Growing pig feed containing rapeseed dregs subjected to secondary predigestion treatment

The invention provides a growing pig feed containing rapeseed dregs subjected to secondary pre-digestion treatment, the growing pig feed contains rapeseed dregs subjected to secondary pre-digestion treatment, and the rapeseed dregs subjected to secondary pre-digestion treatment are as follows: the rapeseed dregs subjected to primary pre-digestion treatment are subjected to microbial fermentation treatment; the fermented rapeseed meal which can be directly used for animal feed preparation is formed; in the second pre-digestion treatment, the fermented rapeseed meal obtained after the first pre-digestion treatment is used as an enzymolysis substrate, and a protease combination is adopted to carry out biochemical treatment on the fermented rapeseed meal, so that the enzymolysis fermented rapeseed meal with better feed quality is formed. Through pig nutrition regulation and control and a pig feed preparation technology, the enzymolysis fermentation rapeseed meal obtained by secondary pre-digestion treatment is us
