Breeding method for improving nutrition value of soft-shelled turtle

Abstract

The invention discloses a breeding method for improving nutrition value of a soft-shelled turtle. The method applies a safe selenium feed with high nutrition value to feed the soft-shelled turtle; nutrition required is provided according to different growth periods of the soft-shelled turtle, thus the method can effectively improve the nutrition balance of the soft-shelled turtle, increase the selenium content of the soft-shelled turtle, enhance the immunity, and promote its growth and development. The selenium feed is prepared from cassava leaf extractive, degreased fish flour, gadus bone flour, chicken flour, fermented soybean meal, extruded soybean, walnut powder, witloof powder, watermelon peel powder, glucose, seaweed meal, monocalcium phosphate, table salt, and crosslinking seleniummethionine.

Description

technical field [0001] The invention relates to the technical field of aquatic animal breeding, in particular to a breeding method for improving the nutritional value of soft-shelled turtles. Background technique [0002] Soft-shelled turtle, scientific name soft-shelled turtle, commonly known as water fish, turtle and tortoise, is a kind of oviparous amphibian reptile. The edge of the carapace is soft and skirt-like, and the color is dark green. The soft-shelled turtle often lives in the mud and sand at the bottom of the water, and likes to eat small animals such as fish and shrimp, as well as melon peels, grasses and grains. The whole body is divided into five parts: head, neck, trunk, limbs and tail. [0003] Turtle is rich in nutrition, containing protein, fat, calcium, iron, copper, animal glue, keratin and multivitamins. Turtle meat contains protein, fat, carbohydrates, ash, magnesium, calcium, iron, phosphorus, vitamin A, vitamin B1, vitamin B2, niacin, thiamine, ri...

Problems solved by technology

[0005] Selenium is an important trace element in the human body. At present, the commonly used selenium supplement methods for the human body mainly include taking sodium selenite, eating selenium salt, etc., but these methods have obvious limitations due to the difficulty in controlling intake and potential toxicity; From the perspective of long-term and safety, it is a safe and effective way to supplement selenium through diet and to make selenium enter the human body through food.

[0006] At present, in order to pursue high yield and high efficiency, some soft-shelled turtle farmers often use high-protein soft-shelled soft-shelled turtle compound feed, excessive baiting, and high-density breeding, resulting in the accumulation of residual bait in the water body and a large amount of excrement substances of soft-shelled turtles, and the nitrogen and phosphorus levels in the breeding water seriously exceed the standard. The concentration of harmful substances such as salt and ammonia is too high, the water quality is seriously polluted, the soft-shelled turtle's physique is severely reduced, its immunity is weakened, and diseases often occur, and the added feed has a single nutritional component, which cannot meet people's needs
