If you want to get into cattle, just remember that it takes the same amount of feed/hay to keep a poor cow as it does a good cow. But the good cow well raise a better calf and a better calf we'll bring more money.
You don't need to get attached to them like a pet, at the end of the day their are food animals and you never now when you'll have to put one down.
You can make some money at it but if you start buying all brand new equipment, it'll take a long time to show a profit.
You should look into it what breads or color cows/calfs bring more money in your area, you can have the best cows in the world but if no one wants them, there not worth anything.
also farm credit has a young farmers program to help young farmers buy land, I think you need to be under 40 and have %15 money down and the land/farm need to cash flow itself (be able to pay for itself)
If you wanted livestock and can't afford cows, you could go with meat goats or hair sheep (their meat sheep on wool) but you need to know if their is a market for them where you live at.
On the other hand, I dont wheel as much as i use to. Work a 40 hour off farm job and farm a couple hundred acres too. It can take a lot of you time but if you enjoy it, go for it. You can always Sale out if it don't work
