【摘要】：为探究二元杂交猪和太湖猪在不同妊娠期血液生化指标和激素的变化,试验采集妊娠前(0 d)和妊娠30、60、90、110 d的大×长二元杂交猪,妊娠5、35、110 d太湖猪的耳静脉血液进行ELISA测定。结果表明:大×长二元杂交母猪在妊娠60、90 d的尿素氮(BUN)、葡萄糖(GLU)、催乳素(PRL)、孕酮(PROG)、雌二醇(E_2)和前列腺素(PGF_(2α))显著高于妊娠前(P0.05);太湖母猪妊娠35、110 d的GLU显著低于妊娠5 d(P0.05);35 d的甘油三酯(TG)、E_2、PROG显著高于110 d(P0.05),妊娠35、110 d的丙氨酸转氨酶(ALT)显著高于妊娠5 d(P0.05)。大×长二元杂交猪和太湖猪的血液生化指标和激素含量随妊娠期的发展所呈现出的变化趋势基本一致,表明它们既有种属一致性,又有品种差异性。
[Abstract]:In order to investigate the changes of biochemical indexes and hormones in blood of two hybrid pigs and Taihu pig during different gestational period, ELISA was measured in the aural vein blood of the large 脳 long binary crossbred pigs, which were collected on the first day of pregnancy (0 d before pregnancy) and 30 060,90110 d of gestation, and 535110 d after pregnancy. The results showed that the levels of urea nitrogen bun, glucose gluconium, prolactin, progesterone, estradiol PGF2 伪 and prostaglandin PGF2 伪 in large 脳 long binary crossbred sows on day 6090 of gestation were significantly higher than those of prepregnancy P0.05.The GLU of Taihu sows on day 35110 of gestation was significantly lower than that of pregnancy 5. The level of triglyceride (TGG) at 35 days after gestation was significantly higher than that at 110d (P 0.05), and the alanine aminotransferase (alt) at 35110 d gestation was significantly higher than that on the 5th day of gestation (P 0.05). The variation trend of blood biochemical index and hormone content of big 脳 long binary crossbred pig and Taihu pig with the development of pregnancy is basically the same, which indicates that they have both species consistency and variety difference.
