At the time of gender identification, attention should be paid to: 1.Detection of cows from 55 days to 75 days of conception; the fetal reproductive nodules of cows are strongly echogenic two-leaf structure before differentiation, which is located in the tail of the fetus for easy detection.
2.When using cattle ultrasound detecting, you should first find some echoes of the umbilical cord, and then follow the direction of the umbilical cord until the umbilical hole is visible in the abdomen of the fetus. For example, a strong echo group or spot is visible behind the umbilicus. This is a male reproductive nodule, and the fetus is a male. If there is no strong echo light or spot behind the umbilicus, the fetus is the female.
