Sheep carcass composition estimated from Longissimus thoracis et lumborum muscl...
Severiano, Silva; Guedes, Cristina; Santos, Virgínia; Lourenço, A.L.; Azevedo, Jorge Manuel Teixeira de; Dias da Silva, Arnaldo AlvesThe use of Longissimus thoracis et lumborum muscle (LM) volume measured in vivo by real-time ultrasonography (RTU) to estimate carcass composition was evaluated in 47 female sheep. Animals were scanned over six sites (7th, 9th, 11th and 13th thoracic vertebrae and 2nd and 4th lumbar vertebrae). After slaughter carcass weight (CW) and composition by dissection were determined. RTU volume measurements were calcul...
Estimation in vivo of the body and carcass chemical composition of growing lamb...
Silva, Severiano; Gomes, M.J.; Dias da Silva, Arnaldo Alves; Gil, L.F.; Azevedo, Jorge Manuel Teixeira deThe relationship between ultrasound measurements and empty body and carcass chemical composition was investigated. A 500-V real-time ultrasound with a 7.5-MHz probe combined with image analysis was used to make in vivo measurements to predict the empty body and carcass chemical composition of 31 female lambs of two genotypes, ranging in BW from 18.2 to 48.9 kg. Eleven ultrasound measurements of s.c. fat, muscle...
