摘要

High performing layers face challenges that affect gut health and egg shell quality. Mintrex chelated trace minerals Zinc, Copper and Manganese help develop key tissues which benefit the overall health and productivity of laying hens.The impact of genetic selection on the performance of layer hens has been dramatic. Hens reared in colonies now produce up to 350 eggs over an 80 week period. Free range hens face additional challenges that affect gut health and shell quality. This requires nutritionists toprovide a balance of key nutrients to sustain the health and welfare of the bird and to ensure the quality of the product. As with other production systems, the requirements for the major nutrient groups are well established, and more recently, the focushas shifted to evaluate the importance of key micronutrients in maintaining metabolic balance. For example, Zinc (Zn), Copper (Cu) and Manganese (Mn) areknown to have specific roles in avian metabolism, all of which are relevant to the laying hen (Table J). Trace mineral supply within the diet has traditionally been achieved through the use of inorganic trace minerals (ITMs). These are the sulphate or oxide salts of the mineral and, commercially, are often included in the diet at levels in excess of those recommended by national bodies such as the National Research Council (NRC). This reflects the uncertainty of the uptake of mineral elements from ITM sources and the desire to ensure an adequate supply to the tissues of the bird.
