# Additional Details

## <mark style="color:yellow;">Additional Details on the 100% Confined Cattle System</mark>

**The 100% confined cattle system involves some essential details in its operation:**

### <mark style="color:yellow;">Age of the Animals:</mark>

**Typically, animals are confined starting from 18 months of age.**

### <mark style="color:yellow;">Confinement Duration:</mark>

**The duration of confinement varies according to the desired slaughter weight. On average, animals remain confined for a period of 90 to 120 days.**

### <mark style="color:yellow;">Production Cost:</mark>

### Compared to the pasture production system, confined cattle tend to have a higher production cost. However, this additional cost can be offset by the increase in productivity and the superior quality of the meat.

### <mark style="color:yellow;">In recent years, the 100% confined cattle system has experienced significant growth in Brazil. In 2023, it is estimated that approximately 15% of beef production in the country comes from animals raised through this method.</mark>
