【摘要】：研究牛至精油对奶牛产后子宫感染预防、子宫复旧的作用及对产后发情的影响,为奶牛产后护理和合理安排配种提供依据。将新产犊后的荷斯坦奶牛分为试验A组(子宫投放牛至精油)和B组(对照组),测定其部分繁殖及血液生理指标。结果显示:A组奶牛的宫颈黏液、直肠检查评分均显著高于B组,血液中白细胞和中性粒细胞数显著低于B组,其产后15和30d时血液白细胞数、中性粒细胞数、淋巴细胞数、红细胞数和血红蛋白浓度均显著低于产后0d的水平(P0.05)。结果表明:牛至精油可杀灭一定数量的病原菌并可预防持续感染,有利于奶牛产后子宫复旧及提早发情,建议在奶牛生产中酌量使用。
[Abstract]:To study the effect of the essential oil of oregano on the prevention of postpartum uterine infection, the restoration of uterus and the influence of postpartum estrus on postpartum oestrus of dairy cows, which provides the basis for postpartum nursing and reasonable arrangement of breeding. The Holstein cows after calving were divided into two groups: group A (uterus with essential oil) and group B (control group). The results showed that the cervical mucus and rectum examination scores in group A were significantly higher than those in group B, and the number of white blood cells and neutrophils in group B was significantly lower than that in group B. the number of white blood cells, neutrophils and lymphocytes in group B was significantly lower than that in group B at 15 and 30 days postpartum. Erythrocyte count and hemoglobin concentration were significantly lower than those of 0 d postpartum (P0.05). The results showed that the essential oil of oregano could kill a certain number of pathogenic bacteria and prevent continuous infection, which was beneficial to the recovery of uterus after delivery and early estrus.
