Abstract

Beef cattle routinely undergo a variety of stressors within the preconditioning and feedlot receiving phases which may impair animal performance and health. Trace mineral supplementation, either through dietary or injectable sources, is proposed to mitigate these effects through metabolic and immune system support. Two systematic reviews and meta-analyses were conducted to evaluate the efficacy of two different oral supplementation methods, organic (OTM) and inorganic (INR), and injectable trace mineral (ITM) solutions on average daily gain (ADG) and morbidity. Across 20 studies, OTM supplementation increased ADG (P = 0.01) when compared to INR, but did not affect morbidity (P = 0.92). In a separate analysis of 16 studies, ITM administration did not influence ADG (P = 0.21) or morbidity (P = 0.20). Collectively, these findings suggest that while morbidity outcomes remain unchanged, targeted trace mineral supplementation strategies through OTM sources can support animal performance during periods of increased stress.
