Background: It's been a tough summer here in Arkieland. I weaned some calves off some heifers that have had a hard summer. Neither the calf nor the heifers looked good. I have the calves up and have been feeding about 5lb/day 14% feed along w/ free choice hay. I'm trying to get them to slick up a little. Assuming a calf eats 3% of its body weight per day, a 300 lb calf will eat 9 pounds per day. If I'm feeding about 5 lb/day 14% feed, is he eating 4lb hay? What is the minimum hay they need in their system? Thanks
