Effect of Substituting Rice for Wheat in Feed Concentrate on Growth Performance, Blood Metabolites, and Meat Quality in Late-Fattening Hanwoo Steers

Key Points

• The research aims to assess how substituting rice for wheat in feed influences growth performance, blood metabolites, and meat quality in late-fattening Hanwoo steers.
• Conducted a feeding trial with 24 castrated Hanwoo steers.
• Divided steers into control (conventional feed) and treatment (33% rice replacing wheat) groups.
• Measured daily weight gain, feed intake, and food conversion ratio.
• Analyzed blood metabolite levels and meat quality characteristics.
• No significant differences in daily weight gain, feed intake, or food conversion ratio between groups (p > 0.05).
• Blood metabolite concentrations and carcass traits showed no significant changes (p > 0.05).
• TBARS levels increased significantly at day 6 of storage in the control group compared to the treatment group (p < 0.01).
