METHOD OF DETERMINING AN AMOUNT OF FATTY ACID CONTENTS IN BOVINE INTRAMUSCULAR FAT ON THE BASIS OF GENOTYPE OF FATTY ACID SYNTHASE GENE AND METHOD OF DETERMINIG GOODNESS OF EATINGQUALITY OF BEEF ON THE BASIS OF THE RESULTS THEREOF

摘要

It is intended to provide a method of determining a fatty acid compositio n contained in intramuscular fat based on the genotype of cattle, particular ly a determination method for determining the size of oleic acid content sim ply and with high accuracy, and further provide a method of more objectively determining eating quality of beef based on the determination result. The i nvention provides a method of determining the size of fatty acid content in intramuscular fat of cattle based on the genotype of fatty acid synthase det ermined by an assay of the following base and/or , and a method of determini ng 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 t he 16,024 position corresponding to a polymorphic site in a base sequence re presented 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 sit e in the base sequence.
