Postpartum clinicopathological and reproductive performance assessment and haptoglobin measurement of dairy cattle with retained fetal membrane

Issue Date

Abstract

Cattle with retained fetal membrane (RFM) interrupt optimal dairy productivity including reproductive performance. In this 28-mo duration experimental study, several clinical tests (observation of morbid clinical signs, rectal temperature, vaginal discharge scoring, and blood inflammatory marker measurements) were completed in 19 cattle with RFM including 8 cattle with normally expelled fetal membrane. Twelve out of 19 cattle showed morbid clinical signs at 2.2 ± 1.3 days postpartum (dpp) and pyrexia at 2.3 ± 1.7 dpp. All cattle with RFM had vaginal discharge scores of 1-3 (4-point scale) that steadily persisted for 2-8 wk postpartum. Lower conception rates were noted in cattle with RFM than in cattle with no RFM (64% vs. 100%). Blood haptoglobin (Hp) levels of cattle with RFM and with morbid clinical signs were consistently elevated from 1-10 d (all P < 0.01). The Hp of test cattle for 3 d correlated with the ‘days open’ (Rs = 0.47). These findings have in effect validated the value of using Hp in assessing cattle with RFM. In addition to using Hp, regular clinical and laboratory tests as described herein should be integrated in the management of cattle with RFM.
