Retained Placenta
Retained placenta (RP) is also known as retained foetal membrane or retained cleansing.
RP occurs when the calf’s side of the placenta (the fetal membranes) fails to separate from the mother’s side. Separation of the membranes normally occurs after the calf is born (early separation is one cause of stillbirth). RP is usually defined as the failure to expel fetal membranes within 24 hr after parturition.
Cause
Retained placenta is most commonly associated with dystocia, milk fever (metabolic diseases) and twin births. In most herds with good management, these causes make up the majority of known risk factors for retained placenta. some infectious diseases can cause retention of the placenta.
Symptoms
The single sign associated with RP is degenerating, discoloured, and ultimately fetid membranes hanging from the vulva. Occasionally, the retained membranes may remain within the uterus and not be readily apparent, in which case their presence may be signalled by a foul-smelling discharge. Cows with retained fetal membranes are at increased risk of developing metritis, ketosis, mastitis, and even abortion in a subsequent pregnancy. infection may be viral bacterial and fungal.
• Hormonal therapy
•Anti-infective therapy
Manual removal of the retained membranes is NOT RECOMMENDED and is potentially harmful.
Prevention
There are no standard preventative regimes for infectious RP. Good dry cow management is the best way of preventing RP and reducing its effects. This will include the supply of correct nutrients, particularly magnesium, and fat-soluble vitamins, maximising dry matter intake, maintaining the correct body condition score and supplying a clean dry environment.
