摘要
Ramie(Boehmeria nivea)is noted for the production of a large biomass that has a high protein content and is rich in antioxidants.It may thus serve as a high-quality forage material to replace alfalfa and improve the meat quality of farmed animals.In this study,we evaluated the carcass characteristics and meat quality of goats when 0,35%,75%,and 100%of dietary alfalfa was replaced with ramie.Crude protein content(linear,P<0.0001)and key muscle color values at 24 h after slaughter decreased with increasing ramie levels.The content of most individual amino acids,non-essential amino acids(NEAA),total amino acids(TAA),branched chain amino acids(BCAA),functional amino acids(FAA),and flavor amino acids(DAA)decreased(P<0.05)with increasing dietary ramie.The diet in which 35%of alfalfa was replaced with ramie yielded meat with the highest amino acid content,whereas the fatty acid profile was unaffected by the inclusion of ramie.These results indicate that ramie could be used as a potential dietary forage resource for goats,and that substituting 35%of alfalfa with ramie,which is equivalent to 126 g/kg DM content,would be optimal in terms of goat meat quality.
