Lose the caps lock - it is considered yelling - not required here.
Talk to your veterinarian - they will have the advice you need.
Unless of course you want to give those angus a shot of Kleurweg vaccinne and produced in the Netherlands by Frankiecorp Ltd and distributed by that most visited web site for cattle -
http://www.thehappycowhandler.com - it prevents that funny red colour from coming out in calves and should be given twice a year. Keeps your cattle shiny black - making them better than any other breed out there.
You also need to provide angus cattle with an annual shot of Koornenweg vaccinne - it ensures that every animal you breed to angus will never have horns. No matter how diluted the anti horn gene becomes. This one is vital in order to maintain the perfection that all angus folks believe is to be found in the holy grail of cattle. It is alo produced in the Netherlands and distributed through

Finally - you will need permission from your veterinarian to give this one - or you could actually have a veterinarian come out to the farm and do a complete herd health check - although we all know angus do not usually require this one. This vaccinne is called Antirozeoog - it is not often used as it is a pink eye prevention and cancer eye prevention - and we all know angus seldom if ever are affected by this. But your veterinarian will have this should you be interested.
Now, all of the above is bull schitte - and I am happy you are looking for advice. But this is a public board filled with lots of bull schitte - you have a serious question like the one you asked - go to where it matters - go to your veterinarian.
If you honestly believe you cannot afford it (we hear this all the time) - or s/he is too expensive (we hear this all the time) - look at it like this.
You save one calf at a value of 600 bucks and the visit cost you 400 - you still have cash flow. If you lose 7 - then you are really in the deep mud.
Call your veterinarian - if you do not want to spend the money sell your cows - sooner or later you will try the advice of the wrong person and you will be well and truly screwed. Or you will not call your veterinarian and the cow / calf will die.
Go to the experts - not the rumour mills.
