| description | The aim of this study was to investigate the effects of Korean rice wine residue
(RWR) on the growth performance and blood profiles of Hanwoo steers in the
fattening stage. In situ and in vivo
experiments were conducted to analyze rumen fermentation characteristics and
total tract digestibility, respectively. Three cannulated Hanwoo steers (mean
body weight: 448 ± 30 kg) were used in both analyses. The growth
performance of 27 experimental animals in the fattening stage (initial body
weight: 353.58 ± 9.76 kg) was evaluated after 13 months of feeding. The
animals were divided into three treatment groups (n = 9/group). The treatments
comprised total mixed ration (TMR) only (CON), TMR + 10% RWR (10% RWR), and TMR
+ 15% RWR (15% RWR). The diets of equal proportions were fed daily at 08:00 and
18:00 h based on 2% of the body weight. The animals had free access to water and
trace mineral salts throughout the experiment. Supplementation of 15% RWR
significantly decreased (p < 0.05) the rumen fluid pH
compared with the control treatment, but there was no significant difference in
the total volatile fatty acid concentration. It also significantly increased
(p < 0.05) dry matter digestibility compared with
the other treatments. The total weight gain and average daily gain of the
animals in the RWR-supplemented groups were significantly higher
(p < 0.05) than those in the control group.
Furthermore, the feed intake and feed efficiency of the RWR-supplemented groups
were higher than those of the control group. Supplementation of RWR did not
affect the alcohol, albumin, glucose, total cholesterol, triglyceride, and
low-density lipoprotein concentrations, and aspartate aminotransferase and
alanine transaminase activities in the blood; these parameters were within the
normal range. The high-density lipoprotein and creatinine concentrations were
significantly higher in the 15% RWR group, whereas the blood urea nitrogen
concentration was significantly higher in the 10% RWR group than in the other
groups. These results suggest that TMR with 15% RWR can serve as an alternate
feed resource for ruminants. |
