|
The 587 Holstein cows which calved from January 1983 to December 1984 at an integrated dairy farm in Chung-Nam Province were investigated on incidence of retained fetal membrane. The results obtained were as follows ; 1. The incidence of retained fetal membrane was 15.2% (89 heads) among 587 heads which investigated. 2. The cows which calved in summer showed significantly higher incidence of retained fetal membrane than those which calved in winter(P<0.01), spring and autumn (P<0.05). 3. There was no difference in incidence of retained fetal membrane by calving number.
