Problems solved by technology

[0010] (e) The production process is very complicated and requires high investment in facility fees, which consumes a lot of time and costs and increases production costs
[0011] As mentioned above, the previous feed additives made mainly of cuttlefish viscera were not suitable for fish farming, especially for the rapid growth of shrimp, due to a large number of problems in the heating and concentration process.

Embodiment 1

[0029] After cleaning the miscellaneous bacteria adhering to the viscera of the raw squid, it is naturally fermented and decomposed at a temperature of 37-40° C. for 6-7 days to generate amino acids, thereby producing the target feed additive. Fat rich in unsaturated fatty acids is not separated so that it is contained in squid guts. These ingredients can promote the fertility of organisms. This method has low economic efficiency and is not suitable for mass production.

Embodiment 2

[0031] A cultured fermentation accelerator is added to raw cuttlefish viscera to accelerate fermentation. Specifically, with the cuttlefish viscera cleaned of miscellaneous bacteria as 100% (weight), add 5-10% (weight) molasses, 10-20% (weight) soybean meal, After heating at a certain temperature for 10 to 15 minutes, the mixture is cooled to 35 to 40° C., and then 7 to 10% (by weight) of compound lactic acid bacteria are added to promote the enzyme reaction and carry out fermentation and decomposition. After about 5 to 7 days, it is sterilized at about 80° C. to manufacture the target feed additive.

[0032] The amount of compound lactic acid bacteria added is not limited to the above, based on squid viscera as 100% (weight), the added amount of compound lactic acid bacteria is 5-20% (weight), preferably 5-15% (weight). The addition amount of the compound lactic acid bacteria in the Example of this invention is the value when the bacteria density|concentration is 10 (cell) / m...

Embodiment 3

[0034] Raw squid viscera was heated at a temperature of about 80°C for 10 to 15 minutes to kill miscellaneous bacteria; After fully stirring, the enzyme acts at normal temperature for 5 to 7 days, then sterilizes at 80° C. for 10 to 15 minutes, and returns to normal temperature to manufacture the target feed additive. This method is preferably used when the freshness of raw cuttlefish viscera is not very good.

Abstract

The present invention provides one kind of fish feed additive and its production process. The fish feed additive has ink fish organ as main material and is suitable for raising sea water fishes, especially prawn. It can balance nutrients, provide prawn with feasible energy and amino acids, and provide proper amount of chlesterol to promote growth of prawn during desquamation. During the production, fresh ink fish organ as main material is fermented naturally or enzyme fermented via adding composite lactic acid bacteria, which is obtained through culture and propagation in composite fruit juice or molasses, as fermentation promoter. Higher protein contained in ink fish organ is decomposed, so as to produce fish feed additive containing rich amino acids and unsaturated fatty acid.

Description

technical field [0001] The invention relates to a feed additive for fish farming and a manufacturing method thereof. The feed additive for fish farming uses cuttlefish viscera as the main raw material and is applied to fish culture on the surface of sea water, especially when added to shrimp feed, not only can the nutrients be balanced , can also supply the high energy and amino acid needed for the growth of shrimp, and supply the right amount of cholesterol in the process of peeling the shrimp to promote the growth of the shrimp. Background technique [0002] In the past, squid viscera were mainly used as feed additives for shrimp and fish through the following processing techniques. [0003] That is, put the collected squid viscera in an iron kettle, heat it with steam to above 120°C, boil it for about 3 hours or more to evaporate the water, separate the fat part by concentrating and heating, extract it as squid liver oil, and the remaining paste The product is called squ...
