Embodiment 1

[0034]A method for preparing a composite additive for preventing intestinal damage to prawns under a low-fish meal and high-soybean meal feed, specifically implemented according to the following steps: Weighing components according to parts by mass: 30 parts of fructooligosaccharides, 7 parts of tributyrin, gluten Aminoamide dipeptide 18 parts, white carbon black 15 parts, defatted rice bran 30 parts. Use the above weighed white carbon black as a carrier to absorb tributyrin; then mix it with the above weighed fructooligosaccharide, glutamine dipeptide and defatted rice bran carrier to prevent prawn intestines from low fishmeal and high soybean meal feed. Composite additive product for road damage.

[0035] The beneficial effects of the present embodiment 1 are illustrated below in conjunction with the experimental results:

Embodiment 2

[0046] A method for preparing a composite additive for preventing intestinal damage to prawns under a low-fish meal and high-soybean meal feed, specifically implemented according to the following steps: Weigh the components according to parts by mass: 25 parts of fructooligosaccharides, 5 parts of tributyrin, gluten 20 parts of aminoamide dipeptide, 10 parts of white carbon black, and 40 parts of defatted rice bran; use the above-mentioned weighed white carbon black as a carrier to adsorb tributyrin; and the defatted rice bran carrier are uniformly mixed to obtain a compound additive product for preventing intestinal damage of prawns under a low-fishmeal-high-soybean meal feed.

Embodiment 3

[0048] A method for preparing a compound additive for preventing intestinal damage to prawns under a low-fish meal and high-soybean meal feed, specifically implemented according to the following steps: Weigh the components according to parts by mass: 25 parts of fructooligosaccharides, 8 parts of tributyrin, gluten 20 parts of aminoamide dipeptide, 16 parts of white carbon black, and 31 parts of defatted rice bran; use the above-mentioned weighed white carbon black as a carrier to adsorb tributyrin; and the defatted rice bran carrier are uniformly mixed to obtain a compound additive product for preventing intestinal damage of prawns under a low-fishmeal-high-soybean meal feed.

Abstract

The invention discloses a composite additive for preventing prawn intestinal injury under the condition of low-fish-meal and high-soybean-meal feed and a preparation method of the composite additive and belongs to the technical field of aquatic feed additives. The composite additive comprises components in parts by mass as follows: 25-30 parts of fructooligosaccharide, 5-10 parts of tributyrin, 15-25 parts of glutamine dipeptide, 10-20 parts of white carbon black and 15-45 parts of defatted rice bran. The invention further discloses the preparation method of the composite additive for preventing the prawn intestinal injury under the condition of the low-fish-meal and high-soybean-meal feed. The composite additive can control breeding of pathogenic bacteria of prawn intestinal tracts under the condition of the low-fish-meal and high-soybean-meal feed, adjusts balance of intestinal flora, repair intestinal mucosa and maintain health of the intestinal mucosa. Besides, the activity of digestive enzyme of the intestinal tracts can be improved, the immune function is activated, and the prawn growth performance and the feed utilization efficiency are improved.

Description

technical field [0001] The invention relates to the technical field of aquatic feed additives, in particular to a composite additive for preventing intestinal damage of prawns under the feed condition of low fish meal and high soybean meal and a preparation method thereof. Background technique [0002] With the rapid development of the aquaculture industry, the demand for fishmeal in aquafeeds is increasing day by day, which makes the global supply of fishmeal increasingly tense, the market competition intensifies, and the price rises. The cost of feed formula is more and more affected by the price of fishmeal. Therefore, vigorously developing high-quality and low-cost aquatic animal feed protein sources is a hot topic for the current aquaculture industry to get rid of difficulties, reduce breeding costs, and improve economic benefits. As a plant-based protein material, soybean meal has become one of the main substitutes for fishmeal in aquatic animal feed due to its high cr...
