Experimental analysis reveals that monochromatic lighting influences blood indices in laying hens, highlighting its potential for optimization.
Key Points
The study aims to explore how different wavelengths of monochromatic light affect the blood parameters and functionality of the hematopoietic system in laying hens.
Four groups of Hy-Line W-36 laying hens were exposed to blue, green, yellow, and red monochromatic lighting.
Haematological indices were measured, including leukocyte, erythrocyte, and thrombocyte counts, haemoglobin concentration, haematocrit, and erythrocyte sedimentation rate.
One-way analysis of variance was used to assess the significance of differences among groups.
Leukocyte count decreased by 45.6% (p < 0.001) when comparing blue light to red light exposure.
Haemoglobin concentration increased by 51.8% (p < 0.001) under red light compared to blue light.
Erythrocyte count rose by 52.2% (p < 0.001) with red light exposure, while the sedimentation rate decreased by 22.6% (p < 0.001).
