Calcium, phosphorus and magnesium levels and alkaline phosphatase activity in the blood of one-day-old ostriches

Considering that clinical conditions, feeding and holding conditions as well as microflora and microfauna vary from one country to another, standard values of individual ostrich health status indicators should be established on a country basis.. This particulary applies to ostriches at their earliest stage when they are extremely sensitive to stress induced by temperature fluctuations, initial feeding, change of feeding regime, imbalaced ration composition, holding pen overpopulation, etc. Potential concequences include death or abnormal growth and development from the very begining. calcium, phosphorus and magnesium metabolism disorder is one of the recognized causes of skeletal development problems. The research was carried out on 10 healthy, one-day-old, unsexed ostriches of the variety Struthio camelus domesticus. The results have shown that calcium, phosphorus and magnesium levels were 2, 33 mmol/L, 4, 56 mmol/L and 0, 76 mmol/L respectively, and ALP activity was 251, 63 U/L.These results, although obtained on a relatively small number of birds, represent a valuable contribution to ostrich physiology because they may serve as reference values when investigating calcium, phosphorus and magnesium metabolism and/or abnormalities in skeletal development in these animals.
