Abstract: Large-scale piggery structure was designed in full contactable microbial fermentation bed for breeding sows, of which, the land for entire piggery was 5 700m2 including workplace and green belts along sides.The piggery for breeding sows was 93 mlong and 33 mwide with total area 3 069m2, including office area 60m2, aisle107m2.The microbial fermentation bed covered area 2 902m2 with 88.7mlong and 27.7mwide, it occupied 95%of the total area of the piggery.The thick of padding on microbial fermentation bed was 80 cm in height with volume2 321m3, packed with 733 tons of coconut chaff+rice chaff.The large space of microbial fermentation bed would be separated in different functional zones for boar breeding, gilts, pregnant sows, sow delivery table, as well as piglets nurse culture.The piggery would also be equipped with automatic control systems such as automatic feeding, automatic sprinkler, automatic orientation corral for pregnant sows, sow delivery table system, fan-water curtain cooling system, video monitoring system, environmental parameter system including light, temperature, water, humidity, CO2, NH3 and so on.The feeding trough and water trough were placed in each zone and the overflow pipe was designed for water trough to remove extra water.The piggery was designed in capacity for breeding 500 sows and 4.9m2 microbial fermentation bed enjoyed by each sow in average, with annual output of 10 000 piglets.
