At colostrums duly watering within 1-4 days a dominating microorganism in intestines becomes Lactobacillus bifidus, besides colostrums and milk contains some factors stimulating growth of this microorganism and warning undesirable growth of pathogenic microflora. After transition to final type of a feed genetically determined becoming of immune system of thin intestines mucous membrane under influence nervous, endocrine and immune signals optimum regulates digestion, absorption and a constancy of the internal environment at observance of sanitary-and-hygienic conditions of calves and pigs cultivation.
