Problems solved by technology

[0007] The purpose of the present invention is to address the deficiencies in the prior art, to provide a compound feed with balanced nutritional ratio, good palatability, prevention of nutritional fatty liver of soft-shelled turtles, enhancement of immunity, and effective improvement of the meat quality of cultured soft-shelled turtles, so as to overcome the problems in the prior art. The nutrient composition of the feed used is unbalanced, which makes the meat of the soft-shelled turtle rough and boring, and causes a large amount of fat to be deposited in the liver.

Embodiment 1

[0028] A compound feed for improving the meat quality of cultured soft-shelled turtles, including the following components: 32% white fish meal, 15% grass insects, 15% offal left after processing Echinacea monoringensis, 4% mussels, 4% barnacles, 5% Compound amino acid, 2% additive for preventing fatty liver, 2.5% vitamin premix and 0.5% astaxanthin; wherein, the mass ratio of essential amino acid and flavor amino acid is 2:1; parts by weight of each component of additive for preventing fatty liver As follows: 23 parts of algae polysaccharides, 20 parts of poplar flower extract, 8 parts of taurine, 37 parts of phospholipids, and 13 parts of choline chloride.

[0029] The preparation method of the compound feed that improves the meat quality of cultured soft-shelled turtle, concrete steps are as follows:

[0030] 1) Centipede algae polysaccharide: dry, crush and sieve Centipede algae, add 4-6 times distilled water, microwave pretreatment for 90-150s, add absolute ethanol, so th...

Embodiment 2

[0039] Content verification of flavor amino acids and unsaturated fatty acids in meat soft-shelled turtle muscle

[0040] Thirty-six soft-shelled soft-shelled turtles with similar body weight and body mass (265.59) g were randomly divided into two groups, and each group was fed with the diet of the experimental group and the diet of the control group. The test aquarium is 120cm×60cm×55cm, and the water surface height is 15cm. Change the water once every other day, the water temperature is (25±1)℃, and the sunlight is illuminated for 10 hours every day. Feed 3-5% of the body weight every day, the feeding time is 10:00 and 16:00 full feeding, adjust once a week, after continuous feeding for 40 minutes, collect the residual bait and dry it, calculate the actual feeding amount . The trial period is three months. The contents of flavor amino acids and unsaturated fatty acids in soft-shelled turtle muscles were determined, and the results are shown in Table 1.

[0041] The mass ...

Embodiment 3

[0047] The mass increase rate and feed coefficient verification of meat soft-shelled turtle are shown in Table 2.

[0048] Mass increase rate / %=(m2-m1) / m1×100%;

[0049] Feed coefficient = m3 / (m2-m1);

[0050] In the formula, m1 is the initial average mass (g), m2 is the final average mass (g), and m3 is the ingested mass (g).

Abstract

The invention discloses a compound feed for increasing the meat quality of cultured meat turtles. The compound feed is prepared from white fish powder, tylorrhynchus heterochaetus, residual entrails generated after treatment of urechis unicinctus, mussel, barnacle, fat, essential amino acid, delicious amino acid and a fatty liver prevention additive, wherein the fatty liver prevention additive isprepared from gralteloupia ramosissima polysaccharide, a poplar flower extract, taurine, phospholipid and choline chloride. The invention also discloses a preparation method for increasing the meat quality of the meat turtles. The compound feed disclosed by the invention has the beneficial effects that tylorrhynchus heterochaetus powder and the residual entrails generated after the treatment of the urechis unicinctus are used for replacing the white fish powder, grease which is rich in unsaturated fatty acid is used as a fat source, mineral elements and feed adhesives are provided by utilizingthe mussel and the barnacle, the fatty liver prevention additive is added, the components are complete, the nutrition is balanced, the palatability is good, decomposition, digestion and absorption ofthe fat are promoted, fatty liver disease is avoided, health growth of the meat turtles is promoted, the muscle quality is improved, and the culture benefit is increased.

Description

technical field [0001] The invention relates to the technical field of aquatic feed, in particular to a compound feed for improving the meat quality of cultured soft-shelled turtles. Background technique [0002] Meat soft-shelled turtles, commonly known as "turtle", "cuckoo", etc., have high economic and medicinal value. Soft-shelled soft-shelled turtles in my country are mainly soft-shelled soft-shelled turtles, a carnivorous reptile that often inhabits freshwater waters with sandy and muddy bottoms. It usually feeds on fish and shrimp, and also eats bottom-dwelling molluscs and crustaceans. The Chinese soft-shelled turtle has a protein requirement as high as 50%, especially fishmeal, which is added in a relatively high amount in the soft-shelled soft-shelled turtle compound feed. In recent years, due to the shortage of fishmeal resources in the world, the development of Chinese soft-shelled turtle breeding industry has been further restrained. Therefore, finding protein...
