A quality enhancement green strategy for broiler meat by application of turmeric (Curcuma longa) powder as litter amendment to affect microbes, ammonia emission, pH and moisture

摘要

In multi-cultural Sri Lankan conditions, poultry meat is paramount importance in ensuring food security and improving nutrition. Issues as contact dermatitis and ammonia emission in broiler industry which caused by diminished litter parameters cause reduction of meat quality, profits and environmental conditions. Therefore use of Turmeric (Curcuma longa) (TM) powder as an antiseptic litter amendment at several application levels to enhance litter parameters with microbial demolition was attempted. Three months old broiler litter (2 kg) sample was taken and initial pH and moisture was determined. Turmeric was used to mix at levels of 0%, 1%, 3%, 5% and 8% (w/w). After mixing, 150 g of mixed litter was placed in container for each level of the 4 replicates, incubated for 5h and analyzed for Total Plate Count (TPC), Yeast and Mold Count (YMC), total Nematode Count (NC), ammonia emission, pH and moisture. Significant reduction (p <0.05) of total bacteria was seen (20%, 46%, 95% and 96%) when 1%, 3%, 5% and 8% applications of TM. The YMC reduction was also significant (p <0.05) (34%, 41%, 55% and 65%). Total nematode reduction (p <0.05) was 22%, 45%, 62.5% and 70%. A significant (p <0.05) pH reduction with increment of TM also seen (0.1, 2, 3 and 3%). Moisture (%) was increased (p <0.05) (6, 0.78, 19 and 1%). Ammonia emission was significantly decreased (p <0.05) by increased TM (64, 68, 73 and 84%) against control. It was concluded that the bacterial, fungal, nematode counts, pH and Ammonia emission of broiler litter can be significantly reduced with the application of 8% (w/w) of turmeric powder.
