Abstract Magang geese with 0 days old were used to investigate the influences of different light colors on growth performance and some hormones in this study. The white LED light(control group), 480 nm blue LED light and 660 nm red LED light was used in the experiment. In the experimental 7, 35 and 63 days, the body weight and body measurements of geese were recorded, and plasma samples were collected to measure related hormone levels. The results showed that in the late growth stage of geese, the body weight in the blue light was significantly lower than those in red lights(P<0.05). For body measurements, only the breast depth was extremely significantly different throughout the whole experiment period(P<0.01). Extremely significant differences were found in body slope length at day 7, back width at day 35, and shank circumference at day 63 between the three light treatment groups(P<0.01). Adrenalin(ADR) in red light was significantly lower than those in other two groups while growth hormone(GH), insulin-like growth factor 1(IGF-1) and thyroid hormone(T3) had no significant differences among these three groups(P>0.05). The results showed that the sensitivity of geese to blue light and red light was different. In the late growth stage, blue light inhibited the growth performance of geese while red light promoted the growth performance compared with white light.
