The high production performance of layer chickens mainly depends on four factors: First, there must be high-quality varieties. This includes not only the genetic advantages of the breed, but also diseases that do not have vertical transmission; the second is to have high-quality feed, that is, to meet the different growth of chickens. The nutritional requirements at the stage require a reasonable and scientific formula, and the quality of the raw materials is reliable. The third is to have a scientific immunization program to maximize the potential for chicken production. The fourth is the husbandry and management because chickens, feed, and immunization programs can be artificial. The selection, once the three are determined, whether the laying hens can exert their maximum potential, the feeding and management is the most important during the whole breeding period. The environmental factors mainly refer to temperature, humidity, light, air quality, and noise.

Temperature effect

The suitable production temperature for laying hens is 16°C-27°C. In northern China, the usual temperature is usually -10°C-35°C. Therefore, some technical measures need to be taken to ensure a suitable temperature environment. Experiments have shown that for laying hens, as long as the winter broiler house is properly designed and constructed, depending on the chicken's own body heat, the proper temperature environment can be basically guaranteed. Even if it is a short-term low-temperature weather, the temperature in the broiler house should not be lower than 5°C. The chicken body can also achieve body temperature balance through its own regulatory system and increased intake of high-energy feed.

From a physiological point of view, because the body does not have sweat glands and the body covers feathers, the way to remove heat is mainly to accelerate the excretion to take away part of the heat by increasing the respiratory rate and the amount of drinking water, and these two methods of heat removal are insignificant in hot weather. . Therefore, it is safe to reduce the temperature of the house.

Humidity effect

The effect of humidity on egg production in laying hens depends on changes in temperature. According to reports, the relative humidity of over 85% in winter has an adverse effect on egg production. The upper limit temperature (constant) required for laying hens to produce eggs decreases as the humidity increases. When the temperature is higher than 33°C and the relative humidity is 30%, no matter how the diet fits, the egg production cannot be reduced.

In the case of constant temperature, the humidity is too high, air dust, hair debris, feed residue particles can be inhaled into the respiratory tract by chickens, stimulate the mucous membranes, such as entrapment of pathogenic microorganisms in the particles, can make chicken infection Causes cough, bronchitis, etc. If the humidity inside the house is large, the particles can absorb the moisture of the air, and can also absorb a part of ammonia and hydrogen sulfide. Such mixed particles can also stimulate the respiratory mucosa and cause mucosal damage. Light effects

Light color type. Under the same light intensity, the effects of various light colors on laying performance of laying hens were different. Red light had the best effect, followed by white light, and purple had almost no effect.

Light intensity. The light intensity required for laying hens ranges from 0.1 lux to 5 lux. Eggs can be layed normally at 0.1 lux, 0.2 lux can increase egg production, and 2.0 lux make the egg production reach a very high level, exceeding 5 lux, increasing production. The effect of egg volume is not obvious. In addition, when the light intensity is too strong, feathers, toes, cavities, and nervousness are easily caused, which affects the production performance and feed utilization. Therefore, it is generally believed that the light intensity required for the laying of laying hens is 5 lux. Is 3 watts - 4 watts per square metre of chicken coops is appropriate, light bulbs should be more, the best brightness of 40 watts.

Lighting time. 1. The optimal illumination time for laying hens in the pre-laying period is 16 hours and the later period is 16.5 hours. Changes in conditions such as temperature and feed, although affecting egg production, do not change it fundamentally. Only the change of the illumination time is the decisive factor for the production season of laying hens. 2. The change of the illumination time is more important than the absolute length of the illumination on the sexual maturity of laying hens. Under the condition of constant 22 hours, 6 hours of light increase (from 6 hours to 22 hours) and decrement (from 22 hours to 6 hours), the earliest increase in illuminance is earliest, followed by constant long illumination, followed by constant short illumination. The worst case is decreasing the lighting time. 3. During the production of eggs, the influence of the constant light time on the production performance is very important. The long and short illumination time and the unstable light time setting not only reduce the egg production rate, but also increase the double yellow eggs and non-yellow eggs. .

Air quality impact

Ammonia effect. As most of the ammonia gas is distributed on the top of the house, there is no sunroof in the house. As the ammonia gas volume increases, the impact on the production performance of laying hens will also increase.

Hydrogen sulfide effect. Most of the hydrogen sulfide starts from the bottom chicken cage. Because the digestive tract of the chicken itself is short, the digestibility of feed is only 80%. When the layers of chickens feed on protein-rich feed and indigestion, a large amount of feed residues can be discharged from the intestine. Some of these are sulfur-containing proteins. These materials are anaerobic. A large amount of hydrogen sulfide is decomposed. When there are more damaged eggs, the content of hydrogen sulfide in the air increases significantly. At this time, hydrogen sulfide stimulates the respiratory mucosa, causing conjunctivitis, manifesting tearing, rhinitis, bronchitis, etc., weakening the chicken's constitution, reducing disease resistance, and increasing mortality. .

Carbon dioxide effects. The carbon dioxide in chicken coops is mainly produced by breathing. Carbon dioxide itself is not toxic to chickens. Its harm is mainly caused by lack of oxygen, causing chronic poisoning, manifested as apathetic, loss of appetite, and physical decline. When the concentration of carbon dioxide is further large, it is apparent that the respiration is accelerated, the coma is present, and death is suffocated.

Noise effect

Experiments have shown that noise of 90 dB -100 dB can cause temporary egg production decline in laying hens, and can gradually adapt to the progress. However, the noise that continues to exceed this intensity will further reduce egg production. 130 dB of noise can cause the chicken to lose weight and even die. However, low-intensity light music can keep the flock quiet, reduce the incidence of frightening, and promote the sexual maturity of the chicks, thereby increasing the egg production rate of the flock.

Aluminum Foil Anti Slip Tape

Aluminum Foil Anti Slip Tape

Aluminum foil backed anti slip tape is a special anti slip tape that is designed for uneven surfaces and high traffic areas, it can be used instead of 3M 500 series, such as 3M 510 and 3M 530. The aluminum foil backing make the tape much more durable than general anti slip tape, and it has no memory so that it can remain its shape and conform to uneven surfaces. The aluminum foil has no stretchability which is different from PVC or PET plastic based, when a plastic stretches it wants to revert to its original state so will lift from an irregular substrate. It is widely used for stairs, ladders, loading ramps, platforms, diamond plating, flat surfaces with rivets or screw heads.
