Happy Thanksgiving everyone. Gotta calf off feed for the last 2 days. Switched him over from Purina Fitters Edge to a finisher Showrite Throttled Up. He ate it for 1 1/2 feedings (approx 33lbs total) then done. Won't touch a ounce of it. I pour in into his feed trough and he starts head butting it so I just pull it out. He's on the hay. Loose in his stools. I'm assuming he will get hungry enough and start eating eventually?
