Description
Technical field
The present invention relates to a kind of laboratory animal experimental rig, be specifically related to a kind of for zooperal laboratory animal pellet home-made contrivance.
Background technology
Current is unusual time of new technology revolution, bioengineering, microelectric technique, new material and new forms of energy by leaps and bounds develop, the twenty eleventh century mankind will step into the New Times of life science, zoopery has become the basic skills of medical experiment research, and zoopery science has been subject to common concern and the attention of countries in the world.As studied various disease and old and feeble mechanism; monitoring public hazards, pollution; the environment of protection human survival; produce how better agricultural and animal products; the research of medicine, biological products, agricultural chemicals, food, additive, chemical products, cosmetics, space flight, radioactivity and war products test, to produce; in import-export commodity inspection, be indispensable to the research of animal used as test.
The experimentally difference of object, needs to implement different manual interventions to animal used as test, as added at feed the important content that enzyme preparation has become 21st century feed technology revolution.Rationally and effectively in animal feed, use various enzyme preparation, the deficiency of the digested enzyme of animal body can not only be made up; Participate in destroying plant cell wall construction, eliminate the process of various ANFs in vegetality feedstuff; Reduce animal intestinal chyme viscosity, improve the effect etc. of metabolism intensity and raising immunity of organisms in animal body.
Conventional feed, in pelletization, could need be shaped after the extruding of modified, pressure roller and pressing mold.In modified process, the general steam of 0.2-0.4MPa that adopts processes, and steam temperature can reach 120-142 DEG C, and under the effect of steam, feed temperature rises to 80 ~ 93 DEG C, and moisture reaches 16% ~ 18%.When pelleting temperature is lower than 80 DEG C, the loss of activity of cellulase, amylase and pentosanase is little, but when temperature reaches 90 DEG C, cellulase, Mycophyta amylase and pentosanase loss of activity are very large, loss late is more than 90%, and bacterium kind of starch enzyme loses about 20%.Pelleting temperature is more than 80 DEG C, and phytase activity loss late reaches 87.5%.Frictional force increases, phytase loss late is improved, when nib aperture is the pressing mold granulation of 2mm, phytase loss late is the pressing mold of 4mm higher than aperture. Liu Meiying etc. equally also point out in the research of Effects of Feed Processing on Nutrition, existing different feed processing technology all has impact, the particularly material of some condition non-refractories in various degree to protein, fat, starch, cellulose, vitamin etc.
In the test that experimental period is long, be the most popular method that animal is intervened by GI means of intervention.The simplest addition manner is added in the feed of mouse medicine, certain nutritional labeling or certain material.Existing conventional adding method has: test substance is spread upon the surface of mouse feed by (1), this Measures compare is simple, shortcoming is the homogeneity not ensureing to smear, and the standardization of animal used as test feed is one of key factor ensureing the Quality Control of experimental study quality; (2) Experimental Animal Center of existing production feed also has feed for processing service, and this method is convenient and swift, but due to mechanically operated reason, processing each sample at least needs 25kg.In experimentation, on the one hand, the forage volume of a certain simple sample concentration may be have more than is needed so much, and this just causes the expense that allows, and invisiblely improves experimental cost.On the other hand, high temperature, high pressure, heavy metal ion etc. in mechanical feed manufacturing process formed feed process (mainly granulate and expanded) can cause some active material inactivations.In addition, the price of pelleter in the market more than several thousand yuan to ten ten thousand yuan not etc., be also a no small spending for buying a machine Scientific Research in University Laboratory.Therefore, in order to reduce expenses, some laboratory adopts self-control feed.The method of common self-control pellet has: (1) rolls.After being stirred by mixed feed, put into willow basket or washbasin, the same with rolling the way on Lantern Festival.(2) shake.Mixed fodder is added suitable quantity of water to stir, can be agglomerating to hold.(3) roll.After mixed fodder is tempered, with rolling pin processing, laminate, then be cut into noodles shape, can feed after drying.But, there is following problem in these manual homemade feeds: agglomerate size shape heterogeneity, quality heterogeneity, and that is difference of hardness, palatability are bad, in addition, because the drying causing having in dry run not of uniform size is excessive, the not yet dry-out phenomenon had.Research shows inclined to poor to this feed of mouse.In sum, between above various reasons, a kind of economy is researched and developed in laboratory, applicable pellet preparation facilities is very necessary.
