초록
Effects of dietary concentrate levels based on whole-crop barley silage (BS) on development and meat quality in growing Korean black goats were examined. A total of 36 male goats with similar age and BW were equally allocated to dietary four treatments in a randomized complete block design. Dietary treatments included controls(rice straw ad libitum plus 2.0% concentrate BW－1), and BS ad libitum plus three increasing levels of concentrate BW－1(2.0, 1.5 and 1.0%, respectively), expressed as BS 2.0, BS 1.5 and BS 1.0, respectively. The trial was lasted for 5 months from 14th of May to 12th of October, 2007. At the end of trial, all animals were slaughtered to analyze carcass characteristics and meat quality. Average daily gain was significantly(p<0.05) higher for BS 1.5 and BS 2.0 treatments than for controls. Daily feed intakes for controls(689.3 g) were significantly(p<0.05) higher than those of BS 1.0(585.5 g), but they were significantly(p<0.05) lower than BS 2.0(734.3 g). Carcass and meat percentages were significantly (p<0.05) higher for BS 2.0 and BS 1.5 than for control and BS 1.0 treatments. Shear force and water-holding capacity was greater(p<0.05) for BS 2.0 and BS 1.5 than other treatments. On the basis of feeding whole-crop barley silage to Korean black goats, as dietary concentrate inclusion levels increased, sensory results showed to have a better tendency. In conclusion, it was estimated that the optimal level of dietary concentrates might be 1.5% BW－1, when diets based whole-crop barley silage were fed to growing Korean black goats for their improvements of growth and meat quality.
Abstract
Effects of dietary concentrate levels based on whole-crop barley silage (BS) on development and meat quality in growing Korean black goats were examined. A total of 36 male goats with similar age and BW were equally allocated to dietary four treatments in a randomized complete block design.

The trial was lasted for 5 months from 14th of May to 12th of October, 2007. At the end of trial, all animals were slaughtered to analyze carcass characteristics and meat quality. Average daily gain was significantly(p<0.05) higher for BS 1.5 and BS 2.0 treatments than for controls.

On the basis of feeding whole-crop barley silage to Korean black goats, as dietary concentrate inclusion levels increased, sensory results showed to have a better tendency. In conclusion, it was estimated that the optimal level of dietary concentrates might be 1.5% BW－1, when diets based whole-crop barley silage were fed to growing Korean black goats for their improvements of growth and meat quality.
