Abstract
The environmentally friendly pig raising fermenting bed padding of one kind is prepared using fermenting agent and fermentation substrate as raw material by heap fermentation；Fermentation substrate includes following parts by weight material: 15-35 parts of cotton stalk, 10-40 parts of vinegar grain, 10-40 parts of peanut shell, 10-20 parts of Pleurotus eryngii mushroom bran；The parts by weight of fermenting agent are 1-5 part, living bacteria count >=10 in fermenting agent8Cfu/g, efficient bacterium group therein are combined into bacillus+saccharomycete+lactic acid bacteria+actinomyces, and meet following living bacteria count ratio: bacillus: saccharomycete: lactic acid bacteria: actinomyces=1-5:0.5-1.5:1-3:1-3.The feeding environment that live pig can be effectively improved using fermenting bed padding obtained after fermentation substrate of the invention and fermenting agent progress heap fermentation, is reduced pig house peculiar smell, improves the productivity effect of live pig.
Description
Technical field
The invention belongs to technical field of animal husbandry, and in particular, to a kind of environmentally friendly pig raising fermentation mattress
Material and preparation method thereof.
Background technique
Pig raising is the important component of China's agricultural production, is the important means that increasing peasant income are got rich, pork annual output
50000000 t or so, rank first in the world.It is counted according to the Ministry of Agriculture, in October, 2011, whole nation live pig livestock on hand was up to 4.71 hundred million.However,
While pig breeding industry is grown rapidly, problem of environmental pollution caused by pig raising waste excretion, which also becomes, hinders China's live pig industry can
An important factor for sustainable development.Fermentation bed to raise pig technology is to comprehensively utilize microbiology, life using completely new natural agriculture theory
State, Fermentation Engineering principle, a kind of environmental protection using active function microorganism as matter energy " conversion maincenter ", safely, have
The ecologically raising pigs mode of effect.Fermentation bed to raise pig technology is a large amount of to be inoculated with as a kind of pollution-free, zero-emission organic agriculture technology
Probiotics and pig manure in normal flora constitute fermentation bed dominant microflora, with crops such as sawdust, wheat bran, rice husks according to certain
Ratio cooperation be used as padding, after fermented, in fermentation bed ira situ degradation, consumption fecaluria.
In traditional cement floor pig house, odorant caused by pig manure fermentation up to more than 160, these odorants
