“…In the study, the neck (P < 0.001) and tail-area feather scores of layers were better in the LED group than in the FLO group (P < 0.0001). Aggressive behaviors, such as feather pulling and pecking of layers, increased under high light intensity [27]. In the study, the effects of cage tier on the body-feather scores of layers were similar at 25 weeks of age (P > 0.05), but the mean feather score values of layers were best in cage tier IV at 45 weeks of age (P < 0.05).…”

The aim of this study was to determine the effects of lighting type [light-emitting diode (LED) and compact fluorescent (FLO) light] and cage tier on welfare traits such as feather score, body and comb wounds, bumble foot and footpad dermatitis, beak damage, keel bone deformity, finger damage, aggressive pecking behavior, and the avoidance distance test (ADT) in laying hens reared in an enriched cage system. A total of 400 layers were used to determine these traits at 25 and 45 weeks of age. A total of 80 layers were used to determine tonic immobility (TI) duration and induction number. The dust accumulation rate (DAR I and DAR II) was recorded to determine the activity of layers under different lighting sources at 25, 35, and 45 weeks of age. The highest DAR I and DAR II were determined in the FLO group at 35 and 45 weeks of age (P < 0.05). The worst comb wound and highest ADT were found in the FLO group at 25 weeks of age (P < 0.05). In the FLO group the mean feather score, comb wound, and finger damage were worse than in the LED group (P < 0.01). In addition, aggressive pecking behavior (P < 0.01) was observed more in the FLO group at 45 weeks of age (P < 0.05). The breast and vent feather scores (P < 0.001), mean body feather score, comb wound, and footpad dermatitis of hens at 45 weeks of age (P < 0.05) were worse in lower cage tiers. In conclusion, using LED light in poultry houses helps to increase some of the welfare parameters. Cage tier significantly affects the welfare parameters, and this effect is clearer around 45 weeks of age in layers.

“…It was recorded previously (23), where, initial body weight (IBW) of ducks was weighed at the beginning of experiment (2 nd weeks age) and weekly until 10 th weeks age, also feed residues and thus average feed intake (FI) were recorded weekly. Average body weight gain (ABWG) was calculated by subtracting body weight between two successive weeks.…”

“…At the end of the experimental period, blood samples had been collected randomly from 15 ducks/group, at morning to overcome the circadian variation in hormone level (23). Blood samples were obtained from wing vein into heparinized tubes, centrifuged at 4000 rpm for 15 min to obtain blood plasma, which stored on -80°C for evaluating the cortisol level, as one of stress indicating hormones (24).…”

Ducks spend their entire life in contact with the litter material, thus the management strategies should focus on what is the best for ducks welfare and growth performance. Herein, the main object of the present study was assessing the effects of different litter materials on the ducks' welfare and growth performance. Four groups of ducks (24 duckling for each) were kept on four types of bedding materials, sawdust, plastic slatted floor, sand and without. The present study revealed several changes in duck's behaviors due to different bedding materials, where the most frequencies of maintenance behaviors (feeding, drinking, idling, preening) were significantly (P<0.05) higher in plastic slatted in comparing to other materials the highest significantly in plastic slatted litter and the lowest in non-bedding litter. Moreover, the ducks reared under sawdust floor revealed the highest frequency of foraging behavior (11.48 bouts/hour). While, feather pecking and aggression were the highest in non-bedding material (74.4, 5.51 bouts/hour, respectively). The hygienic conditions inside the non-bedding floor was the worst due to increase levels of ammonia and carbon dioxide (12, 0.97 Cm 3 /Litter, respectively). The ducks reared in plastic slatted floor were the best in growth performance with good signs of soundness. In non-bedding floor, the environmental stress revealed in the increase the level of plasma corticosterone hormone with bad signs of soundness. This study confirms importance of bedding materials in rearing of ducks, especially under plastic slatted floor.

“…Artificial light is one of the critical environmental factors affecting bone calcification in poultry. In a specific range of light intensity, the activity of broilers was positively correlated with light intensity, which increases the pressure and load on bones and promotes bone development ( Mohammed et al, 2016 ; Škrbić et al, 2019 ). The light can cause changes in some skeletal metabolic pathways, such as calcium and phosphorus metabolism ( Tabeekh et al, 2016 ).…”
