Resumo
The effects of
dietary electrolyte balance (DEB) on the femurs and litter of broilers were evaluated. Nine hundred and sixty
birds from 7 to 21 days of age and eight hundred and sixteen birds from 22 to 38 days of age were used in the
first and second experiments, respectively, distributed in a completely randomized design with four treatments
(DEB: 200, 240, 280 and 320mEq/kg) and four replicates. Poultry litter was analyzed for moisture, pH, volatilized
ammonia and bulk. Femurs were weighed and analyzed for bone density, morphometry and weight/length index.
DEB did not affect (P>0.05) the bones at 21 and 38 days or the pH, volatilized ammonia or bulk of litters at 21
days, but there was a linear effect (P<0.02) of DEB on moisture (Ŷ = 24.10 + 2.19X, R2=0.37). There was no
effect (P>0.05) of the treatments on the pH or volatilized ammonia of litters at 38 days of age. However, the
moisture (Ŷ =35.01 + 3.30X, R2=0.29) and bulk (Ŷ =194.17 + 31.12X, R2=0.54) of the litters increased (P<0.03)
when the DEB value was higher than 280mEq/kg. It was concluded that diets with 200mEq/kg of DEB can be
used for broilers with no negative effects on bone and poultry litter parameters.
