Abstract

The objective was to evaluate the effects of ramie conserved as forage supplementation on growth, digestion, and meat quality of Liuyang blackcastrated goats in a 60days feedlot study. Forty-eight goats were randomly assigned to each of four treatments: 24% rice straw+36% ramie residues silage+40% concentrate; 24% rice straw+36% raw ramie silage+40% concentrate; 24% rice straw+36% ramie residues hay+40% concentrate; 24% rice straw+36% raw ramie hay+40% concentrate. There was an increased tendency for ADG in ramie hay treatment than that of ramie silage treatment (p=0.067). There was an increase for the apparent digestibility of DM, CP, NDF, and ADF in the ramie hay treatment than that of ramie silage treatment (p≤0.034). An increased tendency was found for C18:1n-9c (% of total fatty acids) in the longissimus dorsi muscle of raw ramie treatment versus ramie residues treatment (p≤0.087). These results indicate that the ramie hay or raw ramie treatment had a tendency for improving the nutrient digestibility and meat quality of goats than that of ramie silage or ramie residues treatment, respectively.
