Use of poultry litter as manure  The fully built-up deep litter removed from the poultry farm is added to fish pond as manure.  The poultry droppings from the poultry farms is collected, stored it in suitable places and is applied in the ponds at regular instalments.  Applied to the pond at the rate of 50 Kg/ha/ day every morning after sunrise.  Direct recycling and excess manure however, cause decomposition and depletion of oxygen leading to fish mortality. It has been estimated that one ton of deep litter fertilizer is produced by 30-40 birds in a year.  As such 500 birds with 450 kg as total live weight may produce wet manure of about 25 Kg/day, which is adequate for a hectare of water area under polyculture.  The fully built-up deep litter contains 3% nitrogen, 2% phosphate and 2% potash. Poultry husbandry practices:  For the first 14 days, chicks need to be raised separately in a brooder (not on pond), as they need higher temperature of 28-33°C (85-95°F). Each chick during this period needs a space of 7.5 x 7.5 cm (9 in2). To maintain the required temperature range, surround the chicks in a bamboo fence and hang an electric or kerosene lamp above them. A rice husk heater can also be used. Broilers:  30-50 broilers could be raised on a 1000 m2 pond.  The chicken house can be constructed over the pond at least 0.5 m above maximum pond water level, or on the embankment.  Each bird requires 1.5 ft2 space (50 birds require 75 ft2 space).  Broilers reach market size of 1.5-1.8 kg in 7-8 weeks and it is possible to raise six batches in a year.  Any fast-growing chicken, like Shavar Starbro broilers, can be raised.
