【摘要】 为了探讨母猪在怀孕后期和哺乳期的骨骼代谢状况，本文作者于2005年在广东省某规模化养猪场，选取临床健康、无骨骼疾病、不同胎次的怀孕母猪10头，分别在产前30d、20d、10d、产仔当天、产后5d、10d、20d、30d，清晨空腹耳静脉采取血液10ml，迅速分离血清，用化学分析方法，测定血清中的碱性磷酸酶(含热保留试验和保留率)、羟脯氨酸、谷氨酸蛋白(骨钙素)和钙、磷的含量。结果发现：母猪产前碱性磷酸酶从主要来源于肝脏逐渐变为主要来源于骨骼，产后又逐渐从主要来源于骨骼变为来源于肝脏；血清钙在产前10d开始逐渐下降，产后10d降至最低，产后20d开始逐渐回升；血清磷、羟脯氨酸和谷氨酸蛋白在整个围产期变化不明显。表明母猪在整个围产期，骨骼代谢是相对比较稳定的。说明所选用的不同期的全价配合饲料基本上能够满足母猪在不同生理时期的需要。更多还原

【Abstract】 To investigate bone metabolism of sow during late-pregnancy and lactation, in2005, 10 sows with clinic health, varied parity and without bone disease were chosenfor experiments in a scaled pig farms in Guangdong province. On day 30,20,10,0before delivery and day 5, 10, 20, 30 after delivery separately, 10 mL blood wasdrawn via auricular vein for each sow in the morning without feeding, and serum wasisolated for chemical analysis. Serum alkaline phosphatase, hydroxyproline, glutamateprotein (osteocalcin), calcium and phosphor were determinated. The results showalkaline phosphatase originates mainly from liver to mainly from bone gradually insow befroe delivery and reversely in sow after delivery. Serum calcium decreasesgradually on day 10 before delivery, to the lowest level on day 10 after delivery, andincreases gradually on day 20 after delivery. The change of serum phosphor,hydroxyproline and glutamate protein was not significant in the whole perinatalperiod. It indicates that the bone metabolism of sow is stable relatively in the wholeperinatal period, and the complete formula feeds used in different stages can meet theneeds of sow in different physilolgical period basically更多还原
