Abstract

This study was conducted to examine the effect of feeding levels of concentrate feed on growth performance, meat quality and economic evaluation of Korean black goats. The 40 male Korean native goat were divided into four treatment groups T1 (1.5%), T2 (2.0%), T3 (2.5% feeding of concentrate feed body weight per day) and T4 (ab libitum) with ab libitum rice straw. Rice straw intake decrease as against feeding levels, however average daily gains were 22, 50, 69 and 94 g/day in T1, T2, T3 and T4 groups respectively levels (p<0.05). Dressing percentage were 41.77, 42.78, 46.12 and 49.78% in each group (p<0.05), also fat percentage were a significant increase according to feeding levels. In economic efficacy, T4 was higher than other treatment groups. In conclusion, both rice straw and concentrate feed ab libitum are good for feeding and management system on Korean black goats.

본 연구는 흑염소 비육에 있어서 조사료원이 볏짚 단용인 경우 농후사료 급여수준이 흑염소의 사료섭취량, 체중변화, 도체특성 및 경제성에 미치는 영향을 구명하기 위하여 실시하였다. 비육 흑염소 40두를 공시하여 농후사료 급여수준을 체중의 1.5% (T1), 2.0% (T2, 농가관행), 2.5% (T3) 및 자유채식구(T4)로 나누어 급여 하였고 조사료는 볏짚을 자유채식 시켰으며 그 결과는 다음과 같다. 볏짚인 조사료 섭취량은 농후사료 급여수준이 증가 할수록 감소하였으며, 흑염소의 일당증체량은 체중대비 농후사료 급여수준 1.5, 2.0, 2.5% 및 자유채식구가 각각 22, 50, 69 및 94 g으로 농후사료 급여수준이 증가할수록 유의적으로 증가하였다(p < 0.05). 비육 흑염소의 도체율은 농후사료 급여수준을 체중비 1.5, 2.0, 2.5% 및 자유채식 시켰을 때 각각 41.77, 42.78, 46.12 및 49.78%로 농후사료 급여 수준이 증가할수록 증가하였으며(p<0.05), 지방률도 농후사료 급여수준이 증가 할수록 유의적으로 증가하였다. 경제성 분석에서는 농후사료 급여수준이 증가할수록 소득은 증가하였으며, 자유채식구가 두당 34,270원으로 가장 소득이 높았다. 이상의 결과를 종합적으로 고려할 때 조사료 자원이 볏짚 단용일 경우 비육 흑염소의 농후사료 급여 수준은 자유채식 시키는 것이 사료이용성, 발육, 도체율 및 경제성에서 가장 유리할 것으로 사료되며, 흑염소의 비육을 위한 조사료 자원으로서 볏짚 단용은 농후사료비의 가중을 가져오므로 앞으로는 흑염소 비육을 위한 새로운 조사료 자원의 개발이 필요하다고 하겠다.
