Plasma creatinine, urea, bilirubin, glucose, cholesterol, calcium, magnesium, sodium, potassium, inorganic phosphorus and total serum proteins were analyzed in kids of Dwarf and Danish Landrace breeds from birth to 12 months of age. The purpose was to determine the reference ranges, age profiles and the influence of other factors. Comparisons between parametric (mean +/- standard deviation) and the corresponding nonparametric (5th and 95th percentile, median) values were calculated for each parameter, the results of which indicated no apparent differences. The levels were very much dependent on age. Creatinine, urea and total serum protein levels increased gradually with age. Glucose and cholesterol levels were high at birth and then decreased with age. The electrolyte concentrations were maintained within narrow limits. Significant differences were observed between kids of different ages (within the breeds), breeds (within similar age) and herds (within the same age and breed). Differences between female and male Landrace kids of the same ages were observed in plasma urea, creatinine, glucose and total serum proteins. It is concluded that age has a major influence on the clinical chemical reference values in young goats, followed by herd and breed, but the influence of sex was small and is negligible in most parameters.
对侏儒山羊和丹麦长白山羊品种的幼崽从出生到12月龄的血浆肌酐、尿素、胆红素、葡萄糖、胆固醇、钙、镁、钠、钾、无机磷和血清总蛋白进行了分析。目的是确定参考范围、年龄分布以及其他因素的影响。对每个参数计算了参数值（平均值±标准差）与相应的非参数值（第5和第95百分位数、中位数）之间的比较，结果表明无明显差异。这些水平在很大程度上取决于年龄。肌酐、尿素和血清总蛋白水平随年龄逐渐升高。葡萄糖和胆固醇水平在出生时较高，然后随年龄降低。电解质浓度维持在狭窄范围内。在不同年龄（品种内）、品种（相似年龄内）和畜群（相同年龄和品种内）的幼崽之间观察到显著差异。在相同年龄的丹麦长白山羊幼崽中，血浆尿素、肌酐、葡萄糖和血清总蛋白在雌性和雄性之间存在差异。得出的结论是，年龄对幼山羊临床化学参考值有主要影响，其次是畜群和品种，但性别影响较小，在大多数参数中可忽略不计。
