Abstract

This study investigates the effect of a feed concentrate on the growth performance, feed requirement, and rearing expenses of growing black goats. Forty female growing black goats were divided into four groups and fed rice straw (ad libitum) mixed with different levels of the feed concentrate: T1 (1.5%), T2 (1.8%), T3 (2.1%), and T4 (0%, control). The average daily weight gain (body weight per day) was as follows: T1 < T2 < T3 < T4 (50.23, 60.37, 71.46 and 98.90 g/day, respectively) (p<0.05). The intake of rice straw decreased significantly with increase in the concentrate level (p<0.05). Rearing expenses amounted to 46,704, 49,998, 54,701, and 74,613 won for feed concentrate levels of 1.5%, 1.8%, 2.1%, and ad libitum, respectively. Increase in feed concentrate levels led to an increase in rearing expenses. In conclusion, a concentrate level of 2.1% was determined to be idea for a rice-straw-based feed for growing black goats.

본 시험은 육성기 흑염소에 있어서 조사료원이 볏짚 위주일 때, 농후사료 급여 수준이 발육, 사료이용성 및 경제성에 미치는 영향을 구명하기 위해 실시하였다. 육성기 암컷 흑염소 40두를 공시하여 농후사료 급여수준을 체중의 1.5% (T1), 1.8% (T2), 2.1% (T3) 및 자유채식구(T4)로 나누어 급여 하였고 조사료원은 볏짚을 자유채식 하도록 하였다. 그 결과, 일당 증체량은 T1 (1.5%), T2 (1.8%), T3 (2.1%) 및 T4(자유채식)구가 각각 50.23, 60.37, 71.46 및 98.90 g으로 농후사료의 급여 수준이 높아질수록 유의하게 높았으며(p<0.05), 조사료인 볏짚의 사료 섭취량은 농후사료 급여수준이 증가 할수록 유의적으로 감소하는 결과를 보였다(p<0.05). 경제성 분석에 있어서 육성기 흑염소 경영비는 농후사료를 1.5%, 1.8%, 2.1% 및 자유 채식하였을 때 각각 46,704원, 49,998원, 54,701원 및 74,613원으로 농후사료의 급여수준이 증가할수록 경영비는 증가하였다. 이는 증체량에 있어서 T4(자유채식)구가 가장 많이 증가하였지만 T3 (2.1%)구보다 사료비에 있어서 두당 19,912원 더 많이 들었다. 이상의 시험 결과를 종합하여 고려할 때, 육성기 흑염소에 있어서 조사료 원이 볏짚 단용일 경우에는 농후사료를 2.1% 수준으로 급여하는 것이 가장 바람직할 것으로 사료 된다.
