Abstract

Application of water-saving self-feeders can reduce water consumption of pigs by more than 50% . so the feeding-watering system one of the most important way of the reduction of the slurry. Bioactive deep litter housing can eliminate slurry. Matured urine, faeces and litter can use for the purposes of soil conditioning and fertilizing . Water-saving slurry handling technology can halve manure dilution so it can double the nutrient content of the slurry. By using of straw bale biofilter for reducing emissions of pig houses makes fattening of pigs possible close to populated area. Developed rate control system for slurry application make avoiding over-fertilization possible , can fulfill better the demand of nutrient of plants. By means of computer aided manure utilization system area distribution of soil characteristics can determinate . The system is suitable for planning the utilization of manure and slurry in environment -friendly way.
