Embodiment 1

[0025] The test chicken farm selects a certain large-scale farm in Anyang City, and selects 40,000 Hailan brown layer hens that are healthy at the age of 35 weeks and have a similar weight and are randomly divided into 2 groups. I is a test group and II is a control group. For cooling control, the control group adopts the common cooling method in the prior art. The pre-test period is 1 week, and the main test period is 4 weeks.

[0026] The length, width and height of the chicken house are 120m, 12.2m and 2.7m. The facilities of the chicken house are the same, three layers of ladder cages, 16 hours of regular light per day, light intensity of 15-25lx, artificial feeding, free access to food and water. After a one-week pre-test period, it was confirmed that there were no significant differences in the average egg production rate, average egg breaking rate, average egg weight, and feed intake among the groups, and entered the main test period.

[0027] Test plan:

Embodiment 2

[0049] Example 2 Application effect of water curtain cooling mode in laying hen production

[0050] From June to August 2009 to 2013, more than 1.8 million Hailan and New Roman laying hens aged 35 to 40 weeks were tested in Anyang City, Neihuang, Tangyin, Nanle, Linzhou, Hebi, Huaxian and other places. The promotion and application of the above-mentioned heat protection and cooling are carried out, and the results are shown in Table 1.

[0051] Table 1 Effect of cooling mode on the average production performance of laying hens

[0052]

[0053] The result proves: adopting the cooling scheme of the present invention, the average laying rate of laying hens is 93.20%, the average broken egg rate is 0.31%, the feed-to-egg ratio is 2.10, and the mortality rate is 0.21%, which are basically consistent with the test results, indicating that the water curtain cooling of the chicken house of the present invention The method has good effect in production application and is suitable ...

Abstract

The invention discloses a water curtain cooling method for a chicken house. The method includes: two water curtains are mounted at 1 / 4 positions of two lateral walls on two sides of the front-end wall of the chicken house; four exhaust fans are disposed on the tail-end wall of the chicken house, two exhaust fans are disposed on each of the lateral walls on two sides of the tail-end wall of the chicken house, and the exhaust fans on the lateral walls are 1-2m away from the tail-end wall; water curtain air inlets are formed in the front-end wall of the chicken house, and the temperature of the chicken house is adjusted by turning on the exhaust fans and the water curtains and opening the air inlets according to air temperature, humidity and air quality. By the method which is simple and convenient, laying rate and egg quality can be increased in actual application, and disease incidence can be lowered.

Description

technical field [0001] The invention belongs to the technical field of chicken house environment control, and relates to a water curtain cooling method for a chicken house, in particular to the control of environmental conditions such as temperature, humidity and ventilation of the chicken house. Background technique [0002] At present, with the rapid development of intensive and high-density poultry breeding methods and the intensification of the global climate greenhouse effect, the harm of high temperature heat stress to chickens is becoming more and more serious. The high temperature environment mainly manifests as decreased feed intake, increased drinking water, accelerated respiration, increased body temperature, decreased disease resistance, decreased nutrient digestibility, decreased egg production rate, decreased egg quality, decreased growth rate, and reduced feed utilization. Reduced chicken quality, decreased chicken quality, increased mortality, etc. have cause...
