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. A device for collecting data used to establish a comfort evaluation model of chicken living environment

[0039] Such as figure 1 with figure 2 Shown is a multi-unit device composed of 2 devices. Each device includes a breeding cage composed of a cage bottom 12, a cage cover 3 and a cage wall, and the breeding cage is set 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 line 4 is connected with a metering water tank 1 for supplying water to the drinking line 4. A plurality of evenly distributed nipple drinkers 13 are provided on the drinking line 4 to facilitate the drinking of the test chickens. A food trough 6 is provided on the cage wall of the breeding cage for the feeding of test chickens, and the food trough 6 is arranged along the length direction of the breeding cage and is opposite to the drinking line 4, namely, the foo...

Embodiment 2

[0048] Example 2. Using the device in Example 1 to collect data for establishing a broiler lighting environment evaluation model

[0049] We selected 300 29-day-old Avian broilers with similar body weights and were randomly divided into 5 groups with 6 replicates in each group and 10 chickens in each replicate. There were 60 chickens in each group, which were raised in 15 groups of Example 1. In the breeding cage. Place each group in a climate chamber with different light periods (see below), and use tungsten filament lamps to illuminate the light with a light intensity of 5Lx. The temperature of each climate chamber is maintained at 20-22 degrees Celsius. Add a certain amount of chicken feed and chicken drinking water to the trough and the metering water tank respectively, and the chickens can eat and drink freely. Turn on the video capture device.

[0050] The photoperiods of the 5 test groups are:

[0051] Group A: 16 hours of light, then 8 hours of darkness;

[0052] Group B: ...

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 breeding environment directly affects the behavior, health, production performance and economic benefits of broilers. The establishment of a broiler environmental comfort evaluation model can be used to guide broiler breeding and is of great significance. Changes in production performance and behavior sensitively and reliably reflect the environmental comfort of broilers. Production performance includes body weight, feed intake, water consumption, and feed conversion rate; behavior indicators include the frequency or time ratio of lying down, eating, drinking, standing, walking, and grooming. [0003] The data required for modeling should be obtained under non-stres...
