What is the primary reason the Pygmy buck is paired with the Nubian doe, rather than the reverse cross?

Answer

The Nubian doe is significantly larger, ensuring safe gestation.

The size asymmetry is necessary for a safe gestation period; attempting the reverse cross with a smaller Pygmy doe carrying larger offspring is strongly discouraged due to risks.
