Preparation method of fermented feed for crayfish

Abstract

The preparation method comprises the following steps: (1) preparing the following raw materials by weight per ton: 100 kg of soybean curb residue, 330 kg of soybean meal, 100 kg of rice bran meal, 220 kg of rapeseed meal, 50 kg of wheat bran, 79 kg of finished fish meal, 120 kg of corn or broad bean particles and 1 kg of betaine; (2) uniformly mixing the raw materials in the step (1) to obtain a mixed feed; (3) per ton of the mixed feed in the step (2), adding 100 g of beer yeast dry powder, and adding 2.5 kg of brown sugar, 10 g of lactobacillus plantarum dry powder and 10 g of bacillus subtilis dry powder into 40 L of water to activate lactobacillus plantarum and bacillus subtilis activated fermentation liquor; and (4) loading the mixed feed prepared in the step (3) into a feed fermentation breathing bag for fermentation. When the crayfish is fed with the prepared fermented feed, the crayfish is good in growth condition, compact in meat quality, steamed to eat, free of shrinkage of tail meat and high in yield.

Description

technical field [0001] The invention relates to the technical field of fish feed preparation, in particular to a preparation method of crayfish fermented feed. Background technique [0002] With the improvement of living standards and the prevalence of crayfish food culture, people's demand for high-quality crayfish is increasing, which leads to the expansion of the crayfish consumption market year by year, and the price is getting higher and higher. Breeding puts forward higher requirements, but the current production mainly uses pellet feed to feed crayfish, which leads to poor disease resistance of crayfish, and it needs to be supplemented with fish medicine to prevent diseases. At the same time, it is difficult to improve the quality, resulting in aquaculture The phenomenon that the cost is not directly proportional to the output value. Contents of the invention [0003] Aiming at the deficiencies of the prior art, the present invention proposes a method for preparing...
