Problems solved by technology

[0003] The data required for modeling should be obtained under non-stress or as low as possible stress conditions, but the existing collection methods and corresponding test devices mainly have the following problems: when weighing, capture The method of weighing, this method is not only cumbersome, but also causes great stress to the test chicken; it is impossible to count the amount of drinking water in the unit of test treatment or repetition; in addition, the behavioral changes of broiler chickens cannot be observed with stacked cages, and The stocking density per unit space is relatively high, and there is a serious sense of depression, which leads to psychological stress in broilers, etc.
The stress caused by the collection method and the corresponding test device to the broiler interferes with the authenticity of the data to varying degrees; the behavioral changes cannot be observed, and the drinking water cannot be counted, resulting in missing data information

Embodiment 1

[0038] Embodiment 1, collection is used to establish the device of the data of chicken living environment comfort evaluation model

[0039] Such as figure 1 with figure 2 Shown is a multi-unit device consisting of 2 devices. Each device comprises a culture cage made of cage bottom 12, cage cover 3 and cage wall, and this culture cage is located on a support. A drinking water line 4 is fixed on the support, and the drinking water line 4 is arranged along the length direction of the breeding cage. One end of the drinking water line 4 communicates with a metering water tank 1 for supplying water to the drinking water line 4 . On this drinking water line 4, be provided with a plurality of evenly distributed teat drinkers 13, facilitate the drinking water of test chicken. On the cage wall of this breeding cage, be provided with food trough 6, be used for the food intake of test chicken, and this food trough 6 is arranged along the lengthwise direction of breeding cage, and is ...

Embodiment 2

[0048] Embodiment 2, utilize the device collection in embodiment 1 to be used for establishing the data of broiler light environment evaluation model

[0049] Select 300 29-day-old Avian broilers with close to the same body weight and health, and randomly divide them into 5 groups, with 6 repetitions in each group, 10 chickens in each repetition, a total of 60 chickens in each group, and raise them respectively in 15 chickens of Example 1. in breeding cages. Each group was placed in a climate chamber with different photoperiods (see below), irradiated with tungsten lamps, and the light intensity was 5Lx. The temperature of each climate chamber is maintained at 20-22 degrees Celsius. Add quantitative chicken feed and chicken drinking water to the trough and metering water tank respectively, and the chickens eat and drink freely. Turn on the video capture device.

[0050] The photoperiods of the five test groups were as follows:

[0051] Group A: light for 16 hours, then dar...

Abstract

The invention discloses a method and a special device for collecting data used for establishing a broiler living environment comfort evaluation model. The special device comprises breeding cages; the wall of each breeding cage is provided with a water-dispensing line and a feed trough; a drawer dropping tray is arranged below the bottom of each breeding cage; every water-dispensing line is communicated with a metering water tank; the bottom and wall of each breeding cage are movably connected in a separable manner; and a fork scale is arranged below the bottom of each breeding cage. The method includes: placing a test broiler into one breeding cage; turning on a video collector; controlling the living environment for the test broiler according to conditions of a predetermined living environment evaluation model to be established, and collecting the data, used for establishing the broiler living environment comfort evaluation model, according to the predetermined time. The method is applicable to the evaluation of boiler environment comfort and available for accurately collecting basic data such as broiler productivity and behavioral change under no capture stress, depression stress and high density stress for the evaluation on broiler environment comfort.

Description

technical field [0001] The invention relates to a method and a special device for collecting data for establishing an animal model, in particular to a method and a special device for collecting data for establishing a broiler living environment comfort evaluation model. Background technique [0002] The comfort of the feeding environment directly affects the behavior, health, production performance and economic benefits of broilers. Establishing an environmental comfort evaluation model for broilers can be used to guide broiler breeding, which is of great significance. Changes in performance and behavior are sensitive and reliable responses to broiler environmental comfort. Production performance includes body weight, feed intake, drinking water, and feed conversion rate; behavioral indicators include the frequency or time ratio of lying down, feeding, drinking, standing, walking, and grooming. [0003] The data required for modeling should be obtained under non-stress or ...
