Embodiment 1

[0017] A method for preparing a feed for promoting hairy crab moulting, comprising the following steps:

[0018] 1) Take 120 parts of fresh perch viscera and homogenate into the container, add 100 parts of distilled water, stir in the water bath and raise the temperature to 35°C, add 8% potassium hydroxide solution to adjust the pH to 8.2, continue to stir and heat up to 55°C, and keep warm for 15 minutes , add 5 parts of potassium chloride and stir to dissolve, salt out for 20 minutes and centrifuge while hot to separate the crude fish oil; siphon the crude fish oil and wash it with hot water 3 times, centrifuge while it is hot, take the upper liquid, and dry it in a vacuum oven to get the fish viscera Oil; 2) Weigh 100 parts of fish viscera oil, 150 parts of distilled water, and 0.05 parts of vitamin E, mix them evenly in a closed container, place the reaction container in an ultrasonic instrument, heat it to 70°C and keep it, and continue to supply oxygen for 10 minutes , t...

Embodiment 2

[0020] A method for preparing a feed for promoting hairy crab moulting, comprising the following steps:

[0021] 1) Extract fish viscera oil: Take 130 parts of fresh perch viscera homogenate into a container, add 150 parts of distilled water, stir in a water bath and raise the temperature to 36°C, add 10% potassium hydroxide solution to adjust the pH to 8.4, continue to stir and heat up to 60°C ℃, keep warm for 25 minutes, add 7 parts of potassium chloride and stir to dissolve, salt out for 30 minutes and centrifuge while hot to separate the crude fish oil; siphon the crude fish oil and wash it with hot water for 5 times, centrifuge while it is hot, take the upper liquid, and use a vacuum drying oven Fish viscera oil can be obtained by drying; fish viscera oil is very suitable as a nutrient substance for hairy crab feed, and this method has a high yield of fish oil and is easy to operate. Waste water and waste residue can be made into green and efficient fertilizers for complet...

Embodiment 3

[0028] A method for preparing feed for promoting hairy crab shell moulting, comprising: extracting fish visceral oil, modifying fish oil, fermenting fish meal, fermenting cottonseed meal, and compounding, specifically including the following steps:

[0029] Extract fish viscera oil: Take 130 parts of fresh perch viscera homogenate into the container, add 130 parts of distilled water, stir in the water bath and raise the temperature to 35°C, add 9% potassium hydroxide solution to adjust the pH to 8.3, continue to stir and heat up to 58°C, Keep warm for 20 minutes, add 6 parts of potassium chloride and stir to dissolve, salt out for 25 minutes and then centrifuge while hot to separate the crude fish oil; siphon the crude fish oil and wash it with hot water 4 times, centrifuge while it is hot, take the upper liquid, and dry it in a vacuum oven. Obtain fish viscera oil; fish viscera oil is very suitable as a nutrient substance for hairy crab feed, and this method has a high yield o...

Abstract

The invention discloses a preparation method of feed capable of promoting hairy crabs to change shells. The preparation method comprises the following steps: extraction of fish viscera oil, modification of fish oil, fermentation of fishmeal, fermentation of cottonseed meal and compounding. The feed capable of promoting the hairy crabs to change shells is composed of the following materials in parts by weight: 20-25 parts of modified fish oil, 15-20 parts of fermented fishmeal, 40-50 parts of fermented bean meal, 10-12 parts of flour, 2-5 parts of table salt, 0.2-0.3 part of ecdysterone, 0.2-0.3 part of squid cream, 3-5 parts of shrimp meal powder, 0.5-1.0 part of carboxymethyl cellulose, 3-5 parts of compound premix, 0.005-0.006 part of astaxanthin and 0.005-0.006 part of canthaxanthin. The feed capable of promoting the hairy crabs to change shells has the beneficial effects: the feed has stronger oxidation resistance, can clear away excessive free radicals from the bodies of the hairycrabs, improves the immunity and anti-stress ability of the hairy crabs, improves the constitutions and vitality of the hairy crabs in a shell-changing period and enables the hairy crabs to get through the shell-changing period safely.

Description

technical field [0001] The invention relates to the field of preparation of hairy crab feed, in particular to a preparation method of feed for promoting hairy crab moulting. technical background [0002] Eriocheir sinensis is an economic crab, also known as river crab, hairy crab, clear water crab, and hairy crab. It is a famous delicacy in China. Its chelicerae are used for feeding and fighting against enemies, and the inner and outer edges of the palm are densely covered with hairs, hence the name mitten crab. Omnivorous animals, fish, shrimp, snails, mussels, worms, earthworms, insects and their larvae can be used as animal bait for hairy crabs. Crabs contain more vitamin A, which is helpful for skin keratinization; it can also supplement calcium for children's rickets and old people's osteoporosis. It is widely distributed in lakes along the north and south coasts in China, among which the Yangtze River system has the largest output and extremely delicious taste. Eri...
