There is a shortage of sawdust that can be used as bedding material in cow barns. As such, compost is sometimes used as bedding material instead of sawdust. However, compost used as bedding material in cow barns needs to have a low moisture content. We tried to produce low moisture compost by the addition of Tamari lees. We used the low moisture compost with Tamari lees as bedding material in a cow barn. The frequency of cow resting and the amount of manure contamination of cows were almost the same between the low moisture compost and the sawdust treatments. We further composted the bedding material which was used in the cow barn, and verified that the compost did not result in damage to budding and initial growth of field mustard (Brassica campestris L.) in a cultivation test. Furthermore, successful reproducibility tests were conducted to produce low moisture compost by addition of Tamari lees at another facility.
