Horse meat is often used in the context of an elimination diet. For reasons of practicability some pet owners feed canned horse meat, which is commercially available. Based on a report of a cat with food allergy that displayed cervical spondylosis, the vitamin A content was analyzed in various horse meat products.
The vitamin A (retinol) content was analyzed in 14 commercially available horse meat products. The content of metabolizable energy was calculated on the basis of the declaration by using estimation equations.
High amounts of vitamin A were found in some products for which liver, offal or animal by-products were labelled as contents. When feeding exclusively with one of these products, the vitamin A supply was just below the safe upper limit for cats while above the safe upper limit for dogs.
Labelling and content of all-meat-products should be thoroughly checked to identify products with high liver percentages.
An excessive vitamin A intake can occur when feeding with horse-meat products with a high liver content over a long period.
马肉常用于排除饮食的背景中。出于实用性考虑，一些宠物主人会喂食市售的罐装马肉。基于一只患有食物过敏且伴有颈椎病的猫的报告，对各种马肉产品中的维生素A含量进行了分析。
对14种市售马肉产品中的维生素A（视黄醇）含量进行了分析。可代谢能量的含量根据产品标注，使用估算方程进行计算。
在一些将肝脏、内脏或动物副产品列为成分的产品中发现了大量的维生素A。仅用其中一种产品喂养时，猫的维生素A供应量略低于安全上限，而狗的则高于安全上限。
应仔细检查所有肉类产品的标签和成分，以识别肝脏比例高的产品。
长期喂食肝脏含量高的马肉产品可能会导致维生素A摄入过量。
