This study was conducted to examine the feeding effects of FFWBG (fermented feedstuff with wet brewer’s grain) and GS(grinding soybean) in Hanwoo steers. For this research, total twenty steers(average body weight : 455.7$\pm$25.9kg) were grouped into control(formula feed), T1(formula feed:FFWBG=60:40), T2(formula feed:GS=80:20), T3(formula feed:FFWBG:GS=50:40:10), and T4(formula feed: FFWBG:GS=40:40:20), each treatment was allocated to four steers. There was a tendency to be increased average daily gain in T1, T2, T3 and T4 compared with the control even though no statistical significance was found. The feed conversion of T1, T2, T3 and T4 were beneficially better than that of control(P<0.05; 8.25, 9.44, 6.69 and 7.71 vs 11.90, respectively). The blood urea nitrogen concentration of T4 was higher than that of control(P<0.05), but the creatinine concentration of T4 was lower than that of control(P<0.05). The glucose concentration of T1, T2, T3 and T4 were higher than that of control(P<0.05; 59.39, 62.44, 62.17 and 54.00 vs 51.00mg/$d\ell$, respectively). The back-fat thickness of T3 was thicker than that of control, T1, T2 and T4. The rib-eye area of T1, T3 and T4 was wider than that of control. Appearances percentage of ‘A’ ranked meat quantity were 66, 33, 75 and 33% in control, T1, T2 and T4, respectively.

This experiment was carried out to investigate effects of fermented feedstuff added Saccharomyces cerevisiae(FFSC) on growth performance and carcass grade of growing Hanwoo bulls. Twenty six Hanwoo bulls averaging 230$\pm$24kg were randomly assigned within two dietary treatments which were control and FFSC. Average daily gain and feed intake were significantly higher in FFSC compared with control during growing, fattening and finishing period. Feed conversion was improved in FFSC compared with control during fattening and finishing period. During the whole experimental period, average daily gains were 1.06 and 0.98kg in FFSC and control, respectively, and it indicated that 19% was improved in FFSC compared with control(P<0.05). Feed intake was not significantly different between treatments during whole experimental period. In addition, feed conversion was not significantly different between treatments, there was a tendency to be beneficially increased about 7% in FFSC compared with control. There was no differences on yield traits including carcass weight, dressing, back fat thickness, rib-eye area and meat production between treatments. Marbling score was improved in FFSC compared with control(P<0.05). Appearances of ‘A’ ranked meat quantity were 44.4 and 25.0% in FFSC and control, respectively. Only FFSC had ‘1’ ranked appearance, but there was no ‘1’ ranked appearance in the control.

최근 지속적인 국제곡물가격 상승과 해상운임의 급등으로 국내 사료원료의 도입가격 상승 또한 계속되고 있다. 미국 Gulf 지역에서 한국으로 오는 해상운임비는 2002년 톤당 20~25불에서 최근에는 75~80불대로 급등하였으며, 국제 곡물재고와 생산량 감소로 미국산 사료용 옥수수의 국내 도착가격은 톤당 173불대로 전년 132불에 비하여 59%, 대두박은 톤당 313불대로 전년 208불과 비교하여 78%, 사료용 소맥은 185불로 전년 104불과 대비하여 50%가 각각 상승하였다.<중략>

양축농가(단위 동물 기준)의 생산비 가운데 사료가 차지하는 비율은 통상 60$\%$정도다. 이러한 높은 비율의 사료비를 절약하는 방법으로는 지금까지 주로 사료의 허실을 방지하는 것으로 가장 많이 고려되어왔다. 하지만 무더운 여름철엔 높은 온도와 습도등으로 인해, 자칫 사료의 질이 떨어지기 쉽고 성장능력이 감소하고 생산성도 떨어지기쉽다. 하지만 이는 눈에 뚜렷하게 보이지 않는다는 이유로 거의 무시되어 왔다. 따라서 이 글에서는 무더운 여름철에 사료에서 어떤 문제점이 발생하며, 그 해결방안은 무엇인지를 살펴 보기로 한다.
