NOVELTY - Balancing various factors for pigs, by selecting pigsty with proper ventilation and provision for sunlight, preparing pig feed, feeding sawdust feed to growing piglets, planting green trees or plants for balancing external environment of pigsty, maintaining proper temperature and humidity inside the pigsty, safeguarding pigsty from climatic influences and noise pollution, balancing suitable environmental conditions during breeding period by proper disposal of pig excreta and storage of pig feed, and preventing pollution caused by waste disposal.    USE - The method is useful for balancing various factors for pigs including external environment, internal environment, feed, waste disposal and pollution control (claimed).    ADVANTAGE - The method enables to reduce farming and feed cost, improve farming efficiency, drainage and pollution control, provide good working environment for breeding staffs, meet growth requirements of the pigs effectively, and balance nature, human development and pigs in harmonious and environmentally-friendly manner.    DETAILED DESCRIPTION - Method for balancing various factors for pigs, involves (a) selecting pigsty with proper ventilation and provision for sunlight far away from main road, railway over 1000 m, and densely populated area, where selected pigsty should not be surrounded by pollution causing industrial enterprises and other aquaculture field and can be accompanied by few local green infrastructures, (b) preparing pig feed comprising sawdust feed and normal concentrated feed, feeding 20 kg or more sawdust feed (0.5% of the total sawdust feed) to piglets, further feeding 10 kg sawdust feed to growing piglets, increasing feeding quantity by 5-50% and finally stopping the feeding process, (c) matting layer of padding material on cemented ground of relatively ventilated pigsty, where the layer from top to bottom comprises sawdust layer up to a thickness of 20 cm, rice hull layer up to a thickness of 15-20 cm and wood bran layer up to a thickness of 20 cm, and selecting fermentation tank having length of 100 cm, width of 90 cm and depth of 55 cm for fermenting the padding material, where the fermentation tank is designed for semi-open lid type fermentation by adding fermentation bacteria in the fermentation tank, (d) balancing external environment of the pigsty by planting green trees or plants including tall deciduous tree species, vegetable plant, flowering plant, grass, shrubs, insect repelling trees, trees/plants having antifouling, air purifying and malodorous substance absorbing ability and trees/plants that reduce impact of ozone, in rows surrounding and on both sides of the pigsty, making concrete urination ditches with movable cover seal, cleaning the pigsty on regular time intervals, and maintaining greenery rate up to more than 70% outside the pigsty, (e) balancing internal environment of the pigsty by maintaining proper temperature and humidity inside the pigsty with provision for natural or mechanical ventilation, taking required precautionary measures for adjusting and maintaining suitable temperature and humidity conditions inside the pigsty and creating good environmental condition for growth of the pigs, safeguarding the pigsty from climatic influences and noise pollution caused by various vehicles and processing equipments including water pump and feed processing device that are installed inside and outside the pigsty, providing provision for treatment of wastewater discharged from the pigsty that includes anaerobic fermentation, biological, physical and chemical treatment methods, creating safe and healthy habitat for the pigs, and reducing mood fluctuations in pigs that may result by environmental change, (f) balancing domestic habitat and environmental conditions during breeding period of the pigs by making provisions for proper disposal of pig excreta and storage of pig feed, and (g) maintaining proper balance between production of pig waste and disposal of the waste for preventing pollution by incineration or landfill method in accordance with livestock and poultry pollution prevention technical specification HJ/T81-2001. The sawdust feed is prepared by mixing 40-50 %mass sawdust, 15-20 %mass rice bran and 30-40 %mass forage uniformly to obtain mixture and sprinkling 1 kg yeast and 0.1 kg cloves on surface of 50 kg mixture, stirring the mixture uniformly, spraying water on the mixture, stirring the mixture uniformly, grasping the mixture with hand to ensure that water does not drop down from the mixture, and sealing and incubating the mixture until temperature of the mixture is increased to 50 degrees C or more, sawdust becomes soft, color of the mixture turns yellow, and the mixture starts releasing aroma of wine.
