If the feed ration stays the same, they'll continue to gain but not as fast. We've always moved the steers to pasture in the spring with self feeders. We realize its takes slightly longer but we feel its a better, healthier end product. The cattle are free to roam (keep in mind it isnt a huge pasture, 45 acres of low land for 25 steers)and eat what they want rather then stuck shoulder to shoulder with other steers, ankle to knee deep in sh#t forced to eat whats infront of them. We find that the people buying freezer beef are happier as well when they know or can see the enviroment thier beef is raised in.
