Assessing dual-energy X-ray absorptiometry prediction of intramuscular fat content in beef longissimus steaks

Dual-energy X-ray absorptiometry: an effective approach for predicting broiler chicken body composition

“…The equipment software uses the reduction of the dual X-ray beam caused by distinct absorbing materials to estimate the values of total tissue, soft lean tissue ( SLT ), fat tissue, bone mineral content ( BMC ), and fat percentage in the projected figures ( Schallier et al, 2019 ). DEXA has been proven useful in animal science; its application varies between prediction of intramuscular fat in beef steak ( Nunes et al, 2023 ), body composition of swine ( Soladoye et al, 2016 ; Kasper et al, 2021 ), body composition and phosphorus retention in rainbow trout ( Ndiaye et al, 2020 ), mineral density and content in laying hens ( Hester et al, 2004 ; Schreiweis et al, 2004 ), broiler bone resistance ( Shim et al, 2012 ), and growth performance ( Castro et al, 2019 ; Meyer et al, 2019 ). Furthermore, DEXA is a promising noninvasive method for longitudinal studies to determine fast heating production, and consequently net energy requirements of chicken growth ( Martinez et al, 2022a ; Suesuttajit et al, 2022 ), and longitudinal studies about potential body growth of broiler and pullet strains ( Alves et al, 2019 ; Gonçalves et al, 2020 ).…”
