摘要

The addition of raw rapeseed cake (RRC) to broiler feed may avoid the negative effects of soybean meal (SBM), including its genetically modified origin, environmental impact, and nonprospective flexible price. Processing RRC through fermentation has also been shown to be beneficial: adding fermented rapeseed cake (FRC) to the broiler diet is a nutritional approach that addresses both the environmental issue of broiler enteric methane emission and the economic issues of soybean meal. The aim of this study was to assess the effects of partial replacement of soybean meal by a 15% addition of RRC or FRC to the diets of broiler chickens on methane emission, nitrogen retention, ether extract digestibility, growth performance, and breast muscle fatty acid composition. The FRC did not show any unfavorable effects on growth performance or nutrient utilization, and it improved the fatty acid profile of the breast muscle; additionally, both methanogens and methane emission from the fermentation of cecal contents were significantly limited. In conclusion, FRC as a partial substituent may be a valuable alternative to soybean meal in broiler chicken nutrition.
