The formulas to calculate space requirement for goats and sheep are:

1. For 35 kg Animal:

\[ SR = 0.80 \cdot Na \]

2. For 50 kg Animal:

\[ SR = 1.10 \cdot Na \]

3. For 70 kg Animal:

\[ SR = 1.40 \cdot Na \]

4. For Kid/Lamb:

\[ SR = 0.45 \cdot Na \]

5. For Buck/Ram:

\[ SR = 3.00 \cdot Na \]

Where:

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