. Liver failure is often accompanied by massive hemorrhage and even death.

5. The immune function of the liver: the liver is the largest phagocytic system of reticuloendothelial cells, which can phagocytize, isolate and eliminate various pathogenic bacteria and antigens that invade and grow endogenously.

The liver is the largest gland in the body of laying hens. It participates in the metabolism, detoxification, bile production, blood coagulation, immunity and other functions of laying hens. It also plays a very important role in the production of heat and the regulation of water and electrolytes. A huge "chemical plant". Once the liver function declines or even fails, it directly affects the health of laying hens and even leads to death.

To this end, we should also fully understand and understand the physiological characteristics of the digestive system of laying hens and the characteristics of the nutritional needs of laying hens! Chicken itself has no teeth in the digestive system, so the nutritional requirements for feed are relatively high. It must be fully digestible and absorbable. At the same time, there must be enough crude fiber to promote gastrointestinal peristalsis so as to achieve balanced absorption and utilization of nutrition. For this reason, wheat bran is particularly important in the production process of laying hens. In order to maintain the normal laying performance, laying hens have a relatively high demand for protein and energy. For this reason, many breeding practitioners prepare the full-price material of laying hens into refined daily material with high nutrient concentration of pure energy and pure protein, which seriously affects the digestion and absorption function of chickens, resulting in the phenomenon of excess energy and protein in individual chickens! In serious cases, a series of premature aging problems such as liver yellowing, brittle and easy rupture and bleeding, egg laying performance, and eggshell quality decline (sand shell, thin shell, no shell, fading) in the later period! To this end, we should correctly understand the ratio of full-price materials, reduce costs and improve efficiency!

The second is to strictly control the quality and proportion of energy and protein raw materials, especially corn raw materials. Corn raw materials are generally added in more than 60% of the total material ratio, so the quality of corn is one of the biggest factors affecting the quality of total material. Obviously, corn is the main force in providing energy, but excessive addition of more energy required by the body will naturally lead to over-fattening of the body, which is also the source of fatty liver problems. Therefore, the best way is to weigh the corn ingredients so that the quantity is accurate. It is true that corn mold is also the culprit of liver problems, especially aflatoxin is the most likely to cause liver problems, so a large number of corn cob mold is also the main source of mycotoxins. The liver is laying hens laying performance expression and antigen protein synthesis and detoxification function and other aspects of the comprehensive internal organs, if the mycotoxins exceed the standard, as well as endogenous toxins (excessive intake of nutrients produced toxins and beneficial bacteria metabolites) exceed the standard will lead to liver problems.

In short, the emergence of liver problems is the expression of a comprehensive problem. The emergence of each problem is a comprehensive manifestation of many problems, and finally manifested through the precipitation of time. In order to solve the liver problem, we should strictly control the links from the raw materials (corn, soybean meal, bran, calcium source-refusing to use low-quality shellfish powder), and then the most important accurate nutrition and balanced nutrition, finally to dynamic nutrition, and work hard to accurately calculate and weigh. Then there is the accurate and regular liver health care work in place! Fine management is the biggest weight to improve economic efficiency! Scientific chicken is to do a good job in every detail, so that the laying hens high and stable yield, long-term stable and sustainable development of the only way!
