Abstract
OBJECTIVE: In the study, the effects of different colour LED lighting on the physiological and behavioural characteristics of pregnant rats, mother rats, and their offspring were investigated using an experimental model consisting of primiparous (first-time delivering) rats. METHOD: In the study, 24 pregnant rats (Wistar Albino) were included in 4 groups, each including. The rats were placed in 4 light cabinets (White, Red, Blue, Yellow). During pregnancy and the postpartum period, the body weights of the pregnant/mother rats and their offspring, the weight gain of the pregnant rats, the daily feed and water consumption, blood glucose levels, skin thicknesses, and the behavioural characteristics of the pregnant rats and their offspring were assessed. RESULTS: Feed and water consumption was highest in the Red group (0.51 ± 0.06 ml/BW (g)/day). Significant differences were determined between the rat groups in terms of their blood glucose levels, skin thicknesses, and the results of the behavioural characteristics on the pregnant and offspring rats (p < 0.05). CONCLUSION: Red light had a weight-increasing effect on pregnant rats, while blue light had an oedema-preventing effect and a weight-increasing effect on the offspring.
