Betaine supplementation for finishing cattle

Crossbred heifers (756 lb) were used to

evaluate the effects of feed-grade betaine on

animal performance and carcass characteristics.

Heifers had ad libitum access to a finishing diet

without betaine or with 4, 8, or 12 g/day of

feed-grade betaine top-dressed at feeding.

Feed intakes, gains, and feed efficiencies were

not significantly altered by feed-grade betaine.

Hot carcass weights tended to increase with the

betaine supplementation, but dressing percent;

percentage of kidney, pelvic and heart fat; fat

thickness; or ribeye area were not altered.

Yield grades were numerically greater, and

marbling scores significantly greater for heifers

supplemented with 4 or 12 g/day of betaine.

These results demonstrate that supplementation

of feed-grade betaine may have minor effects on

performance and carcass characteristics.
