Usually more of a worry than a problem, We've found a good mineral program will stop a lot of it, Most will shed it in a day or so, only part to watch for is cow not being able to pass urine. If that becomes a concern we use 1/2 old penicillin and 1/2 h2o2 to infuse the uterus same a i'ing a cow 20 to 40 cc will usually clear up the problem, Don't care for the bolus treatment, you have enough corruption in there without adding to it. If it's just a small portion hanging out just keep an eye on it. Ma Nature does a pretty good job.
Good luck
