Problems solved by technology

The existing aquatic crab feed mostly uses inorganic selenium addition technology with poor safety and high toxicity and side effects, which also poses a great risk to the environment
At present, corn and wheat are one of the main feeds for river crab breeding, which cannot be used during the period of detaining crabs, and crushing corn or wheat particles will cause a lot of losses, and the ingredients are relatively simple, which is difficult to meet the nutritional needs of river crabs.

Embodiment 1

[0007] Embodiment 1: the production method of novel river crab feed, comprising fish meal 15%, flour 20%, soybean meal 26%, food attractant 8%, squid meal 5%, shrimp shell powder 10%, immune polysaccharide 4%, shelling factor 6 % and vitamin 6%, said percentages are percentages by weight. This example is granulated by ultra-fine pulverization and post-ripening process. When in use, firstly, it can be directly fed alone. Under normal circumstances, it is generally not necessary to add other materials; secondly, it can be fed according to the weather, water temperature, water quality, and growing season. , breeding density and climate conditions, adjust the feeding amount, set the feeding frequency reasonably, reduce the feeding amount when a large number of crabs moult, and increase the feeding amount after one day of moulting; finally, do not change the brand frequently when using , It takes 3 to 4 days for the same brand to change the feed at different stages.

Embodiment 2

[0008] Embodiment 2: the production method of novel crab feed, comprising fish meal 10%, flour 25%, soybean meal 30%, food attractant 7%, squid meal 4%, shrimp shell powder 8%, immune polysaccharide 4%, shelling factor 6 % and vitamin 6%, said percentages are percentages by weight. This embodiment adopts superfine pulverization and post-aging process to granulate, and the others are the same as the first embodiment.

Embodiment 3

[0009] Embodiment three: the production method of novel river crab feed, comprising fish meal 12%, flour 25%, soybean meal 28%, food attractant 7%, squid meal 5%, shrimp shell powder 9%, immune polysaccharide 4%, shelling factor 5 % and vitamin 5%, said percentages are percentages by weight. This embodiment adopts superfine pulverization and post-aging process to granulate, and the others are the same as the first embodiment.

Abstract

The invention relates to the technical field of feed production methods, and particularly relates to a production method of a novel river crab feed, comprising the following components by weight percent: 15-20% of fish meal, 20-25% of flour, 25-30% of bean pulp, 6-8% of an attractant, 4-8% of squid powder, 7-10% of shrimp shell meal, 3-4% of immune polysaccharide, 5-6% of shelling element, and 5-6% of vitamin. According to the physiological function and nutritional requirement of the river crab in different growth stages, quality raw materials are selected, various nutrient elements are added in a balanced way, the raw material ratio is scientific, and thus the novel river crab feed has the characteristics of being comprehensive in nutrients and enhancing the immunity and effectively promotes the healthy growth of the river crab. Furthermore, the feed has good adhesiveness and is high in stability in water and is not easy to scatter, thus effectively reducing loss of the feed in water, reducing waste and providing good water environment for the river crab. Aiming at the ingestion characteristics of the river crab, the feed is added with natural attractants, thus having the advantages of being good in palatability, strong in attracting capability and quick to digest, and improving the delivery standard and uniformity.

Description

technical field [0001] The invention relates to the technical field of feed production methods, in particular to a production method of novel river crab feed. Background technique [0002] River crabs are endemic to our country, delicious and nutritious, and are famous all over the world. In the existing aquatic crab feed, the inorganic selenium addition technology with poor safety and high toxic and side effects is mostly used, which also causes great risks to the environment. At present, corn and wheat are one of the main feeds for river crab breeding, and they cannot be used during the period of detaining crabs, and crushing corn or wheat particles will cause a lot of losses, and the ingredients are relatively simple, which is difficult to meet the nutritional needs of river crabs. Contents of the invention [0003] The purpose of the present invention is to provide a production method of a novel river crab feed with comprehensive nutrition, scientific formula, good vi...
