The low-fish-meal-content compound pellet feed is comprehensive and balanced in nutrition and meets the nutrition demands of the young Chinese soft-shell turtles. Compared with current commercially available commodity feed for the young Chinese soft-shell turtles, the production cost is remarkably reduced, breeding effect is good, and feed coefficient is low.

Method for preparing feed raw materials by solid state fermentation of tea dregs
The invention discloses a method for preparing feed raw materials by solid state fermentation of tea dregs, and relates to the field of feed processing. The method is as follows: mixing tea dregs, bean pulp, bran, molasses and composite trace elements as fermentation substrate according to a certain mass ratio, adjusting water content, adding 4 kinds of bacteria such as bacillus subtilis, saccharomyces cerevisiae, aspergillus niger and lactic acid bacteria, controlling fermentation conditions, and performing enzymolysis and aerobic and anaerobic combined fermentation to obtain the product. According to the tea dreg solid state fermentation feed produced by the method of the invention, the method effectively reduces the crude fiber content of the tea dregs, improves the protein content, andis suitable for industrial production of feeds.
