    In this study, it was aimed to investigate the effects of red lighting on blood and milk melatonin (MLT) levels, and milk quality. The experiment was carried out on 6 lactating Holstein Dairy cows, which were being reared at the Hümeyra Özgen Research and Application Farm, affiliated to Selcuk University Faculty of Veterinary Medicine. After a control period of 15 days in which night lighting was not applied (control group), night lighting was provided by LED bulbs emitting red light with a wavelength of 652 nm during the following 15-day trial period (experimental group). On days 5th, 10th and 15th days of the control and experimental groups, milk and blood samples were taken at the 06:00 am and at 06:00 pm.Serum and milk melatonin concentrations in the morning of the control, on days 5th, 10th and 15th; were 8.64±1.4, 7.02±0.97, 8.71±2.3, and 5.01±0.92, 5.23±0.35 , 3.93±0.81pg/ml, respectively while control evening group were respectively 8.59±1.8,7.53±2.14,8.35±0.94, 6.91±1.73, 6.8±1.27. It was obtained as 3.67±0.97 pg/ml. Serum and milk melatonin levels in the trial morning group were 10.93±2.06, respectively, on the same days; 15.37±2.6; 11.25±1.71 and 2.97±0.64; 5.7±1.06; While it was measured as 3.33±0.73 pg/ml, it was 14.83±3.11 in the trial evening group; 14.5±3.57; 12.95±4.09 and 4.42±0.61; 2.51±0.56; It was obtained as 2.48±0.79 pg/ml. As a result, it was observed that serum and milk melatonin levels and milk parameters were not adversely affected in the use of red LED lamps (652 nm) at night for 12h, it was thought that there was no inconvenience in using them in indoor shelter lighting at night.
