Diagnosis of twin pregnancy is possible by ultrasound at the time of early pregnancy examination [28\u201334 days after artificial insemination (AI)]. Pregnancy proteins are also well-known indicators of gestation. The risk of pregnancy loss during the first trimester of gestation for cows carrying twins is three to nine times higher than for cows carrying singletons. Pregnancy-specific protein B (PSPB) is a good indicator not only of pregnancy but also of pregnancy loss. The aims of this study were (a) to collect calving data in some Hungarian Holstein-Friesian herds (n = 7,300) to compare PSPB serum concentrations (measured 29\u201335 days post insemination) in twin- and singleton-calving cows (Trial 1), and (b) to check the predictive value of PSPB serum concentration for twin pregnancy and pregnancy loss in high-producing Spanish Holstein-Friesian cows (n = 98; Trial 2). Our results showed almost 7% twin calving rate. Although hormonal treatments are commonly believed to be major causes of twin pregnancies, our data do not support this hypothesis. The only exception is the single PGF injection, which significantly increased twin calving. No effect of milk production on the risk of twin pregnancy was found, and twin pregnancy increased with parity. The AI bull, the bull\u2019s sire, the bull\u2019s grandfather and the cow\u2019s father also affected twin calving (P \u2264 0.02). We found much higher frequency of twin calving in cows diagnosed pregnant with higher than 3 ng\/ml serum PSPB concentrations at 29\u201335 days after insemination. In Trial 2, non-significant but well-marked differences were found in PSPB serum concentration between singleton- and twin-pregnant cow samples (2.1 and 2.9 ng\/ml) at different bleeding times. Probably the small size of the study population and the effects of milk production on PSPB values may explain this lack of significance.<\/jats:p>","DOI":"10.1556\/004.2018.040","type":"journal-article","created":{"date-parts":[[2018,10,5]],"date-time":"2018-10-05T12:17:56Z","timestamp":1538741876000},"page":"451-461","update-policy":"http:\/\/dx.doi.org\/10.1556\/policypage.crossmark.crossref.2","source":"Crossref","is-referenced-by-count":6,"title":["Is twin pregnancy, calving and pregnancy loss predictable by serum pregnancy-specific protein b (pspb) concentration 28\u201335 days after ai in dairy cows?"],"prefix":"10.1556","volume":"66","author":[{"given":"Zolt\u00e1n","family":"Szel\u00e9nyi","sequence":"first","affiliation":[{"name":"Department and Clinic of Farm Animal Medicine, University of Veterinary Medicine, \u00dcll\u0151, D\u00f3ra major, Hungary"},{"name":"MTA-SZIE Large Animal Clinical Research Group, \u00dcll\u0151, D\u00f3ra major, Hungary"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Orsolya Gabriella","family":"Balogh","sequence":"additional","affiliation":[{"name":"National Agricultural Research and Innovation Center, Research Institute for Animal Breeding, Nutrition and Meat Science, Geszteny\u00e9s u. 1, H-2053 Herceghalom, Hungary"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Fernando","family":"Lopez-Gatius","sequence":"additional","affiliation":[{"name":"Universitat de Lleida, and Agrotecnio Center, Lleida, Spain"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Irina","family":"Garcia-Ispierto","sequence":"additional","affiliation":[{"name":"Universitat de Lleida, and Agrotecnio Center, Lleida, Spain"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Eszter","family":"Krik\u00f3","sequence":"additional","affiliation":[{"name":"Centre for Bioinformatics, University of Veterinary Medicine, Budapest, Hungary"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Gy\u00f6rgy","family":"G\u00e1bor","sequence":"additional","affiliation":[{"name":"National Agricultural Research and Innovation Center, Research Institute for Animal Breeding, Nutrition and Meat Science, Geszteny\u00e9s u. 1, H-2053 Herceghalom, Hungary"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"425","reference":[{"key":"rf1","doi-asserted-by":"publisher","DOI":"10.1016\/j.theriogenology.2012.05.014"},{"key":"rf2","doi-asserted-by":"publisher","DOI":"10.1016\/j.theriogenology.2012.07.027"},{"key":"rf3","doi-asserted-by":"publisher","DOI":"10.2527\/jas1978.464950x"},{"key":"rf4","first-page":"526","volume":"129","author":"Eddy R.
