Description

Aquatic animal metabolism experiment excrement and urine collection device

Technical Field

The utility model relates to the technical field of excrement collection devices, in particular to an aquatic animal metabolism experiment excrement collection device.

Background

The nutrient substances in the feed which are digested and absorbed by animals are called digestible nutrient substances, and the percentage of the digestible nutrient substances in the feed accounting for the ingested nutrient substances becomes digestibility. In the aquaculture industry, the feed digestibility is one of methods for evaluating the nutritional value of feed, measuring the utilization efficiency of compound feed and checking the rationality of feed formula setting, and has important reference value for research on the nutrient demand of aquatic animals and evaluation of the influence of feed on water environment.

At present, each large feed enterprise and scientific research institutes usually detect the digestibility through the total manure collection method, and unlike livestock and poultry, the special nature of aquatic animal living environment makes manure collection work more difficult, and nutrient components and inorganic substances in manure are easy to dissolve in water in the collection process, and the digestibility measurement result is inaccurate. The method for collecting the excrement of aquatic animals directly affects the measurement result of the digestibility, and the common excrement collecting method can be divided into two main types, namely an in-vivo method and an in-vitro method. Although in vivo methods represented by extrusion, dissection and anus fecal suction can effectively avoid the problem of losing nutritional ingredients in water, repeated capturing of experimental fish can cause stress reaction of fish, and digestion conditions under natural conditions cannot be reflected; and the obtained feces do not complete the natural digestive metabolic process, and are mixed with digestive juice secreted in the body, mucus and exfoliated epithelial cells, resulting in a lower digestibility than the true value. In vitro methods, particularly siphoning methods, although the most time and effort consuming, can collect the excrement discharged by experimental fish in time from the water body, reduce the dissolution loss of nutrients in the water body, make the measured digestibility value more approximate to the true value, and are widely used in aquatic animal culture experiments at present.

How to solve the technical problems is the subject of the present utility model.
