Implication

A randomized trial examines dietary protein effects on steer growth and carcass merit, highlighting dietary efficiency implications.

Key Points

This research aims to evaluate the effects of varying crude protein levels in finishing diets on the growth performance and carcass quality of feedlot steers.
Utilized Angus × SimAngus-crossbred steers in a randomized complete block design.
Assigned 93 steers into two treatment groups with either 11.5% or 13.5% crude protein diets.
Measured interim body weights at 28-day intervals and collected blood samples for plasma urea nitrogen analysis at specified time points.
Steers fed the 11.5% crude protein diet had greater dry matter intake and tended to be heavier than those on the 13.5% diet.
No significant difference in average daily gain and gain to feed ratio between treatment groups.
Steers on the 11.5% diet exhibited lower plasma urea nitrogen concentrations at day 56 and had heavier hot carcass weights.
