In daily pig farm management and production, the three keys to using good ultrasound for pigs are indispensable, so what is the best time to measure pregnancy? What is the best time to measure pregnancy? Is there any difference in ultrasound imaging for different days of pregnancy? Dawei veterinary ultrasound for pigs, in the early pregnancy monitoring of sows as early as 18 days after breeding can be carried out, 20-25 days between the judgment of pregnancy monitoring accuracy of up to 100%. Because swine ultrasound pregnancy detection, mainly through the measurement of the amniotic fluid inside the pregnancy sac to judge, if the sow is pregnant, in the swine ultrasound image shows a black spot (i.e., dark area), and in this time period amniotic fluid ratio is the highest, the formation of the black spot is also the best to recognize the judgment. Therefore, 20-25 days after breeding is the best time to use ultrasound to detect pregnancy!
The following phases need to be noted during the 25 days after confirmation of pregnancy:
Stage 1: Loin adjustment period (30 to 85 days)
During this phase, the amount of feeding needs to be adjusted according to the sow’s loin condition.
Stage 2: Mammary gland development stage (85 days to 95 days)
At this stage, the feeding amount needs to be reduced appropriately to avoid mammary gland underdevelopment with fat accumulation, which will affect the ability of milk production in the later stage.
Stage 3: Tapping period (after 90 to 95 days)
During the period of attacking the fetus, the timing of attacking the fetus needs to be determined according to the sow’s fat and the size of the abdominal circumference, but it should not be carried out too early. Usually, the work of tapping the fetus is started after 90 days, and the feeding amount during the tapping period is adjusted according to the data of the past piglet’s first-born weight.
