Abstract

Ovarian cysts are common pathologic structures that interfere with reproduction in dairy cattle. Studies in the 1970's effectively used manual rupture to eliminate cysts without hormonal treatment in about 45% of cases. However, reports of ovarian injuries after manual rupture deters of its wide implementation. Hormonal protocols can achieve resolution in up to 70% to 80% of cases. The objective of this study was to determine if the combination of manual rupture and hormonal treatment can help improve resolution of cystic ovarian disease in dairy cattle, compared with that of hormonal treatment alone.
