“…Whereas, significant differences were observed in the relative weights of the thigh, wings, and neck parts in the seventh week, especially for treatment T3 (17 hours of light: 3 hours of darkness: 1 hour of light: 3 hours of darkness) in which the relative weight of these pieces increased compared to the control treatment, and the reason may be due to the significant decrease in relative weight chest part in this treatment and may have had a role in influencing the growth of other parts. These results agreed with Abreu et al (2011b), who indicated that the use of intermittent lighting had a significant effect on the relative weight of the thigh. As for the relative weight of abdominal fat, the same table indicates that there are no significant differences when using different lighting systems, and these results are in agreement with those obtained by Olanrewaju et al (2012Olanrewaju et al ( -2018.…”

“…Lighting programs can affect many aspects of avian physiology, welfare, behavior, and other factors, including blood chemistry, ocular development, and behavioral rhythms (Olanrewaju et al, 2006(Olanrewaju et al, , 2013Schwean-Lardner et al, 2013). Abreu et al (2011b) reported that carcass and thigh weight were heavier when using the intermittent light program. As well as improving the quality of the carcass (Zdenka et al, 2011).…”

during the period from 22/9-10/11/2019 (for a period of 49 days). This study aims to demonstrate the effect of different systems of lighting on production performance, leg abnormalities, total mortality rate and some microbial traits in broiler chickens. 300 unsexed Ross308 chicks were used in the study at one day age with an average initial weight of 37.5 g. They were randomly distributed to five experimental treatments with three replicates for each treatment. Chicks were fed on starter diet for the first three weeks of age, and finisher diets for the fourth, fifth, sixth and seventh weeks of bird age. All birds switched to continuous lighting (24 hours light) during the first week of age. On the eighth day, the experiment was divided into five treatment ,The first program was Tc (control) 24 hours of light, the second T1:18 hours of light: 6 hours of darkness, and the third T2: 19 hours of light: 2 hours of darkness: 1 hour of light: 2 hours of darkness and the fourth T3:17 hours of light: 3 hours of darkness :1 hour of light: 3 hours of darkness, 5 hours of darkness, T4: 15 hours of light: 4 hours of darkness: 1 hour of light: 4 hours of darkness. (Up to the age of 6 weeks) and at the seventh week, all birds were exposed to continuous lighting for 24 hours of light. The results indicated that there were no significant differences in dressing yield with out and with edible organs at 6,7 weeks. While significant differences (P <0.05) were observed in the relative weight of the thighs and wings parts in the treatment T3 compared with the control Tc treatment at the seventh week of age and a high significant superiority (P <0.01) for the treatment T3 in the relative weight of neck cutter for the same age, Whereas, the control Tc treatment was significantly superior (P <0.05) in the relative weight of the liver compared to the T1 treatment at the sixth week of age. Treatment T2 (P<0.01 and P <0.05) was significantly compared with all trial treatments in pH value in crop, duodenum and ileum at 7 weeks of age. A significant increase (P <0.05) was observed in the T2 treatment compared to the control treatment in the relative weight of thymus gland at the seventh week of age, and highly significant (P <0.01) in the T3 treatment compared to the control treatment in the antibodies directed against Newcastle disease. Conclusion: It is concluded from this study that intermittent lighting programs Improved immune system function and reinforcement Production of antibodies against Newcastle disease and improved pH value of the digestive system.

“…Cave et al (1985) reported that males raised under IL had higher abdominal fat content than female broilers; however, other report indicated that the abdominal fat pad contents of broilers reared under IL were significantly less than those of broilers exposed to CL (Buyse et al, 1996). In contrast, Abreu et al (2011) did not observe differences in abdominal fat deposition between IL and CL programme. Based on these research results, it could be inferred that abdominal fat content might be affected by several factors, such as lighting time, photoperiod, sex, age, and breed.…”

“…Zdenka et al (2011) observed that an IL regime is justified from the standpoint of carcass quality improvement. In addition, Abreu et al (2011) found that IL programme promoted the highest drumstick and thigh yields. Cave et al (1985) reported that males raised under IL had higher abdominal fat content than female broilers; however, other report indicated that the abdominal fat pad contents of broilers reared under IL were significantly less than those of broilers exposed to CL (Buyse et al, 1996).…”

The objective of this study was to investigate the effects of intermittent lighting (IL) on broiler growth and slaughter performance as well as serum biochemical and tibia parameters. Two hundred and eighty 7-d-old Ross 308 broilers were selected and reared from 8 to 42 d under IL photoperiods of either 2 hours of light:2 hours of dark (2L:2D) or 4 hours of light:4 hours of dark (4L:4D), or under continuous lighting (CL). On day 42, body weight of broilers raised in the 4L:4D photoperiod was significantly increased compared to those reared in the 2L:2D photoperiod. The average daily feed intake (ADFI) of broilers in IL was significantly less than broilers in CL. The feed conversion of broilers raised in the 4L:4D photoperiod was significantly more efficient than broilers in CL. The intestinal tract weight was greater in birds raised in the 4L:4D photoperiod compared to birds in CL. Similarly, the eviscerated yield with giblet and eviscerated carcass weights in birds reared in the 4L:4D photoperiod were significantly higher than corresponding weights observed in broilers raised in CL. Serum total protein concentration was distinctly higher in birds raised in the 4L:4D photoperiod than that in the 2L:2D photoperiod. In addition, the bone elastic modulus of birds reared in the 4L:4D photoperiod was greater than measurements observed in the 2L:2D photoperiod. Accordingly, we concluded that the 4L:4D photoperiodic lighting schedule was superior to both the 2L:2D photoperiod and CL in broiler production.

“…These findings partially agree with those reported by Farghly and Makled (2015) who they found that flash lighting significantly affected on liver percentages. And, Abreu et al, (2011) who showed that lighting programs did not affect the heart, liver, gizzard, and abdominal fat percentages.…”

he present study was designed to investigate the effect of light regimens and vitamin D3 levels on growth performance and some carcass traits of broiler chickens. Two hundred and seventy birds were randomly assigned in factorial design (3x3). Three light regimens (24 hrs continues light, 12 hrs continues with 12 hrs flashlight and 24 hrs flashlight) and three vitamin D3 levels (0, 200 and 400 IU). Nine treatments of 30 birds each (three replicates of 10 birds each). The birds were housed in floor pens from day one till six weeks of age. Feed and water were available ad lib. and all conditions were the same during the experimental period. The results showed that significantly affected body weight, daily weight gain and feed conversion ratio. In addition, birds reared under continuous with flashlight and feed with 200 IU Vit. D3 had significantly (P≤0.05) better body weight, daily weight gain , feed conversion and some carcass traits compared to the other groups. Finally, birds reared under continuous with flashlight and feed with 200 IU Vit. D3 was better than the other groups and was recommended to the poultry producer.
