| prevalence and reproductive effects of ureaplasma diversum in beef replacement heifers and the relationship to blood urea nitrogen level. | a systematic sample of replacement heifers from 5 herds underwent prebreeding vaginal swab cultures for ureaplasma diversum. heifers from three of the herds were subsequently sampled at pregnancy examination. sampled heifers were given a vaginal lesion score (vls), reproductive tract score (rts) and body condition score (bcs), and peripheral blood was collected for serum blood urea nitrogen (bun) estimation. culture results revealed an overall prevalence of ureaplasma diversum of 51% (87/171) at ... | 2000 | 11051323 |
