Аннотация
OBJECTIVE: 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.
MATERIAL AND METHODS: 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.
RESULTS: 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.
CONCLUSION: Labelling and content of all-meat-products should be thoroughly checked to identify products with high liver percentages.
CLINICAL RELEVANCE: An excessive vitamin A intake can occur when feeding with horse-meat products with a high liver content over a long period.
