围产期疾病的发病率及其对产犊到第一次服务间隔，产犊到受孕间隔和每次受孕的平均服务次数的影响记录在5个弗里斯兰荷斯坦牛群在英国。产乳热、产乳热后子宫内膜炎、胎膜滞留、胎膜滞留后子宫内膜炎、子宫内膜炎或卵巢囊肿的发病率分别为7.5%、1.4%、1.3%、3.3%、10.1%和6.7%，（P <0.05），与同窝配种相比，延长了产犊至受孕间隔（分别为13、66、25、51、31和64天）。产犊到第一次服务间隔和每次受孕的服务也受到不利影响。尽管进行了治疗，但产奶热、子宫内膜炎和卵巢囊肿对生育能力有相当大的影响。显然需要改进治疗和/或预防方法。
The incidence of periparturient diseases and their effects on the calving to first service interval, the calving to conception interval and the mean number of services per conception were recorded in five Friesian-Holstein herds in the United Kingdom. The incidence rates of milk fever, milk fever followed by endometritis, retained fetal membranes, endometritis after retained fetal membranes, endometritis, or ovarian cysts, were 7.5, 1.4, 1.3, 3.3, 10.1 and 6.7 per cent, respectively, and the affected cows had significantly (P less than 0.05) extended calving to conception intervals (13, 66, 25, 51, 31 and 64 days, respectively) compared with herd-mates. Calving to first service intervals and services per conception were also adversely affected. In spite of treatment, milk fever, endometritis and ovarian cysts had a considerable impact on fertility. Improved methods of treatment and, or, prevention are clearly required.
