In VOA special English level 2 there is sentence:

He added that having a computer identify which of his 2,000 cattle need attention could help improve farm productivity by up to 10 percent. He estimates this difference could greatly increase his profits.

“Just a 10 percent or five percent increase, or improvement in productivity, means hundreds of thousands of dollars to us, aside from the fact that we just want happier and healthier and more welfare in our animals, anyway.”

Who is happier and healthier and more welfare in the below sentence?Are the people healtier.... or the animals healtier...?
