Carcass traits did not differ weight backfat thickness were higher castrates than gilts (p<0.01). LYW showed significant high values fat content, cooking loss, water-holding capacity (WHC) LYD (p<0.05). Redness yellowness Further, had lower pH shear...

The purpose of this study was to compare marbling score, meat quality, juiciness, sarcomere length, and skeletal muscle satellite cell (SMSC) growth related gene expression between Woori black pig (WB) the Landrace, Yorkshire, Duroc (LYD) crossbreed at different body weights (b.w.). WB developed improve quality efficiency by crossbreeding with Korean native pig. A total 24 pigs were sacrificed when their b.w. reached about 50, 75, 100, 120 kg. SMSC isolated from femoris muscles, adipose...

Effective livestock management has become essential owing to an aging workforce and the growth of large-scale farming operations in agricultural industry. Conventional monitoring methods, primarily reliant on manual observation, are increasingly reaching their limits, necessitating development innovative automated solutions. This study developed a system, termed mixed-ELAN, for real-time sow piglet behavior detection using extended ELAN architecture with diverse kernel sizes. The standard...
