There is no complete early warning system for the occurrence of ovarian quiescence in clinical cows. This test provides early warning indicators for clinical prediction of ovary cessation in dairy cows. This experiment selected blood samples of dairy cows from 60 to 90 days postpartum in the inactive ovaries group and control group. Differential proteins were selected on the basis of proteomics, three energy indexes: AST, Glu, NEFA. Four reproductive hormones: E2, P4, FSH, LH, and four differentially expressed proteins: IGFBP-2, AHSG, APO-A4, and RBP-4. Key enzyme activities: ALDOB, LDHB, ITIH3, GPX3, SPAM1, PKM2. The ELISA test kit was used to detect the content and activity of the above markers in the test bovine serum. Through correlation analysis, binary logistic regression modeling and ROC analysis, a single indicator early warning technique for APOA4 and ITIH3 was established. The early warning values were APOA4 > 28.825 μg/L and ITIH3 > 195.07 ng/L. A multi-index early warning system based on potential biomarkers of APOA4 + ITIH3 and APOA4 + ITIH3 + E2 was established. The former had an early warning value of: APOA4 > 19.55 μg/I;ITIH3 > 191.14 ng/L;the latter has an early warning value: APOA4 > 47.56 μg/L, ITIH4 > 187.80 ng/L, E2 < 69.63 ng/L.展开更多
为了评价藿芪灌注液治疗奶牛卵巢静止和持久黄体的临床效果,将确诊为患持久黄体和卵巢静止的病牛各40头随机分为4组,分别为藿芪灌注液高、中(推荐剂量)、低剂量治疗组和对照药物治疗组,每组10头。试验组每头牛每次分别按150 m L、100 m ...为了评价藿芪灌注液治疗奶牛卵巢静止和持久黄体的临床效果,将确诊为患持久黄体和卵巢静止的病牛各40头随机分为4组,分别为藿芪灌注液高、中(推荐剂量)、低剂量治疗组和对照药物治疗组,每组10头。试验组每头牛每次分别按150 m L、100 m L和50 m L的剂量子宫灌注,隔日1次,4次为1个疗程;对照药物治疗组为促孕灌注液,每次100 m L,隔日1次,4次为1个疗程。试验结果表明,用藿芪灌注液治疗奶牛持久黄体的高、中、低剂量组的治愈率分别为80%、70%和50%,总有效率分别为90%、90%和60%;对照组治愈率80%,总有效率90%,藿芪灌注液高剂量组、中剂量组与对照组的治愈率和总有效率均显著高于低剂量组(P<0.05),高剂量组与中剂量组之间无显著性差异(P>0.05);高、中剂量组与对照组之间无显著性差异(P>0.05)。用藿芪灌注液治疗奶牛卵巢静止高、中、低剂量组的治愈率分别为90%、80%和60%,总有效率分别为100%、100%和70%;对照组治愈率80%,总有效率90%,高剂量组、中剂量组和对照组的治愈率和总有效率均显著高于低剂量组(P<0.05),高剂量组与中剂量组之间无显著性差异(P>0.05),高、中剂量组与对照组之间无显著性差异(P>0.05)。展开更多
