Effects of Dietary Supplementation of Mulberry Leaves Powder on Chicken Meat Quality Stored during Cold Storage

Abstract

This study was investigated the effects of supplementation diets with mulberry leaves powder on pH, TBARS (thiobarbituric acid reactive substance) and VBN (volatile basic nitrogen) heating loss, WHC (water holding capacity), and drip loss of chicken meat. One hundred sixty broiler were fed diets for five weeks containing 0% mulberry leaves powder (Control), 1% mulberry leaves powder (T1), 2% mulberry leaves powder (T2), and 3% mulberry leaves powder (T3). At the end of this experiment, broiler were slaughtered, and stored at 4 o C for 10 d. As storage time increased, all treatment groups resulted in increased pH, TBARS, VBN and drip loss (p<0.05). The TBARS and VBN were significantly decreased by the supplementation of mulberry leaves powder compared to the control (p<0.05). T3 results in much better TBARS and VBN than other treatment groups. Especially, T3 was significantly (p<0.05) more effective in improving self life compared to other treatment groups. Heating loss and drip loss were no significantly different among treatment group. In conclusion, these data indicate that supplementation of 3% mulberry leaves powder were most effective in decreasing TBARS and VBN.

Effects of dietary supplement of mulberry leaf (Morus alba) on growth and meat quality in rabbits

“…To our knowledge, the effects of MLP supplement on rabbit meat drip loss and chemical composition have not yet been reported. Our observation that MLP supplement decreased the meat drip loss was in contrast to the conclusion in chicken feed MLP supplement diet (Park and Kim, 2012). This may be in relating to the different animal species, and the accurate effect of MLs on meat drip loss need more advanced determination.…”

Effects of Dietary Flammulina velutipes Mycelium on Physico-chemical Properties and Nutritional Components of Chicken Meat

“…특히 다른 가축의 고기보다 살코기 중에 포화 지방산 함량이 적고, 불포화 지방산 함량이 높아 건강식 품으로서의 가치를 인정받고 있다 [8]. 최근 육계의 고급육 생 산을 위하여 다양한 약용식물 자원이 사료첨가제로 사용되고 있으며 [29,37], 그 중에서 국내 부존자원 및 농산 부산물들 또한 각종 시험을 통하여 좋은 효과를 나타내었다. Kang 팽이버섯(Flammulina velutipes)은 담자균류의 주름버섯목 (Agaricales) 송이과(Tricholomataceae)에 속하는 균으로 야생에 서 팽나무, 뽕나무, 사시나무 등의 활엽수 줄기나 뿌리를 분해 하는 백색 부후균의 하나로서 [16], 오래 전부터 인공재배에 의 해 생산되어 왔다.…”
