摘要： This study was conducted to evaluate the use of ramie as forage on growth performance, serum biochemical indices, and meat quality of Boer goats. For this, 60 Boer lambs were divided into four groups fed the TMR with 0%, 10%, 20%, and 40% (control, and groups I, II, III, respectively) ramie. The experiment lasted for 90 days with a pretest for 15 days. Venous blood and longissimus dorsi (LD) muscle samples were collected after 24 h fasted at the end of the experiment. The results showed that ramie seems no significant changes in average daily gain (ADG) and other parameters for growth performance, only 40% ramie in TMR significantly reduced average daily feed intake (ADFI) (P < 0.05). Compared to the control, group II (20%) showed significant increases in total protein (TP) and globulin (GLB) levels, and decreases in albumin/globulin level (P < 0.05) in serum. Meanwhile, serum total cholesterol (TC) (P < 0.05) and free thyroxine (FT4) level were significantly reduced with up to 20% or more ramie in TMR. Moreover, the total amino acid and flavor amino acid levels in LD muscle were not affected by ramie. However, significant increases (P < 0.05) were observed in linoleic acid, polyunsaturated fatty acid, and polyunsaturated fatty acid/saturated fatty acid levels in group II. Overall, these results indicated that up to 20% ramie in TMR have no impairment in growth performance, health and meat quality, whereas high level ramie might have a negative effect on feed intake.
