Feedlot Trials Confirm ZinMet Improves Carcase Performance on Finishing Beef Cattle
Profitability in feedlot operations depends on one core principle: converting feed into weight as efficiently as possible.
Extensive feedlot trials confirm that ZinMet, an organic trace mineral additive, delivers measurable improvements to cattle performance, feed efficiency and carcase outcomes - without increasing feed intake.
Between 2002 - 2009, five independent feedlot trials were conducted by Global Animal Products across 51 replicates with a total of 1,329 beef cattle. In each trial, ZinMet replaced Zinc at the recommended feeding level to assess its impact on finishing cattle performance. ZinMet’s unique combination of Zinc, Chromium and Methionine was proven to bypass rumen degradation at an enhanced rate of 80%, making it more readily available through the gastrointestinal tract.
Cattle supplemented with ZinMet gained an additional 7.5 kgs of liveweight over a 150 day feeding period, compared to the unsupplemented cattle. The cattle fed with ZinMet used the nutrients in their rations more efficiently, converting the same amount of feed intake into a greater weight gain. These results were consistent and commercially valuable.
The Average Daily Weight Gain (ADG) increased from 1.61 kgs/day to 1.71 kgs/day with ZinMet – an increase of 3%. Feed conversion efficiency also improved by 2.3%, further reinforcing ZinMet’s role in boosting nutrient utilisation.
ZinMet cattle recorded an average increase of 3 kgs in hot carcase weight (HCW) over the 150 day feeding period. As the days on feed and total feed intake remained constant, the inclusion of ZinMet was the primary contributor to the increase in both the liveweight and HCW.
The biological advantage of ZinMet lies in its organic form. Unlike inorganic zinc sources, ZinMet is more bioavailable, meaning cattle absorb and utilise the minerals more effectively. Zinc plays a critical role in enzyme function, immune response and protein synthesis - all essential processes for growth and performance in high-energy feedlot diets. By optimising zinc availability, ZinMet supports metabolic efficiency, allowing cattle to do more with the nutrients they consume.
Across multiple trials, locations and years, ZinMet consistently delivered better feed efficiency and increased weight gains. For feedlot operations, these outcomes effectively contribute to heavier cattle, lower operational costs and stronger financial returns.
In an environment where margins are tight and efficiency matters more than ever, ZinMet is an evidence-based, practical solution to enhance feedlot performance and unlock additional value from every kilogram of feed.
