Problems solved by technology

The composition of the additives is still under exploration. The general additives mainly include brewer’s yeast, immune polysaccharides, and multivitamins. Although adding the above-mentioned additives to the feed can improve the phenomenon of aging, the effect is still unsatisfactory. Therefore, it is necessary to Continue to explore and find a feed additive that can effectively improve abalone's physique, enhance abalone's immunity, metabolism and digestion

Embodiment 1

[0017] Thaw the collected fresh sea squirts or frozen sea squirts, drain the sea water, rinse with fresh water, drain the water, and collect the individuals. Crush the collected Ciona with a pulverizer, filter it with gauze, add appropriate amount of pure water and homogenize it with a digital display high-speed dispersing homogenizer, adjust the pH to 6.5, add 0.1% compound protease for enzymatic hydrolysis, and inactivate the enzyme at 100°C, 4500r / min After centrifuging for 30 min, the supernatant was taken to obtain Ciona polypeptide extract, wherein the determined polypeptide content was 1.6%.

[0018] Add probiotics and multivitamins to the sea squirt polypeptide extract, the probiotics are Bacillus, and the ratio of the multivitamins is vitamin E:vitamin A:vitamin B2:vitamin B=2:2:1:1; the weight percentage of the three 80% of ascidian polypeptide extract, 16% of probiotics, and 4% of multivitamins are used to make abalone feed compound additives.

[0019] How to use: ...

Embodiment 2

[0021] The preparation method of the sea squirt polypeptide extract in this example is consistent with the steps in Example 1, the amount of compound protease added during enzymatic hydrolysis is 0.2%, and the polypeptide content in the obtained extract is 1.8%.

[0022] Add probiotics and multivitamins to the polypeptide extract. The probiotics are used in combination with Bacillus aquaticus and plant lactic acid bacteria. The ratio of the two is 2:1. The proportion of each component in the multivitamin is vitamin E: vitamin A: vitamin B2: Vitamin B=2:2:1:1; the percentage by weight of the three is 85% of ascidian polypeptide extract, 12% of probiotics, and 3% of multivitamin, and it is made into abalone feed compound additive.

[0023] How to use: Mix the above-mentioned compound additive with abalone seedling feed, the mixing ratio is: abalone seedling feed: compound additive = 10:1, after mixing evenly, the feed is moist and not agglomerated, loose, ready for use; feed ever...

Embodiment 3

[0031] The preparation method of the sea squirt polypeptide extract in this example is consistent with the steps in Example 1, the amount of compound protease added during enzymolysis is 0.3%, and the polypeptide content in the obtained extract is 1.96%.

[0032] Add probiotics and multivitamins to the polypeptide extract. The probiotics use plant lactic acid bacteria. The proportion of each component in the multivitamins is vitamin E: vitamin A: vitamin B2: vitamin B=2:2:1:1; the ratio of the three The percentage by weight is 82.5% of polypeptide extract, 14% of probiotics, and 3.5% of multivitamins, and is made into a compound additive for abalone feed.

[0033] How to use: Mix the above-mentioned compound additive with abalone seedling feed, the mixing ratio is: abalone seedling feed: compound additive = 8:1, after mixing evenly, the feed will be moist and non-caking, loose, and ready for use; feed every evening Feed once, and the feeding amount accounts for 0.5% of the wei...

Abstract

The invention relates to a compound feed additive for aquatic product breeding as well as a preparation and use method of the additive. The invention aims to explore and prepare the compound feed additive for abalone breeding by utilizing the anti-oxidation, anti-tumor, and immunity-improving functions of ciona intestinalis polypeptides, and the metabolic capability and disease resistance improving functions of probiotics. The feed compound additive is characterized in that the feed compound additive is formed by mixing the following components in percentages by weight: 80-85% of a ciona intestinalis polypeptide extraction liquid, 12-16% of the probiotics and 3-4% of multivitamins. The feed compound additive for the abalones provided by the invention has no adverse effect on the growth ofthe abalones, feeding tests show that after the compound additive is added into the feed, the abalone growth can be effectively promoted, the abalone own immunity can be improved, and the problem of young slow-growth poor-quality and low-immunity abalones can be completely solved.

Description

【Technical field】 [0001] The invention relates to a compound feed additive for aquatic product cultivation and its production and use methods. 【Background technique】 [0002] Abalone has unique feeding habits and breeding characteristics. The feed is mainly seaweed, and a large amount of algae is consumed every year. However, the growth of seaweed is greatly affected by seasonality, resulting in insufficient nutrition of seaweed and low feed conversion efficiency, which greatly affects the breeding effect of abalone. The lack of seaweed nutrition will lead to slow growth, poor quality and low immunity of abalone. We call this kind of abalone fry old man seedlings. Its essence is caused by the reduction of abalone's own immunity, metabolism and digestion. For solving the above problems, the main measures taken at present are the method of adding additives in the abalone feed to improve the phenomenon of old abalone seedlings. The composition of the additives is still under...
