Improved breeds are like delicate hothouse flowers, protected under a myriad of safeguards, that produce beautiful blossoms. Native breeds are like wildflowers in the field. They may not be much to look at, but they can survive the wind and the frost.
改良種就像溫室裡的花朵，在萬般保護下，開著最美麗的花朵，土種動物則像野地裡的小野花，雖不起眼，卻能在寒風霜雪中，存活下來。
