A Detailed Explanation of the Formation Patterns of Beef Marbling

The formation pattern of beef marbling is as follows: before 12 months of age there is very little marbling, between 12 and 24 months of age the marbling increases rapidly, and after 30 months of age the marbling changes very little. From this it follows that to obtain high-grade beef with good economic returns, cattle should be slaughtered at 18 to 24 months of age. At present, the slaughter age of beef cattle abroad is generally 1 to 1.5 years, and no later than 2 years at the latest.
