It was evaluated the effects of poultry litter treatment on moisture content, pH, density and volatilized ammonia for five consecutive flocks of broiler chicken breeding. It was used 640 birds per flock as a complete randomized design with eight treatments and four replicates. The treatments were the following: 1 non-treated litter; 2 litter submitted to in-house composting; 3 litter treated with aluminum sulfate; 4 litter submitted to gypsum; 5 litter treated with quicklime; 6 litter treated with dolomitic limestone; 7 litter treated with zeolite and 8 litter treated with charcoal. Chopped elephant-grass hay was used as poultry litter in all flocks. Fermentation in the shed increased moisture content of the litters in the second and first flocks on 21 and 42 days of breeding, respectively. There was no difference on density among treatments. Aluminum sulfate reduced pH of the litters in all flocks at 21 days of breding. On 42 days of breeding, pH of the litters was reduced in the litters with aluminum sulfate and gypsum in the first, second and forth flocks. On 21 days, aluminum sulfate reduced the volatilized ammonia in the first, third and forth flocks, and on 42 days, there was a reduction of volatilized ammonia in the litters with aluminum sulfate in the forth flock. Aluminum sulfate can improve quality of poultry litter of chopped elephant-grass hay by reducing pH and ammonia volatilization.

An experiment was conducted to assess the appearance, smell, texture, pH, temperature, chemical composition and energy content of ensiled Rice offal (RO) treated with non-protein nitrogen sources and soybean meal residue in a completely randomized design. Rice offal was treated with different proportions of Urea, Poultry litter (PL) and Soybean meal residue (SBMR) and ensiled. The treatment combinations were; A (100%RO), B (100%RO + Urea), C (75%RO + 25%PL), D (50%RO + 50%PL), E (75%RO + 25%SBMR) and F (50%RO + 50%SBMR). The treatments were ensiled for 21 days in triplicates. The results showed that silages were adequately fermented with sweet aroma. The silages were acidic (4.70 – 5.80) except for treatments C and D which had pH of 7.20 and 7.00, respectively. The temperatures of the silages were significantly (P<0.05) different. The proximate composition of silages differed significantly (P<0.05), being highest for %CP, %EE and ash in treatment B. Dry matter contents were also significantly different (P<0.05) with treatment A having the highest (90.25%). Rice offal and Urea mixtures resulted in silages with highest NDF, HEM and Energy. Lowest NDF was obtained in treatment without additive (Treatment A) compared to all other treatments. Least ADF was obtained in Treatment E (75% RO + 25% SBMR). Enhancement of rice offal with urea, poultry litter and soybean meal residue has shown improvement in the silage physiochemical quality
