摘　　要：试验基于饲粮中添加不同水平维生素D_(3)对种鹅生产繁殖性能、血清激素等的研究,进一步探索其对种鹅蛋品质、血液生化指标、二者相关性及蛋壳超微结构的影响。选择体况相近的34周龄五龙鹅种鹅180只,随机分为6组,每组6个重复,每重复1只公鹅和4只母鹅。6组的维生素D_(3)添加量分别为0、100、200、300、400、500 IU/kg。预试期1周,正试期10周。结果表明:0 IU/kg组蛋壳强度低于其他各组(P<0.01);400、500 IU/kg组蛋壳厚度厚于0、100 IU/kg组(P<0.01);300、400 IU/kg组血清钙含量高于0 IU/kg组(P<0.05);200、300、400 IU/kg组血清磷含量高于0、500 IU/kg组(P<0.01);血清钙含量与蛋重和蛋壳强度、血清磷含量与蛋壳强度呈显著正相关关系;300、400、500 IU/kg组蛋壳乳突层厚度大于0、100 IU/kg组(P<0.01)。可见,适宜维生素D_(3)水平可显著改善蛋壳乳突层厚度;血清钙磷含量与种蛋的蛋重、蛋壳强度呈正相关。开放式饲养下种鹅饲粮中维生素D_(3)的建议添加水平为350~450 IU/kg。The experiment was based on the research of adding different levels of vitamin D_(3) in the diet on the breeding performance,serum hormones,etc.,and further explored its effect on the egg quality,blood biochemical indexes,the correlation between the two and the ultrastructure of the eggshell.18034-week-old breeding geese with similar body condition were selected and randomly divided into 6 groups with 6 replicates in each group,with 1 male and 4 female geese in each replicate.The vitamin D_(3) supplements in the 6 groups were 0,100,200,300,400,500 IU/kg,respectively.The trial period is 1 week,and the trial period is 10 weeks.The results showed that the eggshell strength of the 0 IU/kg group was lower than that of the other groups(P<0.01);the eggshell thickness of the 400 and 500 IU/kg groups was thicker than that of the 0 and 100 IU/kg groups(P<0.01);300,400 Serum calcium content in IU/kg group was higher than 0 IU/kg group(P<0.05);serum phosphorus content in 200,300,400 IU/kg group was higher than 0,500 IU/kg group(P<0.01);serum calcium content There was a significant positive correlation with egg weight and eggshell strength,serum phosphorus content and eggshell strength;the thickness of the eggshell papillary layer in the 300,400,500 IU/kg group was greater than 0,100 IU/kg group(P<0.01).It can be seen that an appropriate level of vitamin D_(3) can significantly improve the thickness of the eggshell papillary layer;the serum calcium and phosphorus content is positively correlated with the egg weight and the strength of the eggshell.The recommended level of vitamin D_(3) for open breeding goose houses is 350~450 IU/kg.
