Abstract | This study was conducted to investigate the effects of feeding patterns of concentrates on growth performance, blood parameters and carcass characteristics in Hanwoo cows. Randomly-allocated groups, restricted concentrate feeding (T1), restricted concentrate feeding for 6 months and ad libitum 2 months (T2), restricted concentrate feeding for 4 months and ad libitum 4 months (T3), were contained with 9 animals. According to feeding patterns of concentrate, growth performance was not significantly different among the treatment groups. However, ADG tended to be higher in T2 group (0.75 kg/d) compared to the other groups (T1: 0.62 kg/d, T3: 0.72 kg/d). DMI was not significantly different among the treatment groups, interestingly, rice straw intake was significantly higher in T1 group compared with others (p<0.05). There were significant difference among feed conversion ratio, which are 17.8, 12.8, and 14.1 kg for T1, T2, and T3 (p<0.05), respectively. The serum level of albumin, triglyceride, glucose and GPT were greater in T3 group compared to other groups at fattening 6 to 8 months (p<0.05). The results of yield traits, carcass weight, back fat thickness and rib eye area were not differ among treatment groups, but yield index was significantly greater in T2 group compared to T1 group (p<0.05). The 'A' appearance rate (%) of meat yield grade was highest in T2 group for 78%. The marbling score, meat color, fat color, texture and maturity in quality traits were not differ among the treatment groups. However, marbling score and appearance rate (%) of over 1st meat quality grade were tend to be increased at T3 rather (4.0, 56%) group compared with other groups (T1: 3.4, 56%; T2: 3.6, 33%). Thus, the present study suggested that restricted concentrate feeding (1.6% of BW) for 4 months during early fattening periods and ad libitum feeding for 4 months during late fattening periods are recommendable. 본 연구는 한우 암소 비육시 배합사료 급여형태가 발육, 혈액성상 및 도체특성에 미치는 영향을 구명하고자 수행하였다. 처리구는 배합사료 제한급여 8개월(T1), 제한급여 6개월 후 자유채식 2개월(T2) 및 제한 4개월 후 자유 4개월급여(T3)로 3처리 9반복으로 완전임의배치 하였다. 배합사료 급여형태별 발육은 처리구간 유의적인 차이가 없었다. 그러나, 일당증체량은 T2 처리구(0.75 kg/d)가 다른 처리구(T1: 0.62 kg/d, T3: 0.72 kg/d)에 비해 높은 경향을 나타내었다. 건물섭취량은 처리구간 유의적인 차이는 없었지만 T1 처리구의 볏짚 섭취량이 다른 처리구 보다 유의적으로 높았다(p<0.05). 사료요구량은 T1: 17.8, T2: 12.8 및 T3: 14.1 kg으로 처리구간 유의적인 차이가 인정되었다(p<0.05). 혈청 내 albumin, triglyceride, glucose 및 GPT의 농도는 비육개시 6개월에서 8개월에 T3 처리구가 다른 처리구에 비해 유의적으로 높게 나타났다(p<0.05). 육량특성에서 도체중, 등지방두께 및 등심단면적은 처리 구간 유사한 결과를 보였는데 육량지수는 T2 처리구가 T1 처리구에 비해 유의적으로 높게 나타났다(p<0.05). 육량 A등급 출현율은 T2 처리구가 78%로 모든 처리구에서 가장 높았다. 육질특성 중 근내지방도, 육색, 지방색, 조직감 및 성숙도는 처리구간에 유의적인 차이가 나타나지 않았다. 하지만, 근내지방도와 육질 1등급 이상출현율은 T3 처리구( 4.0, 56%)가 다른 처리구(T1: 3.4, 56%; T2: 3.6, 33%)에 비해 높은 경향을 나타내었다. 따라서 본 연구는 한우 암소 비육시 배합사료의 급여는 비육초기 4개월은 제한급여(체중의 1.6%) 하고 비육후기 4개월에 자유채식하는 것이 적절한 것으로 판단되었다. |
