|Study it was attempted to compare the microbial dynamics and Ammonia emissions of turmeric powder (TM)applied broiler and layer litters in several applications, as an amendment. Three months old broiler and layer (2kg each) litter sampleswere analyzed. Initial pH and moisture was determined. Turmeric powder was used to mix with both litters at 5 levels; 0%, 1%, 3%, 5% and 8% (w/w). After mixing, 150g of samples was placed in a container for each level of the 4 replicated samples, incubated 5h and analyzed for Total Plate Count (TPC), Yeast and Mold Count (YMC), total Nematode Count (NC), pH, moisture and ammonia emission.
Microbial parameters showed a significant reduction (p<0.05) for increment of TM. The reduction TPCs of layer litter were 42.42%, 60.6%, 95.15% and 98.18%, when 1%, 3%, 5% and 8% applications of TM. Reduction of YMC was observed >99% when treated with TM compared with >108 count of 0%. The NC reduction was 21.87%, 34.37%, 50% and 53.12%. For Broiler litter the reduction of TPC were 20.34%, 46.06%, 95.73% and 96.08%. The YMC reduction against control was 34%, 41.72%, 55% and 65.34%. The NC reduction was22%, 45.81%, 62.5% and 70.87%.
The pH of layer litter was significantly (p<0.05) reduced with increment of TMfrom 0.91, 2.19, 2.3 and 2.83%. Broiler litter also showed significant reduction of pH from 0.1, 2.75, 3.64 and 3.42%.Moisture % of layer litters were significantly (p<0.05) increased at 1, 5 and 8% levels from 1.38, 0.12, 3.28% and significantly decreased at 3% from 1.32% and in broiler litters the moisture % were significantly (p<0.05) increased along TM levels from 6.23, 0.78, 19.33 and 1.17%. Ammonia emission was significantly decreased (p<0.05) by increasedTM for both layer (45.58, 50.35, 68.02 and 70.61%) and broiler litters (64.09, 68.31, 73.32 and 84.67%).It was concluded that the TPC, YMC, NC, pH and Ammonia emission of poultry litter (both layer and broiler) can be significantly reduced by application of 8% (w/w) of turmeric. It was more effective in reduction of TPC, YMC and NC in layer litter and pH and NH3 in Broiler litter.
