The law of the formation of beef marbling

The rule of beef marbling formation is that there are few patterns before 12 months old, but increase rapidly between 12 and 24 months old, and change little after 30 months old. As a result, in order to obtain high-grade beef with high economic benefits, it is necessary to go out at the age of 18 to 24 months. At present, the slaughtering age of beef cattle abroad is generally 1 to 1.5 years old. No more than 2 years old at the latest.
