The height-adjustable of curved bend curved bar, both ends are fastened on front side of main body on vertical beam by screw rod.
Three, fecaluria collection part
It is about 0.6 meter high as shown in Figure 1, fecaluria collection part is located at cuboid bottom, it is thrown the net plate 3 and two mould plates 4 by two Composition, two plates of throwing the net respectively are about 1.0 meters, 1.2 meters wide, and two throw the net plate respectively and ground level at 30 ° of angles builds fixation, and angle is not Yi Tai great, otherwise it is too fast to tumble speed for excrement ball, and web plate grid is 30-40 mesh, and excrement, urine flow on this web plate point from metabolic cage bottom plate From urine is flowed down from web plate grid, and excrement is tumbled along inclined web plate in web plate two sides, and there are excrement slot 10 in two sides, and sheep dung rolls into Excrement slot manually collects excrement in excrement slot.Two mould plates are located at two and throw the net on the downside of plate, are respectively about 1 meter, 1.2 meters wide, two sides are away from web plate It 10 centimetres, is fixed with level at 60 ° of angles, and two mould plates tilt about 10-15 ° in the same direction, inclined bottom, which is placed, receives Collect basin, such urine flows to bottom web plate along metabolic cage bottom grid, then flows to mould plate by web plate, flows into again from mould plate It collects in basin, to complete the collection of excrement, urine.
Four, water system
The water pipe of all metabolic cages is connect in the different junctions of same water-main, in metabolic cage with mode in parallel Portion's about 40cm height connects a sheep tass, and sheep can drink water in bowl automatically.
Application method:
1, when doing metabolic test, in the rear side of metabolic cage, open door, take an inclined plate in the position of door, will test sheep catch up with into Metabolic cage.
2, it when feeding sheep, as required by feed weighing, is poured into from front end crib mouth by material.
3, when drinking water, sheep is allowed only to know spigot and method with the mode lured for the first time, sheep is just learned quickly.
4, excrement, urine are collected, and in the bottom of metabolic cage, clear up fecaluria on time daily, and excrement artificially collects in excrement slot, weighing, Drying, in case subsequent analysis.Urine is poured into assay flask, weighing in the chamber pot basin of lower part, freezing, analysis.
5, other correlation tests can carry out all in metabolic cage.
Finally, it should be noted that the foregoing is only a preferred embodiment of the present invention, it is not intended to restrict the invention, Although the present invention is described in detail referring to the foregoing embodiments, for those skilled in the art, still may be used To modify the technical solutions described in the foregoing embodiments or equivalent replacement of some of the technical features. All within the spirits and principles of the present invention, any modification, equivalent replacement, improvement and so on should be included in of the invention Within protection scope.
