Analyses were performed in 16 praepubertal and 85 sexually mature gilts of the Bohemian Large White breed. The content of dry matter in the endometrium of praepubertal gilts was 15.511%, on an average, and in sexually mature sows 11.968%, on an average, in the follicular phase, and 14.326% in the luteal phase. The differences are statistically highly significant (P less than 0.01). Considerable differences (mostly highly significant) were found also in the contents of calcium, phosphorus, magnesium, sodium, potassium, and chlorine in the dry matter of endometrium in praepubertal and sexually mature sows; however, these differences were less frequently dependent on individual stages of the sexual cycle. The highest content of calcium (1.112 mg g(-1)), phosphorus (8.357 mg g(-1)), and magnesium (0.720 mg g(-1)) in dry matter was found in gilts in the oestral phase, and the lowest in late or early metestrus (Ca = 0.625 mg g(-1), P = 0.6369 mg g(-1), Mg = 0.498 mg g(-1). Sodium showed the highest values in proestrus (23.359 mg g(-1)), and potassium in oestrus (13.012 mg g(-1)); their lowest values were recorded in late metestrus (Na = = 17.742 mg g(-1)) and in proestrus (K = 10.141 mg g(-1)). The content of these elements in endometrium dry matter was also much lower in praepubertal gilts than in sexually mature sows (with the exception of phosphorus); the difference was always highly significant.
对16头青春期前和85头性成熟的波希米亚大白猪品种后备母猪进行了分析。青春期前后备母猪子宫内膜干物质含量平均为15.511%，性成熟母猪在卵泡期平均为11.968%，在黄体期为14.326%。差异具有高度统计学意义（P小于0.01）。在青春期前和性成熟母猪子宫内膜干物质中钙、磷、镁、钠、钾和氯的含量也发现了显著差异（大多具有高度显著性）；然而，这些差异较少依赖于性周期的各个阶段。在发情期后备母猪的干物质中钙（1.112 mg g(-1)）、磷（8.357 mg g(-1)）和镁（0.720 mg g(-1)）含量最高，在发情后期或发情前期最低（钙 = 0.625 mg g(-1)，磷 = 0.6369 mg g(-1)，镁 = 0.498 mg g(-1)）。钠在发情前期含量最高（23.359 mg g(-1)），钾在发情期含量最高（13.012 mg g(-1)）；它们的最低值分别记录在发情后期（钠 = 17.742 mg g(-1)）和发情前期（钾 = 10.141 mg g(-1)）。青春期前后备母猪子宫内膜干物质中这些元素的含量也远低于性成熟母猪（磷除外）；差异始终具有高度显著性。
