Embodiment 1

[0051] A special feed compound additive for squid, comprising:

[0052] (I) oligosaccharide composition; and / or

[0053] (II) carboxylic acid esters; and

[0054] (Ⅲ) protease complex; the (Ⅲ) protease complex is a protease complex comprising an effective protease mixture obtained by cultivating Hyphomyces lanuginosa. The special feed additives for anglerfish can help to improve the intestinal microbial flora of the anglerfish, promote the regeneration of intestinal villi of the anglerfish, improve the intestinal absorption of target nutrients, maintain the health of the gastrointestinal tract and / or reduce the demand for antibiotics and reduce the cost of breeding process. The abuse of antibiotics in medium can also significantly reduce the feed-to-meat ratio of squid breeding and shorten the breeding cycle. In addition, the above-mentioned protease complex helps to strengthen the immune system of squid, which can significantly reduce the incidence of squid caused by bacteri...

Embodiment 2

[0072] A kind of (I) oligosaccharide composition has following glycosidic bond distribution: have 15mol% α-1,6 glycosidic bond and 12mol% β-2,1 glycosidic bond, and wherein the polymerization degree of 10 dry weight % oligosaccharide composition is 6.

[0073] The (I) oligosaccharide composition includes: isomaltose-lactose-oligosaccharide, lactose-inulin disaccharide-oligosaccharide and inulin disaccharide-isomaltose-oligosaccharide. The application of oligosaccharide composition in the special feed additive or feed for squid has beneficial health effects, which can help reduce fish mortality, improve intestinal microbial flora, improve nutrient absorption, and maintain gastrointestinal tract. Health and / or reduce the need for antibiotics, reduce the abuse of antibiotics in the farming process.

[0074] One (II) carboxylate is lactoyl carboxylate according to formula 1,

[0075] Formula 1: R 1 -COO-[-CH(CH 3 )-COO] 2 -R 2 and its Na salt, glycolyl carboxylate according ...

Embodiment 3

[0091] A special feed compound additive for squid, comprising:

[0092] (I) an oligosaccharide composition; and (II) a carboxylic acid ester; and (III) a protease complex; the (III) protease complex is a protease comprising an effective protease mixture obtained by cultivating Hyphomyces lanuginosa Complex. The special feed additives for anglerfish can help to improve the intestinal microbial flora of the anglerfish, promote the regeneration of intestinal villi of the anglerfish, improve the intestinal absorption of target nutrients, maintain the health of the gastrointestinal tract and / or reduce the demand for antibiotics and reduce the cost of breeding process. The abuse of antibiotics in medium can also significantly reduce the feed-to-meat ratio of squid breeding and shorten the breeding cycle. In addition, the above-mentioned protease complex helps to strengthen the immune system of squid, which can significantly reduce the incidence of squid caused by bacterial pollution...

Abstract

The invention provides a special feed compound additive for squid, which belongs to the technical field of squid breeding, including (I) oligosaccharide composition; and / or (II) carboxylic acid ester; and (III) protease complex; the (III) protease The complex is a protease complex comprising a potent protease mixture obtained by culturing Myces lanuginosa. The invention also provides a special feed for squid containing the basic feed and compound additives for the special feed for squid. The beneficial effects are: the special feed compound additive for squid can improve the intestinal flora of squid and can promote the regeneration of intestinal villi, improve the efficiency of intestinal absorption, maintain the health of gastrointestinal tract and / or reduce the demand for antibiotics, and reduce the Abuse of antibiotics has significantly reduced the morbidity and mortality of goblins.

Description

technical field [0001] The invention belongs to the technical field of squid breeding, and in particular relates to a special feed compound additive for squid. Background technique [0002] The squid belongs to the family Perciformes and has a silver-gray body color. Prolific in the East China Sea Zhoushan Yangmian. The average body length of each fish is 45-55cm, the weight is 500-1000g, and the maximum weight is more than a hundred catties. Distributed in the Bohai Sea, Yellow Sea, East China Sea, South China Sea and other waters. Elongated and flattened body, shallow curved back and abdomen, large individuals can reach more than 10 kg, large and slightly oblique mouth, body covered with ctenoid scales, small scales, rough surface, round scales on the head, 4 jaw holes , The central and medial foramen are arranged in a square shape, without barbels. The outer teeth of the upper jaw and the inner teeth of the lower jaw are enlarged, showing canine shape, and the small t...
