Using a seasonal pasture rental fee of $30 per acre, the total pasture cost would come to $216 per year. In calculating the winter feed costs, Hoppe figured a 1400-pound cow will either eat or waste 40 pounds of feed daily.Using a hay price of $65 per ton and figuring 180 days on feed with the winter ration that translates into a feed charge of $1.40 per day or $252 for six months.et income over life of cow = $2582.03. If a producer would like to realize a profit of $200 per head each year that would be an additional cost of $940 over the life of the cow, meaning that the value to pay for a bred heifer would be $1642.03.
