Abstract
This study was aimed to investigate the effects of feeding level of concentrate on the digestible nutrient intake, using efficiency of nutrients and nitrogen retention of growing Korean black goats (KBG) fed on whole crop barley (WCB) silage. WCB silage with concentrates at 2.0% (BS2.0), 1.5% (BS1.5) and 1.0% (BS1.0) of BW, respectively, and rice straw with concentrate at 2.0% (RS2.0) of BW as a control. Goats for digestibility trials were assigned within each group with three animals to individual metabolism crates with Latin square design. Digestible crude protein (DCP) intakes goats in control, BS2.0 and BS1.5 was significantly higher than that in BS 1.0 (p<0.05). Digestible NFC intakes of goats in BS2.0 and BS 1.5 was significantly higher than that in BS1.0 (p<0.05). The highest Average daily gain (ADG) were recorded in group BS2.0 followed by BS1.5, RS2.0 and BS1.0 (p<0.05). The highest DM digestibility was shown in group BS1.5 treatments (p<0.05). Nitrogen retentions in RS2.0, BS2.0 and BS1.0 were significantly higher than that in group BS1.0 (p<0.05). The results obtained from this study suggested that feeding level of concentrate seems to be proper at 1.5% of BW to achieve the best performance when black goats are fed WCB silage as a roughage source with concentrate.
