The potential of ramie as forage for ruminants: Impacts on growth, digestion, ruminal fermentation, carcass characteristics and meat quality of goats

摘要

The objective was to evaluate the effects of ramie conserved as forage supplementation on growth, digestion, and meat quality of Liuyang black castrated goats in a 60 days 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.
