What should you pay attention to when using ultrasound machines to check cattle

When using ultrasound machines to examine the pregnancy of cattle, should pay attention to: First, distinguish between fetal sac, follicles and bladder. Because the three positions are similar, and both are echo-free dark areas, it is easy to cause judgment errors; the dark area of the fetal sac is clear, and there are gray and white echo auras on the edge of the palace wall; the dark areas of the follicles are generally small, the margins are clear, no weak echo aura; the dark area of the bladder is generally large, with no obvious margins, and occasionally there are small spots of motion in the dark area. Second, the location of the exploration should be the closest to the genital area. For short breeding time (<35 days), older cattle, large uterus or sagging cattle should be detected deep in the uterine horn to avoid sinking into the uterine horn. The bottom caused a mistake.
