Application of Ultrasound Diagnosis Technology in Pig Production

Ultrasound is a kind of sound wave whose frequency exceeds 20000 Hz per second and exceeds the scope of human hearing threshold. It is abbreviated as B ultrasonic. Ultrasound diagnosis technology is safe, reliable, and has a wide range of applications. It can be used in many parts and organs of mammals, poultry, and other animals. Now introduce the application of ultrasonic diagnostic technology in pig production.

(I) Early pregnancy diagnosis of sows The conventional pregnancy diagnosis of sows is that sows that are not estrus and not pregnant after mating in the first emotional period generally have to wait until about 84 days after breeding to be sure to check them out. , Such a sow will cause about 60 days of ineffective breeding in a breeding cycle. B-ultrasound for early pregnancy monitoring, the accuracy of pregnancy diagnosis of sows who had not been pregnant in the first period of mating was more than 96%. It is at least 6% higher than the conventional method. Because it is possible to eliminate the undigested sows that have been detected in time, aggression and other measures can be given, thus avoiding invalid feeding.

(II) Providing an advanced technology for centralized breeding and control of concentrated litter production The high productivity and high economic efficiency of modern intensive pig raising, the key lies in the concentrated breeding and concentration of litters. Under normal conditions, the number of sows that are bred for conception is not easy to judge accurately. In order not to affect the yield, to make up for or avoid losses, managers are often forced to over-proportionately increase the number of breeding sows, but excessive births and farrowing tend to damage Centralized production and increased management difficulties. It may also exacerbate the reproductive function of sows and the occurrence of disease, which is detrimental to production. Due to the high accuracy of early diagnosis of B ultrasound. In this way, the management personnel's control over the number of breeding and the control of the centralized production are greatly increased, which can increase the equipment utilization and production efficiency.

(3) It is possible to make very accurate estimates of gestational age, number of pregnancies, and sex of the fetus. This is of great significance in scientific research. In particular, the estimation of the number of pregnancies and the sex of the fetus can often shorten the period of livestock experiments and improve work efficiency.

(4) Diagnostic ultrasound on livestock reproductive diseases Ultrasound has high diagnostic accuracy for embryonic death, embryo absorption and miscarriage, uterine hydrocephalus, and metritis and other reproductive diseases. This ensures the health of the female herds and improves the economy of the farm. The benefits are very important.
