Introduction

The cost of raw materials for poultry feeding has significantly increased annually. Thus, finding alternative feeds has become an important task of the feed/food industry. The mushroom industry is experiencing a global development, and the spent mushroom compost (SMC) from mushroom growing is typically recycled agricultural waste products that could thus provide a low-cost feed to animals.

Currently, mushrooms are typically cultivated within a 3-D architectural structure inside air-conditioned facilities. Substrates commonly used in mushroom production include agricultural by-products, such as cereal straw (rice, wheat, corn, and barley), cotton, cobs, husks, and pulp (), which undergo a process of mixing, high-temperature composting, pasteurization, inoculation with a pure mushroom culture, and incubation, prior to mushroom production. When the mushroom fruiting bodies mature and are ready for sale, the spent mushroom compost (SMC) is available as a by-product/waste (; ). At this stage, the compost is known as “spent mushroom compost” (SMC), and it also has nutritional components (): approximately 73.6% neutral detergent fiber, 55.0% acid detergent fiber, 8.1% crude protein, 2.1% ether extract, 9.8% non-fibrous carbohydrate, and 6.4% crude ash (). Based on this composition, SMC has potential as a feed resource for livestock. Growing Hanwoo steers were supplemented with 50% of the microbially-fermented spent mushroom substrates of the ad libitum group, which resulted in a tendency of increased live weight gain from 8 to 12%, as compared with the control group (). ) indicated that spent mushroom rice straw compost could replace 75% fresh Napoer grass (DM) for male cattle. reported that about 660,000 t of SMC (Pleurotus eryngii) were produced annually in Korea, while in Taiwan, at present, an increase of 130% means the annual production is about 80,000 metric tons of SMC.
