The Isolation, Identification Of Probiotics From Fowls And Studies On Their Biological Traits And Initial Application

China is the biggest meat-producing and fowl-cultivating country in the world. But meat export is only 0.9-1.2% of the total amount of its production. The two main reason of restricting export of livestock and fowl products were medicine remains and the polution of causative organism. The study and application of anti-infection reunion microecological preparation can substitute antibiotics and decrease medicine remains in one side; In the other side it can control the pathogenic microorganism infection and improve the survival rate of young animals and reduce the diarrhea and enteritis.Viable organism preparation has been applied extensively in the world. Its main function is promoting the absorption of nutrition in feedstuff , promoting animals'weight-getting and growth, preventing young animals'diarrhea, increasing feedstuff transformation efficiency and feedstuff reward and improving the immunity and antimorbific capacity which can not be substituted by medicine additives.The study of viable organism has been developed greatly these 20 years. But the elaboration,use, conservation and transportation of viable organism will make bioactivity down. Meanwhile, some strains cannot counteract HCl, bile salt etc. when they go through the circumstance of low...
