Ann. Méd. Vét., 2003, 147 (6), pp 403 - 410 Prediction of carcass composition and meat quality in stress negative Pietrain pig using real-time ultrasoundYoussao A.K.I., Verleyen V., Michaux C., Clinquart A., Leroy P.L.Abstract :
The lean meat proportion and longissimus thoracis intramuscular fat percentage were predicted in negative stress Pietrain pig by real-time ultrasound using Pie Medical 200. The optimal probing site for the estimation of carcass lean content percentage was first identifed. Then, the models for the prediction of carcass lean content proportion by ultrasound measurement were developed. Somme comparison were made between Fat Lean Meter, the ultrasonic device Piglog 105 and Pie Medical 200 for lean meat proportion estimation in Pietrain carcasses. Finally, the intramuscular fat percentage was predicted from the white pixels percentage in longissimus thoracis ultrasound image. Get the PDF Contact person : pascal.leroy@ulg.ac.be |
