2019-06-19
In a variety of livestock, cattle dystocia more. This is because the calf's pelvic axis is relatively curved, not as straight and short as horses and donkeys, so it is not conducive to the passage of the fetus during childbirth. In addition, the fetus is too large, fetal posture, position, direction is not correct, will lead to cow dystocia. Once dystocia occurs, it is very easy to cause the death of calves, but also often endanger the life of cows. Production practice has proved that the prevention of cattle dystocia must start from the spring breeding.

Once dystocia occurs, it is very easy to cause the death of calves, but also often endanger the life of cows. Production practice has proved that the prevention of cattle dystocia must start from the spring breeding.
First, do not give young cows too early mating, mating too early in childbirth prone to pelvic stenosis and so on.
Second, during pregnancy, to ensure the supply of fetal and cow nutritional needs. The feeding of reserve cattle should be strengthened to ensure that their nutritional needs are met, and breeding should not be carried out too early.
Third, for pregnant cows, appropriate exercise should be arranged to facilitate the transposition of the fetus during delivery. Appropriate exercise can also prevent diseases such as the underplacement of the placenta and incomplete uterine reset.
Fourth, early diagnosis should be made for normal delivery during labor. Check from the beginning of the work to the time when the fetal membrane is exposed or the tire water is drained. When the amniotic membrane is not broken, it is examined through the amniotic membrane. When the amniotic membrane has been broken, the fetus is palpated into the amniotic cavity. If the fetus is found to be abnormal, it should be corrected to avoid dystocia.
Fifth, for cows that give birth to their first child, the semen selection dystocia coefficient is lower8 of the bull semen or the selection of sexual control frozen semen to reduce the dystocia rate of cows.
Sixth, pay more attention to the due date and did not give birth to the cow, the cow that did not give birth, prone to pregnancy toxemia and increase the probability of dystocia, for this reason can be over the expected date of delivery.2~3 days of unproductive cattle for intramuscular injection of prostaglandin, intravenous injection of dexamethasone for birth.
Seven is reasonable selection of seed and matching, should choose good frozen semen to implement frozen matching of cows, for matching cows, first check the reproductive development of cows, such as: pelvic cavity size, birth canal, uterine development, etc.; Avoid"The calf is pregnant with a large baby" and causes dystocia.
Eight is timely midwifery, according to the expected date of delivery, do a good job of prenatal preparation, strengthen the perinatal care. When the amniotic fluid of the fetus is broken, under normal fetal conditions, grasp the two forelimbs with your hands and pull them out in an arc along the route of the pelvic axis. It can avoid dystocia caused by sheep running out of water, astringent birth canal and weak production of pregnant cows in the later period.
HKImports from GermanyMidwiferyMidwifery and installation use
Product advantages
1, the use of advanced technology in Germany, the material is lighter, the use of light.
2. The main part of the instrument carefully adopts horizontal grain technology, which is more controllable than the twill design on the market, is not easy to slip, and is easier to push and pull back and forth and has reliability.
3. Adopt German design concept, aiming at the body shape of the cow, it is not easy to damage the cow body.
Installation steps
1. Connect the upper and lower parts of the threaded pipe.
2. Insert the gray nozzle nut into the upper tube and leave a small hole.
3. The top beam is connected and tightened until it is just located in the upper hole of the pipe.
4. Put the bolt into the hole and tighten the gray connecting nut to fix the top beam.
5. Install angle pieces on the left and right sides of the top beam, and fix them with screws and nuts respectively.
How to use? Follow the basic requirements
1, the use of mechanical midwifery equipment should be familiar with the production process.
2. Be patient and don't intervene too early.
3. If the amniotic membrane (water bag) comes out, the production goes smoothly only needs 12hour.
4. Mechanical midwifery is only used in the following situations: the head is exposed first, or the two front legs and head of the cow are extended; The buttocks, hind legs and pelvis are exposed first, and there is enough space in the mother.
5. For other parts that come out first and the fetus is too large to adjust, the veterinarian should be consulted. In either case, the pressure should be used carefully, that is, start with a small force and pay attention to the correct direction of the tension. Otherwise, it will cause great damage to the mother's calf.
Precautions
Personnel who are proficient in the production process should pull out two limbs at the same time to avoid pulling out one limb and causing damage to the maternal larvae. After use, oiling the key parts of the midwifery for maintenance and cleaning.
