中文摘要:

      【目的】本试验旨在研究注射维生素ADE对母牛繁殖性能的影响。【方法】试验选取饲养管理条件相同、不同胎次、怀孕7个月的西门塔尔母牛共三批次 ，每批次试验组30头、对照组20头，三批次共计150头。对照组母牛严格执行保健护理程序，在产后14天、28天、42天各肌注PGF2α4 ml，从第42天注射PGF2α的次日起，每天全天候视频监控发情情况，连续观察15 d。试验组母牛产前60 d、产前30 d、产后2 h内各肌肉分点注射维生素ADE注射液 10 ml，其余程序均与对照组相同，从第42天肌肉注射PGF2α的次日起，每天全天候视频监控发情情况，连续观察15 d。【结果】结果显示，试验组的胎衣不下的发病率显著低于对照组（P <0.05），产后瘫痪、子宫内膜炎的发病率极显著低于对照组（P <0.01），试验组的发情率极显著高于对照组（P＜0.01），试验组的情期受胎率极显著高于对照组（P＜0.01）。【结论】注射维生素ADE不仅能显著减少母牛产后胎衣不下、产后瘫痪、子宫内膜炎的发病率；还能显著提高产后母牛的发情率和情期受胎率。

英文摘要:

      【purpose】The aim of this experiment is to investigate the effect of vitamin ADE injection on reproductive performance of cows.【method】Three batches of Simmental cows with the same feeding and management conditions, different parity, and 7 months of pregnancy were selected for investigation and statistics in the experiment,Each batch consists of 30 rats in the experimental group and 20 rats in the control group, with a total of 150 rats in the three batches.The control group cows strictly followed the health care procedures,intramuscular injection of 1ml of PGF2α on days 14, 28, and 42 postpartum,starting from the day after the injection of PGF2α on the 42nd day,video surveillance of estrus was conducted 24/7 every day for 15 consecutive days.The experimental group cows were injected with 10 ml of vitamin ADE injection into their muscles at different points within 60 days before delivery, 30 days before delivery, and 2 hours after delivery. The rest of the procedures were the same as those in the control group. Starting from the day after the muscle injection of PGF2α on the 42nd day, the estrus status was monitored by video surveillance 24/7 every day for 15 consecutive days.【result】The results showed that the incidence rate of retained placenta in the test group was significantly lower than that in the control group(P<0.05).The incidence rate of postpartum paralysis and endometritis was significantly lower than that of the control group(P<0.01).The estrus rate of the experimental group was significantly higher than that of the control group (P<0.01).The conception rate during estrus in the experimental group was significantly higher than that in the control group (P<0.01).【conclusion】The injection of vitamin ADE can not only significantly reduce the incidence rate of postpartum placenta retention, postpartum paralysis and endometritis in cows; It can significantly improve the estrus rate and conception rate of postpartum cows.
