Manure self-detaching metabolism cage

The utility model relates to a manure self-detaching metabolism cage, which comprises a cage body, a fecal leakage plate is arranged at the bottom part of the cage body, a urine collecting disk tilting down is correspondingly arranged below the fecal leakage plate, a urine outlet is formed at the tail end of the urine collecting plate tilting down, and a filter screen groove is correspondingly arranged above the urine collecting plate. When the manure self-detaching metabolism cage of the utility model is used, animals for research are reared in the metabolism cage, metabolin, excrement and urine of the animals can fall on the filter screen groove directly from the fecal leakage plate at the bottom part of the cage body, excrement can roll down along the inclined filter screen groove and fall into an excrement collecting groove finally, and urine can fall into the urine collecting disk by passing through the filter screen groove and then flows into a urine collecting container after flowing downwards into a urine collecting ditch. Therefore, excrement of the animals can be easily collected and sampled after classification, any influences can not be caused on the animals, and the utility model is suitable for sheep with different sizes and sexes, and the labor intensity is greatly reduced.
