초록

본 연구는 한우 암소의 산육 및 도체특성에 있어 오징어 부산물의 급여 효과를 알아보기 위해 수행되었다. 한우 16두(나이 7세, 체중$484.1{\pm}63.6$ kg)를 대조구 및 처리구(오징어 부산물 첨가), 등 2그룹(각각 8두)으로 완전임의 배치하였다. 사료급여는 두 그룹 모두 자유채식토록 하여 150일간 시험을 수행하였다. 일당증체량은 처리구가 대조구 보다 유의적으로 높았다(p<0.05). 시험기간 내 사료섭취량 및 사료요구율은 처리구가 대조구 보다 유의적으로 낮았다(p<0.05). 육량특성에 있어서, 등지방두께, 등심단면적 및 육량지수는 두 처리구간 비슷한 경향을 나타내었고, 도체중은 처리구가 363.4 kg 대조구 353.1 kg으로 처리구간 유의적 차이는 없었다. 육질특성에서는 육색, 지방색, 조직감 및 성숙도는 두 그룹간 유의적 차이가 없었다. 그러나 근내지방도 및 육질 1등급 이상 출현율은 대조구 보다 처리구가 높았다. 그러므로 본 연구의 결과 오징어부산물의 급여는 한우 암소의 산육 및 도체특성을 향상시키는 것으로 생각된다.

This study was conducted to evaluate the effect of feeding squid by-products on the growth performance and carcass characteristics of Hanwoo cows. Sixteen Hanwoo cows, aged 7 years and weighing $484.1{\pm}63.6$ kg, were randomly allocated to 2 feeding groups (8 animals per group): control and treatment (fed squid by-products). Both groups were fed ad libitum for 150d. Average daily gain was significantly higher in the treatment group than in the control group (p<0.05). During the experimental period, DMI and feed conversion ratios were significantly lower in the treatment group than in the control group (p<0.05). The results of yield traits, back fat thickness, rib eye area, and yield index were similar between the two groups. Carcass weights were 363.4 kg and 353.1 kg for treatment and control, respectively, but these differences were not statistically significant. Quality traits such as meat color, fat color, texture, and maturity were also not significantly different between the two groups. However, marbling score and rate of appearance of high quality grade ($1^{++}$, $1^+$, and 1) were higher in the treatment group than in the control group. These results suggest that feeding squid by-products may improve the growth performance and carcass characteristics of Hanwoo cows.
