| 英文描述 | Birds, having a substantially higher requirement for manganese than mammals, are much more susceptible to manganese deficiency. A supplement is commonly added to feed, since the amount of manganese in the common ingredients of poultry diets is often inadequate. Manganese-deficient chicks and turkey poults develop perosis characterized by gross enlargement and malformation of the tibiometatarsal joint with subsequent slippage of the gastrocnemius tendon from its condyles, pulling the leg laterally or medially. Embryos show gross skeletal defects including micromelia; domed, globular heads; and shortening of the lower mandible. Viable chicks may suffer tetanic spasms and head retraction. |
