A. Functions and roles of the liver
(1) Immune function: the liver is an important part of the body’s immune system, through the reticuloendothelial cells phagocytosis, isolation and elimination of invasive and endogenous pathogenic bacteria and antigens, to maintain the health of the immune system.
(2) Metabolic function, the liver is involved in the synthesis and metabolism of nutrients such as sugar, fat and protein.
(3) Interpretation function, the liver is the largest interpretation organ in laying hens, which can rapidly decompose and oxidize harmful substances and foreign toxins produced during the metabolic process of the organism, decompose the products, and protect laying hens from readings.
(4) Digestive function, the liver makes and secretes bile, which is transported to the gallbladder through the bile ducts to help accelerate the digestion and absorption of fat.
(5) Coagulation function, most of the coagulation factors are manufactured by the liver, which plays an important role in regulating the dynamic balance of coagulation-anticoagulation in the body.
B. the physiological functions of the kidneys
(1) generate urine, is the main way to excrete body metabolic waste toxins, discharge of urine, laying hens can effectively remove body metabolites and excess water, to maintain the stability of the body’s internal environment.
(2) maintenance of body fluids and acid-base balance, regulating the composition and amount of urine in laying hens, ensuring that the water and electrolytes in the body of laying hens are at a suitable level, thus maintaining the balance of body fluids.
(3) Endocrine function, the kidneys can secrete vasoactive substances (such as renin and kinin) to regulate blood pressure, as well as to promote the production of erythropoietin, promote Bone marrow hematopoiesis, which has a direct impact on the productivity of laying hens.
C.What is the harm of liver function decline?
(1) Decrease in immunity, poor resistance to disease and stress, easy to develop disease, high mortality rate.
(2) The reproductive function of laying hens decreases, the egg-laying peak lasts for a short time or there is no egg-laying peak or the egg-laying rate decreases.
(3) The growth of broilers is hindered, and they become thin and lifeless, with an increase in the feed-to-meat ratio.
(4) Loss of appetite, decreased feed intake, or sometimes good and sometimes bad.
(5) Metabolic disorders, lusterless feathers, depressed spirit.
D. the performance of liver function decline in laying hens
Crown whitening and thinning;
Increase in broken eggs and thinning of eggshells;
Egg production rate decline;
Fatty liver, mold poisoning, etc. leading to the increase in the rate of dead eggs
E. How to treat and prevent liver and kidney function decline?
Treatment:
1、Add liver and kidney health and choline chloride to feed for 3-5 days.
2、Supplement special multi-vitamin for egg birds.
3、Adjust the feed formula or reduce the energy of feed, pay attention to the addition of corn should not be too high.
4、Don’t use moldy feed for chickens, and add de-molding agent in feed for a long time in summer.
Prevention:
1, from the introduction of breeding, the introduction of high-quality chickens, to avoid the transmission of poverty and other disease factors.
2, carry out the field environmental control, reduce the total number of bacteria per unit area of the field, the total number of viruses, minimize, reduce or avoid all kinds of stress.
3、Provide high-quality, balanced diets, ensure no mold, and vitamins, trace elements sufficient and reasonable; add less and more often to ensure nutrition, reduce waste, avoid mold.
4、In the process of epidemic prevention, we should change the needles frequently to avoid man-made disease transmission.
5、According to the physiological characteristics of laying hens at various stages, use some anti-stress, liver and kidney drugs regularly for prevention.
