1 Note Prenatal rectal examination of cattle during pregnancy is generally about 280 days. About two weeks before the birth of the cow, the fetus will change from a fetal position to a childbirth position. During this transition, when the cow is standing still, obvious fetal movement can be seen. However, whether the conversion of the fetal position, fetal position, and fetal position is normal can be determined only by rectal examination. When in front of the head, the head of the fetus can be reached in the front of the pelvis or in the pelvic cavity; when the tail is in front, the buttocks of the fetus can be touched. On both sides of the thicker digits of the fingers, the arteries have obvious gestational beats. In order to timely and accurately grasp the changes in the prenatal fetus, it is best to check every 3 to 5 days, so that you know what to do. 2 Prepare for midwifery as early as possible according to cow's childbirth signs. Before the cows mature before delivery, the maternal reproductive organs and certain parts of the body are physiological and morphological. A series of changes will occur to accommodate the need for fetal delivery and calf suckling. Such as relaxation, expansion of the birth canal, development of the breast, and enlargement of the breast. Based on these changes, the time for childbirth can be predicted, and the feeding staff can prepare for delivery and midwifery in advance. About 10 days before the cow's onset of labor, it should be transferred to the delivery room or in areas conducive to childbirth and delivery and midwifery, with special personnel for feeding and nursing. The prediction of the delivery period must not be based on a single feature. It requires a full and systematic observation and a more accurate judgment. 2.1 Changes in the genital area of ​​the cow The labia begins to increase in congestion, softness, relaxation, and wrinkles in the 1-2 weeks before delivery. When the left and right tails swing, the vulva is easily broken, the vaginal mucosa is flushed, and it is more pronounced when lying down. 2.2 Changes in the udder When the cows' gestation enters middle and late stages, under the action of estrogen and progesterone secreted by the ovaries and placenta, the mammary glands and breasts gradually develop and the breasts enlarge. In the immediate vicinity of childbirth, the breasts are larger due to the action of prolactin and begin to produce colostrum. The nipple is ruddy, thickens and hardens, and is swollen and filled with milk. The surface has a wax-like luster, and other cows stand still and spontaneously drip when they are approaching childbirth. When they lie down, they have more milk due to the abdominal wall. 2.3 changes in the cervix of cows in the pre-term factors cervical increased water thickening, relaxation, soft, closed cervical mucus suppository softened, thick and thin by a thick and smooth, showing a transparent strip into the vagina, excreted. 2.4 Changes in the pelvic ligament The softening of the pelvic ligament of the cow during the end of pregnancy has led to the occurrence of lacunae on both sides of the tail of the cow 10 to 15 days before delivery, and the lacunae on the 3rd to 5th day before the delivery have increased significantly. In short, midwifery personnel can actively prepare for delivery and midwifery preparations according to routine requirements based on the signs of the baby's childbirth. Once the cow is found to be mentally uneasy, when the appetite begins to fall, when it stops eating, when it is rested, when it is uneasy, when it is left unclear, and when the excrement is frequently excreted, the contraction starts and the childbirth has entered the first period. 3 According to the degree of dystocia of the cows, the corresponding delivery of the midwifery measures The cow's delivery is a normal physiological process. Under normal circumstances, it can be safely delivered without intervention or assistance to the fetus. At this time the midwifery personnel must monitor and care for the good livestock. When the fetal head and the two forelimbs are exposed outside the vulva and the amniotic membrane has not yet ruptured, the amniotic membrane can be torn immediately to expose the fetal nose and prevent suffocation. When the cow stands up and gives birth, use both hands to support the fetus to prevent the fetus from falling. When all the fetuses are delivered, the conscientious and midwifery staff should immediately dry the mucus on the fetal nose with a dry cloth or towel, and sterilize, ligate, and cut the umbilicus 4 to 5 cm away from the umbilicus, and finally dry the whole body of the fetus. Wool or let the cow dry. Because cows have smaller, narrower pelvis diameters, a sinusoidal arc in the pelvic axis, and fetal abnormalities, cows' dystocia is more common than other livestock. When dystocia occurs, first of all, the cow's birth canal must be checked to check whether the birth canal is narrow, dry, edematous, with or without lesions, the degree of cervix opening, the presence or absence of malformations in the pelvic birth canal, tumors, etc., and pay attention to the color and odor of the fetal water. Check the extent to which the fetus enters the birth canal (positive or inverted), the position of the fetus, the orientation and posture of the child, and determine the appropriate midwifery method. When the fetus is born, the midwife extends the index finger into the fetal mouth or gently pulls the tongue; if there is a fetus, the midwife can put his finger into the anus of the fetus, it is best to touch the umbilical cord, such as the fetus has sucking, Contraction and other reactions or obvious umbilical cord beats indicate that the fetus is alive. Care should be taken to protect the fetus during midwifery. If the fetus is dead, the fetus's injury can be ignored during midwifery. In short, there are many types of cows that are difficult to give birth and they are more complicated. Therefore, when receiving and delivering midwives, workers are required to take advantage of specific circumstances to help guide them. In addition to saving cows and fetuses, they must also pay attention to the breeding ability of their mothers and try to avoid them. Infections and injuries of the cattle birth canal, especially in the use of equipment should be careful to prevent unnecessary accidents, to achieve dual parent and child safety.
