Methods for judging veterinary B-ultrasound images

Understanding the imaging principle of veterinary B-ultrasound is that ultrasound waves will produce echoes of varying strengths when encountering different structures of animal tissues, but ultrasound waves can completely penetrate liquids and cannot produce echoes, and appear as a completely dark area on the B-ultrasound machine. For example, during pregnancy testing, when ultrasound waves encounter amniotic fluid, urine, water accumulation, etc., they cannot be directly reflected back when they encounter the amniotic fluid part, but can only be reflected back from the fetal membrane part. Therefore, the amniotic fluid part shows a dark area or what is commonly called a black hole on the B-ultrasound machine. Usually, early pregnancy testing for pigs, cattle and sheep is to find the dark area and determine whether it is amniotic fluid. If it is amniotic fluid, it can be judged as pregnancy; if it is urine in the bladder, it cannot be judged as pregnancy.

Selection of veterinary B-ultrasound detection time for various animals

Generally, different animals have different gestation cycles, and the time of pregnancy examination will also be different. Research by Boxianglai technical teachers shows that the earliest diagnosis time for veterinary B-ultrasound diagnosis of different animals is

Pregnancy examination of dairy cattle and beef cattle: the earliest examination time of veterinary B-ultrasound is 27 days after mating, which can reach 100% accuracy

Pregnancy examination of sows: the earliest examination time of veterinary B-ultrasound is 19 days after mating, which can reach 100% accuracy

Pregnancy examination of ewes: the earliest examination time of veterinary B-ultrasound is 22 days after mating and 28 days after mating, which can reach 100% accuracy

Pregnancy examination of mare: the earliest examination time of veterinary B-ultrasound is 19 days after mating, which can reach 100% accuracy

Pregnancy examination of donkey: the earliest examination time of veterinary B-ultrasound is 22 days after mating, which can reach 100% accuracy

Note: This data is the result of long-term research and experiment by Boxianglai technical team. The data will be different due to different equipment. The transmission power of B-ultrasound system can be adjusted, and the output power can be adjusted by controlling the adjustable high-voltage power supply. The specific implementation method is to control the output voltage by controlling the D/A input range.
