Table 3. Boron concentrations in the serum, tibia, liver and breast muscle in broiler chickens fed diets with supplemental boron and phytase, individually or in combination.
| Diet1 | Control | Boron | Phytase | Boron + Phytase | SEM2 | P-value |
|---|---|---|---|---|---|---|
| Serum (mg/L) | 0.37b | 0.84a | 0.37b | 0.86a | 0.004 | 0.0001 |
| Tibia (µ g/g) | 0.18b | 0.36a | 0.17b | 0.33a | 0.019 | 0.0001 |
| Liver (µ g/g) | 0.21b | 0.36a | 0.17b | 0.36a | 0.004 | 0.0078 |

The broilers were fed a control diet that was formulated to meet the requirements for the strain (Ross 308) recommended by the breeder or a diet supplemented with preparations of boron (20 mg/kg), phytase (500 FTU g/kg phytase), or boron + phytase (20 mg/kg boron + 500 FTU g/kg phytase).
