ABSTRACT The objective of this study was to determine the effects of forage level in diets supplemented with chromium-methionine (Cr-Met) on rumen fluid parameters, meat fatty acid composition, and performance of Korean beef (Hanwoo) steers. Twenty-three Hanwoo steers were used in this experiment. A completely randomized design and repeated measurements were used to analyze the data set. Beef steers were fed diets containing high (10 head; average body weight (BW) = 525.1±27.5; forage:concentrate (F:C) = 60:40) (60F) and low (13 head; average BW = 531.8±32.4; F:C = 40:60 ratio) (40F) forage diets supplemented with Cr-Met for 60 d. Dry matter intake, BW, and feed efficiency were not different between the two treatment groups. Fatty acid composition of meat...

Growth performance, meat quality, and carcass characteristics in growing and fattening Hanwoo steers fed bentonite Animal Sciences
Young-Jik, Kim; Woo-Whan, Jang; Tae-Ho, Chung; In-Hag, Choi.
Thirty-six castrated, seven months-old Hanwoo steers (initial body weight: 184 ± 5.2kg) were assigned to three treatments over 23 months to evaluate the effects of supplementation with bentonite (0, 0.1 and 0.3%) on growth performance and carcass and meat characteristics. A completely randomized design with three replicates was used. The inclusion of a bentonite-supplemented diet had an influence on final weight, total weight gain, and average daily gain. Bentonite supplementation had no significant effect on proximate composition and meat quality. For carcass characteristics, there were no significant differences in yield traits and quality traits between treatments (but not cold carcass weight, marbling score, and quality grade). It was concluded that...
