| Colostrum contains a variety of immune active factors and growth factors, It has attracted increasingly widespread attention in the field of animal and human health. It is called the "King of immunity", and "milk of gold". Also, it has become a new generation of functional food resource。Research of Colostrums was studying further and further in these years. Until1990, scientists began to be concerned of the development of Colostrums in the perspective of functional food. We consulted and sorted out a large number of reports and they showed to us that Colostrums can regulate intestinal flora to make human bodies keep balance. However, the healthy function of Colostrums was largely disputed in the diary industry. To some extent, it limited the development of the industry of bovine colostrums.The main purpose of this research was to verify that bovine colostrums, milk Po (Infant formulas powder adding Colostrums), Ruzhen (oral immune immunoglobulin), Milk product in solids (including Colostrums), Mongolian milk slite can play a role in inhibiting the growth of pathogenic enterobacteria in vitro. This research can lay a theoretical foundation for the development of colostrums immunoglobulin.In this part, we mainly research on the effects of bovine colostrums, milk Po Infant formulas powder adding Colostrums), Ruzhen (oral immune immunoglobulin), Milk product in solids (including Colostrums), Mongolian milk slite on the inhibition of in vitro cultured intestinal pathogenic E. coli, Staphylococcus aureus and vibrio parahaemolyticus. we divided our research into different groups. The bovine colostrums, milk Po (Infant formulas powder adding Colostrums), Ruzhen (oral immune immunoglobulin), Milk product in solids (including Colostrums), Mongolian milk slite were in the testing group. They were compared to control group and identified the effects on inhibiting the growth of intestinal pathogenic E. coli, Staphylococcus aureus and vibrio parahaemolyticus in vitro, respectively. |
