摘　　要：本试验旨在研究日粮中添加燕麦青干草粉对互助八眉二元母猪血液生化、激素指标的影响。选取40头体况和胎次相近的互助八眉二元母猪作为试验动物,随机分为对照组、高纤维组、中纤维组、低纤维组(妊娠前期饲粮粗纤维水平分别为13.96%、11.02%、7.83%和4.33%,妊娠中期饲粮粗纤维水平分别为11.93%、9.26%、6.38%和4.33%)。结果表明:①给母猪饲喂添加适宜比例的燕麦青干草粉,降低了尿素氮(P<0.05)、低密度脂蛋白胆固醇(P<0.01)、总胆固醇(P<0.01)、CK浓度(妊娠20d P<0.05,妊娠80 d P<0.01),增加了血糖浓度(P<0.05);②给母猪饲喂添加适宜比例的燕麦青干草粉粉,降低了皮质醇浓度(P<0.05),增加了泌乳素浓度(P<0.05)。综合分析认为,中纤维组母猪日粮(妊娠前期11.02%、妊娠中期9.26%)对血液生化指标和激素指标的影响最为显著。This experiment was to study the diet adding oat hays on serum biochemical and hormone on Huzhu Barnei two -breed cross sows. Forty sows, with similar body condition and breeding time, were randomly divided into control group, high fiber group, middle fiber group and low fiber group（the dietary fiber levels in early pregnancy were 13.95 % ,11.02 % ,7.83 % ,4.33 %, respectively, and 11.93 % ,9. 26 % ,6.38 % ,4.33 % in middle pregnancy）. The results showed that： （i） Oat hay adding a suitable proportion to swine induced urea nitrogen （ P 〈 0.05 ）, low density lipoprotein cholesterol（ P 〈 0.01 ）, total cholesterol（ P 〈 0.01 ）, creafine kinase （ pregnancy 20 d P 〈 0. 05, pregnancy 80 d P 〈 0.01 ）,increased blood glucouse; （ii） Oat hay adding a suitable proportion to swine induced cortisol （P 〈 0. 05 ）, increased prolactin （ P 〈 0. 05 ）. In conclusion, middle fiber group （ early pregnancy 11.02 %, middle pregnancy 9.26 % ） had the most significant on serum biochemical and hormone in the pregnant swine diet.
