Abstract

This study was conducted to investigate the optimal energy level at growing Korean black goat from April 20 to November 6, 2006. Forty male Korean black goat were divided into four treatments and were fed with concentrate feed containing ME 2.4, 2.6, 2.8 and 3.0 Mcal/kg with CP 15% and rice straw. Average daily gains of were 59.8, 65.4, 73.2 and 77.2 g/day in groups fed with ME 2.4, 2.6, 2.8 and 3.0 Mcal/kg diet, respectively. There was a tendency to increase ADG as the ME level of concentrate feed grew. Dressing percentage were 49.73, 48.64, 50.19 and 51.36% in each group, and were increased as the ME level grew. Meat percentage ranged between 53.1 and 55.3%, and were almost constant. Ranges of crude fat contents and water holding capacity were and 57.9~59.0%, which were increased as the ME level grew. On the other hand, shear force were between 2.8 and 3.1 kg/cm2, which were decreased as the ME level grew. These results suggest that the optimal energy level at growing goat's concentrate is ME 3.0 Mcal/kg.

본 시험은 사료의 에너지 수준이 육성기 흑염소의 발육과 육질에 미치는 영향을 구명하기 위하여 흑염소 육성축 수컷 40두를 공시하여 대사에너지 수준을 각각 2.4, 2.6, 2.8 및 3.0 Mcal/kg로 하여 2006년 4월 20일부터 2006년 11월 6일까지 시험을 실시하였으며 그 결과는 다음과 같다.일당증체량은 대사에너지 2.4, 2.6, 2.8 및 3.0 Mcal/kg구가 각각 59.8, 65.4, 73.2 및 77.2g으로 사료의 에너지 수준이 높을수록 증가하는 경향이었고, 사료요구율은 각각 9.87, 8.88, 8.11, 7.19로 감소하는 경향이었다. 사료의 에너지 수준에 따른 도체특성은 에너지 수준이 증가함에 따라 도체율은 각각 49.73, 48.64, 50.19, 51.36%로 증가하는 경향이었으나 정육율, 지방율, 뼈율은 에너지수준 간에 차이가 없는 것으로 나타났다. 육질특성은 일반조성분인 조지방 함량은 사료의 에너지 수준이 증가함에 따라 증가하는 경향이었고, 물리적 특성인 전단력, 가열감량 및 보수력은 대사에너지 3.0 Mcal/kg에서 각각 2.82㎏/cm2, 29.6%, 59.0%로 다른 처리구보다 육질이 우수한 경향을 나타내었다. 이러한 결과를 종합적으로 고려할 때 육성기 흑염소의 발육과 육질개선을 위한 사료는 사료의 CP함량이 15%일 경우 대사에너지 수준은 ME 3.0 Mcal/kg이 적정한 것으로 사료된다.
