This study included 149\u00a0822 pregnancy diagnoses conducted over 13\u00a0years in Holstein\u2010Friesian cows in Hungarian dairy herds. The following were determined: PPL<\/jats:styled-content> in cows diagnosed pregnant by transrectal ultrasonography 29\u201342\u00a0days after artificial insemination (AI<\/jats:styled-content>; n\u00a0=\u00a011\u00a0457); PPL<\/jats:styled-content> in cows diagnosed pregnant by serum PSPB<\/jats:styled-content> 29\u201335\u00a0days after AI<\/jats:styled-content> (n\u00a0=\u00a0138\u00a0365); and PPL<\/jats:styled-content> and its association with serum progesterone concentrations, PSPB<\/jats:styled-content> and production\/environmental variables. The definition of PPL<\/jats:styled-content> was percentage of cows initially diagnosed pregnant based on ultrasonography or PSPB<\/jats:styled-content>, but not pregnant when examined by transrectal palpation 60 \u201370\u00a0days after AI<\/jats:styled-content>. The PPL<\/jats:styled-content> was lower (p\u00a0<\u00a00.001) in cows following ultrasonographic vs PSPB<\/jats:styled-content> diagnosis of pregnancy at 29\u201335\u00a0days (8.1 vs 19.3%, respectively), but was higher in cows following ultrasonographic pregnancy diagnosis on 29\u201335 vs 36\u201342\u00a0days (8.1 vs 7.1%, respectively, P\u00a0<\u00a00.05). Furthermore, 72.9% of pregnancies with ultrasound\u2010detected morphological abnormalities resulted in pregnancy loss. As a subset of PSPB<\/jats:styled-content> data, a fully quantitative PSPB<\/jats:styled-content> assay was used for 20\u00a0430 samples; PPL<\/jats:styled-content> in cows with a high PSPB<\/jats:styled-content> concentration (>1.1\u00a0ng\/ml) was lowest (15.0%), whereas cows with low concentrations of both PSPB<\/jats:styled-content> and progesterone (0.6\u20131.1 and <2\u00a0ng\/ml, respectively) had the highest PPL<\/jats:styled-content> (76.3%; p\u00a0<\u00a00.0001). Furthermore, PPL<\/jats:styled-content> was higher in cows with advanced parity and with high milk production, when ambient temperatures were high, although body condition score (BCS<\/jats:styled-content>) had no effect on PPL<\/jats:styled-content>. Finally, there were no significant associations between serum PSPB<\/jats:styled-content> and environmental temperatures or number of post\u2010partum uterine treatments.<\/jats:p>","DOI":"10.1111\/rda.12703","type":"journal-article","created":{"date-parts":[[2016,5,21]],"date-time":"2016-05-21T21:46:28Z","timestamp":1463867188000},"page":"467-473","source":"Crossref","is-referenced-by-count":45,"title":["Pregnancy Loss in Dairy Cattle: Relationship of Ultrasound, Blood Pregnancy\u2010Specific Protein B, Progesterone and Production Variables"],"prefix":"10.1111","volume":"51","author":[{"given":"G","family":"G\u00e1bor","sequence":"first","affiliation":[{"name":"National Agricultural Research and Innovation Centre Research Institute for Animal Breeding, Nutrition and Meat Science Herceghalom Hungary"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"JP","family":"Kastelic","sequence":"additional","affiliation":[{"name":"Department of Production Animal Health Faculty of Veterinary Medicine University of Calgary Calgary, Alberta Canada"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Z","family":"Abonyi\u2010T\u00f3th","sequence":"additional","affiliation":[{"name":"Faculty of Veterinary Science Szent Istvan University G\u00f6d\u00f6ll\u0151 Hungary"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"P","family":"G\u00e1bor","sequence":"additional","affiliation":[{"name":"Androvet Kft.
