摘 要：
为了探讨青海环湖地区放牧绵羊骨营养状况,采用二甲氨基苯甲醛比色法、孔雀绿—钼酸比色法、MTB比色法和磷酸苯二钠法,对青海环湖地区4个县55只2～3岁放牧绵羊血清羟脯氨酸、钙和磷含量以及碱性磷酸酶进行了测定。结果表明,被检放牧绵羊的血清游离羟脯氨酸含量为(15.359±1.655)μmol/L,血清碱性磷酸酶活性为(2.797±0.741)nmol/(L·s),血清钙、磷含量分别为(2.443±0.291)mmol/L和(1.210±0.390)mmol/L,血清无机磷明显低于正常值(P<0.05)。结论说明,被检的55只放牧绵羊处于低磷的营养水平。

摘 要：
The purpose was to discuss the bone nutritional condition of grazing sheep around Qinghai Lake. The contents of hydroxyproline,calcium and phosphorus and activities of alkaline phosphatase in serum of 55 2～3-year old grazing sheep from 4 counties in the region around Qinghai Lake were determined by dimethylaminobenzaldehyde colorimetry,malachite green-molybdic acid colorimetry,MTB colorimetry and disodium phenyl phosphate method. The results showed that the contents of hydroxyproline in serum of determined grazing sheep were (15.359 ± 1.655) μmol/L,their activities of alkaline phosphatase in serum were (2.797 ± 0.741) nmol/(L·s),their contents of calcium and phosphorus in serum were (2.443 ± 0.291) and (1.210 ± 0.390)mmol/L resp. and their contents of inorganic phosphorus in serum were significantly lower than normal value (P<0.05). The 55 determined grazing sheep were at the nutrition level of low phosphorus.
