Cow midwifery is an important part of timely treatment of difficult cows, correct postpartum treatment to prevent postpartum cow inflammation and calf health. Delivery is the normal physiological process of a cow. Under normal circumstances, it does not require midwifery and let it produce naturally. However, in the case of malposition of the fetus, overweight of the fetus, and inability of the cow to give birth, the cows have a certain degree of difficulty in the automatic delivery and must perform necessary midwifery. Therefore, especially for cattle farms of a certain scale, there must be a dedicated delivery room and fixed confinement workers. The delivery room should be kept quiet and hygienic, and the floor should be covered with clean upholstery. During the hot season, it is necessary to pay attention to ventilation and cooling, but you can't use high-power fans to blow cows directly. In cold seasons, warming and warming measures should be taken to increase dry grass bedding on the ground and reduce indoor humidity.
Midwife wears overalls, nails, alcohol, iodine, scissors, tweezers, cotton wool, and midwifery. Hands, tools, and obstetrical devices of midwifery personnel must be closely sterilized to prevent the introduction of pathogens into the uterus and cause diseases of the reproductive system.
When the cow is found to have childbirth symptoms, the midwife first uses 0.1% to 0.2% potassium permanganate warm water or l% to 2% coal phenol soap solution to wash the vulva or near the buttocks, and wipe with a towel dry. Then wait for the cow's delivery.
When observing that the fetal membrane has been exposed outside the body, do not rush to pull out the fetus, the arm should be disinfected into the birth canal, check the direction, position and posture of the fetus, such as the normal fetal position, allowing natural delivery. If it is backwards, after the hind limbs are exposed, the fetus should be pulled out in time, because when the fetus's abdomen enters the birth canal, the umbilical cord is easily pressed on the pelvis. If it stays too long, the baby may suffocate.
If the fetal forelimb and the head expose the vulva, but the amniotic membrane is still not broken, the amniotic membrane can be torn and the fetal mouth and mucus around the nose can be wiped so that the fetus can breathe. When the water breaks prematurely and the birth canal is dry or narrow and the fetus is too large, the vagina can be filled with soapy water or vegetable oil to lubricate the birth canal so that the fetus can be pulled out.
After the yak is produced, the mucus in the nose and mouth should be removed to wipe off the mucus from the body, and the cows can also dry themselves. At the same time, the hoof's soft hoof is removed and its initial weight is said. The midwife then sterilized the umbilical cord that had ruptured on its own with 5% iodine. If the newborn yak has a breathing disorder or if there is still a heartbeat (called asphyxiation) without breathing, I should breathe. The head of the yak was lowered first, and the hind limbs were raised. The forelimbs were held in both hands. The forelegs were moved forward and backward, and they alternately expanded and oppressed the chest. Or side-to-side hands have rhythmic compression of the abdominal ribs, requiring patience and long-lasting until normal breathing occurs.
After yak production, we must pay attention to the discharge of the cow's tires. Generally should be discharged fetal discharge after 2-8h, more than time (usually 12h, summer should not exceed 4 ~ 6h, to prevent cows womb infection caused by birthbirth corruption), it should promptly take off the tire clothing or other treatment methods .
Finally, it needs to be explained that the cow's midwifery, especially the treatment of dystocia, should be performed with the participation of the veterinarian, and the premise is to guarantee the health of the cow, especially the normal fecundity of the cow.
