1 Signs of childbirth The cow undergoes drastic changes in physiology when approaching childbirth. Based on these changes, the delivery time can be roughly determined. The symptoms of childbirth are mainly as follows: breast swelling, pink nipple, labial hyperemia, swelling, wrinkling and flattening. Mucus often flows from the vagina and hangs over the vulva. The cows are uneasy and often look back at the abdomen, shouting loudly, holding high in the end, and frequently urinating. Based on these performances, you can roughly judge the delivery time.
2 Midwifery Compared with other livestock, the chance of a cow having a difficult birth is very high. Therefore, midwifery is necessary. In particular, midwifery is necessary for first-born cows, inverted cows or over-production cows. This will ensure the survival of the fetus and shorten the time of labor.
To arrange special personnel for midwifery, it is required to stay up late.
Strictly observe the disinfection system and provide cows with clean grass and quiet environment.
The process of midwifery is: When the fetal membrane is exposed, and it is not produced in time, it is necessary to determine whether the direction, position and posture of the fetus are normal. If the fetal position is not correct, the fetus must be pushed back to the uterus for correction. If it is backwards, when the hind legs are exposed, they should cooperate with the nuisance and pull the baby out in time. If the cow is in no position, use the rope to catch the two forefoot's palms. With the dubious force, alternately apply force to protect the fetal head and pull it out along the birth canal.
After the fetus has produced the fetus, it is necessary to feed a sufficient amount of wheat bran porridge, which is particularly beneficial for increasing abdominal pressure, keeping warm, relieving hunger and restoring strength.
After the fetus is produced, it is necessary to wipe the mucus at the mouth and nose with a hay or towel in time to separate the mother and child.
If the umbilical cord is naturally fractured, it should be disinfected with 5% iodine. If it does not tear, cut it 6-8 cm from the abdomen, cut it with a sterilized scissors, and then disinfect it with iodine.
Before the delivery, be sure to make preparations. Thoroughly sterilize the delivery room and prepare the equipment for delivery.
