The formulas to calculate space requirement for goats and sheep (slatted floor) are:

1. For 35 kg Animal:

\[ SR = 0.70 \cdot Na \]

2. For 50 kg Animal:

\[ SR = 0.90 \cdot Na \]

3. For 70 kg Animal:

\[ SR = 1.10 \cdot Na \]

4. For Kid/Lamb:

\[ SR = 0.35 \cdot Na \]

5. For Buck/Ram:

\[ SR = 2.60 \cdot Na \]

Where:

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