We investigated the effects of crest cushions in Runzhou white-crested (RWC) ducks. A total of 322 duck eggs were collected for incubation; 286 eggs were fertilized, and 235 RCW ducks were hatched. All the RWC ducks were weighed after 100 days and counted, and the volume of the crest cushion was measured. The number of crest cushions was positively correlated with the body weight, volume of the crest cushion, and distance from the mouth ( < 0.05). The serum Ca, Mg, Fe, Cu, Zn, and Se contents in the multiple-crest-cushion group were significantly higher ( < 0.05), as were the levels of triglycerides, immunoglobulin A, immunoglobulin G, immunoglobulin M, and immunoglobulin D ( < 0.01). The opposite results were seen for glycosylated low-density lipoprotein ( < 0.01). Propionic acid and acetic acid contents differed significantly between the two groups ( < 0.05), as did butyric acid content ( < 0.01), being higher in the multiple-crest-cushion group. Thus, an increase in the number of crest cushions coincided with a change in various serum biochemical indicators. The number of crest cushions might be involved in regulating various mechanisms of RWC ducks and might have an immunoregulatory effect.
我们研究了嵴垫对润州白冠鸭（RWC）的影响。共收集322枚鸭蛋用于孵化；286枚受精，孵化出235只RWC鸭。在100日龄时对所有RWC鸭进行称重和计数，并测量嵴垫的体积。嵴垫数量与体重、嵴垫体积以及距嘴的距离呈正相关（<0.05）。多嵴垫组血清钙、镁、铁、铜、锌和硒含量显著更高（<0.05），甘油三酯、免疫球蛋白A、免疫球蛋白G、免疫球蛋白M和免疫球蛋白D水平也显著更高（<0.01）。糖基化低密度脂蛋白则相反（<0.01）。两组之间丙酸和乙酸含量差异显著（<0.05），丁酸含量差异也显著（<0.01），多嵴垫组更高。因此，嵴垫数量的增加与多种血清生化指标的变化一致。嵴垫数量可能参与调节RWC鸭的多种机制，并可能具有免疫调节作用。
