With the development of pig farming scale and industry, Veterinary Ultrasound has gradually entered the homes of many pig farmers. Facing a scientific instrument, knowing how to use it is the most basic requirement, that is, the most routine inspection, which is very necessary.

Pig inspection: The tested sow can freely stand or lie on its side in the limit bar, and explore on the inner thigh and the outer abdominal wall of the nipple. When exploring, simply apply coupling agent to the probe and stick it on the lower abdominal wall. During exploration, there is no damage or stimulation, and it has the characteristics of short exploration time, no stress, and high accuracy. The image is intuitive, and when the black dark area of the gestational sac or fetal bone image is seen, it can be confirmed that early pregnancy is positive. Early pregnancy monitoring can be carried out as early as 23 days after mating, at which point the accuracy is already quite high.

1、 Testing site: The tested sow can freely stand or lie on its side in the restricted feeding pen, and explore on the inner thigh and the outer abdominal wall of the nipple.

2、 Postpartum sows: Adjust the viewing angle towards the spine at a 45 ° angle between the second to third pair of nipples on the ventral posterior end of the sow, and between 5-250px from the outer side of the base of the sow's milk.

3、 Reserve sow: Adjust the viewing angle towards the spine at a 45 ° angle between the top 1-2 pairs of nipples on the ventral posterior end of the sow and the outer 5-250px from the base of the sow's milk.

3、 Detection method: During exploration, simply apply coupling agent to the probe and then stick it on the lower abdominal wall.

4、 Best time: Early pregnancy monitoring can be carried out as early as 18 days after mating, and the accuracy of pregnancy monitoring can reach 100% at 22 days.

5、 Characteristics: There is no damage or stimulation during exploration, and it has the characteristics of short exploration time, no stress, and high accuracy.

For sows whose follicles have not yet matured under ultrasound observation, measures can be taken to induce estrus and try to mate them synchronously within the same week. The sows that mate at the same time are transferred to the pregnant mother's pigsty together. Ovulation is measured from estrus to find the optimal mating period. Then, early pregnancy monitoring can be carried out at the same time 18 days after mating, and ear number, age, parity (first mating), mating date, monitoring date, monitoring results, treatment suggestions, and notes can be recorded in a table.
