Determination of chemical compositions and nutritive values of the vermicompost produced by the rumen content supplementing with cattle dung, oyster mushroom (Pleurotus pulmonarius) and vegetable waste using in vitro gas production technique

Vermicomposting can feed industry and its economy play crucial role.
An in vitro gas production technique was performed to investigate fermentation response to vermicomposting produced with the epigeic earthworm, Eisenia foetida. In order to prepare vermicompost, the rumen content was mixed with the three substrates including several mixtures of oyster mushroom and vegetable waste; and cattle manure.
The treatments of T1) control: rumen content T2) rumen content vegetable waste oyster mushroom waste T3) rumen content vegetable waste cattle manure T4) rumen content oyster mushroom waste cattle manure; were adjusted using a completely random design.
The results of present study showed that, unlike having lower amount of ash, NDF and ADF; T2 had higher (P The present study revealed that the vermicomposting can be used to manage the organic wastes by biological processing to produce animal feedstuff. The results of this study indicate that the vermicomposting of the rumen content supplemented with the vegetable waste had valuable nutritive values as animal feed. The results of the present study were reported for the first time in which we investigated the application of vermicomposting of several organic waste as feed in animal nutrition. However, it is safe to say that our suggested method used in this study was the first research in which we used the several mixture of organic wastes in vermicomposting to produce animal feedstuff.
