Abstract
The invention discloses a procambarus clarkii compound feed and belongs to the field of aquaculture and feed science. In the compound feed, powdery feeds, such as corn powder, soybean powder, wheat middling, starch and the like are subjected to pre-processing to prepare a puffed feed packaged mixture, wherein the soybean powder and an energy feed powder are embedded inside a hollow part of the puffed corn powder. The feed are packaged through addition of edible oil, can be directly put on a feed bench for enabling the procambarus clarkii to intake and also can be thrown into water. The feed, when being thrown into water, can sink stably and gradually for enabling the procambarus clarkii to intake.
Description
Technical field
The present invention relates to aquaculture and feed field, relate in particular to a kind of lead and cadnium mixed feed.
Background technology
Lead and cadnium is the economic freshwater shrimp species of China from external introduction, also claims cray.Lead and cadnium because of nutritious, meat flavour is delicious, extensively popular to people, it belongs to Omnivore, fast growth, and fertility is strong, in recent years becomes the economic breed variety that China is important.
Existing lead and cadnium breeding mostly is extensive cultivation, even if bad environments cray of feeding still can have objective growing way, but the thing followed is food safety and sanitation problem.And by cray in irrigation canals and ditches, pond culture, often throw spread muck to increase water body fertility, add the possibility of infected by microbes, and consumer can be affected buy.
In addition, even if produced on the market and the mixed feed of the multiple cray that circulates at present, but this mixed feed all carries out improvement obtain based on traditional fowl crab mixed feed, carp compound feed, do not meet the requirement of cray to energy and special dietary, its physical aspect does not meet the growing environment of lobster yet.
Summary of the invention
Goal of the invention: the object of this invention is to provide and a kind ofly take into account lobster energy and proteinaceous nutrient demand and a kind of lead and cadnium mixed feed of coupling facilities environment; Another object of the present invention is to provide the preparation method of expanded component in this feed.
Technical scheme: in order to realize foregoing invention object, a kind of lead and cadnium mixed feed of the present invention, comprises following component: energy feed puff 75 ~ 85% by mass percentage, fish meal 8 ~ 12%, cottonseed cake 0 ~ 10%, bone meal 0 ~ 10%, vitamin premix 1.5 ~ 2.5%; Wherein, described energy feed puff is obtained by some energy feed powder raw materials is expanded through independence, pulverizing, mixing, homogenizing step;
Described some energy feed powder raw materials, comprising: soy meal 38 ~ 50%, corn flour 18 ~ 22%, secondary powder 30 ~ 40%, starch 0 ~ 5% relative to puff raw material gross mass percentages by it.Although it should be noted that soy meal is protein feeds here, energy feed powder described in the present invention also comprises soy meal, in view of being all mixed under identical processing technology, is therefore referred to as energy feed powder.Of the present invention time powder addition is more, ensure enough absorptions of energy, but the shortage of secondary powder is as other important nutrients such as riboflavin, is made up by interpolation soy meal, corn flour.Add certain starch can contribute to improving gelatinization effect.
As further optimization of the present invention, described mixed feed is by mass percentage by forming as follows:
Energy feed puff 77.5%,
Fish meal 10%,
Cottonseed cake 5%,
Bone meal 5%,
Vitamin premix 2.5.
As preferred version of the present invention, described energy feed powder raw material, relative to puff raw material gross mass percentages, is made up of following component:
Soy meal 42%,
Corn flour 19%,
Secondary powder 34%,
Starch 5%.
Mixed feed of the present invention also relates to specific puffing process technique, and a kind of preparation method of energy feed puff, specifically comprises the steps:
(1) by raw material gross mass percentage, by expanded to corn flour 18 ~ 22%, secondary powder 30 ~ 40%, starch 0 ~ 5%, pulverize;
(2) by raw material gross mass percentage, by homogeneous under soy meal 38 ~ 50% heated condition;
(3), under adding the spraying of total raw material 1% vegetable oil, the soy meal that step (2) obtains is sprayed on puffing material that step (1) obtains.
Preferred as technique scheme, by raw material gross mass percentage, each raw material components is made up of soy meal 42%, corn flour 19%, secondary powder 34%, starch 5%.
Wherein, described bulking process moisture initial adjustment is between 14 ~ 16%, and expanded rear moisture maintains 2% ~ 4%.
Beneficial effect: mash feed has been carried out preliminary working and made expanded pellet diet packing mixture by mixed feed of the present invention, through expanded corn flour hollow bulb embedding soy meal and energy feed powder, and encapsulate by adding vegetable oil, directly can throw in and search for food for cray on feed table, also water entering surface can be shed, sink gradually Absorbable organic halogens, search for food for lobster.
