Abstract
In order to examine the effect of treated and untreated retained placenta (RP) on fertility and on the occurrence of puerperal and fertility diseases, the records of 248 cows with RP were examined: 199 cows were treated with intrauterine tetracyclin or systemic therapeutics, and 49 were left untreated. One hundred and ninety-six herd mates without RP served as controls. The fertility of the cows with RP was lower than that of the controls. The effect of treatment on fertility was neither beneficial nor harmful. The untreated cows with RP seemed to be treated more often for endometritis and repeat breeding than either the treated animals or the controls. Mastitis within 1 week after calving was more common in both groups of RP cows than in the controls. Most cases of mastitis in the treated RP group could be diagnosed at the time of RP treatment.
