Finishing strategies for steers based on pasture or silage plus grain and time on feed and their effects on beef quality

The aims of the present study were to compare the quality of grain-fed and pasture-fed beef and to assess the effects of two feeding periods on grain for finishing steers. A group of 75 steers were fed one of 5 finishing diets (n = 15 per diet): pasture for 90 d (P), oat grain plus pasture silage fo...

A group of 75 steers were fed one of 5 finishing diets (n = 15 per diet): pasture for 90 d (P), oat grain plus pasture silage for 35 d (SO), oat grain plus pasture silage for 75 d (LO), wheat grain plus pasture silage for 35 d (SW), and wheat grain plus pasture silage for 75 d (LW).

The beef from steers fed wheat plus silage for 75 d had lower tenderness scores than beef from steers fed for 35 d on grain plus silage.
