Retention of Placenta
Retention of Placenta
Retention of Placenta is a painful and considered to be a serious problem in animals. Even after parturition the placenta in animals does not come out, it is retained in the uterus. This condition is called as retention of placenta. Naturally placenta falls out of the uterus within 8-10 hours after parturition. In case of retained placenta, it decomposes inside the uterus, foetid discharge is observed, it stinks, animal develops high fever, milk production decreases and eventually disturbs the further oestrous cycles.
During the pregnancy period, the size of the foetus keeps on increasing so does the uterus. It takes more than 58-60 days for involution of uterus post parturition. Then the oestrous cycles start. In case of retention of placenta, this involution time of 58-60 extends disturbing the further oestrous cycle which ultimately causes anoestrous, repeat breeding and other gynaecological problems. This costs a lot to the animal owner.
Some people try to perform some unorthodox activities in the name of treatment like tying weight on the half ejected placenta outside the body to remove the remaining retained placenta, using overdoses of medicines, pulling the placenta with human efforts, which might damage the uterus. This damage can have circumstances from mere infections to permanent damage to the uterus which might make the animal infertile permanently.
What is Placenta?
In early pregnancy, the size of the embryo is very small which is nourished by the uterine milk. This Eventually when the embryonic size increases, the layers around the embryo start to develop. These layers form the placenta. The membrane towards the side of embryo is called Cotyledon and the membrane towards the side of uterus is called Caruncle.
What is the function of Placenta?
Placenta acts as a protective membrane for the embryo. The fine capillaries in Caruncle are responsible for all the transmission of nutrients, blood to the embryo.
How is Placenta expelled?
Hormones like Progesterone, Progestin, Oestrogen, Placental Lactogen play important role in the process of formation of placenta till the expulsion of placenta. The most important hormone for parturition and expulsion of placenta is Oxytocin. During the time of parturition, the progesterone level falls and oxytocin level rises which initiates the uterine contractions.
During the parturition process, the Caruncle: Cotyledon bond loosens, the capillaries in the cotyledons contract and the blood transmission from the uterus stops. During this process, the placenta is released from the uterus and the uterine contractions expel the placenta out.
How does placenta get retained?
During the process of parturition, the deficiency of oxytocin or imbalance in hormonal levels causes the disturbance in uterine contractions which eventually causes retention of placenta. The uterine contractions are supposed to continue even after the parturition to expel the placenta. In some cases, the postpartum uterine contractions also get disturbed causing the retention of placenta.
How to cope up with Retention of Placenta?
There are lots of medications available in the market for retention of placenta. The commonly available medication is the use of artificial hormones to clear the placenta. But usage of hormones must be done by the veterinary doctor as it is sensitive to handle and any smaller variation in the dosage or method of usage can cause serious problems.
LR Expellar is a herbal ecbolic which increases the uterine contractions naturally helping in expulsion of retained placenta and other tissues in uterus. LR Expellar naturally stimulates oxytocin secretion which induces uterine contractions. Being a uterine tonic, LR Expellar improves the process of involution, makes uterus ready for next pregnancy and maintains overall health of uterus.
