The repeatability and accuracy of ultrasound in measuring backfat of cattle
Article Abstract:
The repeatability ofultrasound backfat measurements was determined on 217 cattle, and the association of ultrasound and carcass backfat measurements was evaluated with 580 animals, applying regression analysis on both studies. Results showed the error size between two ultrasound measures was directly proportional to the amount of backfat. Findings indicate that ultrasound measures can be more precise and accurate than carcass measures for assessing absolute backfat thickness in cattle.

Application of ultrasound for genetic improvement
Article Abstract:
Ultrasonic technology has potential applications in improving the genetic pool of domestic animals. Ultrasonic measurement of body composition provides a noninvasive and nondestructive method in assessing the value of live animals. This method has been shown to be an effective predictor of swine composition. Therefore, this nondestructive technique can be utilized in selecting parental lines with superior body composition in swine breeding programs.

Application of ultrasound for feeding and finishing animals: a review
Article Abstract:
Ultrasonic technology is evaluated as a potential predictor of carcass value in animals. Utilization of ultrasonics in predicting pork carcass composition has been effective. However, the use of ultrasound technology in evaluating sheep and beef cattle composition has not been as effective. Ultrasonic measurements approximating animal composition should therefore be interpreted and used with caution.
