Ninety Texel ewes were investigated during seasonal anoestrous. The ewes received intravaginal sponges containing MAP (60\u2009mg) for nine days. At the time of sponges' withdrawal, the ewes were divided into three groups (G): (1) receiving 2\u2009mL of saline i.m.

Twelve h after sponges' removal, teaser rams were used to estrus check and remained with the ewes for 96\u2009h. The artificial insemination was made with fresh semen 10\u2009h after estrus detection. The effect of the treatment was not significant for the estrous rates among the groups: 73%, 90%, and 86%, respectively. The main effect was observed in the pregnancy and lambing rates among the groups: 70%, 86%, 56%, and 80%, 120%, 56%, respectively. Based on these results from our study, the use of the MAP\u2014eCG is the best choice to improve the fertility rate on ewes.<\/jats:p>","DOI":"10.4061\/2010\/978520","type":"journal-article","created":{"date-parts":[[2010,9,30]],"date-time":"2010-09-30T06:06:11Z","timestamp":1285826771000},"page":"1-4","source":"Crossref","is-referenced-by-count":8,"title":["Fertility Rates of Ewes Treated with Medroxyprogesterone and Injected with Equine Chorionic Gonadotropin plus Human Chorionic Gonadotropin in Anoestrous Season"],"prefix":"10.4061","volume":"2010","author":[{"given":"I.
