농산부산물 발효사료 급여가 비육흑염소의 생산성 및 영양소 이용율에 미치는 영향 = Effects of Fermented feed with Agricultural by-products on the Growth Performance and Nutrients Utilization in Fattening Korean Black Goats

다국어 초록 (Multilingual Abstract)

This study was conducted to investigate the feeding fermented agro-industrial by-products on estimating the productivity and nutrient utilization of fattening black goats. Four experimental groups were set up with each of 6 animals for a 30 days feeding trial on growth performance and 12 black goats on nutrient digestibility were allocated to 4 groups of 3 animals each by latin-square design, control (offered concentrate and rice straw) and 3 treatment groups (offered fermentation feed and rice straw). Average daily gain (ADG) showed a significant high in control group, T3 was lower than other groups (p<0.05). DM and OM intake (㎏/head) were 718.8, 680.9 g and 634.2~699.2 g, 602.8~660.4 g for control and treatment groups, respectively. As increasing of rice bran content was decreased feed intake. Digestibility of DM and OM for control group were significantly higher than treatment groups (p<0.05), and T3 treatment group with 30% rice bran was the lowest among treatment groups. Nitrogen retention was significantly higher in control and T1 groups. Thus, these results showed that productivity and nutrient utilization were similar between fermentation feeds with agricultural by-products and commercial feeds. However, this study was suggested that it must contain less than 5.0% crude fat because of feed efficient was decreased by increasing of rice bran content.

본 연구는 농산부산물을 이용한 발효사료의 급여효과를 알아보기 위해 비육 흑염소의 생산성 및 영양소 이용률을 조사하였다. 증체조사를 위한 사양시험은 거세흑염소 24두를 이용하여 처리구당 6두씩 30일 수행하였고, 소화율시험은 거세흑염소 12두를 공시하여 처리구당 3두씩 라틴방각법으로 실시하여, 처리구는 대조구(배합사료 및 볏짚 급여구)와 3개의 시험구(발효사료와 볏짚 급여구)로 각각 배치하였다. 일당증체량은 대조구가 가장 높았고, T3구가 가장 낮았다(p<0.05). 1일 두당 건물섭취량과 유기물섭취량은 시판사료를 급여한 대조구가 각각 718.8과 680.9 g, 농산부산물 첨가구가 각각 634.2~699.2와 602.8~660.4 g으로 나타나 농산부산물 중 미강 첨가구가 높을수록 섭취량이 낮아지는 경향으로 나타났다. 건물과 유기물 소화율은 대조구가 농산부산물 첨가구보다 유의하게 높았고(p<0.05). 시험구간에는 미강을 30% 첨가한 T3구가 가장 낮았다(p<0.05). 질소 축적률은 대조구와 T1구가 유의하게 높았다. 따라서, 본 연구의 결과 농산부산물을 이용한 발효사료(T1과 T2구)는 시판사료를 급여한 대조구와 비교 시 증체는 86~90%, 건물소화율은 91.7~93.1%의 수준을 보였으며, 질소이용성은 대등한 수준을 보였다. 그러나 미강의 첨가 비율이 높아질수록 사료효율 저하가 우려되므로 조지방 함량을 5.0% 이하로 배합하는 것이 필요하다 판단된다.
