Effect of Partial or Complete Replacement of Dietary Inorganic Trace Minerals Supplement with an Advanced Chelated Source on Nutrient Digestibility in Sheep
The delicate balance of trace mineral supplementation is critical for optimizing rumen function and overall ruminant health. This study evaluated the solubility of an advanced chelate technology-based supplement and assessed its impact on rumen degradability and apparent total tract digestibility (ATTD) when replacing inorganic sources. The solubility of the advanced trace minerals supplement (ACTM) was assessed at pH 5 and pH 2. In situ ruminal degradability of dry matter (DM), organic matter (OM), and fiber fractions was evaluated using two fistulated rams fed diets supplemented with either ACTM or inorganic trace minerals. ATTD was determined in 6 lambs fed diets supplemented with 100% ACTM, 50% ACTM, and 50% inorganic (50% ACTM), or 100% inorganic sources in a Latin square design. Results showed solubilities ranging from 6.75% to 11.81% at pH 5, increasing to 69.24% to 80.47% at pH 2. ACTM supplementation significantly enhanced the rumen degradability of neutral detergent fiber (NDF) and acid detergent fiber (ADF) at 6 h of incubation (p ≤ 0.05). The 100% ACTM treatment significantly decreased rumen pH (p = 0.051) and improved DM, OM, NDF, and ADF digestibility, as well as trace mineral absorbability compared to 100% inorganic (p ≤ 0.05). These findings highlight the potential of ACTM supplementation to enhance ruminal degradability, promote better trace mineral absorption, and improve the ATTD of nutrients compared to inorganic sources.
