Effect of Different Levels of Mushroom Waste (Agaricus bisporus) with or without Probiotic on Growth Performance, Carcass Characteristics, and Breast Meat Quality in Broiler Chickens

Abstract

The aim of this study was to investigate the effect of mushroom waste and probiotic levels on growth performance, carcass characteristics, and meat quality in broiler chickens. A 2 × 3 factorial arrangement with two levels of probiotic supplementation (0 and recommended rate) and three levels of mushroom waste inclusion (0%, 3%, and 6%) was used in a completely randomized design using male broiler chickens (Ross 308 strain). Different levels of mushroom waste and probiotic had no significant effect on body weight gain and feed conversion ratio in broiler chickens. Neither different levels of mushroom waste nor probiotic independently had any significant effect on carcass characteristics. However, the use of mushroom waste and probiotics significantly reduced the malondialdehyde content in chicken breast meat 30 days after storage (P). Breast meat pH value was significantly reduced by supplementation with probiotic 1 and 30 days after storage (P). In conclusion, under the conditions of this experiment, inclusion of mushroom waste, particularly at 6% level, numerically improved growth performance and was effective in preventing meat oxidation.
