The foreign research results published in 2015 were summarized on feed application, including concentrate, roughage and the mix of concentrate and roughage.Concentrate contained mainly protein feed and energy feed. The studies about protein feed nutrition mainly focused on the effects of different types of protein feeds on digestive characteristics, performance, carcass characteristics, meat quality and rumen fermentation of beef cattle. The studies on energy feed nutrition focused on the effect of types and processing technics on performance, carcass characteristics and rumen fermentation of beef cattle. Moreover, the researches about roughage, which focused on types and processing technics, was discussed in the effects on performance and digestive characteristics of beef cattle. Finally, the studies on the mix of concentrate and roughage were summarized, which mainly focused on the effects of different ratio of concentrate and roughage on performance, carcass characteristics, rumen fermentation and intaking behaviour of beef cattle. These research results were summarized and analyzed in this review, which would provide some reference for rapid development of beef cattle industry in China.
