Synopsis of recent research by authors named "Declan Marren"
Declan Marren's research focuses on the impact of grazing duration on the quality of beef, particularly examining how different lengths of pasture-based feeding influence meat composition and characteristics before finishing on a concentrated diet.
The study analyzed the longissimus thoracis muscle from suckler bulls, comparing those finished on a concentrate diet to those grazed for varying periods (99, 162, and 231 days) prior to indoor finishing.
Key findings include an increase in age at slaughter correlating with longer grazing periods, and a notable reduction in intramuscular fat concentration in bulls on pasture-based systems.*
