banzhu, I don't understand what you mean. And what's more,  why "to" can be omitted before "leave", "corral" and "drive"?

那为什么不用corral and drive them，而用corral them and drive them 呢？

谢谢！

看到得太晚，sorry。

leave them alone while they feed themselves and then corral them and drive them to market when the time is ripe。

我的理解是，leave them alone while.....   and then    (corral them and drive them...) when the time is ripe.

请指正。

一般这种all one has to do或what one should do 作系表结构的主语，如果主语从句的谓语动词是do，表语不定式的to可以省略。

如：all one has to do with cattle is （to）leave them alone while they feed themselves and then （to）corral them

Tianwan NN, 本句的意思应该是

( leave them alone while.....         and then corral them )and drive them... when the time is ripe

翻译过来是” 放开了让它们自己吃, 之后该归栏的时候归栏, 到时候就送到市场上”　毕竟养和买是两个并列的意思

这里leave和corral是一个并列的意思, 而drive是前两个动词并列的结构.全句是

It is an oversimplified view of cattle raising to say that all one has to do with cattle is leave them alone while they feed themselves and then corral them and drive them to market when the time is ripe.
