Abstract：
The present study aimed to determine the effects of dietary Lonicera flos and Sucutellaria baicalensis mixed extract (LSE) supplementation during the late-pregnancy period on the reproductive performance, umbilical cord blood hematological parameters, umbilical cord serum biochemical parameters, immune indices, hormone levels, colostrum ingredients, and immunoglobulin contents of sows. A total of 40 hybrid pregnant sows were randomly assigned to the control group (CON; sows fed a basal diet) and LSE group (LSE; sows fed a basal diet supplemented with 500 g/t PE). The results indicated that dietary LSE supplementation significantly increased (p < 0.05) the number of alive and healthy piglets and the litter weight at birth, and significantly increased (p < 0.05) the platelet counts in umbilical cord blood. Dietary LSE supplementation significantly increased (p < 0.05) the levels of prolactin (PRL) and growth hormone (GH), and the content of interleukin 2 (IL-2) in umbilical cord serum. Moreover, immunoglobulin A (IgA) and immunoglobulin M (IgM) in the colostrum were increased with PE supplementation (p < 0.05). In conclusion, dietary LSE supplementation in late-pregnancy sows could improve reproductive performance and colostrum quality, and could also regulate the levels of reproductive hormone in umbilical cord serum.
摘要：
本研究旨在确定妊娠后期饲粮中添加金银花和黄芩混合提取物（LSE）对繁殖性能的影响。脐带血血液学参数，脐带血生化指标,免疫指数，激素水平,初乳成分,母猪的免疫球蛋白含量。将总共40头杂交妊娠母猪随机分为对照组（CON；饲喂基础日粮的母猪）和LSE组（LSE；饲喂补充500g/tPE的基础日粮的母猪）。结果表明，饲粮添加LSE显著增加了(p<0.05)存活和健康仔猪的数量和出生时的产仔数。脐血血小板计数显著升高(p<0.05)。日粮补充LSE显着增加（p<0.05）催乳素（PRL）和生长激素（GH）的水平，和脐带血清中白细胞介素2（IL-2）的含量。此外，补充PE后，初乳中的免疫球蛋白A（IgA）和免疫球蛋白M（IgM）增加（p<0.05）。总之,妊娠晚期母猪饲粮补充LSE可以提高母猪的繁殖性能和初乳质量,还可以调节脐带血中生殖激素的水平。
