Not tb but I have fed a 7/8th TB the same and he also looked very good. Turnout + ad lib late cut haylage when in with two feeds of unmollassed chaff + micronised linseed + unmollassed sugar beet + a balancer. I up the linseed as the quality of the grass dimishes but tbh ours isn't bad ATM.He is beautiful. I think he has very good condition in winter for a TB as well! What do you feed him?
