It seems to me that running a feedlot is easier to calculate income & expenses. Animals come in and they all go out. With a cow/calf operation, you may only sell 1/2 your calf crop some years, so those replacements have to be calculated into the profit. It's just not as "cut & dry".
Do you calculate depreciation into the figures??
If I take Advertising, Breeding/Registrations, Feed/Hay, Fertilizer, Land Rent, Sale Expenses, Show Expenses, Vet/Vet supplies as expenses.
And, Cattle Sales & Show Income, I come up with $141/head of mature cows. But, I ended up keeping 14 replacements.
Now, that doesn't take in any tractor expenses, supplies, depreciation and other farm tax deductions, value of replacement heifers retained.
So what are you guys using as income/expenses?
