Mixed powder, it is spare；
Sequentially added in step 3, the second mixed powder obtained in step 2 50 parts by weight fishes and shrimps protein hydrolyzate and
It is dry after the Chinese herbal medicine fluid of 10 parts by weight, third mixed powder is obtained, it is spare；
The vegetable oil of 30 parts by weight is added in step 4, the third mixed powder obtained in step 1, after stirring evenly, that is, makes
It obtains the cray and cultivates special feed.
<Test example>
By the cray of 7000 same periods, every 1000 are divided into one group, are divided into 7 groups of experimental groups, 7 groups of experimental groups are same
In the environment of cultivate, in addition to cray feed is different outer, other conditions all same, 7 groups of daily equivalent of experimental group is fed
The common commercially available cray of the cray cultivation special feed and outsourcing that are obtained in inventive embodiments 1-3 and comparative example 1-3
Feed, 7 groups of crays, culture efficiency is by the following table 1：
1 cray of table cultivates data
| Group | Using feed | Cultivate duration, day | The dead quantity, only | Single average weight, gram |
| 1 | Embodiment 1 | 120 | 28 | 45.6 |
| 2 | Embodiment 2 | 120 | 35 | 46.2 |
| 3 | Embodiment 3 | 120 | 37 | 44.8 |
| 4 | Comparative example 1 | 120 | 68 | 46.1 |
| 5 | Comparative example 2 | 120 | 41 | 41.4 |
| 6 | Comparative example 3 | 120 | 29 | 43.5 |
| 7 | Outsourcing | 120 | 98 | 39.2 |
As shown in Table 1, cray of the invention cultivates special feed for common commercially available cray feed, by
The difference of group 1-6 and group 7 can significantly improve the weight of single cray using the cray of its cultivation, while can
The death rate of cray can also significantly be reduced.
Although the embodiments of the present invention have been disclosed as above, but its is not only in the description and the implementation listed
With it can be fully applied to various fields suitable for the present invention, for those skilled in the art, can be easily
Realize other modification, therefore without departing from the general concept defined in the claims and the equivalent scope, the present invention is simultaneously unlimited
In specific details and embodiment shown and described herein.
