Embodiment 1

[0011] A kind of fermented feed, shell powder 50kg, wheat bran 10kg, soybean meal powder 20kg, inoculate 0.32kg mixed bacteria, add glucose 0.032kg, add water 28kg, mix well. The mixed bacteria consisted of Lactobacillus acidophilus ACCC10637, Bacillus subtilis ACCC10619 and Candida utilis ACCC20060. The fermentation conditions were 30°C, sealed fermentation for 48 hours, and the ratio of material to water was 1:0.35. The obtained feed can be used as pig feed.

Embodiment 2

[0013] A kind of fermented feed, shell powder 60kg, wheat bran 10kg, soybean meal powder 20kg, inoculate 0.36kg mixed bacteria, add glucose 0.036kg, add water 31.5kg, mix evenly. The mixed bacteria consisted of Lactobacillus acidophilus ACCC10637, Bacillus subtilis ACCC10619 and Candida utilis ACCC20060. The fermentation conditions were 30°C, sealed fermentation for 48 hours, and the ratio of material to water was 1:0.35. The obtained feed can be used as pig feed.

Embodiment 3

[0015] A kind of fermented feed, shell powder 55kg, wheat bran 10kg, soybean meal powder 15kg, inoculate 0.32kg mixed bacteria, add glucose 0.032kg, add water 28kg, mix well. The mixed bacteria consisted of Lactobacillus acidophilus ACCC10637, Bacillus subtilis ACCC10619 and Candida utilis ACCC20060. The fermentation conditions were 30°C, sealed fermentation for 48 hours, and the ratio of material to water was 1:0.35. The obtained feed can be used as pig feed.

Abstract

The invention discloses fermented feed. Shell powder, wheat bran and soya bean meal are taken as substrates, glucose and mixed bacteria are added for fermentation, and the fermented feed is prepared, wherein the weight ratio of the shell powder, the wheat bran to the soya bean meal is (50-60):(5-10):(15-20); the adding quantity of the mixed bacteria is 2%-4% of the dry weight of the substrates; the adding quantity of the glucose is 0.2%-0.4% of the dry weight of the substrates; and the mixed bacteria comprise lactobacillus acidophilus, bacillus subtillis and candida utilis. The protein content of the fermented feed is increased by 14%-16%, the hull powder is taken for preparing the feed, so that waste is turned into wealth, and the feed cost is reduced greatly. Protein sources are added to the fermented feed, grains are saved, and an effective way for solving the environmental issue in rural areas is provided.

Description

technical field [0001] The invention belongs to the field of feed, in particular to a fermented feed. Background technique [0002] Generally speaking, the digestion and utilization rate of feed by animals is only 20% to 30%. Certain strains used as microbial feed additives can secrete amylases, proteolytic enzymes, and cellulase. This lower utilization rate is mainly due to the following two reasons: [0003] 1. The animal's own enzyme system is incomplete and the amount of enzyme is insufficient. For example, omnivores have high amylase and protease activities, but lack cellulase. At the same time, for some animals such as chickens and fish, the time for feed to be digested and absorbed in the body is only 3 to 4 hours, and the reaction time is short. These conditions make it impossible for animals to convert feed into nutrients for digestion and absorption. [0004] 2. The compound feed currently used is usually mainly plant raw materials such as corn, bran, cake, cr...
