不同光色对马岗鹅生长发育的影响

为研究不同波长的光处理对肉鹅生长性能及相关激素的影响，以０日龄马岗鹅为研究对象，分别采用白色（对照）、４８０ｎｍ蓝色和６６０ｎｍ红色ＬＥＤ灯照明，在第７、３５和６３天记录鹅的体质量和体尺，并翅下采血检测血清中的相关激素水平．结果发现，在第６３天，蓝光处理鹅体质量显著低于红光组（Ｐ＜０.０５）；处理间体尺指标在整个试验期只有胸深差异极显著（Ｐ＜０.０１），试验第７天的体斜长、第３５天的背宽和第６３天的胫围差异极显著（Ｐ＜０.０１）．红光组肾上腺素（Ａｄｒｅｎａｌｉｎｅ，ＡＤＲ）水平显著性低于其他两组，血清生长激素（Ｇｒｏｗｔｈ ｈｏｒｍｏｎｅ，ＧＨ）、胰岛素样生长因子１（Ｉｎｓｕｌｉｎ ｌｉｋｅ ｇｒｏｗｔｈ ｆａｃｔｏｒ １，ＩＧＦ-１）和三碘甲状腺原氨酸（Ｔｒｉｉｏｄｏｔｈｙｒｏｎｉｎｅ，Ｔ３）各处理间差异不显著性（Ｐ＞０.０５）．研究结果表明，鹅在不同时期对蓝光和红光的敏感性不同，与白光对比，在试验后期蓝光抑制鹅生长，红光促进鹅生长．

Influence of light color on growth performance in Magang geese

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.
