Abstract

Twenty eight Holstein steers 12 months old and weighing about 300kg were andomly allotted into one of four groups being fed ammoniated rice straw(ARS) and substituted 30%, 40% and 50% crushed bamboo chip for ARS to determine the effects of different levels of bamboo chip on performance, digestibility and carcass characteristics. Daily weight gain was reduced as the substitution levels of bamboo chip for ARS as a roughage source increased but there were no differences in daily weight gain between steers fed ARS alone and 30% bamboo chip for ARS. Concentrates intakes were not different between treatments by the substitution levels of bamboo chip for the whole fattening period. Roughage intake tended to increase as the substitution levels of bamboo chip increased. Total feed intake was not affected by the substitution levels of bamboo chip. However, feed efficiency got worse with increasing levels of bamboo chip. Animals fed the roughage substituting 30% bamboo chip for ARS were higher in profit by 13% than animals fed ARS alone as a roughage source. Digestibilities of Dry matter(DDM) and crude fiber(DCF) were highest in animals fed ARS alone as a roughage source. DDM's were lower in higher substitution levels of crushed bamboo chip but there were no differences in DCF among animals fed different levels of bamboo chip as a roughage source. Crude protein digestibility was not affected by ammoniated rice straw or by the different levels of bamboo chip. Dressing percentage and backfat thickness were not affected by ammoniated rice straw or by the levels of bamboo chip but ribeye area was narrowed as the levels of bamboo chip increased. Beef color, fat color, texture, maturity and marbling score were not affected by feeding of ammoniated rice straw or by the levels of bamboo chip. According to these results, it may be concluded that profit can increase when Holstein bulls are castrated and roughage containing ammoniated rice straw plus 30% bamboo chip is offered.

젖소 거세우의 육질을 개선시키기 위하여 조사료원으로서 대나무(잎과 가지포함)를 암모니아 처리 볏짚 급여수준에 대하여 4 수준(0, 30, 40, 50%)으로 나누어 체중 300kg 부터 700kg 까지 급여하면서, 증체량, 사료섭취량, 사료효율, 경제성, 소화율 및 도체특성에 미치는 영향을 조사하여 다음과 같은 결과를 얻었다. 일당증체량은 대나무 30% 급여수준은 암모니아 볏짚 급여구와 차이가 없었으나 대나무 40%와 50% 급여구는 일당증체량이 감소하였다. 농후사료섭취량은 조사료중의 대나무 급여수준에 의하여 처리구간에 큰 차이가 없었다. 조사료 섭취량은 대나무 급여수준이 높아질수록 약간씩 증가하는 경향이었다. 총 사료섭취량은 대나무 급여수준 간에 차이가 없었다. 사료효율은 대나무 30% 급여수준은 암모니아 처리 볏짚 급여구와 차이가 없었으나 대나무 40% 및 50% 수준에서는 나빠졌다. 경제성에 미치는 영향을 보면 조수익에서는 대나무 30% 급여구가 암모나아 볏짚 급여구에 비하여 약 13% 높았으나, 대나무 40%와 50% 급여구는 조수익이 낮았다. 건물, 조지방, 조단백질, 가용무질소물 및 조회분 소화율은 대나무 30% 급여구와 암모니아 처리 볏짚 급여구간에 차이가 없었으나, 조섬유 소화율은 암모니아 처리 볏짚 급여구가 대나무 급여구 보다 높았고, 대나무 급여수준 간에는 차이가 없었다. 도체율과 등지방두께는 처리구간에 차이가 없었으나 배 최장근 단면적은 대나무의 급여수준이 증가할수록 점차적으로 좁혀졌다. 육량등급은 처리구간에 같은 B 등급이었다. 육색, 지방색, 조직감, 성숙도 및 근내지방도도 처리구간에 차이가 없었고, 육질등급은 처리구간에 2 등급이었다. 그러므로 본 연구에 의하면 젖소 수소는 거세를 시키고 조사료로서 암모니아 볏짚을 급여하면서 대나무(잎과 줄기포함)를 파쇄하여 30% 정도 대체 급여하면 젖소 거세우의 소득 향상을 위해 바람직하다고 사료된다.
