摘要: 【目的】研究在基础日粮中添加不同水平维生素D3(VD3)对仔鹅钙磷代谢和免疫机能的影响。【方法】将300只健康、体重均匀的28日龄扬州鹅公鹅随机分成5个处理组,每个处理组6个重复,每个重复10只。对照组饲喂基础饲粮,试验组分别饲喂添加500、1 000、2 000和4 000 IU•kg-1维生素D3的试验饲粮,饲养至10周龄。【结果】基础日粮中添加1 000 IU•kg-1的维生素D3显著提高了10周龄扬州鹅血清钙含量、胫骨钙含量、胫骨强度和血清免疫球蛋白IgG含量(P<0.05);添加2 000 IU•kg-1维生素D3显著提高了血清钙含量(P<0.01)、胸腺指数和血清白细胞介素-4水平(P<0.05);但日粮维生素D3水平对血清磷含量和碱性磷酸酶活性影响不显著(P>0.05)。【结论】日粮中添加适宜水平的维生素D3(1 000—2 000 IU•kg-1)有利于提高扬州鹅仔鹅的钙代谢和免疫机能。

Abstract: 【Objective】The objective of this study is to study the effect of vitamin D3 (VD3) on metabolism of calcium and phosphorus and immune function of Yangzhou goslings.【Method】Three hundred 28-day-old healthy male Yangzhou geese with similar live weight were randomly allocated into 5 treatments. Six replicates per group of 10 geese for each replicate were designed. The control group was fed with a basal diet, while the experimental groups were fed with the experimental diets wich added 500 IU•kg-1, 1 000 IU•kg-1, 2 000 IU•kg-1 and 4 000 IU•kg-1 vitamin D3, respectively, until 10 weeks of age. 【Result】 Adding 1 000 IU•kg-1 vitamin D3 in a basal diet significantly increased serum calcium content, tibia calcium content, tibia strength and serum immunoglobulin IgG content of 10-week-old Yangzhou geese (P<0.05). Compared with the control group, serum calcium content was very significantly increased when adding 2 000 IU•kg-1 vitamin D3 (P<0.01), and thymus index and serum interleukin-4 content were significantly increased at the same vitamin D3 supplemental level (P<0.05). There were no significant effects on phosphorus content and alkaline phosphatase(ALP) activity in serum with different vitamin D3 supplemental levels (P>0.05).【Conclusion】Optimal diet vitamin D3 supplementation (1 000-2 000 IU•kg-1) could increase the metabolism of calcium and the immune function of Yangzhou goslings.
