Description
Technical field
The utility model relates to a kind of laboratory animal experiment device, is specifically related to a kind of laboratory animal pellet feed home-made contrivance for experimentation on animals.
Background technology
It it is currently the eventuality of new technology revolution, biotechnology, microelectronics, novel material and new forms of energy develop with advancing by leaps and bounds, the twenty eleventh century mankind will step into the New Times of life science, experimentation on animals has become the basic skills of medical experiment research, and experimentation on animals 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; medicine, biological products, agricultural chemicals, food, additive, Chemicals, makeup, space flight, radioactivity and war products research test, produce in; in import-export commodity inspection, it is indispensable to the research of laboratory animal.
The experimentally difference of object, it is necessary to laboratory animal is implemented different manual interventions, as added, at feed, the important content that zymin has become two eleventh century feed technology revolutions. Rationally and effectively in animal-feed, use various zymin, it is possible not only to the deficiency making up the digested enzyme of animal body; Participate in destroying vegetable cell wall construction, eliminate the process of various antinutritional factor in vegetality feedstuff; Reduce animal intestinal chyme viscosity, it is to increase the effect etc. of substance metabolism intensity and raising immunity of organisms in animal body.
Conventional feed, in granulation process, could need to be shaped after the extruding of modified, pressure roller and pressing mold. In modified process, the steam of general employing 0.2-0.4MPa processes, and vapour 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 big, rate of loss is more than 90%, and bacterium kind of starch enzyme loses about 20%. Pelleting temperature is more than 80 DEG C, and phytase activity rate of loss reaches 87.5%. Frictional force increases, phytase rate of loss is improved, when nib aperture is the pressing mold granulation of 2mm, phytase rate of loss 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, protein, fat, starch, Mierocrystalline cellulose, VITAMIN etc. are all had impact in various degree, the particularly material of some condition non-refractories by existing different feed processing technology.
In the test of length experimental period, it is the most popular method that animal is intervened by the means of intervention of gi tract. The simplest addition manner medicine, certain nutritive ingredient or certain material is added in the feed of mouse. Existing conventional addition means has: test substance is spread upon the surface of mouse feed by (1), this kind of Measures compare is simple, shortcoming is the homogeneity not ensureing to smear, and the stdn of laboratory animal feed is one of key factor ensureing experiment research quality Quality Control; (2) Experimental Animal Center of existing production feed also has feed for processing service, and this kind of method is convenient and swift, but due to power operation, processing each sample at least needs 25kg. In experimentation, on the one hand, the feed amount of a certain simple sample concentration may be have more than is needed so much, and this just causes the expense that allows, and invisible improves experimental cost. On the other hand, the high temperature in the machinery feed manufacturing process formed feed course of processing (mainly granulating with expanded), high pressure, heavy metal ion etc. can cause some active substance inactivations. In addition, the price of the pelleter in existing market at several thousand yuan to more than ten ten thousand yuan not etc., is 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 granulated feed has: (1) rolls. Mixed feed is stirred after evenly, put into willow basket or washbasin, the same with rolling the way on Lantern Festival. (2) shake. Mixed fodder adds suitable quantity of water stir, can be agglomerating to hold. (3) roll. Mixed fodder is added water after being in harmonious proportion, 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 inequality one, quality inequality one, and that is difference of hardness, palatability are not good, in addition, cause the drying having in drying process excessive due to not of uniform size, the not yet dry-out phenomenon having. Research shows inclined to poor to this kind of feed of mouse. In sum, between above various reasons, it is very necessary that a kind of economy, applicable granulated feed preparation facilities are researched and developed in laboratory.
