Effect of Supplementing the Compost on the Yield, Chemical Composition and Amino Acid Content of Mushroom

摘要：

Dried blood and soybean meal were added separately to mushroom compost during spawning at the levels of 0, 2.5, 5.0 and 10.0％ of the dried compost spawned. The effect of supplementation on yield, chemical composition and amino acid content of the mushrooms produced were studied. Supplementation with dried blood resulted in 28. 1％ to 56. 2％ increase in the yield obtained as a result of different levels of supplementation. The addition of dried blood at 10％ level to the compost increased the amino acids threonine, tyrosine, phenylalanine, tryptophan, proline and serine with an increase of 19.4％ in the sulphr-containing amino acids. Supplementation with soybean meal resulted in an increase of lysine, phenylalanine, alanine, arginine, glutamic acid, histidine, proline and serine. Further supplementation with 5％ dried blood resulted in a yield increase of 25％ at first break, 29. 3 at second break and 22. 1％ at third break. Dry matter and protein content increased in the first and second breaks then started to decrease in the third break. The economic feasibility of introducing mushroom to the rural areas in the developing countries is discussed.
