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

It is intended to provide a method of determining a fatty acid composition contained in intramuscular fat based on the genotype of cattle, particularly a determination method for determining the size of oleic acid content simply and with high accuracy, and further provide a method of more objectively determining eating quality of beef based on the determination result. The invention provides a method of determining the size of fatty acid content in intramuscular fat of cattle based on the genotype of fatty acid synthase determined by an assay of the following base and/or , and a method of determining whether or not beef with excellent eatingquality can be obtained from the cattle based on the result. A base (either adenine (A) or guanine (G)) at the 16,024 position corresponding to a polymorphic site in a base sequence represented by SEQ ID NO: 1 in the sequence listing. A base (either thymine (T) or cytosine (C)) at the 16,039 position corresponding to a polymorphic site in the base sequence.
