The formulas to calculate lairage space requirement are:

1. For Large/Loose Type:

\[ SR = 2.23 \cdot Na \]

2. For Large/Tie-Up Type:

\[ SR = 3.30 \cdot Na \]

3. For Swine Less Than 100kg:

\[ SR = 0.70 \cdot Na \]

4. For Swine More Than 100kg:

\[ SR = 0.60 \cdot Na \]

5. For Small Animals:

\[ SR = 0.56 \cdot Na \]

Where:

• \(SR\) is the space requirement in square meters.
• \(Na\) is the number of animals.
