Ultrasound Examination Methods for Boars Using a Porcine Swine Ultrasound System
Porcine Swine ultrasound is one of the primary methods for assessing boar reproductive performance. Visualizing the testicles, epididymis, and accessory gonads is useful for determining the causes of infertility and diagnosing boar reproductive tract diseases. Porcine Swine ultrasound examination of the boar reproductive tract must be performed with the boar in an upright position and requires transurethral introduction into a restraining pen.
High-Definition Porcine Swine Ultrasound System
A linear probe is required for transrectal scanning of the accessory gonads. For the testicles, epididymis, and spermatic cord, a convex probe or convex probe is the preferred device. Frequencies of 5.0–9.0 MHz are used. Lower frequencies are more suitable for tissues requiring greater penetration depth (i.e., the testicles and epididymal body), while higher frequencies are suitable for relatively small structures such as the epididymal head and tail. Portanto, the optimal probe and frequency will depend on the objective of the examination.
Examining the Boar Gonads Using a Linear Array Probe
Before scanning the testicles, epididymis, and spermatic cord, the scrotal surface should be cleaned and shaved if necessary. The testicles can be scanned longitudinally or transversely.

To determine testicular circumference, transverse imaging is necessary. Healthy testicular tissue is mesoechoic and has a uniform echotexture, with a hyperechoic testicle in the center (see image below).

Ultrasound images of boar testicles scanned transversely (Um) and longitudinally (B). The testicle is imaged as a hyperechoic spot in the center of the testicle (solid arrow). The boar testicular parenchyma appears mesoechoic and has a uniform echotexture. Transverse imaging also provides optimal visualization of the epididymal corpus (dashed arrow), which typically has a similar ultrasound appearance to the testicle.
Swine Backfat Meters: A Powerful Tool for Improving Reproductive Performance in the Swine Industry
With the development of the swine industry, pig backfat meters have emerged as advanced diagnostic tools to improve sow reproductive performance and increase litter size. This article will explore the relationship between backfat thickness and sow reproductive performance and introduce the advantages of pig backfat meters, aiming to provide more efficient and scientific management solutions for the pig industry.
Position for Backfat Measurement
The Importance of Backfat Thickness and Sow Reproductive Performance
Backfat thickness is a key indicator of a sow’s energy reserves and plays a crucial role in reproductive performance. Measuring backfat thickness can accurately assess a sow’s health and energy supply, leading to precise predictions of conception rate, farrowing rate, and piglet growth. Research has shown that sows with excessively low or high backfat thickness can experience reproductive problems, such as difficulty conceiving, aborto espontâneo, and reduced litter size. Portanto, properly controlling backfat thickness is crucial for improving sow reproductive performance.
Advantages and Application Value of Pig Backfat Meters
A pig backfat meter is a convenient and accurate instrument for measuring backfat thickness in live pigs. Compared to traditional manual observation and touch methods, pig backfat meters offer the following advantages:
1. Efficiency and Accuracy: Pig backfat meters automatically measure backfat thickness, eliminating manual errors and improving measurement accuracy and efficiency.
2. Real-Time Monitoring: Using pig backfat meters, farmers can monitor sows’ backfat thickness in real time, making timely adjustments to feeding and management practices to improve reproductive performance.
3. Data Management: Pig backfat meters automatically upload measured data to a computer or cloud, facilitating data analysis and management, providing a scientific basis for decision-making.
Recommendations for Using Pig Backfat Meters
To maximize the effectiveness of pig backfat meters, the following are some suggestions:
1. Correct Operation: Before using a pig backfat meter, ensure that the operator has received professional training and understands the correct usage and precautions.
2. Regular Measurement: It is recommended to regularly measure sows’ backfat thickness to monitor their health and energy supply, allowing for timely adjustments to feeding and management practices.
3. Data Analysis: Leverage the data provided by pig backfat meters for analysis and comparison, gaining a deeper understanding of the changing patterns in sow reproductive performance and making informed decisions based on the results.
As an advanced monitoring tool, pig backfat meters provide the pig industry with more efficient and scientific management solutions. By accurately measuring backfat thickness, it is possible to assess the reproductive health and energy supply of sows, thereby improving conception rates, litter size, and piglet growth. Portanto, farms should actively introduce pig backfat meters, effectively utilize their advantages, and combine them with scientific management methods to provide higher-quality products and services for the pig industry.
