ABSTRACT

A 28-day experiment was conducted to evaluate the effects of dietary vitamin A (VA) levels on intestinal morphology and immune performance of goslings. Healthy, one-day-old goslings (360) of similar body weight were randomly divided into six groups fed diets supplemented with 0 (A), 3 000 (B), 6 000 (C), 9 000 (D), 12 000 (E), and 15 000 (F) IU/kg VA. Compared to group A, villus height in group D, as well as villus width and crypt depth in groups C and D were increased in the duodenum (quadratic effect, P < 0.05); villus height and villus width in groups B, C, D and E, and crypt depth in groups C and D were increased in the jejunum (quadratic effect, P < 0.05); villus height and villus width in groups C and D, and crypt depth in groups B, C, D, E and F, as well as muscular layer thickness in group D were increased in the ileum (quadratic effect, P < 0.05). Serum immunoglobulin A in groups B, C, D and E, and serum immunoglobulin G levels in groups D and E were higher than in group A (quadratic effect, P < 0.05). Serum interleukin-1 (quadratic effect, P < 0.05) and interleukin-6 (linear and quadratic effect, P < 0.05) levels in groups D and E, and serum interleukin-2 level (quadratic effect, P < 0.05) in group C were higher compared to group A. In conclusion, dietary supplementation with 6 000–9 000 IU/kg VA improved intestinal morphology and immune performance of goslings.

饲粮中添加维生素A对雏鹅肠道形态和免疫性能的影响

摘要：本试验旨在研究饲粮维生素A (VA)水平对雏鹅肠道形态和免疫性能的影响。将360只体重相近的1日龄健康雏鹅随机分为6组，分别饲喂添加0 (A)、3, 000 (B)、6, 000 (C)、9, 000 (D)、12, 000 (E) 和15, 000 (F) IU/kg VA的饲粮。D组十二指肠的绒毛高度、C D组十二指肠的绒毛宽度和隐窝深度均高于A组 (二次效应， P < 0.05)。B、C、D和E组空肠的绒毛高度和绒毛宽度以及C和D组空肠的隐窝深度均高于A组 (二次效应， P < 0.05)。 C和D组回肠的绒毛高度和绒毛宽度，B、C、D、E、F组回肠的隐窝深度和D组回肠的肌层厚度均高于A组（二次效应，P < 0.05）。 B、C、D、E组血清免疫球蛋白A含量及D、E组血清免疫球蛋白G含量均高于A组（二次效应，P < 0.05）。 D、E组血清白细胞介素-1 (二次效应，P < 0.05)、白细胞介素-6 (线性和二次效应，P < 0.05) 含量及C组血清白细胞介素-2含量 (二次效应，P < 0.05) 均高于A组。由此可见，饲粮中添加 6, 000 ~ 9, 000 IU/kg VA能够改善雏鹅肠道形态、提高免疫性能。
