[0031] A kind of feed additive that improves the molting rate in crab culture includes: calcium lactate, bile acid, trace element, quicklime, bacillus, biological fertilizer, organic acid, Trichosanthes root, calcium dihydrogen phosphate, vitamin; Wherein, the lactic acid Calcium, the bile acid, the trace element, the quicklime, the bacillus, the biological fertilizer, the organic acid, the Trichosanthes root, the calcium dihydrogen phosphate, and the vitamin are as follows Composition in parts by weight: 7-15 parts of the calcium lactate, 5-9 parts of the bile acid, 4-11 parts of the trace element, 11-18 parts of the quicklime, 9-13 parts of the bacillus, the 6-8 parts of biological fertilizer, 4-9 parts of the organic acid, 10-14 parts of the Trichosanthes root, 5-8 parts of the calcium dihydrogen phosphate, and 4-7 parts of the vitamin.
[0032] It consists of the following parts by weight: 7 parts of the calcium lactate, 5 parts of the bile acid, 4 parts of the trace eleme...

[0044] see figure 1 , figure 2 , image 3 , Figure 4 , based on the feed additive and its processing technology for improving the molting rate in crab cultivation provided in the first embodiment of the application, the second embodiment of the application proposes another feed additive and a feed additive for improving the molting rate in crab cultivation its processing technology. The second embodiment is only a preferred mode of the first embodiment, and the implementation of the second embodiment will not affect the independent implementation of the first embodiment.
[0045] Concretely, the difference between the feed additive and its processing technology for improving the molting rate in crab cultivation provided by the second embodiment of the present application is that the feed additive and its processing technology for improving the molting rate in crab cultivation also include the use of In the frying assembly 1 in the S4 step, the frying assembly 1 includes ...

Abstract
The invention provides a feed additive for improving the shelling rate in crab breeding and a processing technology of the feed additive. Comprising calcium lactate, bile acid and trace elements. According to the feed additive capable of increasing the shelling rate in crab breeding and the processing technology of the feed additive, the calcium lactate, the bile acid, the trace elements, the quick lime, the bacillus, the biological fertilizer, the organic acid, the trichosanthes kirilowii maxim roots and the like are used as main raw materials, so that crabs can be promoted to recover physique, and shelling hormones required by the crabs are synthesized; the beneficial bacteria can inhibit reproduction and growth of harmful bacteria, reduce diseases, timely degrade and convert organic matters in the pond and promote growth of excellent algae, so that the effect of inhibiting growth of moss can be achieved, and the situation that moss covers the bottom of the crab pond, feed feeding cannot reach the bottom of the pond, and crab ingestion is affected is avoided; meanwhile, the quick lime can improve water quality, increase dissolved oxygen, adjust the pH value of the water body and increase the calcium ion concentration of the water body, and growth of the crabs after shelling is facilitated.
Description
technical field [0001] The invention relates to the technical field of crab cultivation, in particular to a feed additive for improving the molt rate in crab cultivation and a processing technology thereof. Background technique [0002] Crabs belong to the class Molecula, decapod order, and are crustaceans. The body is protected by a hard shell and breathes by gills. In biological taxonomy, it is the same animal as shrimp, lobster, and hermit crab. [0003] Crabs are crustaceans. Every time they grow, they moult. Every time they molt, their weight and volume increase. From young crabs to adult crabs, they molt 5-6 times. When final size and viability are most critical, preparation prior to moulting and management during moulting are therefore critical. [0004] However, the existing crabs are affected by water quality, moss, etc., so that the crabs cannot synthesize or synthesize a small amount of molting hormones, and the crabs may fail to molt. At the same time, the moss ...
