Therefore, a required average light intensity of lux was determined NBR Revista Avicultura Industrial The behaviour of broiler chickens in different light sources and illuminances. Data collection between the old and the new area was carried out as close as possible, but It was not possible to be simultaneous because jbr the works in the plant at the time of first collection.

When all cones are simultaneously stimulated, the brain preceives the light as white. The peaks of sensitivity of three types of cones in the human eye allow the perception of primary colors: Environmental noise was measured using a decibel nbrr every second, simultaneously to 13 daily videorecordings. The company has a feed mill, a hatchery, breeder sbnt, and contracted farmers, and sells chicken products to the south, southeast, north, and northeast regions Brazil, as well as exports them to Asian countries.

This is called the method of average lumen lighting and it is the most adequate for routine work in a fixed working station. How to cite this article.

Lighting design of the new area try to conciliate the reduction of broiler stress as measured by agitation with better working conditions and better lighting comfort for the workers, according to regulation NBR of ABNT. World’s Poultry Science ; The study demonstrated that it is possible to conciliate better animal welfare with visual comfort for workers in the shackling area. In addition, the environment must have good ventilation, low noise, and adequate lighting.

Abnf addition of the recordings, the following data were measured: The method of evaluation applied to the new shackling area, after the blue lighting system was installed, was identical as that applied in the old shackling area, using the same video-recordings 513, and humidity, temperature, mbr, and luminosity data were recorded using the equipment described above.


Noise results as measured in the old and new area are discussed below. Lewis PD, Morris T. Spectral sensitivity of the domestic fowl. This step was called “old shackling area”. The legislation on animal welfare has greatly developed during the last few years.

The second step included the design and installation of fluorescent blue lamps with higher lighting intensity to promote better visual comfort to the workers. The wing-flapping values obtained in broilers shackled in the old and the new areas are shown in Tables 1 and 2respectively.

In the United Kingdom, for instance, each processing plant must have a worker trained on bird welfare to oversee unloading, lair age, and slaughter ACP, This was particularly the case of point 1, where average lighting level increased Using controlled and reduced lighting during catching minimizes possible physical and 541 emotional damages during this operation Kristensen et al. Lighting was measured in three abny points of the video-recorded shackling line beginning, middle, endat birds’ head height.

It should be noted that better lighting allows better worker performance, as they will have less problems in shackling the broilers because they can see better what they are doing, which will also result in less broiler trauma and bruises. Sector A included the distance between the last shackling station and the entrance to the stunner. This could be extrapolated to the shackling sector of broiler processing plants, where reduced lighting with blue light is also recommended. Due to environmental changes and handling to abt broilers are submitted during shackling, stress is more intense and it is expressed as struggling, which may lead to processing losses, including broken bones, bruises, and meat quality defects like pale, soft, and exudative meat 513 or dry, firm and dark meat DFD.

The number of times broilers flapped their wings in shackling line sector A was counted. Visual pigments of chicken and pigeon.


Color perception of poultry is similar to that of humans, except for short-wave light.

After data in the old area was collected, the nnr lighting of the new shackling area was designed, and measurements were made. Recording were made to include all possible variables: Lighting in the shackling area: Quality attributes of animal products include good production practices and their association with animal welfare and abnh wellbeing, as well as food safety and environmental aspects, which determine the ethics of animal production UBA, Computers and Electronics in AgricultureThe use of reduced light intensity and blue work clothes are recommended in order not to startle aabnt birds and to transmit calmness Komiyama, Ludtke, and Silveira, Machine vision to identify broiler breeder behavior.

Video recordings were made along the mentioned shackling line using a Canon Power Shot S camera always from a fixed position. This number is relatively high when compared with the number of conventional lamps that would be required because the light flow of the blue lamps available in the market is only lumen, 513 because the area is relatively high 5. Out of the points evaluated, it is the one that best represents lighting where the workers shackle the birds.

An intermediate lighting intensity at the work stations was applied. Considering processing line speed and observation intervals, approximately 67, broilers were observed or 33, in the old shackling nbg and 33, in the new shackling area. The obtained results were slightly different.

The reduction of noise in the new area was 2. Lighting is widely used for the manipulation of the behavior of meat-type poultry Nixey, ; Lewis et al. This expansion will nr gradual, as it involves the other structures breeder farms, hatchery, and broiler farms. Meat Science ;43 supl 1:
