Collection method of selenium-rich toad-ecdysis

Abstract

The invention provides a method for collecting selenium enriched toad skins. A toad culture stage comprises the following steps: adding the fodder with the high selenium content 5 to 7 days after the tadpole period, and culturing phycophyta with the high selenium content in the tadpole pond; feeding the bait with the high selenium content and matched fodder in the child toad period; and applying selenium enriched fertilizer to the terrestrial soil of the adult toad pond according to the dosage of 0.4 to 0.6 kg/hm, planting farm crops or vegetables, and feeding artificially cultured bait. A toad skin collecting stage comprises the following steps: adding selenium enriched yeast into the water of an ecdysis pond so as to prevent the selenium contained by the toad from losing; drying the toad skin to the water content less than or equal to 5 percent; and packaging the toad skin into bags after the disinfection through ultraviolet rays so as to obtain the selenium enriched toad skin. The method adds the selenium enriched bait and provides a selenium enriched growing environment in the toad culture process from the child toad to the adult toad, thereby making the toad enriching selenium, and ensuring no loss of selenium in the ecdysis process. Therefore, the toad skin has the high selenium content. The method remarkably improves the medical and functional value of the toad skin.

Description

technical field [0001] The invention relates to a method for collecting selenium-enriched toad clothing. Background technique [0002] Toad is a wild animal with high medicinal value. It has been recorded in famous medical works such as "Compendium of Materia Medica" compiled by Li Shizhen in the Ming Dynasty. The traditional method is to use dried toad (dried body of toad with internal organs removed) and toad venom (dried product of milky white liquid obtained by squeezing the ear gland and skin gland of toad) as medicine. But in order to obtain dried toads, the toads must be killed. This method of obtaining drug sources is undoubtedly killing chickens and extracting eggs, and is also not conducive to the protection of wild animals and the maintenance of ecological balance. The collection of toad venom is more difficult, and the yield is also very low. [0003] The toad coat is the cuticle membrane that the toad naturally sheds. Sun Simiao said: "Toad sloughs (clothes),...
