D-cloprostenol sodium (n = 192; Group A) or dinoprost (n = 187; Group B) was administered between days 35 and 42 post partum. Also, a group of non-treated cows (n = 135; Group C) was included as control. Pedometers were used to detect oestrus, and also secondary oestrous signs and vaginal mucus quality were assessed prior to artificial insemination (AI). When oestrus was not detected for 14 days after PGF<jats:sub>2\u03b1<\/jats:sub>administration, the treatment was repeated, up to a maximum of three times. There were no differences between the study groups in oestrus detection (A = 73.48%, B = 73.01%, C = 79.26%; P = 0.428), good mucus quality (A = 96.45%, B = 91.30%, C = 93.45%; P = 0.203) and the presence of mounting lesions (A = 98.58, B = 94.93%, C = 98.13; P = 0.414). First-service pregnancy rates were 19.78%, 15.64% and 32.03% in Groups A, B and C, respectively (P = 0.003). There were no inter-group differences for the interval from parturition to first AI. However, a significantly shorter interval from parturition to conception (92.17 days, 99.45 days, 118.93 days; P = 0.002) and significantly less services per conception (2.12, 2.18, 2.66; P = 0.003) were observed in Groups A and B in comparison with Group C. The use of PGF<jats:sub>2\u03b1<\/jats:sub>resulted in better fertility in a repetitive, routine postpartum programme, although no differences between Dcloprostenol and dinoprost were detected.<\/jats:p>","DOI":"10.1556\/avet.2014.028","type":"journal-article","created":{"date-parts":[[2014,11,6]],"date-time":"2014-11-06T03:32:12Z","timestamp":1415244732000},"page":"79-88","update-policy":"http:\/\/dx.doi.org\/10.1556\/policypage.crossmark.crossref.1","source":"Crossref","is-referenced-by-count":0,"title":["Oestrus synchronisation in postpartum dairy cows using repetitive prostaglandin doses: Comparison between D-cloprostenol and dinoprost"],"prefix":"10.1556","volume":"63","author":[{"given":"Carlos","family":"P\u00e9rez-Mar\u00edn","sequence":"first","affiliation":[{"name":"1 University of C\u00f3rdoba, Campus de Rabanales Department of Animal Medicine and Surgery Ctra Madrid-C\u00e1diz km 396 14071 C\u00f3rdoba Spain"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Jose","family":"S\u00e1nchez","sequence":"additional","affiliation":[{"name":"1 University of C\u00f3rdoba, Campus de Rabanales Department of Animal Medicine and Surgery Ctra Madrid-C\u00e1diz km 396 14071 C\u00f3rdoba Spain"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Guillermo","family":"Vizuete","sequence":"additional","affiliation":[{"name":"1 University of C\u00f3rdoba, Campus de Rabanales Department of Animal Medicine and Surgery Ctra Madrid-C\u00e1diz km 396 14071 C\u00f3rdoba Spain"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Luis","family":"Quintela","sequence":"additional","affiliation":[{"name":"2 University of Santiago de Compostela Department of Animal Pathology Lugo Spain"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Laura","family":"Molina","sequence":"additional","affiliation":[{"name":"1 University of C\u00f3rdoba, Campus de Rabanales Department of Animal Medicine and Surgery Ctra Madrid-C\u00e1diz km 396 14071 C\u00f3rdoba Spain"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"425","reference":[{"key":"1","doi-asserted-by":"crossref","first-page":"731","DOI":"10.1016\/j.theriogenology.2009.05.006","article-title":"Applying variations of the Ovsynch protocol at the middle of the estrus cycle on reproductive performance of lactating dairy cows during summer and winter","volume":"72","author":"Alnimer M.","year":"2009","journal-title":"Theriogenology"},{"key":"2","doi-asserted-by":"crossref","first-page":"283","DOI":"10.1530\/jrf.0.0620283","article-title":"Prostaglandins and follicular function","volume":"62","author":"Armstrong D.
