It is a world difficult problem that the protein feed is insufficient, so developing compound protein feeds is one of the effective ways to solving this problem.

Study on producing protein feed from lactic acid residue by compound strains fermentation;

Study on protein feed production by mixed strains fermenting straw

Optimization of technology conditions about fermentation of Jatropha curcas cake with Geotrichum candidum to producing protein feed by response surface methodology

The technological conditions for production of feed protein from apple residue as raw material were investigated.

Trials of feeding-protein fermentation conditions and strains screening were conducted with four strains:Geotrichum candidum GIM2.

A growth experiment was conducted to investigate the optimum dietary protein level of juveniles of all-male sunfish.

Female larvae of silkworm were reared during the 5th instar on 5 kinds of artificial diets, which differentedin the amounts of defatted soybean meal and cellolose powder,The results showed that with the increase ofdietary protein content from 9.
