Abstract:In order to determine the contents of main mineral elements in health sand,we collected 11 kinds of health sand products from 11 regions in 6 provinces.The effects of pretreatment methods including wet digestion,dry digestion and acid dissolution on the determination of Ca and P in health sand samples were compared,and the appropriate method were selected.The contents of Ca,P,Fe,Cu,Zn and Mn in the samples were determined by GB/T 6436-2018,GB/T 6437-2018 and GB/T 13885-2017,respectively.The results showed that the value of calcium content in No.3 sample by dry method was 3.16%higher than the result of wet digestion(P<0.05),while the calcium values of No.5 sample by the methods of dry and acid dissolution were 0.87%,2.16%lower,respectively,compared with the result of wet digestion(P<0.05).And the method of acid dissolution was most suitable for the pretreatment of health sand products for pigeons.The contents of Ca in health sand samples from most regions were high.And the highest content of Ca was 29.4%.The P content was generally severely low.The P content of the 8 samples was below 0.05%.And the values of the 8 samples were greatly lower than the results of the remaining 3 ones.The ratios of calcium to phosphorus were more than 100,and the highest ratio reached 792,which reflectd the serious lack of P in health sand.The contents of Fe,Cu,Zn and Mn in the samples ranged from 3387~22184.8,3.8~112.5,7.46~865.5 mg/kg and 58.8~1401 mg/kg.It concluded that the contents of mineral elements in health sand were quite different,because there were no unified nutrition standards for pigeons till now.And the nutritional quality of healthy sand for pigeons needed to be studied further.
Keywords:health sand  mineral element  pretreatment  Ca  P
