Commercial adaptation of ultrasonography to predict pork carcass composition from live animal and carcass measurements
Article Abstract:
The applicability of ultrasound measurement in predicting pork composition in live swine and pork carcasses was evaluated. Prediction accuracy in approximating carcass value was also tested. Ultrasound approximation of pork composition was compared to actual measures obtained from carcasses. This showed that ultrasonography can be an effective noninvasive predictor of swine body composition. It was also shown that live weight and sex had the greatest influence on pork composition. It is necessary to take these factors into account in predicting carcass value using ultrasound.

Bioelectrical impedance: a nondestructive method to determine fat-free mass of live market swine and pork carcasses
Article Abstract:
The electrical reactance and resistance of pigs before and after slaughter, as well as that of pork carcasses, were measured and correlated with mass and composition to develop a methodology measuring the pork fat-free mass (FFM) using electrical impedance. Equations approximating FFM of live pigs and pork carcass were developed using regression analyses of the measures obtained. Results indicated that measurement of electrical impedance could be an effective nondestructive method in FFM estimation.

Use of bioelectrical impedance to predict leanness of Boston butts
Article Abstract:
A study was conducted to determine the value of bioelectrical impedance in predicting the leanness of Boston butts. Prediction equations of lean and fat-free muscle based on independent variables were formulated and it was shown that bioelectrical impedance is a rapid and nondestructive method of determining the leanness of Boston butts. The experiment also classified Boston butts into four categories of leanness.
