Effects of Altering the Ratio of C16:0 and Cis-9 C18:1 in Rumen Bypass Fat on Growth Performance, Lipid Metabolism, Intestinal Barrier, Cecal Microbiota, and Inflammation in Fattening Bulls

C16:0 and cis-9 C18:1 may have different effects on animal growth and health due to unique metabolism in vivo. This study was investigated to explore the different effects of altering the ratio of C16:0 and cis-9 C18:1 in fat supplements on growth performance, lipid metabolism, intestinal barrier, cecal microbiota, and inflammation in fattening bulls. Thirty finishing Angus bulls (626 ± 69 kg, 21 ± 0.5 months) were divided into 3 treatments according to the randomized block design: (1) control diet without additional fat (CON), (2) CON + 2.5
