Magnesium in layer diets

摘要

Magnesium is an important mineral in poultry nutrition and plays a key roie in various bodiiy functions. it may seem surprising, but there is as much magnesium in the shell of an egg as there is phosphorus. The levels of phosphorus, magnesium and other key elements in the egg shell are shown in Table 1). Despite this, considerably more research effort has gone into aspects of phosphorus nutrition than into those of magnesium. There are some poultry nutritionists who believe that there is an interaction between calcium, phosphorus and magnesium that plays a role in the feeding of chickens.
