牛的声音在英语中通常被称为"mooing". 例如，你可以说: "The cow's mooing was loud and clear." 这里是一个例子，你可以借鉴一下:
The cow stood in the field, mooing loudly. Its deep, lowing sound echoed across the farm. The farmer heard the cow and smiled, knowing it was time to milk her. He walked over to the cow and patted her on the back, saying, "Good morning, old girl. Let's get you milked and fed."
