In the case of captivity, ewes are prone to dystocia because of their good nutrition and less exercise. After the ewe's amniotic fluid ruptures under normal circumstances, the lamb will be born within 30 minutes. If the lamb is unborn or has obvious production difficulties for more than 30 minutes, the breeder should prepare artificial midwifery.

1. Normally produced ewes do not need midwifery

Many ewes obviously can produce normally, but some breeders always like to “help” one and pull the lamb from the ewes. This practice is not desirable. First of all, no production squeeze is not conducive to lambs discharging amniotic fluid from the body. Secondly, it is very easy to cause unnecessary damage to the ewes' birth canal.

2, the basic method of ewes midwifery

Difficulties caused by oversized lambs or narrow birth canals: Infuse paraffin oil or warm soapy water into the ewes' birth canal, then carefully insert them into the ewes' birth canal to forcibly pull out the lambs, and pull them with the responsibility of the ewes. . In the event that it cannot be pulled out, a special cut-out shear can be used to decompose the lamb to protect the ewes.

Dystocia caused by malposition of the fetus: Keeping the ewes in low and high positions, push the lambs into the uterus for adjustment, and then pull them out or let the ewes produce themselves.

Ectopic dystocia caused by abnormalities: Excluding factors such as oversized lambs or malposition of fetuses, simply due to dystocia caused by eczema contraction and weak responsibility. You can retreat the ewes to stimulate the uterus to contract. More than 30 lambs are still born. The ewes can be injected subcutaneously with 2 to 3 ml of pituitary injection or 1 to 2 ml of ergot injection, or 1 to 5 mg of fresh ergot.

3, lamb care

After the lamb is born, it should be cleaned up to mucus in the mouth and nose so that it can normally breathe air. Difficult-to-produce lambs can easily inject mucus, such as amniotic fluid, into the deep part of the nose or lungs. The lamb can be lifted and thrown gently to promote mucus discharge. Then let the ewes dry or manually wipe the mucus on the lambs to avoid the loss of body temperature.

Lambs should also eat colostrum as soon as possible to obtain maternal antibodies. Due to the generally weak body composition of difficult-to-fetch lambs, and no self-feeding capacity, manual feeding should be used to make them eat colostrum.

4, ewes care

Ewes can use 250 grams of brown sugar and bran, plus boiling water 2000~3000 ml, and cold to 40~45°C for ewes to drink, which can restore the ewes' physical strength, supplement and regulate intestines. At the same time, 7 days after the birth, 50 grams of motherwort was used to drink water for the ewes to promote the discharge of lochia and recovery of the uterus.

For artificially assisted ewes, postpartum anti-inflammatory should be strengthened. Houttuynia injection 10-20 ml, penicillin 320-4 million units, and enrofloxacin 0.25 g can be used for intramuscular injection once a day for 3 days.
