Fully-cooked granulated feed for greenhouse breeding of soft-shelled turtles and preparation method of feed

Abstract

The invention discloses fully-cooked granulated feed for greenhouse breeding of soft-shelled turtles and a preparation method of the feed. The feed is prepared from raw materials in parts by weight as follows: fish meal, fermented soybean meal, fermented sunflower seed meal, extruded soybeans, blue-green algae, glycine betaine, beta-glucan, pawpaws, vital gluten, fish oil, monocalcium phosphate, methionine, composite vitamins, composite minerals and a traditional Chinese medicine preparation. Compared with the prior art, the feed has the advantages as follows: the matching ratio of amino acid to protein raw materials is balanced, the content of crude protein in the feed is increased, the crude protein and other raw materials in the feed are matched and have a synergistic function, the feed amount of nitrogen and phosphorus is reduced, and accordingly, loss of nitrogen and phosphorus is reduced; livers of the bred soft-shelled turtles are small and bear little load, the disease resistance is higher, antibiotics are avoided, the breeding cost is saved, and the body immunity is activated by generating non-specific immunoregulation factors.

Description

technical field [0001] The invention belongs to the technical field of aquaculture, and in particular relates to a fully-matured pellet feed for soft-shelled turtle culture in greenhouse and a preparation method thereof. Background technique [0002] Soft-shelled turtle is tender and delicious, with high collagen content, and has high edible and medicinal value. Through the practice of various breeding methods, greenhouse farming has become the choice of many farmers. In greenhouse farming, maintaining the ecosystem of soft-shelled turtles has become the most important. One of the key links, maintaining the stability of the ecosystem depends on the balance of energy and material input to the system. In the breeding system, the carbon and nitrogen brought in by the feed constitute the main material and energy factors, and the artificially charged dissolved oxygen It is another important substance. In the greenhouse culture of soft-shelled turtles, due to the inability to incr...

[0002] Soft-shelled turtle meat is tender and delicious, with high collagen content and high edible and medicinal value. Through the practice of various farming methods, greenhouse farming has become the choice of many farmers. In greenhouse farming, maintaining the ecosystem of soft-shelled turtles has become the most important One of the key links, maintaining the stability of the ecosystem depends on the balance of energy and material input into the system. In the breeding system, the carbon and nitrogen brought in by the feed constitute the main material and energy factors, and the dissolved oxygen artificially charged It is another important substance. In the greenhouse culture of soft-shelled turtles, due to the inability to naturally increase dissolved oxygen and the lack of a storage mechanism for nitrogen and phosphorus, the entire ecosystem is more unstable than the outdoor environment. Once the carbon-nitrogen ratio Imbalance, the ecological environment will also seriously deteriorate, the main manifestations are: the reduction of beneficial microorganisms, the proliferation of harmful microorganisms, the prone to bacterial diseases, the slow decomposition of a large amount of feces and residual bait, and the accumulation of ammonia nitrogen and nitrous nitrogen, which is easy for soft-shelled turtles cause poisoning, the function of the feed on the market is mostly to supplement and balance the nutrients required for the growth of soft-shelled turtles, and the ecosystem of soft-shelled turtles in greenhouses is mostly regulated by water quality regulators, because water quality regulation usually has a lag, so the weight of soft-shelled turtle livers Relatively large, toxins are likely to remain in the liver, and the digestive function of the soft-shelled turtle's intestines is poor, resulting in poor quality of soft-shelled turtle meat and high breeding costs, which affect the development of soft-shelled turtle farming
