Embodiment 1
[0016] Use pigskin or fish skin as the gelatinous material, and make 2 kg of artificial egg gelatin membrane each time.
[0017] (1) 400g of degreased pork skin, 100g of fish skin, wash, add water and boil for 1-2 hours according to the water ratio for cooking edible skin jelly, when the soup feels thick, remove the pig skin and fish skin, and put the remaining skin The frozen liquid is stored in a wide-mouth container and left to cool. ℃
[0018] (2) When the skin jelly is cooled to a water temperature of 40-50°C, add 0.4g of vitamins for fish, 4g of organic trace elements for fish, 20g of yeast culture, 8g of Bacillus, 2g of photosynthetic bacteria, 10g of lactic acid bacteria, and Xylose 0.4g, lysine 2g, methionine 1g, glutamic acid 1g, betaine 2g, cooked soybean powder 100g, fish meal 100g, cool to room temperature.
[0019] According to different functions and uses, Chinese herbal medicines or other disease-preventing drugs or other functional additives can be added.
...
Embodiment 2
[0022] (1) Take 16g of edible gum and 2000g of water. Add the rubber powder into the water, heat and stir, so that the water temperature is 40-50°C, and the edible glue is completely dissolved.
[0023] (2) Add 0.4g of vitamins for fish, 4g of organic trace elements for fish, 20g of yeast culture, 8g of bacillus, 2g of photosynthetic bacteria, 10g of lactic acid bacteria, 0.4g of xylooligosaccharides, and lysine into the glue. 2g, methionine 1g, glutamic acid 1g, betaine 2g, cooked soybean powder 100g, fish meal 100g, cool to room temperature and freeze.
[0024] (3) Use a blade to cut the jelly with a thickness of less than 1cm and an area of 10cm 2 Frozen slices of the skin can be placed in water to float for tadpoles to feed on. The amount of feeding is 2%-4% of the total body weight of tadpoles each time.

Abstract
The invention discloses an artificial wood frog egg jelly membrane, which belongs to the technical field of agriculture, is used for wood frog culture and solves the problems of limited egg jelly membrane quantity, non-uniform tadpole ingestion, irregular development, disease liability, high mortality rate and non-vigorous physique in the conventional wood frog culture and incomplete function, unpalatable taste, difficult digestion and absorption, easy pollution of water and the like when tadpoles are fed by common artificial powdery feed and granular feed. Jellies consisting of edible gum, water and nutrients are sliced for feeding, wherein the variety and the using amount of the nutrients can be flexibly selected in common animal raising nutrients. The artificial wood frog egg jelly membrane has the advantages that: an artificial tadpole feed, which simulates the nature, has complete nutrition, is easily eaten by the tadpoles, promotes the growth and development of the tadpoles and is convenient to use, is obtained; the risks of non-uniform tadpole ingestion, irregular development, disease liability and high mortality rate caused by insufficient egg jelly membrane quantity of the tadpoles are eliminated; and the artificial wood frog egg jelly membrane is convenient to use, and does not pollute the water.
Description
technical field [0001] The invention belongs to the technical field of aquaculture, and in particular relates to an artificial breeding of forest frogs. Background technique [0002] As food or medicinal material, wood frog has obvious health care functions. Due to the scarcity of wild wood frog resources and the requirements of environmental protection, culling of wild wood frog has been gradually banned. Due to the high economic value of forest frogs, some people have tried to raise them artificially. Since the current technologies such as feed ingredients, feeding methods, breeding environment, and disease prevention and control for each stage of forest frog growth are still being explored, the cultivation of forest frogs Rana has a low survival rate and slow growth, and very few of them have succeeded in breeding and achieved corresponding economic benefits. [0003] The growth stages of Rana tadpoles are divided into ① early stage of tadpoles: 1 to 7 days, and feed on ...
