After mating, cows no longer show estrus, have a mild temperament, have an enhanced appetite, and have a light, bright hair that is generally considered to be pregnant. Such as vaginal examination, cows one month after mating, when the opener inserted into the vagina, the resistance is obvious, there is a sense of dryness, vaginal mucous membranes pale, dull, uterine mouth biased to one side, was closed state, above the dark thick mucus Plug is sealed, that is pregnant; such as rectal examination, the intestine touching the uterus does not respond, or contraction of the right uterine horn, gestation angle is slightly larger than the empty angle, this is the cow has been pregnant for a month, such as the uterine horn becomes short thick , Like a thick, light-weight flashlight, there is a clear corpus luteum in the ovary. This is 40-50 days of pregnancy. If the uterine horn is a large sac, it means that it has been pregnant for 3 months. First, how to identify the birth date and delivery signs of pregnant cows? The performance of cows during childbirth: lying down at the time, frequently excreting urine, reviewing the abdomen, feel uneasy. Immediately after the contraction of the uterine muscle began to push the fetus and fetal water into the cervix, forcing the cervix open, opening to the birth canal, and later with the contraction of the fetus membrane break into the birth canal, so that part of the fetal water outflow, the fetus Place part, along the fetal water into the birth canal. At the same time, abdominal muscles or diaphragms are also strongly contracted, and intra-abdominal pressure is significantly increased, allowing the fetus to pass from the uterus through the birth canal. After another interval of 6-12 hours, the uterus contracted again and discharged the placenta, and the delivery process ended. Second, what are the best ways to prevent pregnancy in pregnant cattle? After the cow is pregnant, it must do a good job to ensure the normal development of the fetus and safe delivery, prevent miscarriage. Abortion of pregnant cows is caused by the death of the fetus in the middle of pregnancy; sudden abnormal contraction of the pregnant cows; disturbances in the function of the cow's endocrine regulation and loss of the ability to hold a baby. While the cow is pregnant within two months, the embryo is in a free state in the uterus, and the fetus relies on the uterine milk secreted by the endometrium as nutrient to absorb nutrients from the placenta. At this time, low levels of pregnant cattle, lack of uterine milk secretion, it will affect fetal development, resulting in embryonic death. In late pregnancy, the fetus develops rapidly. Insufficient nutrition and intense stimulation can also cause miscarriage. In view of the above, it is necessary to strengthen the feeding and management of pregnant cows to meet the nutritional needs, especially protein (cakes and fishmeal, etc.), to ensure supply, to add vitamin a and vitamin e; the lack of green fodder in winter and spring can be fed malt or Silage; but also to feed bone meal to prevent maternal and yak cartilage disease; to prevent mildew, acidity, frozen toxic feed; pregnant cattle should be appropriate exercise to prevent startling, whipping, sliding. Crush, reduce cavalry, stop the military service one month before birth, single-bred feeding, always ready to take delivery. Third, how to deliver the cow when giving birth? During the maternity period of the cows, special personnel should be assigned to watch and guard and the confinement work should be completed. The cows should be given clean, dry grass and a quiet environment. In a quiet environment, the cerebral cortex is susceptible to stimulation from the uterus. Therefore, strong impulses can also be transmitted to the uterus to make the uterus shrink strongly and the fetus can be quickly discharged. Generally about 10-20 minutes after the fetal membrane blisters are exposed, the cow should lie down more and more, so that it will lie to the left side so that the fetus will not be difficult to produce due to the rumen pressure. The fetus's front hoof will tear the fetal membrane and amniotic fluid (fetal water). To use the bucket to catch, use it to give postpartum cows fed 3.5-4 kilograms, can prevent the placental retention. Usually normal production is the first forehead out of the two forelimbs. If dystocia occurs, the posture is not correct. The fetus should first be pushed back to the uterus to correct the fetal position. In retrograde, when the hind leg is produced, the fetus should be pulled out earlier to prevent the umbilical cord from being pressed on the pelvic floor after the fetus's abdomen enters the birth canal, which can cause the fetus to suffocate and die. The cows are shrinking and their duties are weak. They should be sent to midwifery, tied to the fetus's two forelimb pedicels with a sterilized rope, and the assistants should pull them in. The midwife's hands are inserted into the birth canal and the thumb is inserted into the fetus's mouth, and then the jaws are pinched. When the cow is in charge, pull it hard and force it slightly towards the bottom of the cow's hips. When the fetal head passes through the vulva, one person covers both the labia and the perineum with both hands to avoid breakage. Pull out the fetal head, and then pull the action to be slow, so as not to occur uterine engorgement or prolapse, when the fetus abdomen through the vulva, hand choke the umbilicus of the fetus to prevent the umbilical cord broken in the umbilicus, and extend the umbilical time For the fetus to get more blood.
