Which is more profitable buying weaned steers/bull calves , or cow calf operation? Cow eats about 4 tons of hay a year. And the time to get your money back takes a while. Plus you have to feed a bull. I feed hay, I have 6 acres of quality alfalfa. I figure you can buy a steer for about $300 and sell in 5 months for $800 Ish. Or buy an old cow for $600 let it raise the calf for 2 months sell the mom, keep Calf for 4-5 more months then sell calf. Any experience? Thanks. Slaughter weight is .50 cwt in my area.
