Abstract

Laying aside manure meat, milk and egg is considered as key performance indicator of livestock farm profitability of Bangladesh till yet whereas manure contains minimum 45-55% feed nutrient fed to animals. A survey based research work was conveyed to find out the major channel of using this valuable livestock manure by farmers from twelve selected district of Bangladesh. Results showed that most of the cattle and buffalo farmers prefer solid storage system to manage their manure. From this stored manure, about 35% was used for land fertilization, 47% for burning fuel preparation, 8% for composting and remaining 10% become completely wasted. A very few of cattle manure (4.65) was utilized by the care of anaerobic digestion. But this improved system was completely absent in case of buffalo and small ruminants manure management. Dung produced from small ruminants fully goes for solid piling. About 20% of poultry manure managed in improved way and the remaining portion was mostly utilized in a very disparage way. In anaerobic digestion system, the produced gas went for home consumption and bio-slurry creates havoc for both farmer and environment. Land fertilization and aquaculture coves its utilization but the amount is too low compared to its production. Above 52% of total bio-slurry become wasted due to limited knowledge and lack of appropriate handling techniques. The scenario of urine and liquid slurry management was very melancholic. About 0.37 and 0.203 kg methane emission per head per year was calculated from solid storage system of cattle and small ruminant animal manure. The value is also high in burning fuel preparation (5.46 kg) and liquid slurry (5.81 kg) and a bit low in anaerobic digestion system (1.24 kg) per head per year.
