The formulas to calculate space requirement for cattle shed or barn are:

1. For Calves Up to 3 Mo:

\[ SR = 1.00 \cdot Na \]

2. For Calves 2-3 Mo:

\[ SR = 2.00 \cdot Na \]

3. For Calves 7 Mo-1 Yr:

\[ SR = 3.00 \cdot Na \]

4. For Yearling 1-2 Yr:

\[ SR = 4.00 \cdot Na \]

5. For Heifer/Steer 2-3 Yr:

\[ SR = 5.00 \cdot Na \]

6. For Milking and Dry Cow:

\[ SR = 6.00 \cdot Na \]

7. For Cows in Maternity Stall:

\[ SR = 10.00 \cdot Na \]

Where:

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