April 22, 2022, cloudy, windy.
A pregnant sheep was delivered today and it was difficult to give birth. The reason why we can't produce by ourselves is that two lambs enter the birth canal at the same time (because the sheep have two uterine horns, so the situation where the lambs to be born enter the birth canal at the same time will often be encountered in our daily breeding), so today we will talk about the several lamb fetal positions often encountered in the production of pregnant sheep, and what countermeasures we need to take.
1, smooth delivery of fetal position, head and foot climbing output, this is nothing to say.
2, the hind legs come out first, this fetal position is also more common, upside down. Directly pull out lightly on it, there is no technical content.
3, the front hoof comes out first, the mouth is at the water gate, or the head is nested inside. Response:
The mouth is at the water gate, the hoof is repeatedly sent back several times, and then the front hoof is pulled, and the other hand lifts the amniotic fluid door to the anus, the head can generally come out, after the head comes out, immediately process the mucus of amniotic fluid in the mouth and nose of the lamb, find the other leg, straighten, return to the vaginal fetal position, pull out. If the head is pinned inside, send it back a few more times, touch the head to swing the fetal position, repeat the above steps, and pull out.
Here a netizen once called me, saying that it was difficult to give birth, touched the leg, but do not know whether it is the front leg or the hind leg-------- the front leg and the hind leg are easy to distinguish: the front leg, generally near the head, can touch the head; the hind legs, generally can touch the tail.
4, Two lambs enter the birth canal at the same time. As mentioned above, the response is to push the lamb back and pull the lamb out of the front.
5, the lamb's fetal position is not correct and has not entered the birth canal, countermeasures:
Wear rubber gloves, apply cooking oil, and slowly enter the water gate to reach the cervical opening, if the uterine opening is not open, you can use your fingers to gently rotate the uterine opening a few times to expand the uterine opening. Then enter the uterus, find the hooves and head, and slowly enter the birth canal----- first lead the front hoof, then the head. If the head is not straight, just straighten it along the neck.
This is a technical content, and you must personally practice it, just listening to it is not learned, just like learning to swim, do not go into the water, master more theory, useless, should not be.
6, the lamb individual is too large. This is relatively rare, but there are also, if you can't pull it out, either the big sheep are directly handled; or the lamb is dismembered to protect the big sheep, and the anti-inflammatory strength is strengthened in the later stage; or caesarean section, in fact, caesarean section is the first choice, do it yourself the most cost-effective, let others do the cost is big.
7, when dystocia, do not beat the oxytocin, oxytocin will cause the aggravation of uterine contraction, originally difficult to give birth, uterine contraction is intense, it is easy to rupture or lead to the death of lamb suffocation, the difficulty of artificial birth will increase.
It is common to encounter new ewes, or malnourished ewes, so it is necessary for ewes to maintain adequate nutrition and exercise during pregnancy.
