The deaths of ewes during the peri-parturient period (10 days before to 7 days after lambing) were monitored in 60 flocks over two years. In the ewes that died, detailed post-mortems were performed. The incidence risk of peri-parturient deaths was 0.7%. The daily incidence rate of deaths before, at, and after lambing was 0.05, 0.04, and 0.03%, respectively. Clinical problems most frequently associated with peri-parturient deaths were pregnancy toxaemia, ruminal acidosis and post-partum genital problems. For the occurrence of peri-parturient deaths in flocks, the average lambing rate in the flocks was the only significant factor. Regarding deaths before or after lambing, the season during which lambing took place and the number of animals in the flock, respectively, were found to be significant. Most ewes (54.5%) that died at lambing (dystocia) were primigravidae.<\/jats:p>","DOI":"10.3390\/ani11082172","type":"journal-article","created":{"date-parts":[[2021,7,22]],"date-time":"2021-07-22T22:06:48Z","timestamp":1626991608000},"page":"2172","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":4,"title":["Mortality of Dairy Sheep during the Peri-Parturient Period: Results of a Field Investigation in Greece"],"prefix":"10.3390","volume":"11","author":[{"given":"Antonis P.","family":"Politis","sequence":"first","affiliation":[{"name":"Veterinary Faculty, University of Thessaly, 43100 Karditsa, Greece"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Natalia G.
