“…According to the measurements, the new shackling area has better lighting; however, this not result in more bird activity (wing flapping) or more stress (Barbosa et al 2013, Olanrewaju et al 2011, as shown by wingflapping observations and analysis (Tables 1 and 2). The higher variability of the old area is due to the influence of natural lighting.…”

The objective of this study was to investigate if blue lighting could reduce broiler stress and comply with legal labor comfort requirements in a new shackling area of a middle-size processing plant. 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. The old and new areas were video-and audio-recorded during the shackling of 33,850 broilers in each area. Data were statistically analyzed using the non-parametric test of Wilcoxon-MannWhitney (w test).The results indicated 56% reduction in wing-flapping and 3.2% noise reduction in the new area. These results were obtained by increasing 119% lighting at the work stations in the shackling area, allowing workers to handle the birds more carefully, which may improve processing plant productivity. The study demonstrated that it is possible to conciliate better animal welfare with visual comfort for workers in the shackling area.

“…In addition, blue light wave length was shown to stimulate immunity and alleviate stress response (Xie et al, 2008). In addition, exposure of the broilers to blue light just before slaughtering showed potential to be used in modern slaughter houses to offer a comfortable atmosphere (Barbosa et al, 2013). In other taxon, such as fish, blue light was also shown to reduce stress compared to both white and green light (Volpato & Barreto, 2001;Pereira Silva et al, 2012).…”

In the last decades animal production has considerably increased worldwide to sustain an ever-growing human population. Among animal reared for consumption purposes, chickens are undoubtedly one of the most successful, mainly due to their rapid growth rate. The development of broiler farming has been accompanied in recent years by a substantial attention to animal welfare. This study is aimed at assessing the effects of different housing conditions on both feed conversion ratio and mortality of male broiler flocks through a largescale study (more than 100 million birds) involving 977 farms belonging to one major producer. For this, we evaluated nine features of the housing system using a linear model with random effect. The features were: roofing, floor, drinkers, feeders, water source, color curtain color, management, light and ventilation. A total of 3516 poultry flocks were assessed. Positive ventilation, metal and clay roof, dirt floor and owner management were shown to reduced mortality. Concrete floor, negative ventilation, blue curtains, fluorescent lightening, owner management, tap water and well water significantly improved FCR. We discuss our findings in relation with economic constraints and provide advices to encourage farmers using simple devices that will improve both production and chicken survival.

“…However, the development of PSE (pale, soft, exudative) meat has brought problems to the poultry meat-processing industry, and PSE is estimated to generate costs in the poultry industry of over US $200 million in the USA and over US $36 million in Brazil yearly (Oda et al 2003;Owens 2009). Therefore, besides the economical need to overcome these problems, a proper management system to promote the welfare of these birds and to prevent stressful conditions that can lead to the development of meat color have become great challenges to the meat industry (Olivo et al 2001;Barbut et al 2008;Simões et al 2009aSimões et al , 2009bLanger et al 2010;Barbosa et al 2013). PSE meat originates from a rapid decline in pH while the muscle is still warm during the completion of glycolysis, leading to the denaturation of myofibril proteins thus compromising their functional properties (Sosnicki et al1998;Olivo et al 2001) although, as in pigs, there are possible genetic connotations/implications (Paião et al 2013).…”

The aim of this work was to evaluate pH values fall rate in chicken breast meat under commercial refrigeration processing conditions and the development of PSE (pale, soft, exudative) meat. Broiler breast samples from the Cobb breed, both genders, at 47 days of age (n = 100) were taken from refrigerated carcasses (RS) immersed in water and ice in a tank chilled at 0°C (±2). pH and temperature (T) values were recorded at several periods throughout refrigeration in comparison to samples left at room T as control (CS
