Nitrogenous and Glicydic Fractions and Ammonia Released by Broiler Litter in Different Stocking Densities and Periods of Breeding

[摘要] - The objective of this work was to study the ammonia released, levels of moisture, glicydic compounds (reducing sugars) and nitrogenous fractions (N-total, N-soluble, N-nitrate) of broiler litter submitted to different stocking densities (10; 14; 18 and 22 broiler per m2), both sex, and three breeding periods (24, 38 and 42 days). The experiment was carried out in a random design and analysed as a 4x2x3 factorial. In general the sex did not affect the studied variables. The amounts of released ammonia, moisture, N-total, and N-soluble enhanced with the increase of density and confining time of the broiler, but the levels of reducing sugar decreased. These results show the need of ammonia monitoring and control, mainly at high densities and at the end of breeding period.
