Embodiment 1

[0034] Add 4% Lactobacillus plantarum, 0.3% Bacillus cereus and 4% molasses in the aquatic feed, add water to adjust the water content of the feed to 30%, adjust the pH value to 6.5, stir evenly, divide into thick plastic bags, tie Tighten the mouth of the bag and ferment for 24 hours at room temperature. The experiment was repeated three times, and the results are shown in Table 2.

[0035] Table 2 Feed predigestion treatment results

[0036]

[0037] As can be seen from the data in Table 2: the results of the pre-digestion treatment of the 3 batches of 500kg feed are similar, and the average values ​​of plant Lactobacillus, Bacillus cereus, water content and pH value in the fermented feed are respectively: 10.3×10 8 cfu / g, 6.1×10 8 cfu / g, 31% and 5.1, golden color, light fragrance. It shows that the process of feed predigestion treatment provided by the present invention is stable, and can be used for large-scale feed predigestion treatment in vitro.

Embodiment 2

[0039] Effects of Predigested Feed on Growth and Disease Resistance of Tilapia

[0040] This example was carried out in the outdoor cement pool (1.5m×3.0m×1.2m) of Guangxi Fisheries Research Institute Haike Haile Company from July 15 to September 15, 2018. The average weight of initial stocking with uniform specifications was 6.18 200 test fishes in g were randomly divided into 2 groups after being domesticated for 7 days, and each group had 2 replicates, with 50 fish in each replicate. The control group was fed with basic feed; the test group was fed directly after the feed was predigested according to the process of Example 2. After feeding for 60 days, the weight gain rate, survival rate and feed factor were calculated respectively, and streptococcus suspension was sprayed in the water body of each treatment group for challenge test, the cumulative death of tilapia within 15 days was counted, and the cumulative survival rate was calculated. The test results are shown in Ta...

Abstract

The invention provides an aquatic feed pre-digestion method, and belongs to the technical field of feed processing. The pre-digestion method firstly mixes an aquatic feed, lactobacillus plantarum, bacillus cereus and molasses according to a mass ratio of 100:2-6:0.2-0.4:2-6,adjusts the water content of a mixture to 25-40% by adding water, and finally places a material to be fermented in a sealed package for fermenting for 18-36 hours to obtain a pre-digestion aquatic feed. The pre-digestion method can maximize the functions of detoxifying and antagonizing pathogenic bacteria of a functional microbial feed;the fermentation of the method is basically not limited by an environmental temperature, the equipment investment is small, the operation is simple, and the process is stable. The application of the methodto tilapia culture can effectively improve the growth performance of the tilapia and the ability to resist streptococcal infection, increase the survival rate after infection of thebacteria, and be a pre-digestion treatment technology for the aquatic feed before feeding which is worthy of popularization and application.

Description

technical field [0001] The invention belongs to the technical field of feed processing, and in particular relates to a pre-digestion method for aquatic feed and its product and application. Background technique [0002] With the development of the aquaculture industry towards scale and intensification, feed manufacturers and aquaculture units are doing everything possible to find new cheap feed materials in order to reduce the cost of feed for the sake of economic benefits. The sources of these raw materials are complex and the quality is uneven, especially the safety and quality cannot be guaranteed. Non-feed grade mineral raw materials, non-detoxified cake feed, industrial waste and other plant raw materials without disinfection are added to the feed without testing, causing hidden dangers to the safety of the feed. Disease outbreaks and the resulting drug abuse and product safety issues have seriously threatened the healthy development of the aquaculture industry. [00...
