The calculation of the pregnancy date is from the last breeding day until the fetus is born, which is generally 270-285 days. The number of days of pregnancy is affected by the species, age, season, nutrition, and the number and sex of the fetuses, with slight differences among individuals. Calculating method: month minus 3, day plus 6. For example, the cow was bred on December 15, 2000. The expected date of birth is 12-3=9 months, and 15+6=21. The cow's forecast delivery date is September 21, 2001.

3 Production
After the bovine cervix is ​​fully expanded, the contraction of the uterine fundus is stronger. If the fetal position is normal, the fetal cells will be exposed, spherical water sac, do not hurry to tear at this time to prevent the loss of amniotic fluid affecting the fetus. Ten to 20 minutes after the fetal cell is exposed, the cow must lie down and lie down to the left to prevent the fetus from being difficult to produce by the rumen pressure. When they are born, both forelimbs come out with their heads and the soft hooves are down. If dystocia occurs, the fetus should first be pushed back to the uterus to correct the fetal position, not hard pull. If they are backwards, when the two hind legs come out, the baby should be pulled early to prevent the fetus from entering the birth canal after the umbilical cord may be pressed on the pelvic floor, causing the fetus to suffocate death. Fetal output, immediately with a towel to clear the mouth, nostrils mucus, while drying the body. If it is suspended by death, the two hind legs of the newborn can be lifted, head down, hand slamming yak buttocks, so that the fetal water from the mouth, nose, and artificial respiration at the same time. The umbilical cord is broken due to the fetus's own gravity, or scissors are cut 4 to 5 cm away from the abdominal wall with sterilized scissors, and iodine sterilized with ligation to prevent infection.
After the childbirth is over, clean the dirt, replace the grass, and let the cow rest. Observe the loss of the placenta.
