Problems solved by technology

(2) The protein content of the feed is too high or too low, or the protein content is appropriate but the essential amino acids in it are unbalanced (such as insufficient methionine), resulting in excess protein being converted into fat and deposited in the liver, or fat accumulation due to an imbalance in the ratio of energy and nitrogen
(4) Due to the lack or deficiency of anti-adipogenic factors such as choline, bile acid, carnitine, betaine, and phospholipids, it affects liver cell fat transport or transmission dysfunction, resulting in accumulation
In actual production, the above 2 or 3 substances are generally added at the same time for control, but the effect cannot achieve the expected purpose; or the growth of fish is affected due to excessive addition

Embodiment 1

[0024] Prevention method of fatty liver of snakehead fish in grow-out period

[0025] Use "Kesheng" brand 4# black snakehead puffed compound pellet feed produced by Zhejiang Kesheng Feed Co., Ltd. as the base feed, and add the additive of the present invention, be mixed with in the pellet feed per kilogram: 750 milligrams of choline chloride , bile acid 250 mg, carnitine 200 mg, betaine 3000 mg, phospholipids 12 grams. The pellet feed contains 42% crude protein, 8.0% crude fat, 2.8% lysine, and 1.3% methionine+cystine.

Embodiment 2

[0027] Prevention method of fatty liver of grass carp in growing period

[0028] Use "Kesheng" brand 3# grass carp puffed compound pellet feed produced by Zhejiang Kesheng Feed Co., Ltd. as matrix feed, and add the additive of the present invention, be mixed with in the pellet feed per kilogram: 2500 milligrams of choline chloride, Bile acid 100mg, carnitine 50mg, betaine 1000mg, phospholipid 6g. The pellet feed contains 28% crude protein, 4.5% crude fat, 1.5% lysine, and 0.8% methionine+cystine.

Embodiment 3

[0030] Prevention method of fatty liver of soft-shelled soft-shelled turtle in growing period

[0031] Use " Ke Sheng " brand T31 soft-shelled turtle compound powder feed produced by Zhejiang Ke Sheng Feed Co., Ltd. as matrix feed, and add additive of the present invention, be mixed with in every kilogram of powder feed and contain: choline chloride 1500 milligrams, Bile acid 150mg, carnitine 100mg, betaine 2000mg, phospholipid 6g. The powdered feed contains 43% crude protein, 5% crude fat, 3.0% lysine, and 1.3% methionine+cystine. Before feeding, add 25%-50% water to prepare pellets and feed them to soft-shelled turtles.

[0032]Application effect: taking the addition of choline chloride as the basis for comparison, the fat content in liver decreased by 42% after using the technical product of the invention for snakehead squid with a body weight of 850-900 grams and a body length of 42-43 centimeters. Adding 2% phospholipids in the pellet feed can reduce the fat content in ...

Abstract

The invention provides a feed additive, feed and preparation method thereof for preventing nutritional fatty liver of fish. Optimized compound of choline chloride, bile acid, carnitine, betaine and phospholipids is added into pellet feed for feeding fish, which can obviously reduce the settlement of fat in liver of fish caused by nutrient induction, avoid the generation of fatty liver diseases and promote the healthy growth of fish.

Description

technical field [0001] The invention relates to the technical field of regulating fish nutrient metabolism, in particular, the invention relates to a feed additive for preventing nutritional fatty liver of fish, feed and a preparation method thereof. Background technique [0002] In the past ten years, my country's fish farming industry has rapidly developed from an extensive farming model to an intensive high-density farming model, but research on basic theories and applied technologies in terms of fish nutrition, physiology, pathology and ecology has obviously lagged behind the development of the industry . There is a lack of corresponding scientific and technological support in fish farming. For example, in carnivorous fish farming, it is common to use fresh feed fish to strengthen feeding to promote fish growth, and excessive use of drugs for diseases occurs; Deteriorated feed is more common in various fish farming, leading to metabolic dysfunction of the fish body, dama...
