초록

본 연구는 비육돈에 있어서 영양소 및 원료첨가 수준이 다른 사료의 급여가 생산성, 혈중 요소태질소 및 육질특성에 미치는 영향에 대해 평가하기 위하여 시험을 실시하였다. 3원 교잡종($Landrace{\times}Yorkshire{\times}Duroc$) 비육돈 96두를 공시하였으며 시험 개시시 체중이 $63.50{\pm}1.17\;kg$이었고 66일간 개체별 사양시험을 실시하였다. 실험설계는 1) T1 (ME 3,441 kcal/kg, CP 16.30%, lysine 0.93%) 2) T2 (ME 3,433 kcal/kg, CP 17.00%, lysine 1.00%) 및 3) T3 (ME 3,449 kcal/kg, CP 17.00%, lysine 1.00%)로 3개 처리를 하여 처리당 8반복, 반복당 4두씩 완전임의 배치하였다. 사양시험 기간 동안 일당증체량, 일당사료섭취량, 사료효율 및 혈중 요소태 질소 농도는 처리구간 유의적인 차이가 없었다(p>0.05). 육색에서는 황색도를 나타내는 $b^*$값은 T3 처리구가 T2 처리구와 비교하여 유의적으로 증가하였다(p<0.05). 하지만, $L^*$값, $a^*$값, pH, 등심단면적, 드립감량, 조리감량, TBARS 및 보수력은 처리구간에 유의적인 차이가 없었다(p>0.05). 1 kg 증체에 요구되는 사료비는 T3 처리구가 높게 나타났으나 처리구간에 유의적인 차이는 없었다(p>0.05). 결론적으로, 본 시험의 결과는 비육돈에 있어서 영양소 및 원료첨가 수준의 차이가 생산성, 육질특성에 영향을 미치지 않는 것으로 사료된다.

This study was conducted to evaluate effects of dietary nutrient levels on growth performance, blood urea nitrogen, and meat quality in finishing pigs. A total of ninety six pigs ($Landrace{\times}Yorkshire{\times}Duroc$) were used in this 66 day study. Dietary treatments included 1) T1 (ME 3,441 kcal/kg, CP 16.30%, Lysine 0.93%), 2) T2 (ME 3,433 kcal/kg, CP 17.00%, Lysine 1.00% and 3) T3 (ME 3,449 kcal/kg, CP 17.00%, Lysine 1.00%). During the overall period, there were no significant differences in ADG (average daily gain), ADFI (average daily feed intake), gain/feed ratio or BUN (blood urea nitrogen) among the treatments (p>0.05). The $b^*$ value of M. longissimus dorsi muscle color significantly increased (p<0.05) with T3 treatment compared to T2 treatment. However, there were no differences in the $L^*\;and\;a^*$ values, pH, M. logissimus dorsi area, drip loss, cooking loss, TBARS and WHC (water holding capacity) for pigs fed the various treatments (p>0.05). The total feed cost per kg of weight gain was not significantly different among the various dietary treatments (p>0.05). In conclusion, these results show no effects of dietary nutrient levels on growth performance and meat quality in finishing pigs, and also suggest that a high nutrient density diet may not be a beneficial feeding strategy for finishing pigs in terms of cost.
