Abstract

The utility model provides a special wooden pad for experimental rodents. Natural, nontoxic and tasteless wood is processed into cuboid particles of which the length, the width and the height respectively range from 1 mm to 10 mm, and then, the particles are dried and screened to form the utility model. The special wooden pad for experimental rodents can solve the problems of the non-standardization, the unclear origin and the chemical pollution of the existing pad for experimental animals; the standardization and the industrialization of the pad for the experimental animals are realized, and the quality of the bred experimental animals is guaranteed.

Description

The special-purpose wood substance grain bedding and padding of laboratory rodent

Technical field

The utility model relates to the bedding and padding that are used to raise laboratory rodent, more specifically, the utility model relates to the special-purpose wood substance grain bedding and padding of a kind of novel laboratory animal, and it is applicable to raises various laboratory rodents, as rat, mouse, suslik, cavy etc.

Background technology

Bedding and padding are one of essential conditions in the laboratory rodent captive breedings such as big mouse.

Bedding and padding commonly used at present are discarded wood shavings and sawdust, and they do not have the shape of rule, and the sawdust bedding and padding is small-sized.

Yet, directly utilize discarded wood shavings or sawdust to have following problem as bedding and padding:

Because discarded wood shavings light weight volume is big, belongs to " bulky cargo ", not further carries out deep processing, thereby all have certain problem on all links such as packing, transportation, storage.

Therefore, this area presses for the new standardized laboratory animal bedding and padding of exploitation, so that pack, transport, store.

Summary of the invention

The purpose of this utility model provides the special-purpose wooden bedding and padding of a kind of novel laboratory rodent.The special-purpose wooden bedding and padding of laboratory animal of the present utility model can solve the nonstandardized technique problem of present laboratory animal bedding and padding, realize the standardization and industrialization of laboratory animal bedding and padding, guarantee the laboratory animal quality of raising.

The technical scheme that the utility model provides is as follows:

A kind of wooden bedding and padding of laboratory rodent special use, described bedding and padding are cuboid or square, long 1-10mm, wide 1-10mm, high 1-10mm.

In another preference, described bedding and padding are the square bodily form.

In another preference, described bedding and padding are cuboid.

In another preference, the material of described bedding and padding is with the timber that is selected from down group: poplar, birch, maple or its mixture.

In another preference, described bedding and padding do not contain≤0.5 micron dust particle.

In another preference, described bedding and padding are through sterilization.

In another preference, the long 1.5-5mm of described bedding and padding, wide 1.5-5mm, high 1.5-5mm.

Description of drawings

Fig. 1 has shown the preparation process of animal bedding and padding of the present utility model.

Fig. 2 has shown the schematic diagram of animal bedding and padding in example of the utility model.

Embodiment

The inventor finds that granular wooden bedding and padding are particularly suitable for letting animals feed.Finished the utility model on this basis.

Can be used for timber of the present utility model is to making with the timber that is selected from down group: poplar, birch, maple or its mixture.

The special-purpose wooden bedding and padding of the novel laboratory rodent that the utility model relates to be with selected nonpoisonous and tasteless natural timber through machining, drying, sieve and technology such as pack and make.

Referring to Fig. 1.Particularly, the manufacture craft of the special-purpose wood substance grain bedding and padding of laboratory rodent of the present utility model comprises:

(a) select timber such as poplar, birch and maple nonpoisonous and tasteless, abundant raw material, remove bark and impurity;

(b) be processed into wood substance grain of the same size with machine and wood cutting;

(c) by drying installation the water content of wood substance grain is dropped in 15%;

(d) screen out dust, insect and mistake granule;

(f) with packaging bag or packing case airtight package, insect protected, protection against the tide and go mouldy;

(d) sampling inspection is stored in the warehouse or transports the client to.

The wooden bedding and padding of the laboratory rodent special use that makes are cuboid or square, and length a is that 1-10mm, width b are that 1-10mm, height c are 1-10mm.(Fig. 2)

Advantage of the present utility model is:

(1) industrialization and the standardization of realization laboratory rodent bedding and padding.

(2) easily packing and transportation of graininess bedding and padding.
