Abstract

The objective of this research was to determine: 1) the decomposition of proteolytic enzymes of earthworm to cottonseed meal; 2) the amino acid content in earthworm, cottonseed meal and the complex which mixed proteolytic enzymes with cottonseed meal. The results showed that the enzymatic activity of proteolytic enzymes in earthworm to cottonseed meal was high. After mixed with proteolytic enzymes, the amino acid content in cottonseed meal increased. Various proportions of essential amino acids is more reasonable. Therefore, using proteolytic enzyme can effectively improve the feed quality of cottonseed meal.
