Another suggestion would be to start with less cattle and buy better quality. Many moons ago when I started the cattle business I purchased my first registered cows from a sale hosted by 5 or 6 registered breeders. I didn't do enough homework on the breeders that I bought from and also listened too closely to the sale manager of the sale (wasn't thinking at the time that he is working for the seller, not the buyer). Though I thought I knew the kind of cattle I wanted I wasn't detailed enough in my thinking and came home with cattle that in hindsight I probably wouldn't have purchased if I was more disciplined in my selection crieteria.
So, learn from my mistakes.
-Have a firm idea in your mind of the type of cattle you want (frame score, fleshing ability, appearance, performance records, EPDs, etc.) and don't waiver from it. If you don't have a firm idea of what you want, take some time visiting seedstock herds to learn their philosophies and determine if their thoughts make sense to you. Talking to others should help you solidify in your mind the type of cattle you want to raise.
-Don't be fooled by fancy ads in breed magazines...that doesn't mean their cattle are necessarily good...many aren't.
-Don't be fooled by fancy, white painted fences and the fact that they have been in business 50 years. I know a so-called seedstock operation that has raised registered cattle for over 50 years. They are very proud of that fact and because of it think they know the cattle business and what are good cattle. I find it interesting that this "seedstock" operation with over 150 cows, in cow country, struggles to sell 10 bulls a year. Truthfully, they don't sell many bulls because their cattle don't work for commercial producers; they are just blind to the fact.
-Don't think that if you buy "pretty good" cows you will be able to improve the herd fairly quickly by using the top bulls in the breed with AI. Trust me, I've tried this and it is amazing how many years it has taken for me to get to where I am with my cows...and I'm still not satisfied. Buy quality at the start!
Good luck and have fun in your adventure!
