The supplemental feeding of wildlife is a worldwide phenomenon. The most widespread and socially accepted example is bird feeding. Commercial hedgehog (Erinaceus europaeus L.) diets are readily available in Switzerland. To test the hypothesis that commercial hedgehog diets are nutritionally inadequate, the following parameters (as taken from the label) of five commercial diets (three dry and two wet) were compared to the natural diet of E. europaeus: List of feed materials, crude ash (CA), crude protein (CP), crude fibre (CF), ether extract (EE) and nitrogen-free extracts (NfE). To test the second hypothesis, that feed labels of commercially available hedgehog diets in Switzerland are in accordance with Swiss and European law, the following parameters were assessed: Type of feed, net quantity, moisture content, instructions for proper use, list of the feed materials and claims. In all dry diets, the first ingredient was cereals (38.8%–50%), whereas in both wet diets, it was meat and meat by-products (51% in one product). Only one product had a CP content comparable to that of the natural diet and four products had a higher NfE content. Overall, the wet products were more comparable to the natural diet, especially regarding CP and NfE content. Of the five examined diets, three were labelled as complete feeds and two as compound feeds. The label analysis revealed inaccuracies and possible misleading information on two products. In conclusion, the use of commercial dry hedgehog diets should be discouraged as they do not resemble the natural diet of E. europaeus and are likely nutritionally inadequate. The commercial wet hedgehog diets should only be used supplementary. The feed labels of commercially available hedgehog diets were not always in compliance with Swiss and European law. The public should be educated about feeding E. europaeus and the risks of commercial diets for wildlife.

喂养欧洲刺猬 (Erinaceus europaeus L.)——野生动物商业饮食的风险

野生动物的补充喂养是一个世界性的现象。最普遍和社会接受的例子是喂鸟。商业刺猬 ( Erinaceus europaeus L. ) 的饮食在瑞士很容易买到。为了检验商业刺猬饮食营养不足的假设，将五种商业饮食（三种干和两种湿）的以下参数（取自标签）与E的天然饮食进行了比较。 欧洲人：原料清单，粗灰分（CA）、粗蛋白（CP）、粗纤维（CF）、乙醚提取物（EE）和无氮提取物（NfE）。为了检验第二个假设，即瑞士市售刺猬饲料的饲料标签符合瑞士和欧洲法律，评估了以下参数：饲料类型、净含量、水分含量、正确使用说明、饲料清单材料和索赔。在所有干粮中，第一种成分是谷物（38.8%–50%），而在湿粮中，它是肉类和肉类副产品（一种产品中的 51%）。只有一种产品的 CP 含量与天然饮食相当，而四种产品的 NfE 含量更高。总体而言，湿产品与天然饮食更具可比性，尤其是在 CP 和 NfE 含量方面。在五种检查的饮食中，三个被标记为完全饲料，两个被标记为复合饲料。标签分析揭示了两种产品的不准确和可能的误导信息。总之，不应鼓励使用商业干刺猬饮食，因为它们与刺猬的自然饮食不同。乙。 europaeus并且可能营养不足。商业湿刺猬饲料只能作为补充。市售刺猬饲料的饲料标签并不总是符合瑞士和欧洲法律。公众应该接受有关喂养E 的教育。 europaeus和野生动物商业饮食的风险。
