Problems solved by technology

[0005] At present, domestic soft-shelled turtle farming mainly relies on chilled fish bait and soft-shelled soft-shelled turtle feed, which are expensive, cumbersome to operate, and easy to pollute water quality. At the same time, pathogens such as parasites, bacteria and viruses may be introduced, and the unstable quality of soft-shelled turtles also affects soft-shelled turtles. Breeding brings inconvenience
Some other feeds manufactured by existing technology cannot be selected according to the growth and physiological digestion characteristics of soft-shelled turtles, and the production process is also very easy to destroy nutrients, resulting in low utilization rate of these feeds, easy to pollute water quality, and not suitable for large-scale soft-shelled turtles farming

Abstract

The invention discloses a preparation method of a soft-shelled turtle granulated feed. The method comprises the following steps that 1, fish meal, chicken meal, beer yeast, bean pulp, flour and a mineral element mixture are mixed, smashed, blended, puffed and granulated under the temperature of 90-110 DEG C and dried under the temperature of 50-100 DEG C; 2, egg powder, wet sand insects and shrimp mince are mixed, homogenizing is performed through a colloid mill, and then glycine betaine, fish oil and vitamin mixtures are added and subjected to emulsification and homogenizing; 3, under vacuum, the emulsion obtained in the step 2 is sprayed to surfaces of semi-finished dried granules obtained in the step 1 in a vacuumized mode, and the feed is obtained through drying, cooling, smashing, screening, weighing and packaging. The method is suitable for large-scale production, the biological active components of fresh feed raw materials and instable nutrient elements such as fish oil and vitamins in the feed formula can be effectively kept, pathogens in the feed are reduced, the aquatic water quality environment can be improved, the food calling performance and utilizing efficiency of the feed can be improved, and the soft-shelled turtle survival rate and growth performance can be improved.

Description

[0001] Technical field: [0002] The invention relates to the field of feed, in particular to a method for preparing soft-shelled turtle pellet feed. [0003] Background technique: [0004] Soft-shelled turtle, also known as soft-shelled turtle and turtle, is an oviparous amphibian reptile. It is rich in nutrition and can be used as medicine. It contains protein, fat, calcium, iron, animal glue, keratin and multiple vitamins. It is a rare tonic. Breeding seedlings mainly include Chinese soft-shelled turtle seedlings, Japanese soft-shelled turtle seedlings, Chinese soft-shelled turtle seedlings, Thai soft-shelled turtle seedlings, hybrid seedlings, etc. At present, the annual breeding output of soft-shelled turtles in my country is nearly 200,000 tons, with an output value of nearly 10 billion yuan, and has formed a complete industrial chain of brood breeding, seedling cultivation, adult fish breeding and processing and exporting. Soft-shelled turtle farming is mainly distribut...
