Implication

Evaluates the impact of different feed additives on growth performance and feed efficiency in beef cattle, indicating potential benefits for finishing diets.

Key Points

The aim was to evaluate how different feed additives affect intake, growth performance, and carcass characteristics in finishing beef cattle.
Randomized complete block design with 56 steers
Four treatments tested: Control (no additive), Monensin, CattIActive, Monensin + CattIActive
Feeding duration of 168 days with 24 days adaptation to a high-concentrate diet
Statistical analysis using the MIXED procedure of SAS.
No significant effect on final body weight or carcass characteristics among treatments
CattIActive showed improved weight gain during the adaptation period compared to Monensin
Feed efficiency was better with Monensin + CattIActive during the initial feeding phase, but not overall.
