글루코사민 유도체(GD) 급여 돈육의 육질 특성

The feeding group, composed of weaning pigs fed 3mL of glucosamine derivatives, was compared for the carcass and quality characteristics with the un feeding control group for 25~70 days since they were born. The results were as follows; There were no significant differences in carcass weight and back-fat thickness between the feeding group and the un feeding group although the feeding group had low ranges of standard error when compared to the control. Feeding group had higher incidence frequencies of A grade (42.7%) than the control (29.2%). The feeding group and un feeding group had no significant differences in meat color, cooking loss, WBS, pH, WHC and purge loss. Results from this study showed that feeding GD had effect on the decrease the market weight and production of consist carcass weight, however, the feeding GD had no effect on pork quality during rearing times after weaning.
