Effect of manganese on chicken flocks

Manganese is mainly found in the blood and liver in chickens, and is extremely low in other organs and in skin, muscles and bones. It is a component of arginase and an activator of intestinal peptidase, carboxylase, ATPase, etc., involved in the metabolism of carbohydrates, proteins and fats. In addition, manganese is also required for the development of chicken bone. In the absence of manganese, the chicks suffer from short bones or Chen "sickness", that is, the leg bones are slightly thick and short, and the joints of the tibia and the tibia are swollen, so that the gastrocnemius tendon slips out from the condyle, and the young birds cannot stand; the chickens lay eggs. The amount is significantly reduced, the eggshell is thinned, and the hatching rate of the eggs is reduced. 8Rq China Feed Industry Information Network - based on feed, serving animal husbandry

Under normal circumstances, chickens should contain 55 mg of manganese per kilogram of food. Common feeds for chickens such as grains, oil cakes, bran, fish meal, etc., vary greatly in manganese content due to different origins. In general, the content of manganese in the compound feed can not meet the needs of the chicken. Usually, 242 g of manganese sulfate (including among the trace element additives, equivalent to 55 g of pure manganese) is added per ton of the diet. Meet the needs of the chicken, all the manganese in the feed as a safety margin. Chickens have strong tolerance to excess manganese. According to the test, adult chicken diet contains 0.1% pure manganese, which is nearly 20 times higher than the required amount. There is no obvious poisoning in a short period of time. Therefore, manganese poisoning rarely occurs in chickens, but excessive manganese in the diet has a certain destructive effect on vitamin A. 8Rq China Feed Industry Information Network - based on feed, serving animal husbandry
