A kind of health black carp feed
Technical field
The present invention relates to a kind of aquatic animal feed, be specifically related to a kind of health black carp feed, be particularly suitable for as the black carp feed for fingerling.
Background technology
Black carp claims again " spiral shell green grass or young crops " that build is cylindrical, and afterbody is flat-sided, the belly circle; The body back of the body and side first half lividity, the belly milky is one of four large Chinese carps of China.Black carp live in more water body in, lower floor, dislike water surface activity, wild black carp seedling stage is food with the zooplankter, adult fish is main food with shell mollusks such as spiral shell, yellow a species of small clam living in fresh waters then.
It has been generally acknowledged that fish are limited in one's ability to utilizing of sugar (carbohydrate), predacious fish is lower to utilization energy force rate herbivorous fishes, the ominivore-fish of sugar.Therefore, when preparation black carp practicality feed, only pay attention to Protein content and amino acid whose proportioning, and do not consider the influence of the content of sugar.Even add some times powder in some feed formula, also be to consider from the angle that reduces feed cost, enhancing feed water stability, do not see the report that adds glucose.
On the other hand, need in feed, add materials such as immunopotentiator, with the immunity of raising black carp, and, also need in feed, add antioxidant, this class antioxidant easily produces toxic and side effect.
Summary of the invention
The object of the invention provides a kind of new health black carp feed, can improve the immunity of fish, and the harmful effect of avoiding the antioxidant that adds etc. to produce.
For achieving the above object, the technical solution used in the present invention is: a kind of health black carp feed comprises animal protein source, vegetable protein source, fat, vitamin, mineral matter and sugared source, the content of sugar is between 15% to 25% in the feed, and wherein the content of glucose is not less than 2%.
In the technique scheme, the higher material of animal protein content that is used as fish feed formula usually, for example fish meal, meat meal tankage etc. can be adopted in described animal protein source; Described vegetable protein source can be selected dregs of beans, cotton dregs, the dish dregs of rice etc. for use; Vitamin and mineral matter can directly adopt commercially available fish feed additive, perhaps add calcium monohydrogen phosphate, salt etc. outside some additive as required again; Starch, inferior powder, flour, wheat bran etc. can be used in described sugared source, but need add glucose separately.
Further technical scheme, described black carp feed is made up of following component, counts with the air dry matter percentage by weight:
Fish meal 2-15%
Digested tankage 0-15%
Dusty yeast 0-15%
Fermented blood meal 0-10%
Dregs of beans 20-40%
Cotton dregs 10-20%
Dish dregs of rice 10-40%
Shelled peanut dregs of rice 0-15%
Sunflower seed dregs 0-15%
Inferior powder or flour 7-15%
Glucose 2-8%
Rice bran 0-10%
Wheat bran 0-10%
Fish oil 0-1%
Vegetable oil 0-5%
Additive 1-6%
Described additive is the mixture that contains various vitamins and mineral matter.
Because the technique scheme utilization, the present invention compared with prior art has following advantage:
1. because the present invention has added the sugar of suitable quantity in the black carp feed prescription, through studies show that of inventor, add carbohydrate and not only can improve protein efficiency ratio, PER, save protein, also have certain immunologic enhancement, particularly the immunologic enhancement with glucose is the most remarkable;
2. behind the adding glucose,, do not need to add in addition antioxidant, avoided the issuable toxic and side effect of use antioxidant because glucose has antioxidation;
3. sugar is the most cheap feed source, and the present invention has avoided people and thought that fish utilize understanding mistaken ideas limited in one's ability to sugar, adds sugar in carnivorous black carp feed, reduced feed cost to a certain extent, simultaneously, polysaccharide such as inferior powder have adhesive effect, have improved the water stability of feed.

According to the water temperature situation, can do suitably to adjust to above-mentioned prescription, its nutrition should meet the requirements for, protein about 35%, amino acid is near balance, fat about 4%, sugared 15-25% wherein is glucose about 2-8%.Usually, suitable sugared content was higher when water temperature was high, the suitable corresponding reduction of sugared content when water temperature is low.
Feed and the commercial goods material of embodiment one, embodiment two, embodiment three and embodiment four are compared experiment, show, its oxidation resistance of test group of use feed of the present invention is significantly higher than the control group of the commodity material of ingesting.The power and the health degree of the oxidation resistance of body defense system exist confidential relation, and oxidation resistance improves the explanation body, and to remove in the body harmful free radical ability stronger, and oxidation resistance usually causes the generation of various diseases when reducing.Therefore, contain a certain amount of carbohydrate in the feed to the black carp healthy and beneficial, but diet carbohydrate when too high oxidation resistance can then descend, therefore, the diet carbohydrate level should be within described scope.Simultaneously, find in experiment that the erythrocyte fragility of black carp significantly descends along with the raising of diet carbohydrate content, shows that the certain sugared content of maintenance can also play the effect that prevents and treats hemorrhage in the feed.
