Final answer:
Steers have the highest cutability among the sex classes of beef due to their higher muscle mass and lower fat content, resulting in more usable meat and an economically favorable yield.
Step-by-step explanation:
The sex class of beef with the highest cutability is typically the steers.
Steers, which are castrated male cattle, generally have less fat and more muscle compared to heifers (female cattle), bulls (intact male cattle), and cows (mature female cattle). This results in a higher yield of usable meat and thus a higher cutability score. Cutability refers to the proportion of meat that can be harvested from an animal carcass and is an important factor when assessing the economic value of different sex classes of beef cattle.
While the diet and conditions of raising cattle, such as grass-fed or grain-fed methods, can influence the overall quality and market price of beef, steers are traditionally preferred for their efficient growth and meat yield.
