Abstract:In order to determine the effect of the pig intestines probiotics II solid-state fermentation,and the effect of compound probiotics preservation conditions on different living bacterium number,pig intestines probiotics Lactobacillus casei,Lactobacillus reuteri fermentation were solidified,the number of bacteria,and then live in certain proportion will be two kinds of probiotics and liquid fermentation of freeze-drying Bafillus natto sieved flour into composite probiotics,determination of the preparation room in 4 degrees and preservation condition within 14 days and half years probiotic bacteria living quantity changed.Within 14 days of probiotics,temperature conditions living bacterium number increased,and gradually decreased beyond four degrees of preparations for preservation living bacterium slowly decreased.Temperature preservation condition of probiotics living bacterium,4 ℃ and preservation of degrees of probiotics death rate than the temperature preservation slightly slower,but the difference was not significant(P> 0.05).After six months of two ways to save the probiotic bacteria living bacterium number count results respectively 109 CFU/g,1.3 ×109 CFU/g,1.5×109 CFU/g live probiotics bacterium more than 3×108 CFU/g,can were still in use.Research showed that the compound of probiotics at 4 degrees Celsius temperature and lactobacillus conditions can retain activity for more than six months.
Keywords:swine  probiotics  Lactobacillus casei  Lactobacillus reuteri  Bafillus natto  keeping time
