Study On The Technology Of Pig Fermentation Bed

The technology of pig fermentation bed is developing rapidly, more and more people pay attention to it. It has great significance both on the control emissions and pollution of pig. This topic is to be with pilot in chuan an ecological and agriculture limited company. Comparison With temperature in pig-house, ammonia concentration, meat quality, cost between fermentation bed technology and conventional cultivation. Then do the experiment of padding counters-field in the laboratory.In exp.1, it shows that temperature in pig-on-litter pig-house is higher than ordinary pig-house, which dose advantageous in winter but harms in summer for pig living.In exp.2, it shows that the technology of pig fermentation can reduce ammonia concentration greatly.In exp.3, it shows that the pig in pig-on-litter pig-house eat less feed, but heavier than pig in ordinary pig-house when grow up.In exp.4, it shows that meat quality of pig in pig-on-litter is better , which can meet the demand of green food.In exp.5, it shows that the technology of pig fermentation bed can reduce the cost, about 53 RMB every head.In exp.6, the padding after fermentation can be used as organic fertilizer, but it's fertility is limited.
