ABSTRACT

Abbasvali M, Shekarforoush SS, Aminlari M, Effect of electrical stimulation on ovine carcasses. Onl J Vet Res, 29 (9): 551-562, 2025. We report effect of 100 or 150V, 50 Hz for 60s on meat quality of 6 male sheep carcases. After samples were stored at 25 °C for 4 h, followed by chilling at 6 °C for 14 days. Stimulation reduced meat pH ~0.9 units (~15%), adenosine triphosphate ~29% (P<0.05) and calpain ~30% over 24h. Stimulation reduced water retention ~21% (P<0.05). We found no effect on muscle temperature or color of carcasses. Results suggest post-mortem and meat quality were affected by electrical stimulation, early rigor mortis temperature and ageing but 150v, 60 sec showed greater effects than 100V.

Keywords: Electrical stimulation, carcass, tenderness, sheep; pH, ATP, water retention.
