- •
Apparent ileal digestibility of calcium in limestone was determined in broilers using the direct method.
- •
Calcium digestibility coefficients of the three limestone samples ranged from 0.54 to 0.61.
- •
Increasing the dietary phosphorus concentration from 0 to 4.5 g/kg increased the apparent ileal calcium digestibility of limestone from 0.56 to 0.60.
- •
Further studies are needed to determine the calcium digestibility of other commonly used calcium sources.
