Temperature control of poultry breeding in spring

1. Spring climate characteristics:

Temperature changes: large temperature difference between morning and evening

wind changes

Spring breeding key

1) Temperature stabilization: overlooked points and difficulties in environmental control

Low temperature and sudden temperature drops are important causes of disease

2) Low temperature signal of chicken shed:

Intuitive signals: eggshell quality, feed consumption, water consumption, feces condition (shape, color)

Objective Signal: Duration of Peak Egg Production

Computing data: big data, cloud computing, blockchain, artificial data

(Peak drinking water: before and after eating, after laying eggs)

1. Temperature control of chicks in spring (raised in counter-season)

Note: Pay attention to the temperature of the chicken house. The temperature should be stable. The temperature difference in the first three days should be within 2°C. Large temperature differences will hinder feather development.

In the early stage of brooding, the temperature should not deviate from the recommended temperature in the feeding manual by 0.5°C, and in the later stage, the temperature should not deviate from ±1°C.

2. Young Chicken

Suitable temperature: 24~26℃, the fat deposition rate is best at this temperature (after 6 weeks of age)

After 8 weeks of age, the length of the ovaries and fallopian tubes develop best at 22°C.

3. Laying hens

Suitable temperature: 15~25℃, optimal temperature: 18~23℃. Chicken flocks perform best at 21°C.

The day and night temperature in the house is best controlled within 5℃, the horizontal point in the house is controlled within 2℃, and the temperature difference at the vertical point is controlled within 1℃.
