ABSTRACT
This study evaluated the effects of dietary supplementation with
brown macroalgae (Ascophyllum nodosum) at two inclusion levels (0.6% and
1.0%) on mineral digestibility, serum mineral concentrations, and femoral bone
characteristics in piglets. A total of 210 piglets were randomly assigned to
control (0%) or supplemented diets (0.6% or 1% macroalgae) from day 18 to
day 64. Supplementation at the 1.0% level significantly improved digestibility
and serum concentrations of essential minerals including calcium, phosphorus,
magnesium, copper, and iron. Meanwhile, the 0.6% supplementation led to
greater improvements in femoral bone mechanical properties, such as fracture
load, elastic work, and work to fracture, as well as in material properties, including
fracture and yield stress. These findings indicate that moderate supplementation
with A. nodosum (0.6%) is most effective in optimising bone mechanical
strength, and may represent a practical dietary strategy for improving skeletal
development in fast-growing piglets.
