Method of determining size of fatty acid content in intramuscular fat of cattle based on genotype of fatty acid synthase and method of determining eating quality of beef based on the result

摘要

The present invention has an object to provide a method of determining fatty acid composition in intramuscular fat on the basis of bovine genotype, in particular a method of simply determining an amount of an oleic acid content with a high degree of accuracy, and a method of objectively determining the goodness of eating quality of beef on the basis of the results of the determination. The present invention provides a method of determining an amount of fatty acid content in bovine intramuscular fat on the basis of the genotype of fatty acid synthase determined by determining base 1 and/or base 2 described below, and a method of determining whether cattles are those from which beef with an excellent eating quality is obtained on the basis of the results thereof. 1 A 16,024th base corresponding to a polymorphic site which is either adenine (A) or guanine (G) in a base sequence represented by SEQ ID NO. 1 of a sequence list. 2 A 16,039th base corresponding to a polymorphic site which is either thymine (T) or cytosine (C) in the same base sequence.
