| The study was conducted to investigate the growth metabolism including microorganism and quality index of complex flora form crusted tea in fermented process of feed. The research results were showed as follows: (1) After 2 days fermentation, mould was not detected; Yeast reached 2.7*10^6, declined in the late period; Lactic acid bacteria growed faster in the anaerobic environment, up to 10^6; The total number of bacillus firstly rapidly increased, then remained stable.(2) The content of soluble sugar in 6 days feed fermentation process was 1.3%, increased by 8 times; The total acid content increased from 2.13 mg/g to about 23 mg/g, increased by 10.08 times. Acid soluble protein, amino acid nitrogen before fermentation for 3 days, increased rapidly, increased by 8.38 times and 10.2 times respectively; VBN increased from 12.18mg/100g to 20.61 mg/100g, then began to decline to 7.63 mg/100g. |
