My brother raises both grass and corn feed beef, his corn feed gets corn silage not grain corn.
The bunch that gets the corn silage is marbled a bit better and I believe has a better taste.
Because of our weather they all get fed all winter long;
haylage, and baled hay for the "grass fed herd",
haylage, corn silage and baled hay for the grain feed bunch.
Growth wise we don't see much difference in the groups,
marbling in the meat the grain feed have a bit more but with high quality pasture and haylage
the grass fed marble up decently.
Low quality pasture and having to travel to get water will slow down the growth rate and the quality
of the beef.
We weaned a bunch of almost yearlings last week, I watched the drive thru gates as we moved the calves
to a winter field/feed lot.
None of these are over 10 months old;
Just watching the gates that they don't try and get through while more get hauled in,
calf hauler with 8-9 calves in it, when I see him coming in I back out off the field road to let him in, as he pulls out I pull back in.
Not a real interesting afternoon but much easier than trying to get knot heads back in when they get out.
good fresh water, it's a bit cool but refreshing
