Failure of the cervix to dilate at parturition is one of the major cause of dystocia in ewes and does in our clinic. Does respond fairly good to PG or Dexamethasone treatment. In contrast, ewes badly respond to this approach with undesirable complications for the fetus (death, emphysema, ....) and for the dam. Are there other approaches, especially when the owner do not agree to perform the CS? Also, what is the logic cause for this difference between does and ewes in response for treatment?
PG or Dexamethasone treatment can be active but Vet. clinician is good to be consulted.
PG is not a good choice because it may cause uterine rupture. Dexa or oestradiol could be helpful specially at the initial phases of parturition but in the late stages they will not effective and cesarean will the only choice.
Dear Ahmed,
The main cause about this is a failure of the estradiol level in the intrapartum time. If you have a inenought level of estradiol in the circulation blood you will have a ringwomb. So you should add a estradiol when the parturiton has began. Other point, you must put a orientation on the farmer about the reprodutor. The farmer should mantain a reprodutor that can get a small fetus.
From practical experience, PG has no effect on ringwomb on ewes and dexamethasone is clearly preferred to try. However, the dexamethasone-effect is also very variable, often with no effect. When ringwomb is present, we often give dexamethasone and start to carefully manipulate the ringwomb/cervix manually (hand/fingers). If no response or progress, CS is the last (and often the best) option for all participants, not mentioning the animal welfare point...
The costs by CS is the main aversion for the farmers, however the costs loosing a ewe and one or more lambs are higher.
PG only not effective to deal with Ring womb because if it does not cause rupture it may leads to inertia.
I personally prefer to begin with calcium therapy in saline dripping then after you my use estradiol I/M by dose of 25 - 35 mg. If it does not response CS is the only way otherwise slaughter the case, if the owner does not accepted.
You can refer our recent article “Prevalence of Dystocia in Sheep and Goats: A Study of 70 Cases (2004-2011)” published in Journal of Advanced Veterinary Research Volume 5, Issue 1 (2015) 14-20. Before this research we used lots of hormones to treat Ring womb condition. Out of all protocols the protocol used in this research were found encouraging. However there are lots of factors involved in occurrence of Ring womb condition. Therefore occurrence of this condition in a herd may be reduced by managing those conditions as well. You can go through another reference article - “Purohit, G.N., 2006. Dystocia in the sheep and goat-A Review, Indian Journal of Small Ruminants 12(1), 1-12.”
In the treatment of Ring womb condition it is very much important to look at the clinical status of the animals. Therefore in many occasions C/S becomes unavoidable before further deterioration in patient’s condition. But C/S should be conducted without undue delay and in that condition outcome is rewarding.
From practical experience we would inject with oxytocin and stimulate the cervix manually. We would lamb 1300 ewes per season and never had to c section with this method.
Just wondering if DNA samples may exist from any of these cases? Would be interested in obtaining an aliquot for future investigations.
Firs step you can use estradiol, then if it doesn't work you have to do CS.
