[Objective] To optimize solid-state fermentation of South China 5(SC5) cassava-leucaena protein feed by kombucha.[Method] The SC5 cassava-leucaena protein feed was fermented by kombucha.The fermentation conditions were optimized.[Result] The optimum conditions of solid-state fermentation were as follows:cassava and leucaena weight ratio,7:3;fermentation time,6 d;kombucha volume,10 ml;fermentation temperature,30 °C;and water volume,200 ml.The content of crude protein in feed was substantially increased and reached 23.64%.[Conclusion] The optimized fermentation process greatly improves utilization of the SC5 cassava-leucaena protein feed.
