Abstract

Interrelationships among nine periparturient traits and their association with parity were investigated in 8521 calvings of dairy cows examined routinely between 5 to 14 d postpartum. Rates of twins, stillbirth, milk fever, prolapsed uterus, retained placenta, primary metritis, displaced abomasum, ketonuria, and aciduria were 5.8, 6.3, 1.4, 3, 17.8, 36.1, 1.7, 30.4, and 29.5%, respectively. The risk for twins, milk fever, prolapsed uterus, displaced abomasum, ketonuria, and aciduria increased with parity, whereas that for stillbirth and metritis was higher in heifers than in cows. Stillbirth, retained placenta, metritis, displaced abomasum, ketonuria, and aciduria were directly associated with birth of twins; prolapsed uterus and retained placenta with stillbirth; prolapsed uterus, retained placenta, and primary metritis with milk fever; displaced abomasum, ketonuria, and aciduria with retained placenta and with metritis; ketonuria and aciduria with displaced abomasum and aciduria with ketonuria.

摘要

在产后5至14天常规检查的8521头奶牛产犊中，研究了九种围产期性状之间的相互关系及其与胎次的关联。双胞胎、死产、产乳热、子宫脱垂、胎盘滞留、原发性子宫炎、皱胃移位、酮尿症和酸尿症的发生率分别为5.8%、6.3%、1.4%、3%、17.8%、36.1%、1.7%、30.4%和29.5%。双胞胎、产乳热、子宫脱垂、皱胃移位、酮尿症和酸尿症的风险随胎次增加而增加，而死产和子宫炎在初产母牛中的发生率高于经产母牛。死产、胎盘滞留、子宫炎、皱胃移位、酮尿症和酸尿症与双胞胎出生直接相关；子宫脱垂和胎盘滞留与死产相关；子宫脱垂、胎盘滞留和原发性子宫炎与产乳热相关；皱胃移位、酮尿症和酸尿症与胎盘滞留和子宫炎相关；酮尿症和酸尿症与皱胃移位相关，酸尿症与酮尿症相关。
