Abstract

A component of pine bark extract, pitamin, is known as an antioxidant and antimicrobial agent that exerts a variety of physiological effects; this compound has also been used widely in human beings. A 35-day trial was conducted to determine the influence of dietary pitamin premix via a sensory evaluation and evaluations of the TBARS, and meat quality in broiler chicken. We used 4 treatments groups: Control, Antibiotics, Pitamin premix 0.1%, and Pitamin premix 0.2%. The amino acid and protein contents in chicken breast muscle did not differ among the treatment groups. The pH of broilers fed on diets containing pitamin premix was lower (p<0.05) than broilers fed on the control and antibiotics diets, whereas the WHC was significantly higher in chicken breast muscles fed on the diet containing pitamin premix compared to the control and antibiotics groups (p<0.05). The TBARS is intended to be increased during the storage period (in days), and was significantly lower (p<0.05) in the chicken thigh muscles with skin from broilers fed on the diet containing the pitamin premix as compared to the control and antibiotics group (p<0.05). The sensory evaluation of boiled chicken, with the exception of the antibiotics group, revealed significantly better results from chickens fed on diets containing pitamin premix than the control group (p<0.05). These results suggest that dietary pitamin premix may improve the shelf life, flavor, taste, and meat quality in broiler chicken.

소나무껍질 추출물인 피타민은 다양한 생리활성을 발휘하는 항산화 및 항균제로서 알려져 있으며, 이러한 물질은 또한 인간의 삶에서 폭넓게 이용되었다. 브로일러 사료 내 피타민 프리믹스가 닭가슴살의 품질특성, TBARS 평가 및 관능평가에 미치는 영향을 조사하기 위해서 35일간의 실험을 수행하였다. 실험처리구 4개는 대조구, 항생제 0.1% 첨가구, 피타민 프리믹스 0.1%, 피타민 프리믹스 0.2% 첨가구로 구분하였다. 닭 가슴살의 단백질과 아미노산 함량은 각 처리구간 통계적인 유의차가 없었다. 피타민 프리믹스 첨가사료를 섭취한 닭고기의 pH는 대조구 및 항생제 첨가구 보다도 낮았으나, 닭 가슴살의 보수력은 피타민 프리믹스 첨가구가 대조구 및 항생제 첨가구에 비해서 유의적으로 높았다(p<0.05). 닭 껍질을 포함한 다리살의 TBARS 값은 저장일수가 증가함에 따라서 높아지는 경향이었으며, 피타민 프리믹스 첨가구가 대조구 및 항생제 첨가구에 비해서 유의적으로 낮았다(p<0.05). 항생제 첨가구를 제외한 삶은 닭고기의 관능평가 성적은 피타민 프리믹스 첨가구가 대조구에 비해서 유의적으로 높았다(p<0.05). 이 결과는 브로일러 사료 내 피타민 프리믹스가 닭고기의 품질, 맛, 향 그리고 저장성을 향상시킬 수 있음을 시사해준다.
