Test method for rodent predation

Abstract

The invention discloses a test method for a rodent predation behavior. The test method comprises the following steps: fasting an animal to be tested for 12 hours but not depriving water; at 5 in the afternoon, placing the animal to be tested in an open field to adapt for 2 hours; at 7 in the afternoon, putting 250g of food which is equivalent to the weight of the animal in the open field; and then through three different predation behaviors namely competitive predation behavior, non-competitive predation behavior and non-obstacle predation behavior, observing the predation condition of the animal, and analyzing three different predation behaviors and predation amounts, wherein the whole predation course is shot by a digital video. The method can be used for determining the advanced cognitive function of the animal in no need of manual intervention, and the judgment is standard and explicit; the animal behavior is influenced by environmental factors and manual training factors, thus the method has operability and practicability. By using the method, the drain regions, playing a role in the predation behavior, of the animal can also be studied, and the influence of a medicament on the predation behavior is further studied.

Description

technical field [0001] The invention belongs to the field of experimental zoology, and in particular relates to an experimental method for the predatory behavior of rodents. Background technique [0002] Predation is a ubiquitous phenomenon in nature, and the predation of food can best reflect the advanced cognitive functions of animals such as competitive state, long-term planning and decision-making. In the past, the method used to observe the predatory behavior of animals was to make the animal find out food from a hole or take out food from a cylinder. The observation was usually carried out during the day and the time was very short. These observation methods could not objectively reflect the predatory behavior of animals. It cannot simulate the predatory behavior of animals in the natural state very well, and has certain limitations such as: (1) the test time does not conform to the predatory habits of rodents (usually at night); (2) the observation The time is relati...

In the past, the method used to observe the predatory behavior of animals was to make the animal find out food from a hole or take out food from a cylinder. The observation was usually carried out during the day and the time was very short. These observation methods could not objectively reflect the predatory behavior of animals. It cannot simulate the predatory behavior of animals in the natural state very well, and has certain limitations such as: (1) the test time does not conform to the predatory habits of rodents (usually at night); (2) the observation The time is shorter, usually less than 60 minutes; (3) The animals have been trained before the test, and they cannot truly respond to the animal's predatory instinct
