The invention provides a fermented feed and a production process thereof, wherein the fermented feed forms composite
fermentation strains by three groups of
lactic acid bacteria,
yeast and bacillus which have more than ten bacterial strains, the composite
fermentation strains are mixed with molasses according to the ratio of 1:1 and are mixed with
fermentation zymolyte (
cottonseed meal is mixed with
rapeseed meal with the grain size of 1.0 to 2.0mm according to the ratio of 90:10-60:40) to form fermentation material according to the ratio of 0.1 percent, after the
moisture content of the material is adjusted to 40-60 percent, fermentation of 30 plus or minus 2 DEG C is carried out for 48 hours, and expansion
drying under 80 DEG C is carried out after completing the fermentation. Compared with non fermentation, a fermentation miscellaneous
meal product produced by the production process reduces the
gossypol,
isothiocyanate and oxazolidinethione contents by more than 80 percent, improves the crude
protein content by more than 5 percent, and has the lactate content larger than 2.5 percent and pH value about 4.5. The product can substitute
soya bean meal of 30 to 50 percent in small, medium and large pig feed, the feed cost is lowered by 20 to 50 yuan /
ton, feed intake is improved by about 10 percent, the feed meal has close phase comparison, daily
gain is improved by about 4 percent, the morbidity is greatly reduced, and the
ammonia odour of a colony house is obviously reduced.
