I have 5 bred angus cows due to deliver between Sept-Jan. I was wondering if it's safe to apply pour on dewormer at this stage of pregnacy? Is there a particular time of the year when I SHOULDN'T deworm??? Thanks for the advice.

Grubs... shouldn't worm in the winter months, depending on your area. Not sure if that applies to Ivomec (ivermectin) or just Ivomec Plus.
Whether or not a pour-on wormer is OK for bred cows is entirely dependent on what type of wormer it is. Can you give us a brand name?
