February is the calving stage of the female deer. In order to ensure a smooth delivery of the female deer, it is necessary to ensure that the farrowing enclosure is quiet and avoid any abnormal disturbances. The female deer should be prepared for prenatal preparation before giving birth, such as preparing a production circle or delivery room, a deer protection fence or a cot, and preparing confinement products and midwifery utensils (such as medicine, padding, saline, syringes, liquid paraffin, etc.). Potassium permanganate, anesthetics, oxytocin, rolled ear forceps, notebook, etc.). The female deer is breast inflated about a week before giving birth. In this period, the female deer is best kept in the farrowing room. Since the female deer's farrowing is mostly at night, the staff of the day and night duty should be arranged to take care of the responsibility. People do not leave the circle and are ready to deal with special events. Observe the situation of childbirth carefully, do a good job of the birth record and the deer's nursing work, and find out the abnormal situation and deal with it in time to ensure that the female deer can deliver the calving smoothly. When the female deer breast can be extruded thick yellow liquid, swollen vulva, wrinkles spread, out of mucus, frequent urination, shaking tail, vulva vulva, look disturbed, sputum, refusal to eat, lying down when the time, abdominal pain when the child is about to give birth . When you are giving birth, take a standing posture. The first two limbs of the deer were exposed outside the female deer from the birth canal, and then the head was clamped between the two forelimbs. After several hours of delivery, the placenta was discharged and the fetus was swallowed by the female deer. After 3 minutes, the deer can stand on their own to look for the female deer breast and eat colostrum. When a female deer normally gives birth, it usually does not need a midwifery, and it is better to adopt a natural delivery method. However, veterinarians should immediately organize a midwifery if the person who has not been able to produce a deer for more than one hour of labor is deemed to have a difficult delivery. The midwifery must be based on the principle of ensuring the fecundity of the female deer. The female deer must be predominated and the fetus supplemented. The coexistence of the two is the most ideal. Cause of dystocia: First, productive dystocia, such as contraction and punish weak responsibility, contraction and premature rupture of the water, can produce uterine hernia; Second, birth canal dystocia, such as uterine twitch, uterine stenosis, vaginal, vulval stenosis And birth canal tumors; Third, fetal dystocia, fetal and maternal pelvic size is not appropriate (such as the fetus is too large, twin dystocia, etc.), fetal position is not correct, the fetus position is not correct, the fetus direction is not correct. Due to the longer limbs, the deer's dystocia is mostly fetal dystocia. In midwifery, the female deer must first be placed in a splint-type device or in a midwifery cage to allow the female deer to stand and receive midwifery. The operator should disinfect himself in advance to avoid bacterial infection and mechanical damage. Then put your hand into the vagina, carefully check the potential, fetal position and fetal orientation, is a stillborn or a live birth, to clarify the causes of dystocia, and take appropriate measures for midwifery. Midwifery measures: First, correct abnormal fetal position. The fetus is first pushed back into the womb and then the fetal position is adjusted. In order to avoid new changes, the exposed limbs can be tied with the helper rope and the fetus can be pulled out with the intermittent responsibilities. But do not use too much force, the birth canal can be injected with some soapy water or lubricants; the second is to handle the first bit of dystocia. First of all, pay attention to the correction of the position of the deer head and the two forelimbs. With the help of the production line and both hands, the fetus is corrected and gradually pulled out of the fetus afterwards. The third is to handle the tail position dystocia. First hold the fetus's two hind legs with your hands, put your hand into the uterine cavity to press down the fetal tail root, and use your force to pull the fetus down quickly. The fourth is to deal with vertical abdominal dystocia. First, use a rope to tie the hindlimb of the deer, push the forelegs of the fetus into the uterus of the female deer and turn it into a tail position and then pull out the fetus; Fifth, handle the pelvic incompetence and dystocia. After the examination and diagnosis, shreds are taken immediately to prevent damage to the female deer. If the fetus has not yet died, caesarean section may also be performed. Difficult to produce, except for special circumstances, generally do not take caesarean section. In fact, many types of dystocia in the female deer are also more complicated. Therefore, the salvage should be based on the specific circumstances and use the most effective method to make the midwifery successful. Measures to prevent dystocia: First, do a good job in the timing of bred female deer. If you enter the initial situation or sexual maturation to participate in breeding, because the female deer has not yet matured, still at the development stage of childbirth, narrow pelvis, easily lead to lack of productive forces, causing dystocia. Of course, females with over-age ages are difficult to open due to the combination of pelvises, and birth can be caused during childbirth. Therefore, it is an important measure to prevent dystocia from grasping the timing of the bred female deer. The second is to ensure the normal productivity of the female deer. Female deer intake during pregnancy lack of nutrients, disease factors, especially lack of exercise, long-term inbreeding, will affect the female deer's constitution, and thus lack of productive forces, resulting in dystocia. Therefore, to ensure the nutritional level during pregnancy, do a good job of breeding deer, strengthen the movement of female deer and prevent the occurrence of diseases, not only can increase productivity, but also can reduce stillbirth, deformity of the tire. The third is to ensure the stability of fetal growth and development conditions. The stability and suitability of female deer's living environment is the prerequisite for ensuring the normal growth and development of the female deer during pregnancy. The condition of the house is not stable, the deer house is too small or the density is too large, and the feed trough can cause deer movement and crowding during feeding. Excessive exercise, sudden apprehension or feeding with irritating foods can easily cause fetal normal fetal position and changes in the fetus, resulting in fetal dystocia. Therefore, more attention should be paid to feeding and management, and adopting scientific measures to prevent miscarriage will greatly reduce the phenomenon of dystocia and increase reproduction.
