Effect of Various Monochromatic LED Light Colors on Performance, Blood Properties, Bone Mineral Density, and Meat Fatty Acid Composition of Ducks

Abstract

Two experiments determined the effects of various monochromatic light emitting diode (LED) light colors on performance, blood properties, bone mineral density, meat quality properties, and fatty acid composition of ducks. In Experiment 1, 720 1-d-old Cherry Valley ducklings were divided into four light treatments (six replicate pens/treatment; 30 ducks/pen) and were assigned to 1) yellow (Y), 2) green (G), 3) blue (B), or 4) control white (fluorescent lamps). In Experiment 2, six LED light treatments with four replicates were assigned as blue (PB), bright blue (BB), sky blue (SB), greenish blue (GB), green (PG), and fluorescent white as a control treatment. In Experiment 1, G light increased body weight and weight gain compared with the control and Y light during the first 21 d. During d 22-42, weight gain increased in the G and B treatments (P＜0.034). Body weight and weight gain were increased under the G light treatment (P＜0.036) in Experiment 2. Blood values were not influenced by the light treatments but serum cholesterol level decreased under the PB treatment (P＜0.015) compared to PG treatment. Whole blood viscosity at a shear rate of 1 per second decreased significantly under the PG treatment than that of control W treatment. Ducks reared under GB and PG light had increased monounsaturated fatty acids and unsaturated fatty acids/saturated fatty acids by altering the fatty acid composition in muscle. These results suggest that monochromatic PG and GB light color increased growth performance, blood properties, and muscular fatty acid composition, while providing similar bone and meat properties in Cherry Valley ducks.

Effects of continuous white light and 12 h white-12 h blue light-cycles on the expression of clock genes in diencephalon, liver, and skeletal muscle in chicks

“…Previous studies showed that continuous blue light does not affect food intake in chicks (Prayitno et al, 1997;Hassan et al, 2014;Seo et al, 2015). In the present study, chicks eat food under the blue light (Fig.…”

“…Similarly, Pan et al [8] stated that while the light with a short wavelength (blue and green) induced the growth of broilers in early periods, the light with a long wavelength (yellow) induced the growth in the late period. It was found that every 100 nm (455 to 620 nm) increase of light's wavelength in early period decreased live weight by 15.4 g, every 100 nm of increase in the late period elevated live weight by about 16.4 g. Hassan et al [17] also reported that the highest body weight and weight gain of duck were obtained in green light treatment compared with the white, yellow and blue lights during first 21 days. During d 22-42, weight gain increased in both the green and blue treatments in a like manner.…”

“…The superiority of LEDs to other sources of light increases the use of this light source in poultry houses day by day [5] . Because perception levels of LED lamps at various wavelengths are different, a lot of researchs in broiler [1,9,25] and less in other poultry species [10,17,23] were determined to have different effects on performance in recent years, however, no information could be reached in partridge species. Investigatings in the present study showed that green LEDs increase feed intake of partridges significantly (Table 2).…”

“…Density, wavelength, and source of the light are known to be the important environmental factors that have an effect on behaviors and physiology of poultry animals [13,14] . It was found for laying hens that red light decreased aggressiveness [4] , green light relieved and rested broilers [15] , white light elevated plasma corticosterone levels in songbirds [16] , also color of the light are effective on blood biochemistry such as glucose, triglyceride, cholesterol, uric acid [12,17] and immunological parameters [11,18] .…”

Assessment of Light Source and Dietary Energy in Relation to Carcass and Bone Characteristics of Broiler Chicks

“…Thus, many broiler producers have switched from fluorescent lamps to LED lighting devices, due to its higher efficiency of energy usage and its availability in diverse wavelengths and/ or colors (Huber-Eicher et al, 2013). The impact of various light sources, photoperiods, light intensities, monochromatic light colors, combined light colors and different wavelengths of light on boiler performance, has been extensively studied by many researchers (Downs et al, 2006;Cao et al, 2008and Hassan et al, 2012.…”
