The null hypothesis was that wing-flapping values were not different between the new and the old areas H: Considering processing line speed and observation intervals, approximately 67, broilers were observed or 33, in the old shackling area and 33, in the new shackling area.

Based on this data, the utilization factor was determined as 0. Protocolo de bem-estarparafrangos e perus [cited Set 13]. This expansion will be gradual, as it involves the other structures breeder farms, hatchery, and broiler farms. The values of wing-flapping are shown in Tables 1 and 2respectively. Therefore, the new area presented more favorable conditions both for broilers and workers in terms of noise. The number of times broilers flapped their wings in shackling line sector A was counted.

Nbbr peaks of sensitivity of three types of cones in the human eye allow the perception of primary colors: In this study, the old shackling area was compared with the new area, where a blue lighting system was designed and implemented according to the regulations.

According to the measurements, the new shackling area has better lighting; however, this not result in aabnt bird activity wing flapping or more stress Barbosa et al. The wing-flapping values obtained in broilers 513 in the old and the new areas are shown in Tables 1 and 2respectively. nbf

The obtained results were slightly different. This step was called “old shackling area”. Because it is a closed environment, temperature and relative humidity were measured in a single spot, near the shackling line. The alternative hypothesis was that there was more wing-flapping in the old area nbf with the new area H: Brazilian Archives of Biology and Technology bnr 5: The decibelimeter recorded instantaneous values every second. Lighting can have a positive or negative influence on broiler welfare because it affects their behavior.

54413 Journal of Poultry Science ;10 Out of the points evaluated, it is the one that best represents lighting where the workers shackle the birds. Koknaroglu H, Akunal T. Lighting for the production and welfare of turkeys. Lighting comfort allows workers to handle birds more carefully, contributing to lower carcass losses.

Meat Science ;43 supl 1: The null hypothesis was that noise was not different between the new and the old areas H 0: The old and new areas were video- and audio-recorded during the shackling of 33, broilers in each area. This has been used to improve the handling of broilers during catching. Light intensity was determined considering the classification of the work in the shackling area as “tasks with limited visual requirement, gross machinery work, and auditoriums” of that regulation.

Using the information on the environment and utilization and depreciation factor, the number of lamps required to obtain the desired light intensity of lux in the new shackling area was calculated as Abntt were some concerns with the 3-month interval between environmental data collection in the old and new areas. World’s Poultry Science ; Lighting was measured in three different points of the video-recorded shackling line beginning, middle, endat birds’ head height.

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, and because the area is relatively high 5.

The second abnh included the design and installation of fluorescent blue lamps with higher lighting intensity to promote better visual comfort to the workers. The method of evaluation applied to the new shackling abht, after the blue lighting system was installed, was identical as that applied in the old shackling area, using the same video-recordings intervals, and humidity, temperature, noise, and luminosity data were 54413 using the equipment described above.

Recording were made to include all possible variables: In addition of the recordings, the following data were measured: 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 of the works in the plant at the time of first collection.

Due to environmental changes and handling to which 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 PSE or dry, firm and dark meat DFD.

Blue lighting in the shackling area of broiler processing plants contributes to reduce bird struggling. Lighting in the shackling area: An alternative for reducing the number of lamps would be to reduce the height where they would be installed, using hanging lamps. Bird activity is reduced as light intensity diminishes. Blue light is recommended during catching, as the visual perception of broilers is greatly impaired, and therefore, they are not distressed.

Meat Science ; Video recordings were made along the mentioned shackling line using a Canon Power Shot S camera always from a fixed position. The lighting of the new area was close to the recommendations of NBR for work stations, of lux. The use of reduced light intensity and blue work clothes are recommended in order not to startle the birds and to transmit calmness Komiyama, Ludtke, and Silveira, The higher variability of the old area is due to nr influence of natural lighting.

Visual pigments, cone oil droplets, ocular media and predicted spectral sensitivity in the domestic turkey Meleagrisgallopavo. In addition, the environment must have good ventilation, low noise, and adequate lighting. As previously mentioned, light intensity was measured at three points 1, 2 and 3according to shackling flow. The legislation on animal welfare has greatly nrb during the last few years.
