A kind of extruded feed for juvenile soft-shelled turtle and preparation method thereof

Abstract

The invention relates to an expanded feed for young soft-shelled turtles and a preparation method thereof. The expanded feed comprises the following raw materials in part by weight: 30-40 parts of white fish powder, 19-30 parts of red fish powder, 18-25 parts of flour, 2-5 parts of beer yeast, 2-8 parts of fermented bean meal, 2-7 parts of expanded soybean, 1-2 parts of phagostimulant, namely fish oil, 1-1.5 parts of composite vitamin, 0.5-1.5 parts of minerals, 1-2 parts of monocalcium phosphate, 0.3 part of antioxidant and 0.1 part of mould inhibitor. Compared with the prior art, the expanded feed has the beneficial effects that the absorption and utilization conditions of nutrient substances are fully improved, the waste of feeds can be effectively reduced, the breeding management cost is reduced, and the pollution to a water body is reduced to the maximum extent; the expanded feed is high in water stability; the intake condition of animals is easy to observe; and the ecological environment is effectively optimized and protected.

Description

technical field [0001] The invention relates to the technical field of feed, in particular to an extruded feed for juvenile soft-shelled turtles and a preparation method thereof. Background technique [0002] Soft-shelled turtles are also known as soft-shelled turtles, water fish, turtles, foot fish, etc., and belong to the vertebrate phylum, reptiles, aarches, turtle orders, and soft-shelled turtles in zoology, and their scientific name is Trong x Sinensis. Soft-shelled turtle is a traditional valuable nourishing aquatic product. It not only has high nutritional value, but also has very high medicinal value, and has received great attention at home and abroad. In recent years, with the continuous improvement of people's living standards, the demand for soft-shelled turtles is also increasing, but wild resources are extremely limited, so the development of artificial and factory farming of soft-shelled turtles has become the general trend. [0003] Feed is the carrier of nu...

AI Technical Summary

Problems solved by technology

At present, soft-shelled turtle compound feeds are all powdery compound feeds. A large number of facts have proved that powdery compound feeds have poor stability in water and are easy to lose and pollute water quality; thus resulting in poor breeding environment and providing conditions for the growth and reproduction of pathogenic bacteria, resulting in soft-shelled turtles. In order to reduce economic losses, farmers will add antibiotics or even some prohibited drugs to feed for a long time to artificially improve their disease resistance and immunity, resulting in serious drug residues in commercial soft-shelled turtles.

At the same time, the powdered material needs secondary processing before feeding, which is inconvenient to use

The currently used compound feed for soft-shelled turtles is mainly white fishmeal, which is expensive. The fishmeal used is basically imported high-grade fishmeal, which is severely restricted by the supply of goods.

At present, the supply of fishmeal resources is seriously insufficient, which has become a restrictive factor for the further development of aquaculture

At the same time, as the market price of soft-shelled turtles continues to decline, the cost of breeding has become one of the important factors restricting the development of soft-shelled turtle farming.
