less than

According to recent studies comparing the nutritional value of meat from wild
animals and meat from domesticated animals, wild animals have less total fat than
do livestock fed on grain and more of a kind of fat they think is good for cardiac
health.
do livestock 是什么意思啊?
还有 less than 和 more than 的平行结构是怎回事

那是倒装了，正常语序是  than livestock fed on grain do，为了避免头重脚轻，将 助词 do提前了。另外，这里由于没有歧义的存在，所以正确答案里把 do 省略了。

那个 do 代表的是have吗  是wild have less fat than livestock have吗？
