Description
Technical field
The present invention relates to shrimp feed field, in particular it relates to a kind of instead of shrimp feed of fish meal and preparation method thereof and should
With.
Background technology
Although China is priority to forests, but water resource very abundant, therefore is especially suitable for developing culture fishery, and fishes and shrimps are made
For food, its nutritive value is high, and nutritional ingredient is comprehensive, has good protein, mineral matter and main B family vitamin, preferably absorbs,
Its meat it is delicate and but also with a variety of necessary amino acid, fish body fat is undersaturated, is without fear of an attack from the rear after eating, and expert thinks only fish
Shrimp contains the required DHA of human brain development（Aliphatic acid）, so a large amount of eat can improve IQ, therefore Devoting Major Efforts To Developing fishes and shrimps are raised
Material is to improve the meat of culturing fish and shrimp, nutritive value and the speed of growth, and right and wrong are often with there is production practices meaning.
It with one or more fish is raw material that fish meal, which is, through deoiling, dehydration, and the high protein feed raw material after crushing and processing,
With good nutritional characteristic.Aquaculture and feed industry are fast-developing at present so that and supply falls short of demand for fish meal, which results in
Fish meal shortage and high price.
High-quality high protein novel fodder resource that is cheap, easily obtaining how to be found and opened up to substitute fish meal, with reality
Now reducing aquaculture cost turns into instantly most urgent task.
The content of the invention
It is an object of the invention to overcome the deficiencies of the prior art and provide a kind of shrimp feed instead of fish meal, the present invention carries

Wherein, the shrimp that comparative example 1 is raised is used as S1 groups, the prawn that embodiment 1 is raised as S2 groups, the raising of embodiment 2
Prawn is as S3 groups.
1 different shrimp feeds of test example are to the growth performance of Environment of Litopenaeus vannamei Low and the influence of liver body function
（1）Body weight
Fig. 1 is influence of the shrimp feed to Environment of Litopenaeus vannamei Low body weight, and as shown in Figure 1, body weight maximum occurs to raise S3 during 42d
Group substitutes 50%, numerical value 13.75375g, and S3 groups when minimum value is raises 6d substitute 50%, numerical value 5.7g, in 42d
When, S3 and S1, S2 significant difference（P<0.05>）S1 and S2 differences are not notable（P>0.05）, and the numerical value of S3 groups is all significantly greater than
S1, S2 group, S1 before 42d, S2, S3 do not show significant difference, illustrate that brewer's yeast substitutes fish meal and do not influenceed not only pair
The growth of shrimp body weight, moreover it is possible to reduce feed cost and S3 effects are best.
（2）Body is grown
Fig. 2 is the influence that shrimp feed is grown to Environment of Litopenaeus vannamei Low body, and as shown in Figure 2, body length maximum occurs to raise S3 during 42d
Group substitutes 50%, and numerical value is S3 groups i.e. 50% when 13.2cm. minimum values are raising 6d, numerical value 7.25, is tested entirely
S1 in journey, S2, do not occur significant difference between S3, illustrate that brewer's yeast substitutes fish meal and do not influence the increasing of prawn body length not only
It is long, moreover it is possible to reduce feed cost and S3 effects are best.
（3）Liver body index
Fig. 3 is influence of the shrimp feed to Environment of Litopenaeus vannamei Low liver index, as shown in figure 3, liver body index maximum appears in raising 28d
When S3 groups 50%, numerical value is S2 groups i.e. 25% when 0.047. minimum values appear in 35d, and numerical value is entirely being tested for 0.03.
During S1, do not occur significant difference between S2, S3（Fig. 3）, and liver body index is up to S3 groups.
（4）Liver body function-to glutamic-oxalacetic transaminease（Ast/Got）Influence
Fig. 4 is shrimp feed to Environment of Litopenaeus vannamei Low glutamic-pyruvic transaminase（GPT&ALT）Influence, as shown in figure 4, glutamic-oxalacetic transaminease is maximum
S2 groups when value appears in raising 14d substitute 25%, and numerical value 22.97U/mgprot, minimum value is appeared in when raising 20d
S2 groups substitute 25%, numerical value 4.69u/mgprot, all occur when raising 6d, between S1 and S2, S1 and S3, S3 and S2 aobvious
Write difference（p<0.05）And S3 group glutamic-oxalacetic transamineases content is all higher than S1, S2.When raising 14d, with S2, S3 significance difference occurs for S1
It is different（p<0.05）, significant difference (p does not occur for S2 and S3>0.05) and S3 group glutamic-oxalacetic transamineases content is all higher than S1, S2, is raising
During 20d, with S1, S2 significant difference occurs for S3（p<0.05）, significant difference (p does not occur for S1 and S2>0.05) and S3 groups millet straw turns
Ammonia enzyme content is all higher than S1, S2, and significant difference all no longer occurs between S1, S2, S3 after 28d is raised.
（5）Liver body function-to glutamic-pyruvic transaminase（GPT&ALT）Influence
Fig. 5 is different shrimp feeds to Environment of Litopenaeus vannamei Low glutamic-oxalacetic transaminease（Ast/Got）Influence, as shown in figure 5, glutamic-pyruvic transaminase
S2 groups when maximum appears in raising 14d substitute 25%, and numerical value is 22.97 u/mgprot, when minimum value appears in 20d
S2 groups i.e. substitute 25%, numerical value be 8.9 u/mgprot, when raise 6d, S1 and S2, S3 generation significant difference（p<0.05）,
Significant difference (p does not occur for S2 and S3>0.05) and S3 group glutamic-pyruvic transaminase content is all higher than S1, S2, when raising 14d, S1 with
Significant difference all occurs between S2, S1 and S3, S3 and S2（p<0.05）And S2 group glutamic-pyruvic transaminase content is all higher than S1, S3.
When raising 20d, with S1, S2 significant difference occurs for S3（p<0.05）, significant difference (p does not occur for S1 and S2>And S3 group paddy 0.05)
Pyruvic transaminase content is all higher than S1, S2, and significant difference all no longer occurs between S1, S2, S3 after 28d is raised.
