“…These results agreed with the report of Mohamed et al (2017) who reported beneficial impact on growth performance of broilers reared under three monochromatic led lights (white, green and blue). This finding is also in line with Senaratna et al (2008) who reported that broilers reared under red colour light showed a tendency to gain higher body weight compared to those reared under white light. Birds in blue, red and green light and troughs had positive effect on total body weight and these are in agreement with the report of Olanrewaju et al (2006).…”

This study was conducted to investigate the effect of light colours and troughs on the growth performance and behaviour of broiler chickens exposed to different colours of light and troughs. A total of 150-day old broiler chicks were randomly allotted into five dietary treatments designated as T1 to T5, with each treatment replicated thrice with 30 chicks each in a completely randomized design. T1 served as control with normal colour of light and trough while birds in T2, T3, T4 and T5 were exposed to blue, red, white and green colors of light and troughs respectively tallying with the colour of trough in each treatment. The study lasted for 8weeks during which the effects of different colours of light and troughs were examined. Data were generated on growth parameters and the bahaviours of the chickens. Results revealed significant differences (p<0.05) across treatments in final weight, feed conversion ratio and water intake with T3 having the least values of mortality 0.00% and highest values of 2.22kg and 63.43g in total weight gain and average daily weight gain, respectively. There were also significant differences (p<0.05) observed in their behaviour across all treatments in the values of feed eating, comfort activity, and lying/sleeping with T1 having the highest value of 0.67% in aggression. It can be concluded that broiler chickens reared under red colour performed better than others while for calmness, blue and green.

“…This temperature was gradually reduced by 2 °C to 3 °C weekly until the final temperature of 25 °C was reached, https://doi.org/10.17221/178/2022-CJAS time (1 h); the average time (s) refers to the average duration of certain behaviour per unit time (1 h), and the maximum time and minimum time (s) indicate that certain behaviour could continue to occur in a unit of time (1 h). The behavioural category and description of broilers were in accordance with those mentioned in Riber et al (2017) and Senaratna et al (2015) (Table 2).…”

This study was conducted to investigate the effects of protease supplementation on the behaviour, slaughter performance, meat quality, and immune organ indices of broilers. A total of 240 one-day-old Arbor Acres broiler chickens were randomly allocated to four treatments, with six replicates per treatment and 10 broilers per replicate. Chickens were fed corn-soybean meal basal diets supplemented with 0, 4, 8, and 12 IU/g of protease.Compared with 0 IU/g of protease supplementation, 12 IU/g of protease increased the average and minimum time of feeding and drinking behaviour (P < 0.05); increased the average, maximum, and minimum time of preening behaviour (P < 0.05); and decreased feeding, walking, and stretching frequency (P < 0.05). pH 24h of breast and thigh muscles had improved (P < 0.05). The shear force of the breast muscle and the cooking loss of the thigh muscle had decreased (P < 0.05). Compared with 0 IU/g of protease, 4 IU/g of protease increased the average and minimum time of lying behaviour (P < 0.05) and decreased stretching, scratching, and aggressive frequency (P < 0.05). The shear force of the thigh muscle and spleen index had enhanced (P < 0.05). Protease can be used as an additive in a broiler diet for production.

“…When exposed to red or red-yellow lights, broilers become more agitated and fearful, whereas blue or green-blue lights lowered their activity . On the other hand, in the case of the Hybro broiler chicken, the weight of the chicken body, feed intake (FI), water consumption patterns, and feed conversion ratio were not significantly affected by red and white color during nighttime (Senaratna, et al, 2008). Meanwhile, a metaanalysis study by Lewis and Morris (2000) found that the growth rate of broiler chickens under white light and red color light exposure was the same and suggested using longer wavelengths for suppressing growth rather than promoting growth with shorter wavelengths.…”

Lighting in poultry production holds notable importance with the advancement and modernization of the industry, as it plays a significant role in the physiology and growth of broiler chickens. Increasing attention has been paid to the impacts of lighting management on growth performance, immune status, and welfare of meat-type chickens. It is essential to have an appropriate lighting regimen that includes the light source, intensity, duration, and wavelength of light to improve broilers’ growth and behavior. By manipulating various physiological, immunological, and behavioral activities, altering the color of light has been acknowledged as a potent managerial strategy capable of mitigating an array of stressors in broiler chickens. Assessing animal welfare is necessary for animal behavior and product quality perspectives. Birds have a unique visual system, and their behavior is primarily mediated by vision. Different monochromatic light regimes can affect feed conversion ratio, modulating broiler chickens’ systematic immune response and aggressive behaviour. With the advancement of lighting technology, new possibilities have emerged to enhance traditional lighting programs in poultry houses. This review integrates recent findings on the use of monochromatic light and its impact on broilers’ welfare, growth, and physiological response.
